During a tournament, we have three 2 and a half minute rounds, so does your points just get added together and become your total points. Also can you modify your bot between rounds to do different tasks.
- Message by: Eco-Nuts 10/07/2002 16:36:07 GMT
Bulldogs,
No your score is not added, each round is independent of the others. You have 2 and a half minutes to get as many points as possible. Each tournament has their own rules as to how the winner is selected. Some just look at the highest score from all 3 rounds and in the event of a tie go to the next highest for the tied teams. Other tournaments will use the highest score to rank the teams and then have a play off to determine the winner. Either way each round is independent of the other rounds.
Yes you can modify your bot between rounds. You can change your bot during the 2 and a half minute round (most people do).

- Message by: C&W Urban Knights 09/28/2002 13:15:29 GMT
Do you mean in New York City? In the state of New Jersey a person may possess a handgun for the protection of his home or for target practice without penalty if he got it legally. To carry it in New Jersey, a person needs a special permit that is hard to obtain. Students who bring guns or bombs to school get expelled and may be in trouble with the police. That is my understanding of our laws in the state next to New York. Are you planning a security robot?

Very, very few people bring handguns or bombs to school. Those who do get into big trouble. Many schools have metal detectors and police officers. My children school at home so I feel they are safe. Many schools don't allow metal silverware or any kind of knife. My children use knives and other sharp things at home. They are part of a gun safety program and have learned to shoot well. Does anyone know what the rules are in New York?

There're a couple of problems in Singapore, mainly problems over environmental factors and air pollution. There have been a breakthrough lately in solving the problems in water shortage in this small island country.
There're 14 reservoirs in the country, and a lot of catchment areas have been lost during the settling down of the people in the early part of the 20th century. The country have devised a method in turning sewage water into clean potable water known as NeWater. More information regarding this topic can be obtained from http://www.pub.gov.sg/NEWater

There are certain topics that doesn't account to much attention that can be solved by robort technology. Vehicle pollution and noise sources from polluting vehicles is a very good topic for a robot to tackle.
Certain vehicles in Singapore does not abid the law of not having too much vehicle exhaust or noise defenders fitted onto them to reduce the amount of unwanted distractions.
Certain expressways or roads in Singapore have a system called the ERP, known as the Electronic Road Pricing, to reduced congestion at known areas.

Are coaches (or librarians) allowed to suggest web sites to their team that may be of use in the research assignment?-- Team Tiki Jackie Keith
- Message by: ilsgreen 09/21/2002 03:38:56 GMT
Team Tiki:
Yes, coaches, mentors, librarians, teachers, etc., may suggest web sites.
Ultimately, teams need to do their own work. However, this may be the first time that your team members may have done this level of research, so there can be some teaching here. Helping to provide tools and sharpen library skills is perfectly acceptable. This would very similar to teaching basic mechanical and programming skills for the robotic competition, even though the team will do their own design and programming work.

Last year it was 3 minutes for the research presentation.
Don't know if that applies this year or not, but would be a good basis to start with for your presentations.
Our experience about how it worked was we would give our presentation, then the judges would ask questions and look at everything. This was normally in a room away from the competition. No other teams were present for that part.

Review the awards section. Winning with the robot only gets one award. The other awards are for different aspects of the challenge. The presentation is only one of the awards. You are encouraged to participate and try for all the trophies with the largest trophy going for the Directors award. This award is for the overall challenge, the one that has demonstrated the highest overall "score" for each of the other award categories. Some teams will only go after the robot competition trophy by concentrating only on how well their robot will do the day of the competition. Others will concentrate more on the presentation, and others will do it all. It is your choice as to where you will spend your efforts. Each award is independent of the others except for the Directors award.

Question asked:
A question has arisen in the Forum about which cities can be used for the research assignment. The getting started states "You can choose your own city or one among the City Profiles". We would like to know if that means we can only choose from the city profiles and the city we live in or are we free to choose any city in the world?
Response from FLL:
The intent was for you to use the city you LIVE IN (or one of those profiled), so your local judges could be as prepared as possible. But due to the double meaning in the wording, many people just thought it meant pick a city of your choice, any city, so they did.
Bottom line: If you already have time invested in a city out of the blue, you should continue with that, otherwise please pick the one you live in (or one of the ones profiled).
Sorry for the confusion,

This info was mailed to me from our Ohio FL org. It is posted on the web site listed. When I read it I was in shock so were the kids. I was not planning on something 15 mins. long. For a Rookie coach this is a lot more than I thought it would be when I signed up!
Research Presentation Information
I have had a lot of mail requesting information about the Research Presentation... specifically what, where, when, why, and how!
So... here is the short version.
The Research Presentation is a total of 15 minutes long. Your students should prepare a 7 - 8 minute presentation, and the judges will use 7 - 8 minutes to ask questions. Your presentation should include the name of the city you chose, the background research on that city (as an example see the city profiles from FL), the problems facing that city, the one problem you selected to find a solution for, and a presentation of your solution using technology. Include in your data how cost-effective this solution would be and what would be gained by implementing your solution, as well as a draft of the technology needed.
Part of the judging for the Research Presentation is based on how many different kinds of sources you used. i.. - if you used the interned and nothing else you would probably not get a very high score in that area. I would strongly suggest that if you choose to use your own city that you contact an Urban Planner or City Leader in that city and request a face-to-face visit to discuss the problems.
Adults other than the judges are not allowed in the presentation rooms.
Computers and other electrical equipment will not be provided in the presentation rooms. Teams may use hand-held graphics or props, flash cards, signs, etc.
A laptop computer may also be used. If a laptop computer is used, the team must set it up themselves.
The time for set-up of equipment is part of the allotted 15 minute timeframe for the Research Presentation.
Teams who miss their scheduled presentation time will not be rescheduled.
Teams are strongly urged to practice the Presentation, including who starts to speak first and what each person says and does. Creativity is a plus.
This is an excellent opportunity for your students to work on a real-world problem in your city AND meet with city leaders to present their solution. Consider the assignment as if they were real engineers being asked to find a cost-effective way to solve a problem.
I hope this helps. Research and Technical presentation guidelines are listed on the Ohio FLL website http://www.asccxe.wpafb.af.mil/Robotics/index.htm
The judging rubrics should be online by the end of the week.

15 minutes x 40 teams = 10 hours. Some places take 70 teams, thats 17.5 hours. I do not think this will be the norm. It is up to the individual tournaments to decide how much time will be alloted. Last year the tournaments I went to only allowed 2.5 minutes which is not long enough. It will be interesting if to see what other tournaments are doing.

Each state has different rules. The Ohio 7-8 minute research presentation length is certainly longer than the 3 minutes in Wisconsin. Parents have also been allowed into the scientific presentation in Wisconsin in the past; however, parents and coaches were not allowed in the technical presentation session for robot and programming judging last year.
Hopefully, the 7-8 minute presentation in Ohio gets a review. It's a bit long for the age group, particularly with student not used to getting organized to speaking or even writing much beyond a few paragraphs on a given topic.
And do remember to keep it fun and have kids keep learning. Much like the robotic challenge, not everything will be perfectly in place for any presentation.

In Arkansas for 2000 and 2001, we had about 3 minutes for our presentatation. Then the judges asked the kids questions. Each team was taken aside sometime during the day to a room that was away from the rest of the action. They were using a school, so had several different classrooms. Each team who had display boards, models ect, were allowed to set those up in advance at the start of the day, then the whole team, including adults, came back for the presentation when it was that team's time.
They had several different rooms they used, each with a different sets of judges, so they were doing more than one interview at a time. But not all the teams did research.
For 2000, three judges were present for our presentation. But for 2001 there was only one judge who listened to our presentation, no other judges were present. I thought that was a bit odd since most of the other teams during the day had 3 present during their time slots. But perhaps because they had about 50 teams, that was the only way they could get to everyone in a reasonable time.
I find the rules for the Ohio presentation a bit different since they don't allow the adult coach to be present during the presentation. We not only had our coach and mentors present during both years, but the parents of team members were also there. They didn't seem to have a problem with that since it was the kids who were doing the talking. The adults just sat quietly in the room.
Anyway, both times it was fairly informal. The judges were very nice to the kids. The kids did well but they had practiced in advance what to say. We also did some test runs where the adults would pretend to be a judge and come up with possible questions. It was helpful for the kids to decide in advance who was going to speak. Last year 2 of the kids were our main speakers, one in front of each display board that we had brought. The rest of the team filled in some additional information on some of the questions.

Operation Stanley,
Please keep in mind that I'm a rookie, so the info I share may be incorrect. Elsewhere in this discussion I believe it was stated that details like judging and such are determined by the your state FLL organization. That is where the most specific info I have came from, our Ohio FLL. I see by clicking your icon that you are in Michigan. I went to the side bar of this page and clicked on teams and tournaments. I selected Michigan and was directed to the Michigan tournament page where there was a link at the top that said something like "everyone read this." In that message was a link to the Michigan FLL. I clicked that and saw many links of interest including a link about judging that said "coming soon." I also saw links to last years tournament that had a reference to judging. I would think that would help. Perhaps last years info would give you some idea of what to plan for.
I hope this helps and is correct. I am about one inch ahead of you on the mile long line to ready for the presentation. May you be blessed with a judging rule that states your presentation should be shorter than the 7-8 mins we have to give. (I am still in shock over that one)

If you down loaded the info on the research assignment you know that in section V. Anatomy of a Research Assignment it states "The Research Assignment helps city planners design a solution, using robotics technology, which assists in bringing a basic need to city inhabitants, such as clean water, clean/safe environment, shelter, or transportation to name a few."
Does the social problem qualify as a basic need?

Just have one or two of the members be your primary speakers. Have them practice their presentations ahead of time. What you want is to have them give a brief summary of what you did and what they learned. The other team members can be supportive and add comments when needed, but it just makes it more focused if you have one or two students do most of the talking for that part.

The mission page only says knocking them down. So if you can move them without knocking them down go ahead. Remember that the duloc might be different at the tournament then on your setup. So it might take more or less effort to remove the bushes from the duloc and place them somewhere else. Also placing them on the mat will not be a very steady position. The duloc bottom is not all that flat.

Welcome aboard Eagle Engineers,
The presentation is one more way that the kids compete in a tournament. It is considered a very important aspect of FLL and the winning team is usually awarded one of the larger trophies for their efforts.
The presentation is meant to help kids connect the fun of building toys to a real world challenge. It is the scholastic achievement amidst the thrill of lego robots. This year's challenge is themed around the problems most cities face... be it trash removal, transportation, clean water and resources or the repair of major structures. As part of their challenge, teams are to choose a city from the list given (or maybe their own home town), research that city to come up with a list of current day issues(problems), and as a team choose one of those problems that may benefit from a robotic solution... such as a non-manned trash/garbage collection system, or maybe a computerized transportation system for crowed sidewalks... etc.
They spend time brainstorming ways to correct, improve or creatively solve a current-day problem into a working if not off-the-wall solution. They are given a finite amount of time to present their solution to a panel of judges who grade them on content, creativity, overall understanding of the problem, their method of determining a solution and how it is all presented (among other things). It can be very elaborate or it can be very simple. If it looks like it was thrown together at the last minute (which can easily happen in Lego League :-) then points will be awarded accordingly. Posters, banners, models, even skits are sometimes used to present their solution. The sky is the limit. They may do it any way they like. They are only limited on how much time they have for their presentation. Usually two or three minutes. There is usually a short question and answer period by the judging panel and that's it.
This is an overall explanation but you should be careful to read the FLL presentation rules and information to be sure I haven't left anything out or maybe led you astray.
I actually had one of the parents of the kids come in and help put this together with half of the team. We were pressed for time and the programmers were really focused on correcting problems.
That's one thing I will mention. The builders are usually finished before the programmers. At some point the kids need to decided the building is done so that the programmers can solidify their programs and finish the challenges. So you can have builders standing around with their hands in their pockets near the end of the season. These guys can make posters or work on the presentation to keep themselves busy.
I hope this all helps. I'm sure I raised more questions than I answered but feel free to ask more.
Again... WELCOME ABOARD!

It's really up to the tournament director. They usually give that information (tournament directions, instructions, clarification of rules... etc.) to you when you have been accepted to a tournament. But generally it is only a few minutes long... say two to five minutes. Afterwards the judges may spend a few extra minutes asking questions and then it's over. If extra time is desired I would merely clear it with the tournament director ahead of time. I'm sure there would not be a problem.

General rule of thumb is that you would be provided with electricty. But anything else, such as overheads or projectors you would need to bring your own.
If the competition is at a school, most of the time the judges will take teams into various classrooms for the presentation part. They normally have more than one going at the same time, so it would be too confusing for them to try to set up multiple rooms with equipment.
Sure you could do part of your presentation on a laptop, but do plan on bringing your own screen.
What you should do is check with the specific competition you will be attending and find out what type of set-up they have in mind for the presentations.
- Message by: B.O.B. 11/03/2002 08:37:44 GMT
Oh Columbia if you are going back to Arkansas again, they do the presentations in classrooms just off of the staging area at the High School. When you check in, tell them you will be doing a presentation. They had 3 or 4 sets of judges that went around doing the presentations throughout the day.
We brought presentation materials there for 2 years, each time they had us set up in advance in a classroom, then called us when the judges were ready to see our presentations. We had models, tri-folds, display boards that type of thing.
I wouldn't count on a projector, bring your own.
This year we'll be in Houston and have alredy been told other than electricity, we will need to provide our own equipment for the presentation part.

We're very uncertain how to help our students understand what this research is about. At this time, they seem to want me, the coach, to tell them what to do, and I feel the point of this component is for them to brainstorm and come up with a problem and a solution for themselves.
HELP! I just don't know what to ask them, or tell them that will help them accomplish this for themselves.

For my team, I am suggesting that they choose our local region. Then they are scanning the newspapers for a couple of weeks to see what are the current concerns and issues facing our community. Next we will talk about which concern we would like to "solve" and begin to brainstorm resources for information on possible solutions.
For example, our area is experiencing a severe drought and a limited water supply (no river feeding the lakes, only rain). The team is very aware of this issue and is considering it as our problem. If this is what they choose, we will then schedule a field trip to someone in the city water department and begin there.
Hope this helps.

On the lego table,do the cities have to do with the table layout?
- Message by: Eco-Nuts 10/10/2002 19:25:18 GMT
The cities do not have anything to do with the table layout. The table layout is a hypothetical city layout that allows us to experience some of the dificulties that would be faced with an autonomous robot trying to do these types of tasks.
The project on the city is to gain more understanding with the problems that face cities and to think of ways that a robot could improve things.
You do not have to do the project, but would be recommended as this is part of the whole experience with FIRST. It is not just a sports competition. It's about thinking and learning about technology and how technology can be used to reduce the workload of humans and do tasks that are either too dangerous for humans or too mundane for humans.

Please advise.
In terms of using technology, the word use in the intstruction is 'robotics'. Does it means use of a robot or just automated/programmed machinery; such as traffic lights for pedestrains: 30 secs to walk and when it reached the 15 secs, the warning sound alarms to indicate green man is turning to red man soon - Is this consider robotics?
Also, can coach comment or reply to messages seen in discussions? Or only by the children?
Advices are greatly appreciated.

The forum is set up for both kids and coaches. Most of the coaches are asking and answering the questions relating to the game and rules. Most of the "chit chat" is from kids. I treat all questions the same wether from a coach or kid, I usually do not know which and will answer as best as I can. As for robotics question, you can use whatever you would like to interprete it as. The most important thing is the thaught and creativity that when into it and not the final technology you came up with. However, since this is a robotics competition and more specifically an autonomous robotics competition, it would be more in the keeping with the rest of the competition to show how an autonomous robot can be used. But this is not a requirement.

Are there any restrictions on "how" you get the Windmill to spin? Do you have to make it spin by moving the arm?
- Message by: RoboSquad 12/01/2002 00:08:00 GMT
Are there any restrictions on "how" you get the Windmill to spin? Do you have to make it spin by moving the arm?
Read the mission statement and the rules. Do they say anything about how to get the windmill to spin? No, so what does that tell you?
Note however that the arm holds a piece jammed into a gear to keep the windmill from turning. Without moving the arm, you'd have to do some very careful dismembering of the mechanism to unjam the gear without damaging the rest of the windmill to the point it won't spin. Note also that pieces may be glued together at tournaments, so you can't rely on them coming apart in the typical Lego manner.
- Message by: Eco-Nuts 11/28/2002 00:27:45 GMT
The rules do not indicate how the windmill must spin, just says to get the windmill to spin. Be creative, that is why the rules have some wiggle room in them. If they wanted you to hit the bar, then that would have been spelled out in the mission. So no there are no restrictions on how you get the windmill to spin. However, the arm is in the way for one direction which requires you to move the arm in some fasion to allow it to spin in that direction. The other direction is to wind it up more and that may not be easy since you have no way of knowing how tight it already is. Knocking down the windmill might make it spin, and then it might not, depending on how it came down??? So be creative and after the tournaments, I would be interested in what you came up with.

Discussion: Starting the Research Assignment -----HELP!! By: Bob's Builders 11/19/2002 07:16:36 GMT
Hey Everyone, I'm Kristen from Bob's Builders and I am in charge mostly, of the research assignment. I, along with my team does not understand the research assignment.

The research assignment is one more way that the kids compete in a tournament. It is considered a very important aspect of FLL and the winning team is usually awarded one of the larger trophies for their efforts.
The presentation is meant to help kids connect the fun of building toys to a real world challenge. It is the scholastic achievement amidst the thrill of lego robots. This year's challenge is themed around the problems most cities face... be it trash removal, transportation, clean water and resources or the repair of major structures. As part of their challenge, teams are to choose a city from the list given (or maybe their own home town), research that city to come up with a list of current day issues(problems), and as a team, choose one of those problems that may benefit from a robotic solution... such as a non-manned trash/garbage collection system, or maybe a computerized transportation system for crowed sidewalks... etc.
They spend time brainstorming ways to correct, improve or creatively solve a current-day problem into a working if not off-the-wall solution. They are given a finite amount of time to present their solution to a panel of judges who grade them on content, creativity, overall understanding of the problem, their method of determining a solution and how it is all presented (among other things). It can be very elaborate or it can be very simple. If it looks like it was thrown together at the last minute (which can easily happen in Lego League :-) then points will be awarded accordingly. Posters, banners, models, even skits are sometimes used to present their solution. The sky is the limit. They may do it any way they like. They are only limited on how much time they have for their presentation. Usually two or three minutes. There is usually a short question and answer period by the judging panel and that's it.
This is an overall explanation but you should be careful to read the FLL presentation rules and information to be sure I haven't left anything out or maybe led you astray.
I actually had one of the parents of the kids come in and help put this together with half of the team. We were pressed for time and the programmers were really focused on correcting problems.
That's one thing I will mention. The builders are usually finished before the programmers. At some point the kids need to decided the building is done so that the programmers can solidify their programs and finish the challenges. So you can have builders standing around with their hands in their pockets near the end of the season. These guys can make posters or work on the presentation to keep themselves busy.
I hope this all helps. I'm sure I raised more questions than I answered but feel free to ask more.
Again... WELCOME ABOARD!

I'm confused by the search team webpage function, it doesn't seem to yield very many results.
For example, I know from viewing the Teams and Tournaments page that their are quite a few Texas teams using the forums. But if I search on the keyword of Texas, only one team shows up.
Exactly what part of each team's webpage does it search on?
I also can't seem to search by teamname, I tried putting in our Team's name and got zero results.
Also when I am in the forums and click on a team name, it seems to give more complete results than if I am at the Teams and Tournament section and click on a team name. In the majority of cases for Teams and Tournamets, clicking on a team name will only give the email contact. But if you click on the team name in the forums, then you get the more complete page that includes the description of the team. Why is it different in the two places?
Is there some sort of setting to check to make it such that if someone tries to display your team info from the Teams and Tournaments section it will show more complete details?

The site works OK in Netscape 7.0 (and thus probably Mozilla), but is extremely slow to load even over my DSL line.

When I click on "Search teampages" and type in our team name "badgerbots" it says it cannot find it. When I click on "Your team Page" link I go to a page that wants me to put in information about my team.
I must be real dense. This seems terribly complicated. Is there actually a web page for our team or do people just go into our team page and read what we typed in the predesignated blocks?

Hi there
Your rigth, click the botton next to login, named "Your Teampage", you can write about your team, by answering the questions, upload a team picture, tell things about your robot, give other teams cool links.

But I'm still confused. If we cannot go to "search team pages" and find our team how does this provide any value? I'm expecting to fill in the stuff you are talking about and then go to look at how it shows up to others.

You should be able to find your team in the "search team pages". It may be registered with an incorrect name so you may try variations of the name or just the first few characters.

I have been through your team page, and saw that you had
not completed the process, but it could seem a little tricky, here is some help.
6. Steps to complete Team Page
1. Click "Preferences"
2. Fill in the information you want to show.
3. Click "Set Preferences"
4. Look through the information, to see if you have missed
anything. If you have missed something, use the browse
back button in your browser. and repeat step 3.+ 4.
5. Click "OK"
6. Now your teampage is up and running, and you can access
it from the "Search Teampage"

Jacob-
I am coaching team #2301, the 'Surfbots'.
After completing your six steps' for registering the team home page, only the mail address is reported for the team information. The team's name cannot be found in the search engine, nor is it listed by searching under 'Florida'. (I completed the PREFERENCES|SET PREFERENCES|OK sequence numerous times.)
There is another strange phenomenon. Look at the tournament page for Florida, and specifically, the links for the listed teams. The hot-link for some teams is a 'webx.dll', for others it is an 'index.asp'. The four teams that correctly generate information (Avatar picture and text) are all using a webx.dll. All of the teams that link to the index. asp generate space information. Is there a server-push that translates the preferences page into this web content? How can I get the server to perform this update? Is it possible that I registered for the Florida tournament before the my preferences were set, and the automatic web page generator for the tournament never went back to process the link change?
Thank you in advance for the help.

No it doesn't.
I use Mozilla as my primary email browser, however I could not use Mozilla AT ALL to get into the forums. It just displays a blank page. I tried it several times on more than one machine for several days. I can use Mozilla to view the challenge but it does not work at all to get into the forums. Never can get the page to display that lets you enter your team name and password, it's just empty.
Also when FLL sends links that are specific to an area in the forums, I also get a blank page using Mozilla. I tried it again today, same thing, won't work for Mozilla.
So I've been forced to use IE if I want in. I used IE last year as well for the forums because it didn't work as well using Netscape.
Our main mentor uses Mozilla on a Linux machine. He can't get into the forums at all from there either. He has to go over to a Windows machine and use IE if he wants to get into here.
I suggested for next year that FLL please try to make it work on Mozilla. By next year AOL will probably be using Mozilla, they are switching to that as their default browser. Mozilla is also less prone for viruses than IE or Outlook.

I've had similar difficulties using Mozilla. When I tried to login to the forums, I would just get a blank page.
I was able to work around this problem by logging in using a browser that works and then cutting and pasting the URL from the working browser into Mozilla, and then bookmarking the page in Mozilla so I can go directly to the forums while bypassing the offending page. So far I've been able to use the forums using this technique in Mozilla without trouble.
I second your suggestion that FLL try to make the website more friendly to non-Microsoft platforms. The use of proprietry formats (Microsoft word) and flash graphics as well as the non-standard HTML makes visiting the FLL site a very unpleasant experience for me.

Discussion: Light Sensor By: obgsc robotics 12/06/2002 06:49:55 GMT
I am a first-time mentor trying to help my team use the light sensor.
As I recall from our training session, the light sensor returned readings from about 50 to 75, depending on whether it was pointed at light or dark.
However, we tried various sensors on different ports yesterday and were getting readings around 530. We couldn't get it to vary between light and dark more than about 10 points. Also, we are using the RIS software, which allows settings only from 0 to 100, so readings > 500 don't work.
What am I missing?
- Message by: Harris 10/23/2002 01:26:22 GMT
This could be because the RCX doesn't know you are trying to attach a light sensor. Before you can see reasonable results you must download and run a program that references a light sensor on the port it's attached.
From the empty program block I usually grab a WaitUntil block, open the config wizard (button on the side of the stop sign) and select Light Sensor, Bright, ...
Download and run that program. You can now use the view button (black button) to select the port with the light sensor to see what the light sensor is reading.
With the light sensor 3-5mm from the mat and normal room lighting (no overhead table light) I usually see values of 32 - 50 (dark line -- white)
Hope that helps.

- Message by: B.O.B. 12/01/2002 19:36:33 GMT
Yes, it's a change from last year. For prior years you could only use parts from the kit. But not this year.
When the challenge was announced for this year back in Sept and the rules were published on the website, that was one of the rules.
Each FLL team member should have read the rules to become familiar with what is allowed and what is not. But based upon the questions I'm seeing the forum it's clear many teams are not reading the rules carefully. Many of their common questions can be answered by simply reading the rules and the updated Q&A section of the FLL website.
It's also in the coach's manual on page 55 that was shipped with each team kit. (Tournaments and local event section)
And look at the Q&A section of the FLL Website, that question was posted way back in Sept:

Q: The rule on allowable parts says we can use any LEGO, except for the electric exceptions, but can we use pneumatics, Star Wars, etc.?
A: Yes. Any parts really means any parts. It's a huge change from the past, so teams are having trouble believing their eyes---but it's true.

Check with whatever event you are planning on attending, but I haven't heard of any that limit the number of spectators. Most events would want people to come watch in order to promote FLL more.

How do you use the find dark thing?
- Message by: Harris 12/18/2002 21:51:27 GMT
This sounds like the 'Find Dark' big block. You probably don't want to use that. It's a program that tries to get the robot to point in the direction where the light sensor see's the least light.
Instead you probably want to use something like the Wait Until light sensor sees dark. E.g.
Turn ON both motors to get robot to go forward
Wait Until (light sensor 1 sees dark)
OFF both motors
When you run this the robot should drive forward until the light sensor attached to input port #1 sees dark. Of course this assumes that there is a light sensor attached to port #1 and that it's pointing down so that it can see the dark lines on the mat.
The training missions may also help you to better understand how to use the sensors. One other piece of advice, do not use the sensor watchers, because of the way the work it's hard to predict your robots behavior.

How do you make a lift? WERE DESPERATE
- Message by: Harris 12/18/2002 21:54:37 GMT
This is for the material delivery right?
Is a lift the ONLY solution? I'm sure there are other ways of solving this. Try to think of some different ones. The mission only states that you need to deliever the material to the highest floor for the most points, it doesn't say that the robot must lift it from the ground to the highest floor, it just has to be on the highest floor to get the most points.

Discussion: Having problems downloading firmware to RCX By: Intelligent Community 12/18/2002 14:01:06 GMT
we tried to set up the IR Transmitter to download firmware but the RCX was not responding.
We tried the following steps to get it to work:
turning off the room lights
we tried fresh batteries
we shortened the distance from the IR transmitter and the RCX
we tried turning the RCX on and off
we restarted the computer
we changed USB ports
we had no success
- Message by: ilsgreen 12/13/2002 20:41:01 GMT
- Robolab or RIS?
- Has downloading worked in the past?
- Is the communication within Robolab or RIS set up to use the USB port?
- In Robolab, USB tower recognition required an additional file to be read from the CD disk to get the USB IR tower to work. (I suppose there is an equivalent in RIS, but I don't know). Has this been done?
- What operating system is the computer running?
- Do you have a green light showing when the IR tower attempts to communicate with the RCX?
- What error messages (if any) appear on the computer after downlaod is unsuccessful?
- Every now and again, there is a bad RCX or IR tower. Do you have the option to try a different RCX or IR port?
- PITSCO can be good with technical support. I had a problem with a serial IR tower last year and was able to get a replacement for free. I couldn't get a green light to appear on the tower. Fortunately, it was early in the year for me.

Mark,
Thanks for your response. I will answer your questions in order. In answering the questions, I hope to be able to diagnose the problem.
1. We're working with Robolab 2.5.
2. Communication is set up to use the USB port.
3. AHA! I am not aware of any additional file that has to be read from the CD disk. This HAS NOT been done. I suspect this is the problem. What is the name of the file to be read? Also, the CD was NOT in the computer while we were trying to download the firmware.
4. We're working on a Mac, OS 9.2.
5. We do see a green light showing when the IR tower attempsts to communicate with thr RCX.
6. Unable to give you the exact error message at this time.
7. We DO have another IR port snd another RCX which we could try.
8. We are just beginning to program. I appreciate your helping us to solve this problem. We'll write back on Tuesday 12/17/02.

Marilyn, I have a lot more experience with PCs rather than Macs, so my help may be limited. I have installed Robolab 2.0 on an older Mac (pre-iMac) using a serial IR tower for last year's programming, though.
As for the additional file for the USB tower within Robolab, I did install Robolab 2.5 on a PC last month. However, I did not have the tower attached to the PC when installing Robolab 2.5, and my first try with the USB tower did not recognize a USB port. Installing the USB tower driver required both the IR tower attached and the CD install running on the computer. I'm not sure on the file name installed, as the PC installed the driver automatically once the CD was in and the IR tower was plugged into the USB port. I'm not sure about Macs, as I've only tried a serial IR tower on a Mac rather than a USB tower.
Another possible problem specific to Macs is not having AppleTalk disabled. For details, see http://www.lego.com/eng/education/mindstorms/home.asp?menu=support&pagename=support, then look for the Macintosh troubleshooting information. Additional helpful information is also elsewhere on this site, I recommend reading through the FAQ and the PC troubleshooting as well if you haven't seen this before.
The green light showing is good, as the IR tower should be able to communicate with the RCX. Trying the other RCX might be a good idea.
Lots of fluorescent lighting can also affect IR communication. We fought too much lighting at one practice this year. You might try putting the tower and RCX under a box to block the lighting.
If nothing else works, the people at PITSCO can also be very helpful via e-mail or a phone call. I had a bad serial IR tower last year which they graciously replaced after the normal troubleshooting methods could not solve the problems I had with my tower.
Please keep us posted on the ultimate solution, as coaches and menotors really have better thing to do than fight equipment issues like this!

One last thought - the RCX needs to be turned on to download firmware or programs. I am 99%+ your team has done this, but it's surprising how often through the year that a download gets an error message because the RCX was off! - Mark

Mark,
I've been re-reading materials and maybe ApApple Talks the problem, So, I'll turn it off when we try again.
The RCX was on, but I'll tell you where power might also have been an issue: The computer (an iBooBooks running off of battery power*not connected to the wall.
The old IR towRI was powered by a 9-volt battery. The USB toSUB gets its power from the computer. It's possible that the IR towRI connected to the laptoplap tophe USB poSUBneeded more power than could be delivered from an unconnected device. So, tomorrow, I'll run the computer from an outlet before trying to downlodown loadafirm ware.ks for helping me think this through.

Hi Mark,
We learned many important lessons:
Problems are great learning experiences.
We learned the value of community. We learned the value of email to share resources across distance and time. When we met, the team members wanted to know if ANYBODY responded to our plea. They were very surprised that a team from Wisconsin helped us. Thanks to the FLL International Forum! Thanks Immanuel Lutheran School Teams, Thank you, Mark.
Needless to say we learned many lessons about science thinking, problem solving and technology.

Discussion: Suggestions for FLL Website By: Pennichuck 01/10/2003 18:21:55 GMT
Well... its the end of another year of FLL.
I appreciate the work that has gone into
organizing this effort.
I have a few suggestions to improve the
usefulness of the website and the FLL
documentation.
1) Skip the flash animations. They take a long
time to load, require a separate download ('you
need a newer version of the flash plugin'),
and make finding things more difficult than just
using simple links.
2) Make all documention available in standard,
well supported formats (pdf, or html). Don't
document things in MS-Word document formats, it
requires software that is not available to all.
3) Make sure all parts of the web are accessible
with standards conforming browsers (mozilla,
opera, netscape), not just IE. I was unable
to access the forums using my browser of choice
(Mozilla).
4) Package things up so I can download everything
I need at once (all the build instructions,
rules and mission descriptions).
Thanks

2002 CITY SIGHTS - TOURNAMENT TERMS AND RULES
1) T*L*CHARGEMENT : Pour *viter d*effacer des programmes, on permet seulement le t*l*chargement * courte port*e. Le processus doit *tre prot*g* des *quipes environnantes et le RCX doit *tre tenu * distance quand il n*est pas utilis*.
2) PROC*DURE DU TOURNOI : Lors du tournoi, deux pistes sont jointes et chaque *quipe a une partie * sa disposition. Chaque match dure 5 minutes et les parties s*encha*nent en continu.
Il y a d'habitude 4 rounds * un tournoi, avec des parties arrang*es pour *viter d*avoir les m*mes adversaires. Pendant le temps entre les rencontres, l'*quipe peut aller * la piste d*entra*nement et changer, ajuster le robot et les programmes. Le score obtenu sur un match n*est pas d*finitif. Quand toutes les *quipes ont r*alis* leurs matchs, le meilleur score de l**quipe sur une rencontre est pris en compte pour la suite de la comp*tition (meilleure performance de robots et qualification aux phases finales).
3) MISSIONS : Pour chaque rencontre, les *quipes essaient d*accomplir les missions quelles veulent, dans l*ordre quelles souhaitent, sans avoir l*obligation de toute les faire. Une mission est consid*r*e comme d*marr*e si un *l*ve a appuy* sur le bouton vert du RCX. Pendant que le programme s*ex*cute, le robot est consid*r* comme r*alisant la mission m*me s*il reste dans sa base. D*s que le robot est touch* * nouveau, la mission est consid*r*e comme termin*e qu*il soit dans sa base ou non.
4) PARTICIPATION : Seuls deux membres de l**quipe ont le droit de venir contre la piste de comp*tition. Ces *quipiers peuvent changer entre deux rencontres. Quand une r*paration d*urgence est n*cessaire, un troisi*me *quipier sera autoris* mais il devra repartir d*s que la r*paration sera effectu*e.
5) MATERIEL AUTORISE : Une *quipe doit utiliser un seul RCX pour tous les matchs. Un robot est d*fini par tous les *l*ments pos*s sur la base, sont inclus les capteurs additionnels, les *l*ments de montage les projectiles *ventuels, les *l*ments des missions * effectuer. Le robot doit *tre enti*rement fabriqu* avec le mat*riel Lego, sans restriction. Le robot ne doit pas comporter d*autre mat*riel *lectrique que
1 RCX, 3 moteurs , les capteurs Lego par trois au maximum . Le robot ne doit avoir d*autocollants de colle ou d*autre produit liquide ou semi-liquide.
6) LOGICIELS AUTORISES : le robot doit *tre programm* par le logiciel Lego Mindstorms RIS ou Robolab Software dans toutes les versions existantes.
7) BASE : La Base est d*finie comme un espace d*limit* par une bo*te imaginaire d*finie par les limites trac*es et une hauteur de 500mm.
8) POSITION AU DEPART : Chaque mission doit d*marrer de la base. Toutes les positions du robot * l*int*rieur de sa base sont autoris*es. Toutes les parties du robot doivent *tre * l*int*rieur de la base au d*part. Le bouton vert est le seul *l*ment du robot que peuvent toucher les *l*ves pour le faire partir.
9) TRAVAIL SUR LE ROBOT : Quand le robot est dans sa base, sans avoir d*marrer une mission, l**quipe peut le r*parer, le modifier, charger de nouveau programmes, changer les piles etc*
10) CONTROLE DU ROBOT : Toutes les actions du robot doivent *tre programm*es et d*clencher par l*appui sur le bouton vert du RCX au d*part. Toutes autres actions sont interdites. Si un *quipier touche le robot la mission est annul*e et le robot remis au d*part par l*arbitre. Le programme sera re-initialis*.
11) PENALITES POUR RETOUR : Si une *quipe touche le robot quand il a compl*tement quitt* la base (toute partie du robot ayant franchi la ligne) l*arbitre imposera un retour * la base du robot et donnera un p*nalit*. Il enl*vera une des couronnes donn*es en bonus au d*but de la partie. Un robot peut *tre touch* * son retour d*s qu*une partie a franchi la ligne de la base.
12) RECUPERATION D*OBJETS : les points pour les objets ramen*s * la base comptent d*s qu*ils franchissent, m*me en partie, la ligne d*limitant la base ,et cela m*me si le robot est rest* en dehors. Si un *quipier touche le robot revenu charg* avant qu*il touche la ligne, l*arbitre remettra les objets ramen*s en place sur la piste m*me s*il n*y a pas de p*nalit* donn*e * l**quipe.
13) LIVRAISON : Quand la mission comporte une livraison * faire sur la piste * partir de la base, le chargement du robot peut *tre fait * la main par les *quipiers * l*int*rieur de la base. Ils peuvent *tre plac*s dans un * container construit * partir d**l*ments Lego. Dans ce cas les points attribu*s compteront pour le container. Les points seront attribu*s lorsque le temps de la rencontre sera *coul* suivant leur place finale. Les objets qui reviennent avec le robot * la base par ses propres moyens ou par une intervention de l*arbitre, peuvent * nouveau *tre livr*s dans une autre tentative.
14) SCORE : le score est d*finitif * la fin de la rencontre pour *viter toute contestation pendant le match. Les points sont attribu*s en fonction de la place des objets * la fin de la rencontre. Cela signifie que si le robot d*fait au cours d*une mission ce qu*il avait r*ussi * mettre en place, les points ne compteront pas au final.
15) FAUTE DE TOUCHER : Seuls les arbitres auront le droit de toucher les objets, les *l*ments construits et les robots sur la piste. Si un robot bouscule un obstacle, un *l*ment de la piste, laisse tomber des pi*ces ou du mat*riel sur la piste, l**quipe peut demander * l*arbitre de les remettre en place. Les *quipiers peuvent tenir * la main les objets pr*sents sur leur base pour faire de la place.
16) REGLAGES : des cales ou gabarits de positionnement du robot au d*part sur sa base peuvent *tre utilis*s mais ils devront *tre r*alis*s en *l*ments Lego eux-aussi.
17) REGLE IMPORTANTE : les d*cisions des juges ne peuvent *tre contest*es pendant le concours. Si une *quipe a un doute sur la conformit* de leur strat*gie par rapport au r*glement, les *l*ves doivent la pr*senter avant de l*utiliser en comp*tition. Le fait de garder le secret pr*sente le risque d**tre d*clar* ill*gal pendant le concours et ruiner tous vos efforts de pr*paration.

Hey there,
I am from a Lego League team in Jackson, Michigan and I was looking for some pointers also. I am on my home computer and I don't have an RCX here so I can't show you photos of my group's work. on our team we have a mix of different grades(6th, 7th, and 8th graders)and I am an 8th grader. Our team name is the Dynamic Drivers and we are hoping to make regionals. We are very close to being able to complete all tasks but have been getting stuck at the fruit trees.

These questions are dificult to answer. Slow down and ask specific questions. How can "moter" 3 work is not a question that can be answered. It depends on how you have it hooked up. If you are asking how do motors work in the first place, that we can answer. If you are asking how can we control that we need to know which programming language you are using. If you want to know how to make it do something, we need to know how you are trying to use it. As for your other questions, read the rules, review the forum under rules and missions or equipment.

i have a question well our robot can not be taller than 50 cm but could we throw something and if it went over 50 cm would it be leagel/ and if it is could we use that to launch it onto the robot ot the table next to us? Please help us
- Message by: Eco-Nuts 10/09/2002 19:51:52 GMT
You must start out in the base prior to pushing the run button shorter than 50 cm. After pushing the run button, you can be as tall as you want. There are not height restrictions other than prior to pushing the run button at the start of each "mission attempt". So you can throw something that went over 50 cm high. It must be from Lego equipment and must be initiated by the robot and not a human.
p.s. it will be a waste of time to try to hit a moving robot on the other side as the timing and aiming is beyond the RCX capabilities. If you threw something over and landed on the playing field, that side can ask a ref to remove the object at any time.

Discussion: The stacking effect... By: Lego Knights 10/11/2002 21:54:12 GMT
Can you really stack sensors and motors and get the best out of them? I have succsefully stacked sensors, but at the time I was using NQC to program. I wonder if Mindstorms 2.0 software is equip to handle such stacking?
Lego Knights
- Message by: Mindstorms Mayhem 10/11/2002 21:54:12 GMT
Yes, you can readily stack a touch sensor with either another touch sensor, or
with a light sensor.
If you stack two touch sensors (which means to place them both on the same
input port, one on top of the other), then the software will register a "press"
if either sensor is pressed. Note that the software cannot tell which is which,
but it may be that it only makes sense for one of them to be pressed at any
given time. For example, if you have a touch sensor on a front bumper of
your robot, and a touch sensor on the back bumper of your robot, it would
normally only be likely for the front touch sensor to be pressed when moving
forward, or for the back one to be pressed when moving backwards. In this
way, even though the software cannot tell which is pressed, it may be able
to make an excellent guess based upon the context. Other more complicated
situations can be thought up by creative students!
Alternatively, a touch sensor can be stacked on a light sensor. Treat the
sensor as a "light sensor" in the software. (Either RIS or Robolab.) When
the touch sensor is open (not pressed), the value of the sensor is that of
the light sensor. When the touch sensor is pressed, the value of the sensor
will be 100. While the touch sensor is pressed, there is not any way to tell
how much light is present, so one better plan to not rely on the light value
while the touch sensor is pressed! Note that if one were to ever receive a value
of 100 from the light sensor would botch up this arrangement, as the very bright
light would be interpreted as the touch sensor being depressed! However, I have
only seen values of 100 from the light sensor when it was pointed directly at a
bright light source (such as a light bulb or the sun.)

Do any of the lodgings have indoor swimming pools or recreation areas? How far away is the Lake Norfork Resort and what kind of facilities do they have?
Also, are there any interesting sites for tourists to visit in Mountain Home or the nearby area?
P.S.The lodging listed as Holiday Inn is now just the Baxter Inn, as they dropped their franchise.

Last year we stayed in Comfort Inn near the WalMart, it was nice and included a continental breakfast. The year before we stayed at Holiday Inn, were not impressed with that.
For places to eat, the chinese buffet place was good, the mexican place behind Comfort Inn was just ok.
The day after last year's competition one of our team members went up to Branson, MO. Got stuck in a big traffic jam there, too many tourists.
There seems to be lots of antique shops in the general area. There was one place the sold homemade beef jerkey that tasted really good, but that was a few miles away. Mountain Home is not a big place, but very friendly.
For things to do, if there's an Arkansas welcome station, you can probably pick up flyers there. I would also recommend a AAA tour book, if one of your team members is a member, you can get those for free.
We won't be back this year, Texas is finally having competitions. Won't miss the 12 hour drive but will miss the very nice competition that Arkansas puts together each year.
Anyway, if we were going back, I'd stay at Comfort Inn again.

Hi Les,
If a given team leaves something of their own (a container, a projectile, a barrier, etc.) out on their own side on purpose, it stays there.
All non-scoring items from the other field can be moved.
The referee from a given side can move mission models (deliverable, retrievable, and static) from her own side only, and only if:
1) Their own robot has touched the item
2) The referee will not be earning the team points
Hope this helps...
Take care,

Dear Mr. Evans,
The following rules clarification was posted in the Q&A section:
[11-18-02]
Q: If someone covers our market, can we ask the referee to remove it, by Rule 15? (the answer was yes...)
My question is what if team B covers their own (Team B's) market? The consequence being that team A cannot then complete the 8x12=96 point mission.
The way I interpret the [11-18-02] Q&A is that Team A can only request the referee to remove the object is if Team B covers Team A's market, but not if Team B covers Team B's market.
Thanks for the clarification in advance.

- Message by: Cleanup Crew 12/06/2002 17:18:31 GMT
Thanks for the clarification. That is kind of what I thought. I just didn't see any way that it would be possible for OUR referee to reach across to the other table and remove the cover. BUT since the rules were unclear and it is posted as a rule under Q&A and it is very clear in what it states, then we are going to work with that rule. I am instructing my kids to watch and ask referee to remove anyway based on the Q&A which is clearly stated. I still think they should have ruled against this tactic and I think they answered the Q&A question wrong!! Thanks again for forwarding their clarification.

Just an opinion, but it is going to be 40 degrees today with sunshine and there will be a lot of melting. It is only supposed to be down to 31 tonight so travel should not be a problem. I don't think there will be any postponement in a tournament this size at this point.

- Message by: B.O.B. 09/21/2002 23:56:06 GMT
All of the parts for the building the playing field would have come in a box with your team's registration kit that also included the team manual. Those started shipping in Aug in the order that teams registered. If your team ordered a mat, that would also be shipped to you. (highly recommend getting the mat, sure beats having to lay out the field with black tape like we had to do with the 2000 challenge).
The playing field pieces would be in addition to your Robolab or your LEGO Mindstorms kit. You don't build the playing field from your Mindstorms or Robolab kits, the playing field pieces were something custom chosen for the FLL challenge.
If you wanted to build a duplicate playing field, you probably could figure out most of the pieces from the instructions since they have pictures. But it would be hard to hunt them all down since there are so many pieces.

We also have an older Mindstorms set and the FLL set, and found that there are some differences. Mostly, a basic Mindstorms set won't have all the sensors that you can use, and some of the interesting little pieces aren't there. You could either start with you Mindstorms and add some additional kits and parts, or start with the FLL set.
- Message by: Eco-Nuts 10/01/2002 23:40:12 GMT
The FLL Robot set has some extra pieces. Other than that the sets are the same. There is information on this in the Q and A section for the registration. If you have a Mindstorms kit then you only need to buy the additional pieces for the FLL competition (extra motor, rotation sensor, etc). If you have multiple kits, then you only need to abide by the rules that limit the electrical parts that can be used.

Any other San Diego teams looking for a friendly competition? Maybe we can put something together. Kind of a bummer not to get into Legoland, especially since we are the "home team" and have so many parents that have annual passes there. Maybe next year they will hold two meets.
- Message by: B.O.B. 11/19/2002 08:14:27 GMT
Have any of you asked Legoland why the number of teams allowed is so low for their competition? That seems so strange that they only let 35 teams compete each year. Many of the other states hold bigger events. For example both Arkansas and Tennessee have twice as many teams compete each year. And the N Califoria State event allows for 60 teams.
We'll be going to one in Houston, Texas this year that allows up to 35 teams, but since it's a first time event, that's understandable.
Consider having those parents (as Legoland customers) write letters expressing that Legoland should consider opening it up for more teams for next year.

Discussion: "Consolation" tournament in San Francisco? By: SF-RATS 12/10/2002 19:33:06 GMT
We got a very slow start this year and I doubt we'll be ready in time for our local tournament (Dec 14). This means we are unlikely to qualify for the state tournament (Jan 12).
It's really not that important to us whether we get to the state tournament or not, but it would be fun to have some kind of tournament in January, even a very small one, so we can at least try to work on the challenge a bit longer.
Is anyone else in or around San Francisco interested in this idea?

There is also a Holiday Robot Expo at Fort Mason on the 15th if anyone is interested. We are going to be there with our FLL team showing our stuff, ready or not.

The information I have heard is that cameras with IR focusing can mess-up the programs on the RCX. What are teams doing about that?
Discussion: Should teams be encouraged to cover the IR porton the RCX with Duct tape? By: C&W Urban Knights 12/14/2002 20:28:20 GMT
- Message by: TeknoDevils 11/25/2002 16:39:25 GMT
Teams should not be encouraged to cover the IR port with tape since it is against the rules.
Some tourney directors have made house rules that allow the port to be covered. Check
your tournament specific rules.
A word of warning. What looks opaque to human eyes can be very transparent to IR light.
Black electricians tape is one such material. It may as well be made of clear glass!
Of course you can (and should?) cover the port with LEGO.

- Message by: C&W Urban Knights 11/26/2002 14:40:22 GMT
We were encouraged to cover the IR port at a local tournament. I think perhaps our IR tower at home messed up the sensor on my camera. Others report messed up programs on robots from picture taking at tournaments. I hadn't seen anyone else on the forum mentioning it this year and wanted to give folks the heads-up.

Our tournament director in Maine announced that covering the IR port with masking tape was the only variation from the official FLL rules. I didn't see anyone bothering, though. We didn't...
What was repeatedly mentioned was that, during the actual competition heats, flashes and cameras that used IR for focusing should not be used.
- Message by: Roboscorps 12/12/2002 22:22:26 GMT
A few years ago, our robot was accidentally reprogrammed by another team just before competition. After that, our students did experiments trying to find out what material would prevent this. They were most successful with aluminum foil. So now, they have foil lined boxes that they store and carry their robot in.

Interesting!
Last year we went to Maine, and the rules prohibited tape on the IR port. I
remember at least one 'hit' from a camera at competition. All things change!
Of course, you can build a shield from LEGO to cover the port. Or, if you are like
my builders, you can hardly find the RCX let alone try to program it or (heaven
forbid) try to change the batteries, so who needs a cover!
At a local competition I helped to run last year, we allowed tape. The 'funny' thing
was that we discovered that black electrician's tape is transparent to IR! Yes, we
learned the hard way. The program and firmware was trashed from an excited parent.
Duct tape with its metal film seems to do a good job even if it does leave a sticky
mess behind.

I've verified that my video camera (Sony) will interfere with the robot during operation. The robot will get "confused" at certain points in the programs, especially when line following.
I ran tests at our practice table. The robot would not work correctly while being filmed but worked fine the next cycle after I shut off the video camera. I did not check the flash problem but that is pretty obvious at a competition. Video recording is not obvious unless your looking real close around the tables (and above!).
At one competition I saw the symtoms of interference during one of our rounds, but that was before I did the test....
If the V cameras are on manual focus they "shouldn't" cause interference, but that is hard to verify. I'd like to see a ban on all filming in the competition area. Another note to be aware of: many of the new small digital cameras are capable of video recording!!!!
My request is If you NEED to record the robot in action, do it at the practice tables.
Also leave the RCX remote control at home, I've seen these at some pit tables!

Glad to be involved!
- Message by: FIRST Knights 09/17/2002 00:28:46 GMT
We are a small Catholic School in North Charleston, SC. We started last year and did very well in the state competition. I can't say what is best to do, only what worked for us.
First: Make sure to get both a technical person and a teacher involved. (I think best is at least 3 adults to keep the kids moving. I tried doing it at first without significant teacher input and it was really tough. I'm the engineer and I don't know how to work well with the kids in a semi-school environment. My wife, the teacher, is telling me to say the technical person is more important. Bottom line; both are crucial.)
Second: Build all of the mission pieces so you know how big everything is.
Third: We had everyone study the points available.
Fourth: We tried to decide how many points we could get, with a good robot, then we worked from there.
Fifth: Traditional brain storming. I presented rules from the adult business world and worked on this. (The kids did not like this at all, but I think it was a major key to our success.)
Sixth: We split the kids up to start building the drive train, designing T-shirts, learn programming, working on the hypothesis. (I don't remember when we came up with a team name.)
Always: Preach and practice KISS: "Keep it simple, stupid." If you want to do well, a robust design is what is needed. If you want to have fun, due to limited adult talent, go for fun and don't worry about the points. If the robot and the program belongs to the kids, you will be winners! Everyone at the state competition who had the right attitude won!

I agree with the comments above. My experience from last year is that it's key to split the kids up into small groups. In large groups the kids won't stay focused. As mentioned above it's key to have help. In my view an assistant coach is required. Again working in small groups - divide and conquor.
I think it is also important to set the expectations with the kids. Have fun but also have the kids realize they are involved to learn about teamwork, robots, and programming. I also set the same expectation with parents.
As Steve mentioned above we had the kids brainstorm what missions they wanted to complete and describe in words how they plan to accomplish the mission. It's helpful to point out potential problems so the kids can resolve problems.
Once we built the base robot - again it needs to be robust we worked in smaller groups to program the missions we wanted to accomplish. This provides the kids with full access to the robot so they can iterate quickly on the program.
Changes in light and surface can alter the sensors, motors, etc. and hence how the robot responds. We worked on a hard carpet and then later switch to the competition board only the find out the robot respond differantly.
I live in Fort Collins so feel free to give a call if you have additional questions.
Hope the rambling helps!!

I am not a coach but I have some seggestions.
First, set up a schedual for times to work and have somebody bring a treat for every one every time.
Second, Adapt the programming and construction to other subjects. Such like hockey, a moving "stick", or maybe music, make a tune to go along with the robot when it is victorius! It also helps to alternate on the programming because for most of the kids it is fun for a short period thenn really really boring, most kids like to build(atleast in my former groups).
Also, to keep the kids interested have a break halfway through a long session to go play in the snow or play some sports.
Having more than one parent helps a lot! On my teams we had some highschool kids come in and help out. They also made fun by making a sort of yearbook of the team. You know, funny pictures, stories, and more. Make it fun by puting funny sayings on the pictures.
Last, don't jump in to fast. Get them interested with shorter sesions than gradually go to larger sections.
What age group do you have. Please don't think I'm kidding about these things. I started a few new, older teams at my new school and have lots of experience! Thank,

Thanks for the replies Everyone. Sorry for the delay responding. We're made up of mostly 5th graders from from Hanover Elementary in South Meriden, one 8th grader from Lincoln Middle, and one 6th and one 8th graders from Thomas Edison Magnet Middle in Meriden. Our two older teammates are getting some experience before moving up to the First Robotic Competition next year. Hopefully, for Team 228 "GUS" at Platt High School.
We were wondering if state tournament bids went to lottery last year or did everyone get in? There are currently 4-5 rookie teams starting up in Meriden and we were wondering if we'd need to have a city tournament to compete for any state tournament berths. I just checked the CT tournament and it only shows 39 teams with about 7 days to go. Does everyone wait until the last minute to register?
Being rookie teams is bad enough. If we need to put together a tournament too, that will really strain our resources. Oh well, I guess that's half the fun.

The rumor of a tournament in Meriden is not entirely true. I posted several question in the CT folder earlier. One of those postings had mentioned that we are all rookie teams in Meriden and we heard from some other veteran teams that the State tournament berths went out by lottery due to the number of teams trying to get into the tournament in previous years. So we coaches had agreed informally at a meeting, that we would pool any state tournament berths our teams received and would hold our own local tournament with the highest scoring teams getting to use the state tournament berths. This will only happen if, A) we get any tournament berths, B) not every Meriden team gets a berth. If we do hold a tournament, we may allow other teams in under the same rules. If you want to join the local tournament, your team automatically grants any tournament berths to the local tournament pool and may the best teams win. I am not the coach who was trying to organize this tournament, but I can certainly bring any requested to his attention. Like I said in that previous posting, as rookie teams and coaches we already have enough on our plates. Organizing a local tournament is a lot of work if we don't need it to advance to the state tournament. Please note, we would love to hold a fun / informational tournament in the spring after the state tournament. We really want to get other schools and groups to form teams in this area. The more the merrier. Good Luck Everyone.

The Old Greenwich School City Sabres and Lego Freaks are planning on hosting a tournament on either 12/12, 12/13 or 12/14. This will be a FUN and INFORMAL tournament (team coaches will act as judges if necessary). We will only have enough time for a robotic competition (around 4 hours - including time for pizza) - no team research presentations. Both of our teams are made up of fourth and fifth graders, so we would prefer (although not absolutely) that we compete with the same age group. While we are putting together the logistics, if you are interested, please respond to the 2 e-mail addresses below, with your team name, availability for 12/12, 12/13 (either of these nights would be from 5:00 to 9:00) 12/14 (8:00 to 12:00) and your ability to provide a table. We will look to take the first 8 teams that respond - the tournament will be in 2 or 3 rounds, but each team would have at least 4 matches.
The location is being finalized (there remains a chance that the location falls through, but we remain confident). Our goal is to firm-up location and participants over the next several days.

Would like to hear from FLL teams from Meriden, Wallingford and Southington. Thinking about submitting information to the Record Journal reqarding the FLL concept and or tournment. I am the coach of Lords of the legos, would like to hear from other coaches regarding their teams, team names, how many kids, where the team has been meeting, how many helpers, etc. I do not work for the paper but thought it would make sense to try and get some information in, perhaps in the Monday home town page.

Discussion: Modular Housing By: Urban Chaos 11/08/2002 01:18:47 GMT
For the modular housing that are kept in the base, is there a specific place they must start in? We are unsure of whether or not we can position them where we want or not, to finish our programming.
- Message by: Eco-Nuts 10/29/2002 16:52:25 GMT
You can move the deliverables and your robot while it is in the base. The only rule is that the robot and it's deliverable must start totally inside the base.

Discussion: things that can be elevated By: Urban Chaos 11/08/2002 01:17:22 GMT
In the competition, for things that can be elevated (such as modular housing, bundles, and food loops) can we bring them back to the base, stack if needed, and put them anywhere on the robot and then put them on the appropriate spot on the board? (with the robot)
- Message by: larri 3000 11/04/2002 00:14:25 GMT
Yes, anything that is retrieved back to base can be handled (stacked, loaded, etc) manually. Then the robot can be sent back out to deliver the objects. Check elsewhere in the forum for more info. To have an object get back to base some part of the object must pass the plane of the base. If the object doesn't make it back to base it will likely be removed by the judge.

No, you don't need to use any sensors if you don't want to. Based on our testing they sure can help if your planning on navigating by dead reckoning. All the robot designs we tested had drift, and other errors that seemed to change between runs. Very hard to get any decent success rate. But maybe you've got a great robot design. Good luck.
- Message by: larri 3000 11/13/2002 01:25:41 GMT
The time limit set by the rules is three minutes for your presentation. I haven't read the tournament rule package yet for the CT tournament. (it was just emailed to me) Some tournaments have a seperate room set aside where your team goes before the judges. (I don't think there are audiences in this style set up. Other tournaments have the judges move around from table to table in the pit area and conduct the research project there. Check your tournament package or contact the tournament coordinator listed on the tournament page. And finally, yes the research project is definately presented at any state tournament. Good Luck.

Two orientation questions for the playing field:
1) Is the raised bridge deck to be lowered on the part of the bridge that is farther away from base? It looks this way from the pictures, but confirmation would be wonderful.
2) Is the lever at the bottom of the hinged platform supporting the toxic barrels closer to the river or the windmill?
I don't have my playing field right with me as I ask this --it's at school. Perhaps the orientation may be marked on the mat, so I apologize if the answer is printed on the mat.

Playing field and table.
I made the table as outlined in the manual. The playing mat is too large for the table as outlined in the manual. In the directions it is 45 I 93 inches but the mat is larger. I assume you don't cut the mat and need to change the dimensions. Is this correct?
David
- Message by: SharonA 09/23/2002 04:15:18 GMT
The table is really a 4x8 foot panel. With 2x4 borders, which are nominally 1.5 inches thick, subtract 3 inches from 48 x 96 and you get 45 x 93. That is where the dimensions come from. This *IS* the size of the table, plus or minus a quarter of an inch, at a tournament.
So the bottom line is, if the mat is too big, just place the borders over it. If your borders are already attached, you should cut the mat.
The question is, where to cut from? I think you need to inspect it, to see where 3M might have slipped up, but generally you want the Base area to be right up next to the wall on two sides.
As Referee, I have been involved in cutting down mats at tournaments. It definitely happens. We don't grow tables at tournaments.
It is a VERY good idea to try to practice on several tables. They are all different, and you have to make the robots tolerate differences. This is very true of lighting, but also almost everything else.

We gave the mission planning sheets to the kids to work out the sequence of events on. We then had them "pseudo-code" directly on the sheets before trying to actually program the 'bot. Things like "right-hand wall follow until black line", "lift arm up", "turn around", ...

- Message by: Eco-Nuts 10/07/2002 18:30:16 GMT
Some teams use the light sensor to sense the black border. Using other colors or no paint at all would not show up the same as the black border to the light sensor. If your team is not using the black border for sensing, then it should not matter. One other effect to the black border is to keep down the reflected light from the room. Black absorbs more of the light and does not reflect it down to the mat and change the light level on your light sensor used to sense lines on the mat. Again may or may not effect your robot.

Team Tiki,
Need more detail on your problem. However, the bridge is very solid and should not have any portion that when pressed it falls. It is intended to support the weight of a robot to cross the water. The instructions are not the easiest to follow but if you follow them closely it will produce a solid bridge.

- Message by: SharonA 09/27/2002 21:03:45 GMT
We had this problem. The problem is the long beams are attached at the SECOND hole at the hinge, not the first hole. This causes the deck squares to be off by one, and you get that unsupported center piece. Look at the outer hinge pin joints carefully and then at the instructions. You will have to completely rip the deck up. The lowest ramp deck pieces overhang by 4 studs.

Problem one is that the portion of the bridge that closes does not have the large gray blocks on it. Take the portion of the bridge that closes and lay it down flat ("road" side down). Look at the black construction pieces. This should look like the last page (14) in the Bridge_1of4.pdf. Page 10 of Bridge_2of4.pdf also shows a picture of the underside. Look carefully and this. Your bridge should look identical. Page 3 of Bridge_4of4.pdf shows the same for the other half of the bridge. these photos may help in the diagnosis of your problem.

You are not required to bring your table to the tournament. Many tournaments have a practice table as well as the tournament tables available. You may want additional practice for specific missions, this can be done with the mat and a portion of the 2x4 depending on how you use the wall. You can usually find a flat spot to place you mat on and practice as you need. I wouldn't recomend keeping is set up for long periods of time, but in emergencies is quite handy. Also most of the pits only give you a small table to use for your setup (not nearly big enough for the practice table).

LIRC: Having written last year's template, I have a couple of notes for this year.
1. There was more dual lock provided this year than last year in my kit. The two sheets I received were defiinitely bigger than last year's sheet.
2. Two dads did the cutting for me this year while I coached two teams instead of just one. They did spend some time being efficient with the cutting by matching up similar cuts. After they were done, I still had close to a half sheet left over.
I'm not sure if I still have what they drew up. If I come across that layout sheet in my stuff this weekend, I try to get it published. This is regional tournament weekend for my teams, so it won't be my highest priority.
Dave, you might want to consider a more universal file format, as Visio isn't all that universal for the community. I had the same problem last year publishing a *.wmf (Windows metafile) picture last year. At some point, I think I even faxed Marie Hopper a copy since her Macintosh couldn't handle either the *.wmf or MS Word document containing the layout.

They said I wasn't the only one who had some problem. Hey, the box says there are only 1308 pieces of which to keep track. Good luck to everyone on this building project. It helps to have a few LEGO maniacs around to decipher the diagrams.

Discussion: Suggestions on adhering playfield mat to competition table... By: Mindstorms Mayhem 11/08/2002 06:36:58 GMT
I am a rookie coach looking for suggestions on how to adhere the play field mat to the competition table. I learned from a veteran coach that the 2001 mats were prone to delaminate. This veteran coach also had trouble with adhering the 2001 mat to their table. Apparently double-sided tape peeled off in a day or two; spray contact cement didn't adhere for long either; trying industrial contact cement for counter laminates was real bad news, as the solvents attacked the plastic and made a real mess.
Does anybody have any suggestions for a way to adhere the 2002 mats to the table that avoid the above troubles? Is it sufficient to simply rest the mat on the table, or does it tend to want to roll back up or slide around when the robot is zooming about?
- Message by: TeknoDevils 09/19/2002 03:28:38 GMT
I am the veteran coach memtioned here! If you keep the table horizontal at all times you do not need to glue the mat down. In my case, I had to store the table on its side and had to glue the mat down.
This year I will simple staple the mat down along the edges and under the locations for the Dual Lock.

We did not attach our mat last year even though our table was also stored vertically. However, this year I have already re-rolled the mat (this means that the design is on the outside of the roll) so the ends of the mat will want to rest on the table rather than stick up.
Granted, living in a warm climate may have helped this problem.

Last year we used double sided carpet tape from Home Depot (ask for a donation !). It's very sticky and about 1.5 inches wide. We taped down the 4 ft. ends. The mat can be removed and re-applied without damage.
Note that double sided scotch tape does not work well.
- Message by: City Fire 09/20/2002 22:07:08 GMT
I can understand the reasoning behind holding it down if you are storing it vertically. But if you can leave it flat I agree with the others that nothing is required. The material, though curly when it is received will flatten out in a few days (warmth helps to speed this along) and should stay nice and flat through the season. Plastics don't like things stuck to them. The carpet tape is about the best you'll find for an adhesive to this material but be sure to remove it at end of season... it can leave it's adhesive behind. Nasty.
A note on Tables. I directed a tournament last year and found that several tables that came to the tournament were not built to specification. Not trying to be overly picky here but some of these robot programs are expecting walls to be within a certain number of 'ticks' away. The walls should be smooth because some robots butt up against and slide down them for accurate alignment during challenge runs. I suggest a bit of care in the construction of your tables.
Good times!

I agree with Jack Gregory of SharonA; there should be no need to tack it down. I built our table before we had the mat. Our kids would help me roll the mat out and then stow it at each session; in fact, toward the end they were doing all the setup and breakdown. There wasn't too much curl, and ours didn't delaminate, though it did get dented. This also meant our table is ready to use this year, with no glue or other adhesive remnants to remove or add bumps.

Well, yes, it's important to build your table carefully, but rough wood or other minor defects are par for the real-world course. The 'bot should be adaptible or the kids should be. The fact is that even the mats can end up with slight variations, so you have to go with the flow.
Obviously, your tournament may vary (ytmv). All the tables at ours looked good. But keep in mind that, while the rails are supposed to be "black", there are real spectral differences between flat black and gloss black and that in between. Then there's the fun of how overhead lighting might affect your team's 'bot...

The official FLL table plans call out the wall to wall inside distances are 93" and 45" with +/- 1/8". You should be able to count on that. If a tournament table is not in spec it will have to be remade to be within spec. The robot should be designed to tolerate this +/- 1/8" but need not have to tolerate more. The lighting is also trying to be standardized and overhead lighting should be kept to that in the plans again. However, lighting for cameras and other things sometimes interfere and unfortionatly you should try to build your robot to tolerate the differences in light by shielding the light sensor as much as possible. the black was specified as flat black 2 years ago but was not specified last year nor this year.
The mat is designed to fit under the round edges of the two by four so will stay down without any adhesive. We have coiled up our mat and stored it in the shipping tube. We never had a problem with curling.

There is simply no way a table is going to be rebuilt at a tournament. When I show up, I measure the tables, and try to correct what is correctable, but I strongly recommend not relying on a tolerance of +/- 1/8 over 8 feet of possibly warped 2x4.
Use the mat when you can. Use the walls as guides, but not precise positions.

Ours was shipped the same way with the same result. Heat helps somewhat (like a hair drier) but be careful not to get it too hot least it delaminate or melt. Heat and time got about half of the creases out but we still have the problem. I hope next time they return to shipping these in a tube!

I called Pitsco and they are supposed to be shipping a replacement. I'll update when I actually receive it. They said that all mats are being shipped in the cardboard boxes as they have no tubes this year. The customer service rep also let on that there was an unspecified quantity of mats which got damaged as a group (before shipment!), but in order to make the tight shipping schedule, they were sent out anyway in the hope that they would be okay. They did manage to reorder an additional supply in anticipation of complaints, so if they make good on their replacement promise, I'll be happy. At least we have all the Lego pieces so the kids can begin planning and testing with those.

Got the new mat yesterday - it's an improvement, but still has a few lines which I believe will eventually flatten out. Box had no obvious signs of crushing this time, but it's pretty obvious that next year they need to go back to tubes, even if it costs a little more.

I agree, they should go back to the tubes. Our mat was ok, but the box is not going to hold up as well over time as the tube from last year.
The material that the mats are made from is a bit on the fragile side and will "bubble" if bent. So it needs the extra protection of the tube for both shipping and storage purposes.
I also agree that the only way they will know there are problems is if people let them know. So if you did receive a damaged mat, by all means, say something to them.
- Message by: Eco-Nuts 09/25/2002 19:03:09 GMT
We also received a mat that had creases in it. The problem with the creases is that it delaminates and leaves "bubbles" in the playing field that may interfere with the operation of the robot. We called and were told that the mats were supposed to be shipped in tubes like most got last year. We received a second mat and again it was not shipped in a tube and received with creases and delaminations on it. So shipping has not corrected their problem yet. So yes everyone should call up and complain because this is unacceptable. The mats need to be shipped in protective tubes to avoid being crushed in shipping. I agree that they will not "fix" the problem unless they know that there is a problem.

Worked well and was strong enough to stand up to storage.
The only downside of this was when I had to move from

temp/humidity difference caused waves. I pulled up the
mat, let it relax and stabilize, then re-pushed it down.

Staples under the duolock works well and lets you store the table on its edge AND lets you leave some of the parts mounted. It isn't difficult to remove the staples at the end of the season. You do need a pretty good stapler, not a generic paper stapler open out flat.
Of course the bridge, windmill, construction site ... are pretty big and you may want to remove them when storing the table.

A CHALLENGING ROTATION SENSOR QUESTION: Is there a way to change the rotation sensor reading in the RCX without actually making rotations?
This would be useful if you wanted the robot to go backwards but not repeat a programmmed action. For instance, suppose you wanted to turn left at 60 (i.e. rotation sensor reading), continue forward and stop at 100, and then go backwards until 40. In this scenario, when you go backwards, the robot will make a turn at 60 but you want it to go straight until 40. If you could change the value in the RCX to, say, 200, after you stopped at 100, then you would back up straight to 40.
Alternatively, is there a way to program the RCX to ignore trying to turn at 60 on the way back?
I anyone knows if and how this could be done, I would love to hear from them.

Robotic Dolphins,
In short, one cannot reset the rotation sensor counts in RIS to anything other than 0. The rotation sensor can be reset to 0 using the "Reset Rotation" small block.
However, it sounds like you are using "Sensor Watchers" (the blue commands in RIS) to have actions initiated at certain times from the rotation sensor. The best way to avoid the problem you describe is to not use "Sensor Watchers" for checking your sensors, but to instead implement all the sensor interactions using the "Wait Until," "Repeat Until," or "Yes or No" constructs in RIS. In this way, the sensors are checked when you want them to be checked, and not all the time.
For more information on programming the rotation sensor in RIS, I would highly suggest that you take a look at the MN FLL "RIS 2.0 Software Training Lab." It is an excellent overview with lots of good tips on programming in RIS. The document can be found at the URLs below:

I have observed this behavior in RIS 2.0, and have heard it being a possibility in Robolab,
as well. I believe the fix would be rather than waiting for the rotation sensor to equal a
value, wait for it to be >= the value instead. I think what may be happening is that the
axle is spinning fast enough, that the code is not checking the sensor at the instant that it
is the exact value you are looking for.
For example, if you are waiting for the rotation sensor =100, change the wait to be for
when the rotation sensor >= 100 instead.

Need examples of rotation sensor with differential
Are there any examples of a base design that uses a rotation sensor attached to the differential. We just went to our 1st local competition last weekend and we need to redesign the base anyhow to increase speed and secure the RCX (which fell off several times during the matches). So I want the team to add a rotation sensor so we can use it instead of timing (which changes when you put fresh batteries in)

You can always attach a gear to one of the wheels and drive the rotation sensor from that gear. This will only let you know how much that wheel actually turned. As for securing the RCX, you can review the FIRST Scooter directions for ideas. the FIRST Scooter can be found in USFIRST.com / FLL / resources / coach tutorials.

Pitsco sells the worm gear housing, and there are several other sets that have it. You can also buy almost any part you need through BrickLink (www.bricklink.com), which is an incredible resource. However, you do have to know precisely what the part is called. For this, find a set it is in (in the case of the worm gear housing, use the Vision Command set), then go to Peeron (peeron.com) then find it as:
2 6588 Clear Technic Gearbox 2 x 4 x 3 & 1/3
And 6588 is what you can find it under in BrickLink stores.

Discussion: Missing Parts By: Street Dragons 10/23/2002 16:43:35 GMT
I understood that the competition kit had an extra motor and an angle sensor. These are on my package list but I can't find them. I have looked in the Mindstorms kit as well as the box that has the stuff to set up the table. I know what a motor looks like, but I may just be overlooking the angle sensor. Can someone help. I am not sure if this is the correct place to post this type question. If not, please tell me what to do.

If you have a "MINDSTORMS" set from a retail store, you only got 2 motors and no rotation (angle) sensor. If you got the PITSCO robot set, it comes with those (now). The table sets have nothing to do with the robot parts and should not be mixed.
It sounds like you need to buy another light sensor (to have two) a motor (to have three) and a rotation sensor (to have one). Those are the legal limits. All of these things can be had from PITSCO.

- Message by: Harris 09/25/2002 00:28:03 GMT
I believe so.
Quote from the rules:
13) DELIVERIES: When a mission involves the delivery of objects from Base to a location on the field, the team may load the objects onto the robot by hand in Base. The objects may also be delivered in a container made of LEGO elements, but in that case all rules and scoring criteria then apply to the container. Points for an object delivered are only awarded if the robot has completely let go of the object by the end of the match. Deliverables which remain with the robot when the robot is picked up will be given back to the team for future attempts.

In your case the container is the lego rubber band(s)!
- Message by: h3 09/25/2002 08:25:05 GMT
I too agree that the rules indicate you can use rubber bands to bind the bundles together - but I also interpret the rules to mean that you would only receive points for the single bundled bundle. Reducing your score by a factor of four, no matter how much easier it makes the bundles to deliver, does not sound like a good idea to me. Am I misinterpreting the rules?
- Message by: SharonA 09/25/2002 17:27:39 GMT
Yes, I think you are misinterpreting. What the rule means is that if a rule says the object must be completely inside something, then a containerized version of it must be completely inside. It doesn't mean a container of 4 bundles turns into one bundle.
As a referee, I will count a container of bundles as the number of bundles. But note that if your container spreads the bundles over some vertical space, then I would only count the lowest part of the container as the "level" for scoring. The entire container has to be at level 4 to be counted as 10 points per contained bundles. This isn't an issue with a big rubber band as the container, but it might be with other methods.
--Jack Gregory
- Message by: Harris 09/25/2002 22:15:20 GMT

Windows NT does not provide support for the USB port, and there are no free drivers available to solve this problem. For Windows NT users, this is also a problem when purchasing scanners or PDA's, many of which rely on USB only. There are a few 3rd-party companies which make USB drivers for Win-NT, but only for specific peripherals, not a Lego IR Tower. The only fix here is for you to use another Windows OS, or get a serial port IR tower. The latter is usually available cheap on eBay.

Here's two that relate for the updated Q&A section. It sounds like you would not be able to bring your own LEGO Houses already connected together from home. Am I reading this right?
[10-1-02]
Q: Containerization: Is it OK to pre-build a container holding our deliverable items from practice and bring them to the table?
A: You can pre-build a containment system, but the you won't be able to load it prior to setup because you must use the deliverables supplied by the tournamnet, and not your own.
[10-3-02]
Q: Can the housing units be connected together with LEGO pieces to make them easier to move out of base? The rules say something about using a LEGO-built container...but nothing about locking two parts together before moving them out of base.
A: It was not our intent to allow deliverables to be joined, but nothing written anywhere prohibits that, and so it will be allowed. Please use pieces that will come off in a hurry between matches, without ruining the deliverables.

One of my kids asked, "Why can't we make several different chassis custom made to the mission we want to accomplish?" Then we could snap the RCX onto the one we needed as needed. The idea is that the chassis is an "add on" whereas the "robot consists of just the RCX and the wires, sensors and
motors". The suggestion seems to fit the letter of the law. I told him it probably would not be allowed since what he was calling "add ons" might be considered the body of the robot. I thought this was a really clever strategy since his solution to the torque speed tradeoff was to have both with different chassis! Of course remounting the motors in a matter of seconds could prove troublesome. Maybe a swappable drive main drive train might be more realistic --- I presume that Would be considered an add on?
I am no longer surprised by some of the divergent thinking these kids engage in.

I believe this is legal. However, I think you underestimate the amount of "snapping" that would need to be done.

Any types of AA batteris can be used (you will need six of them). There are a lot of power differences between the life of different kinds of batteries. So it is very important that you understand the decay life of the batteries you are using. You would hate to have the batteries die immediately, or not fully recharge during a tournament. Be sure not to mix battery types (alkaline, rechargable, lithium, etc).
- Message by: Eco-Nuts 09/29/2002 05:43:16 GMT
It generally is not a good idea to use rechargable types at the competition. You do not get any warning when the rechargable types loose power. They die quickly. You should be aware that the battery power will affect the way your robots runs. If you time events, the motors will run slower with time and timed events might not be consistent.

Yes, voltage can be an issue with some rechargables. The Rayovac Alkaline rechargeable is good, as this battery delivers 1.5 V. The NiMh and NiCads deliver 1.2 volts, which is underpowered for the RCX.
I've been happy with the rechargeable alkalines I've used for two full seasons and the start of the third. I know that others wouldn't think of using a rechargable due to the possible issues with holding a charge reliably that are listed above.

- Message by: TeknoDevils 10/13/2002 16:39:01 GMT
Each motor receives almost the full battery voltage of
9 volts. There is a current limiting circuit inside the
RCX that prevents more than certain amount of current from
flowing to each motor.
Your consistancy problem is due to other effects. The voltage of alkalyn batteries stay very strong for about
10 minutes of use. The voltage than drops down and stays steady for a period of time before dropping down to nothing.
We discovered this last year when our magic numbers would have to be adjusted on a daily basis. A battery change would than require major changes. A solution is to get a mission to work once and then forget it. A few days before
competition, put in brand new batteries. Adjust your numbers but do not run RCX for more than 10 minutes. If need be, change the batteries again. Keep old batteries for meetings.
At competition, do not run more than a few rounds on the same set of batteries. This gets expensive, but it will be repeatable!

Lithium or nickel metal hydride batteries work nicely for

seven Mindstorm kits we have at our school. It saves greatly
in battery costs. But at competition will still use alkaline
batteries. For the first few minutes of their lives they are
better than any rechargable.

- Message by: TeknoDevils 10/20/2002 00:38:48 GMT
Marie,
By removing time, you dramaticaly improve your odometry
accuracy as batteries die. But you do not completely
remove the effect. At least two cases I have seen will
demonstrate other issues:
1) On a tracked robot, as power drops, the robot actually
was unable to turn.
2) Consider now the case of a fast wheeled robot doing a
pivit turn. With fresh batteries, the robot spins like mad.
Your code tells the motors to stop when past a certain
rotation count. Unfortunately, the RCX can only sample the
rotation sensor so often. So by the time it sees the tick
count exceed your value and then shuts down the motor a
finite amount of time and hence turn angle has passed. When
the batteries are low, the bot turns slower and the RCX has
a better chance to stop the turn closer to your tick value.
My approach to batteries can be found in my handbook at
http://home.attbi.com/~pssweeney/handbook.pdf
The idea is always to use fresh batteries when finalizing
magic numbers in your programs and at competition.

Marie,
The only accurate way to get a robot to move the same amount each time, independent of battery voltage is to use the rotation sensor. As always, the senosr is best used ahead of gear reduction as that gives the maximum resolution and more counts per traveled length since there are only 16 counts per revolution of the sensor.
Al
- Message by: Eco-Nuts 10/25/2002 21:40:31 GMT
Even using the rotation sensor will have some variability built in. Momentum of the robot will not allow it to stop instantly. The amount that you go past your desired rotation counts is dependent on how fast the robot is traveling and this is dependent on the voltage of the batteries. This variability is small compared with using time, but still is there and should be accounted for in your programming.

Discussion: Pneumatics pieces By: Legomen 11/28/2002 04:55:25 GMT
Can you use pneumatic pieces
- Message by: Catlin Gabel 10/01/2002 01:19:39 GMT
The rules this year say if it's made by Lego, you can use it. That being said, I'm not encouraging any of my teams to use pneumatics because it's hard to control them from the RCX. To get RCX control you'd end up using your last remaining motor (assuming you use two to navigate) to control a pneumatic valve. I haven't found too many things you can do with pneumatics that you can't do in a more straight forward way with motors.
You might be able to use pneumatics through some trigger that goes off when the robot runs into something, like a fancy spring. It could also trigger when you don't want it to.
A side issue is I don't think it's very good sportsmanship to use pieces like pneumatics that aren't readily available to every team. I think it will cause resentment at the competition if one of the top scoring teams uses pneumatics or some other obscure Lego technology to great strategic advantage. Never the less, the rules don't preclude it.

When words like SPORTSMANSHIP and FAIR are used, I assume people see FLL as a competition. Its better to emphasize that its about inspiring children with science and technology. If a team comes to the competition with a pneumatic enabled robot we should celebrate their achivement regardless of how they fair in the Robot Performance. The same should be true of a non-pneumatic robot. Remember we are learning the problem solving process.
- Message by: Catlin Gabel 10/03/2002 07:53:13 GMT
I agree that's how we should look at it... as a inspiring activity for kids to boost their interest in engineering. Unfortunately, those are adult concepts that many kids don't relate to. They see it as a contest, despite all our words to the contrary. If the contest seems "unfair" by middle school standards it could have the unintended consequence of kids deciding not to sign up next year.
Whether pneumatics crosses that line of being "unfair" I don't know. That will probably depend on how many high scoring teams use the technology to some great advantage.

Actually, there is something to pnuematics -- power. They have a very high thrust/weight ratio, and very high power*speed. And you don't have to use a motor to pump them, you can do that in base manually, and just have the motor trigger them. With two directions on the motor, it is very easy to get two actions with this method.
Not that I am recommending them to my kids, but don't be surprised or upset when you see them at a tournament.

First off, I have yet to see legs enter the completion, never mind see them preform well. Treads are good if you know how to use and gear them. Usually teams gear their treads down because treads treads have so much traction. However, it is possible to gear them for speed if your robot is light and in need of traction. Wheels are all around sweet juiciness. You can gear them for speed or power extremely quickly. Also the have moderate traction. But in response to your question do not, I repeat do not use legs. Deciding between wheels and treads depend on what type of robot you have.
- Message by: Atomic Minds 10/22/2002 23:31:51 GMT
We have found out the hard way that the big wheels are not a good idea when geared with a ratio of 1:1. We tested treads this year and found they are a lot slower, but a lot more accurate. As for legs, a biped is definitely not the way to go.Even with a four-legged robot, they are very unaccurate.
- Message by: TeknoDevils 10/23/2002 00:13:22 GMT
We used treads last year geared to the motors 1:1 using the 24 tooth gears.
Slow and power hungry. After just a few minutes we where having to change
batteries.
The other nastry problem with treads are their repeatability with turns. Turning
X rotation sensor ticks would cause varying turn angles. The issue is the
randomness of friction in a skid.
Our current favorite setup is 24 to 40 to the Mission Mars wheels and the odometer
on an 8 tooth gear of the 40 tooth wheel-gear. The Mission Mars wheels are nearly
the same size as the medium balloon wheels, but the tread is curved not flat accross.

AKA: treds cannot go up the bridge as easily (or maybe they don't go up at all) as wheels.
Treads go up the bridge just as easy or easier because of the huge ammount of traction. The only trick is that trads typically do not lift a robot very far off the ground making getting on the bridge more difficult. Treads are typically more all terrain and that is why they put treads not wheels on construction vehicles.
- Message by: cranium 11/19/2002 21:41:37 GMT
Some suggestions for using treads
We have fiddled around with treads a lot. For a while we had three different treaded robots and that allowed us to do lots of experimenting. Some of the things we learned;
- The treads are a little shorter than they should be if you use the standard 13-hole spacing. This gives them too much internal friction, in particular, by pulling to hard on the axles. To correct, grab the tread and stretch it HARD to make it a little longer. (If you think that violates the "no modified parts" rule then mount the tread on a 14-hole spacing, connect two motors, and run it a while. You may need to go to 15-hole spacing as well to get it to stretch.)
- New treads have a significant bias, that is, they are not evenly "bendable" along their entire length. This bias is probably caused by long term storage smashed flat in the box. In really bad cases, you can see the tread slow down every time the permanent bend in the tread goes around the drive wheels. The bias gives a treaded robot a jerky motion and adds a lot of inconsistent friction to the whole assembly. Stretching the treads will greatly reduce
this problem.
- New treads are kind of "sticky". Stickiness is very bad on a treaded vehicle since it turns by sliding the tread sideways and stickiness makes this difficult. To correct, take your robot out into your garage and run it around on the concrete floor for a while. Then wipe the treads off with a towel. This will pick up a light coat of dust and get rid of the stickiness. Your robot should now turn easier and faster.
- Since the treads turn by sliding one end of a tread sidways in one direction and the other end in the opposite direction, it helps a lot if the front-back center of mass is NOT centered over the tread. Move you robots center of mass to be 1/3 to 1/4 the way along the tread. Now when the robot turns, one end of the tread is carrying relatively little weight and will slide sideways much easier. The pivot point for the robot is usually very near the front-back center of mass. Moving the center of mass also moves the pivot point.
- Treads are very sensitive to bearing and axle friction. Don't make them to tight. For best results you should be able to just barely feel movement laterally on all axles, collars and bearings.
- If your robot won't track straight, check the side to side center of mass. Again, because tracks are so sensitive to axel and bearing friction, a robot that is heavier on one side will tend to turn in that direction. To correct, try to get the center of mass centered between the treads. (Of course, this also applies to wheeled robots.)

I don't like giving direct answers on the forum, because kids are supposed to arrive at their own conclusions.
Besides, advice this late in the season won't be usable until next year anyways!
The most important aspect of the robot is it's navigation abilities.
Since Lego parts and joints bend and flex, there is no way to navigate accurately enough to do all the missions successfully using only the robot.
What kids must determine is what else can be used to navigate successfully?
The black lines are one thing that can be used, but they can only tell the robot its position, not its direction.
A wall can also tell the robot its position, but not generally its direction.
The way to tell both position and direction is to bump (push) into a wall so the robot is zero degress (or 90 degrees) to the wall. Then the kids will know where the robot is, and its direction. Only then can the next leg of a mission proceed.
To be able to push into a wall, and have the robot "skid" to a 90 degree angle, think of what kind of wheel/tire/tread system is required.
There are not very many options that seem to work!
- Message by: Tobor 12/12/2002 04:13:11 GMT
There are other ways to accurately program, if used correctly the black lines are very useful in lining up the robot at a consistant point to proceed with a mission. Our robot used mostly black lines to align and was consistant around the 75%-85% range

The robot can return to base via its own power (as programmed by the team) as many times as the team wants during the 2 1/2 minute round without any penalty. The robot can also be retrieved manually by the team as many times as the team wants during the 2 1/2 minute round; however, the first four times that this is done in any given round, one of the "bonus food loops" which start out in your own market will be removed from the table by the referee, resulting in a loss of 4 points for the team each time a "bonus food loop" is removed.

Urban Knights,
It sounds like you have another program running that expects to use that serial port. Typically this would be a modem, fax in auto answer or mouse or like the example above, a Palm link that opens and runs whenever the computer is turned on. You can right click on the icons in the system tray (at the lower right of the screen adjacent to the clock) and they will tell you what program is running and give you options to turn it off. There is also the possibility that you school may be using a protection program that prevents students from accessing the ports without special access.
Hope this helps.

Actually our team is also having problems with IR transmitters. We have 2 1.0 Bricks and 1 2.0 Brick. We are using Robolab 2.5 on 3 separate computers. Also we have 2 Serial towers and 1 USB tower.
Our problem is that downloading among the various combinations has proven to be _very_ inconsistent! For example:
- If we download from the USB to the 2.0 Brick no problem.
- If we download from the USB to one of the 1.0 Bricks either it wants to download the firmware (and can't get past 2%) or it just gets part way through downloading and stops
- If we download fromt the Serial Tower to the 2.0 Brick the results are poor.
We are in a flourescent lighting room - so perhaps that has something to do with it.
Does anyone else have these problems? Any suggestions for minimizing the effect of the flourescent light (we've tried shielding them a little)? Is this something related to Robolab vs RIS?
Any help appreciated. Right now we're wasting a lot of good programming time dealing with these issues.

One thing that affects communications, independent of other factors, are the large number of Infrared devices now in use. Security cameras in schools use infrared lighting to "see" in the dark when classrooms are closed. Digital cameras and video cameras also use infrared rangefinding for focus, not to mention remote controls. All of these devices swamp the tower/RCX link and cause errors or failure to handshake. The garage concept above solves most problems and is recommended for competition.

You can but with some limitations. Using the differential the robot can go forward.
If you add a ratchet on one wheel to prevent it for turning backwards, when the
motor goes in reverse the bot will turn. This is the way cheap RC cars work. You
get forward and reverse with turn.
You can't get both forward, backwards, and left and right turns from one motor.

I am assuming the test is to place a gear on each motor and
see what motor 'walks' around the other?
This is certainly a good test. Please note that motors will
often behave differently going forward as backwards. A standard FLL bot is normaly symetric. This means to go forward, one motor is going clockwise the other counterclock. An advanced solution is test your motors
against each other when they are both going clockwise. Of
course you then have to build an unsymetric bot to account
for this!
After much experimentation we have found that the limited
slip clutch between the two drive motors can correct even
moderately unballanced motors. Also discarding a caster
and replacing it with a wheel or pulley without a tire gives great directional stability and yet can be overcome
for turning.
The ABSOLUTELY wonderful online book on building LEGO FLL
bots is a MUST to read, and then read again, and then read.
You would be even better to then read again!

Use gears. One way to provide large amounts of torque is to use the worm gear. The worm gear can not be driven backwards (when you stop the motor, the motion does not fall back down). Use any Lego peice that can hook up to an axle and provide a torque. There are several that have an axle hole on one side and a regular hole spaced out a ways. Use a gray or black connector to connect the regular hole to the side of your arm and let the axle act as the pivot point of the arm.

Few responded to your q because it is not in the spirit of FLL to give direct solutions!
The whole intent of FLL is have the kids design a solution set. The robot comes down to two components: The car navigation and the arm.
This year, the arm is a big challenge for all teams. It was meant to separate the serious competitors from the kids with toys.
If you ask a more secific q, such as "my kids built an arm, but it jams at the top because the studs hit the gear - how can we strengthen the mechanism" or such, people will be more willing to answer.
But to come right out and ask for a solution to the key difficulty - it doesn't seem like a good question.

Our first year we used 4 wheels and won the tournament. The next year we used 2 wheels and got a perfect score and tied for the win. So either will work. Our 4 wheel design was straight out of constructopedia where the both of the left wheels were driven by a motor and both of the right wheels were driven by a second motor. this produced a somthing similar to a tank drive without the treads. Turning required some slippage of the wheels and was less reliable than desired, but manageble. The second year we used the robot from the FLL training bot which is basically a three wheel system where the front wheel is actually the button piece and the left and right wheels are driven by seperate motors. This turns much more controlable as the button skids on the mat nicely. It will not work very well if you are trying to cross the bridge.
All missions can be accomplished by either type of drive along with lot's of other types of drives. The types of appendages used for each mission is the biggest factor. Think of what is needed for each mission. After that you can look for what modifications can be made to one thing to do another mission. Soon you will have only a few different devices to do all the missions. Now your challenge is to change from one device to the next when the robot returns to base and do all or some in the 2.5 minutes.

I think we agree. I said not to solve a mission. When someone is stuck on a problem we can help given detailed questions about the problem. A general solution should not be given to solve a mission as that is what the competition is all about. So, yes helping when people are stuck on a problem is great, helping to solve a mission is not OK. The original question was for a solution to a complete mission.

- Message by: Robocats 11/01/2002 19:29:23 GMT
I haven't seen any, but here's what we have been doing:
1. Get the robot to perform a simple task using the sensor, (i.e. turn in a complete circle using rotation sensor), then stop.
2. Measure the difference between starting and ending position.
3. Repeat the process 10 or 20 times.
4. Calculate the mean and standard deviation from the 10 or 20 repetitions.
5. Decide independently how much deviation from perfect is tolerable (upper and lower spec limits).
6. Calculate a Z-score, which is (mean - Speclimit) / standarddeviation.
7. Use the normal tables in any statistics book to determine what portion of the curve is outside (or inside)the spec limit.
8. Percent Reliability of the robot in that behavior is the total area under the curve between the two spec limits.
9. Probability of failure is 100% minus that value.
Most of the kids caught on easily to simple statistics, and it made it very clear to them how one method of performing a task is more reliable than another.

Tyres, tracks or legs???
Well all have their pros and cons.
On a slippery surface using four wheels we put tyres on the driving wheels but not on the front wheels. We found this helps steering as tyred front wheels grip but no tyres allow the front to slide.
Thacks were good to roll over holes in the playing surface (old challenge) and will probably survive comming off the edge of the bridge but turning is a lot more difficult and inconsistant.
Legs are nice, look cool and get great attention but are much more prone to falling apart. Turning is also less preictable as you have to slide 3 or more legs each turn.
These are just my thoughts, you should try all possibilities, that way you will get ideas on how to affect other problems. I ysed a leg as an anchor point once to assit a complex turn.
Have fun

supporting the weight of a robot should not pass through
just one beam. Look at this document:

- Message by: TeknoDevils 10/25/2002 14:49:06 GMT
Still not allowed. Dry powdered Teflon might not harm
the plastic, but would not be allowed.
Our "solution" is to clean the axle and its bearing hole
with a Q-tip and cloth using nothing but water. Getting rid
of old ground up plastic and other debris helps.
The true key is to properly desing the bearing. The wheel
should be as close to the bearing as possible. The bearing
should be not be just one beam wide. It should be two with
a space of two beams between.
Two beams side by side pinned together with black friction
pins appears to be a nice solution, but the holes do not
necessarily line up perfectly. This is the reason to
seperate the two beams.

5) ALLOWABLE PARTS: ... The robot must be built entirely from LEGO elements in original factory condition, without restriction on type or quantity except as follows:
--The robot may not contain any electrical parts other than: 1 RCX, 1 rotation sensor, 2 touch sensors, 2 light sensors, 3 motors, 1 lamp, and 6 wires.
--The robot may not contain any non-LEGO materials or substances such as stickers, tape, glue, oil, etc.
From the Q&A:
Q: The rule on allowable parts says we can use any LEGO, except for the electric exceptions, but can we use pneumatics, Star Wars, etc.?

Much like you would use a beep in your program to indicate whether the code actually got to a particular point, you could tell the light to light instead. The light is handy because once you turn it on, it stays on. Beeps just come and go.
One of my teams also used the light stacked on a motor, to tell when the motor was on. In this case, the motor was turned on only for a half second to work a latch so it was hard to tell while the robot was moving.
Both of these uses are pretty marginal in their benefit, but you asked!

My team has come across an old lego lamp piece that has two bulbs on top of one double thick 4x1 plate. The lamp is sensitive to the polarity of the circut. If it is connected one direction both lights are steady. If it is connected the other way the lamps alternate flashing on and off (right/left/right/left/etc). Is it considered to be one lamp because it is one indivisible lego part or is it two lamps because it has two bulbs?
For whatever it's worth, according to MLCad the part number is 4771.

- Message by: Eco-Nuts 10/30/2002 05:08:21 GMT
You can use the rotation sensor in multiple ways. One way is to reset the sensor prior to using it then place a repeat while/until rotation > x and place a follow line or move forward or turn, etc in the repeat. You will leave the loop once the rotation sensor is > x. The rotation sensor senses axle rotations. 16 counts per axle revolution. If you attach the sensor to a wheel the sensor will measure the distance the wheel has traveled. A direct connection to the wheel's axle will provide 1/16 of a revolution as the resolution of distance. If you run the rotation sensor with a gear you can get 1/x of a revolution for the resolution. You can reset the sensor before each time you want to measure distance or you can just accumulate the distance each time it is used.
Once you run a program with the rotation sensor used and run the program, you can then stop and use the view button on the RCX to view the value of the rotation sensor. You can press the view button to scroll through the I/O ports until the port connected to the rotation sensor is selected. You now can view the counts on the screen and push the robot from position a to position b and see how many counts will get you there. Now you can code that in your program and make minor adjustments from there.

Discussion: Rotation sensor seems to fluctuate its count By: StormLordsNC 11/21/2002 00:17:20 GMT
When we run a mission using the rotation sensor, we will get the count just right - lets say 40 gets us to the desired area. Then when we come back the next day or a few hours later and run the same program, 40 will go too far or not far enough. It misses the first target by a very significant amount.
This occurs when there are no changes to the robot or programming. Would battery drainage do this? Our thoughts were that no matter what the level of the battery - the rotations would be the same - it would take longer, but the rotations would eventually get counted, thus the robot would make it to the desired point. Does battery power affect the rotation sensor?
Thanks!
- Message by: TeknoDevils 11/05/2002 22:25:11 GMT
Battery power does effect distance when using the rotation sensor.
Assume you are driving at 60 MPH down the highway and slam on your brakes when
your odometer clicks over to some number. It will take you some distance to stop.
The same experiment at 5 MPH and you stop much sooner.
Same thing for the rotation sensor. It will only stop the motors after it sees the count
exceeded. It will then take some time for them to wind down to a stop.
You can minimize this problem by slowing down the robot (using a smaller power) in
advance of the count you want to stop at.
Another effect is happening as well. The RCX cannot watch your odometer all the time.
It has other jobs to do. A case can happen when you want to stop at count 500 and the
RCX looks and its only 499, so it goes off and does something and then comes back and
finds that the count is now 509. In another case, the count will be 491 and the next pass
will be 501. A certain amount of jitter is always going to be present.
What language are you using? In Robolab their are some tricks to minimize this issue.

There are, however, speeds at which rotation sensors become inaccurate, these speeds are given in a couple of Mindstorms publications, including Building Robots with LEGO Mindstorms and Building LEGO Robots for FIRST LEGO Leage, and the gist is basically that Steve Baker proved in an experiment that 50-300 rpm is a safe range to keep the rotation sensor from missing counts. However, between 14-50 rpm and 300-1400 the rotation sensors will DEFINITELY miss counts. So gear your rotation sensor up and down off your wheel or differential to run it within the safe range. Also, using dual differentials and braking, rather than coasting can help on cornering and keeping an accurate count.

Another possible help is to put a 0.1 second pause between steps to allow the rotation sensor to rest to zero. This tip appears in the MN FLL Robolab Programming guide. I had a team use this a few years back to help with robot control as well.
Some other thoughts: Have you been zeroing the rotation sensor? Are the zeroing and the counting both attached to the same port?

I would second the suggestion to pause between robot
actions. Go 150 forward. Stop. Wait 1/2 second. Turn
right 90. Stop. Wait 1/2 seconds...
The fact that without the pause the robot never truly
stops, makes the following action behave differently than
if done from a full stop. Inertia (a property of matter)
can be a real pain!
We wrote a library of subroutines this year and each one
terminates with a 1/2 second delay.

Thanks for those ideas from us, also. We had been stopping completely (braking) at the end of each step, resetting the rotation sensor, and continuing.... but hadn't thought to let it "rest" for half a second or so.
Yet another step toward accuracy. Thanks!

When you say "zeroing" do you mean resetting the rotation sensor? (RIS2.0 nomenclature vs. robolab??) Yes, when the program runs, the first step is to reset the rotation counter. However, I will have the members double-check their programs. Will also try the .5 second wait.

Michelle, I am showing my Robolab roots in my last post here. I believe it is called resetting the rotation sensor in RIS 2.0. With either system, you want the command where the RCX will change the rotation sensor count from its current value to zero.

We are having problems getting our robot to stop where we want it to. We have one robot that stops and turns when we want it to but we have another that will not. It has the big wheels on it and uses no gearing up or down on the rotation sensor. We tested its ability to stop by running a program to go forward at power 6 until R.S. > 80 which was approx. 3 feet when pushed by hand. Once R.S. hits 80, it was told to turn off motors by braking. When we run that program, it actually stops at 93 which happens to be about 7 inches past where it should be stopping. We changed the big wheels to the smaller balloon wheels and pushed the robot by hand the same distance as before and the R.S. had a reading of 127. When we run the program with these wheels, it actually stopped on 132 which was only about 1/2 inch past where it was supposed to stop. We would really like to use the bigger wheels to accomplish certain tasks. What can we do to help our stopping and turning? Would gearing the R.S. so that it has more counts help? Or do we just run each segment of our program and adjust our numbers so that it actually stops where we need it to? Would it help in our mission if we reset the R.S. after every stop and/or turn? We also wondered if the speed of our forward motion was too fast. Would it help if we ran full speed on a long run, but then slowed power way down about 10 to 15 clicks before we wanted to stop. Please help!!

WOW, Your message is not simple to answer!
When you went to smaller wheels, you did two things.
1) You slowed the robot down
2) You increased the # ticks for a given distance.
As I mentioned in the post before, slaming on the
brakes going mach 3 will have to coast some distance (7")
before you can kill all the momentum you have built up.
Going slow prevents this problem.
Increasing the ticks per wheel rotation is also good. You
can get better accuracy IF you can stop at the right tick
count.
So as in the real world, you have a compromise! Do you want
to go fast and not be as accurate or slow and precise?
Going fast, you can help yourself if you slow down in
advance of your final count. Figure out how many ticks it
takes to come to a halt by coasting the motors. Subtract that magic number from your final number and drop to
power level 1 when you get there. Then brake stop at your final count.
Gearing up the RS will help only if you can stop the robot
at the count you want! Solve this issue first.
What language are you using? If you are using Robolab, be
advised that the WaitFor Rotation icons have a NASTY NASTY
1/100 second delay loop inside. You are MUCH MUCH MUCH MUCH
better of coding a polling loop with a RS > or < loop
yourself. Not sure about RIS.

Another interesting exercise I have given some of my teams is to ask them to create a calibration curve for the rotation sensor. Steps:
1) Get a measurement reference point for measuring how far the robot travels. A square front edge of the robot is good.
2) Find out how far the robot goes for 100 clicks, 200 clicks, 300 clicks, etc. Change the number of clicks in the test program as appropriate for your robot. I recommend making measurements in millimeters, as my 5th and 6th graders don't always get fractions well enough to operate in inches.
3) If your kids are patient enough, have them retest levels for repeatability of distance.
4) Create an x-y graph of clicks versus distance. Higher level teams might even be able to handle curve fitting and x-y regression on a spreadsheet.
Not only do you then have some ability to predict your robot's performance with the rotation sensor, but then you also have a tool to translate distance for a mission to setting the number of rotation clicks right in one or two passes!
A slow robot is predictably linear in response with the line running through zero.
A fast robot (think 1:1 gear ratio with balloon tires) ultimately has a linear response for longer distances, but the calibration line may not run through the origin due to the overcounting issues described above. I've not tried Skye's Robolab suggestion in post 5.1 to move away from the "Wait for Rotation" command, but this may also change the calibration curve.
There is extra credit for the teams with dual differential drive robots who use a variation of this technique to calibrate their turns! ;-) Dual differential drive = motor A drives left wheel, motor C drives right wheel.
You'll have to experiment with the rotation sensor resets at each change of direction, although I usually recommend them.

Be careful slowing down a robot! It sounds good in theory, but in practice there are problems.
Slowing down to speed "1" (or even 2 or 3) can cause the robot to stop early, and it will never reach its target rotations! This can result in a lost mission and lots of lost points, especially under a heavier load such as the houses.
Going from top speed to zero seems to be very accurate if the RS is geared up from the drive wheel AND the motors are stopped with brakes! Yes it will coast a bit, but the coasting is repeatable and not variable.
The coasting problem seems to be more a function of the drive train power. When using a single motor with a differential (weakest power possible), the coasting causes severe randomness in the distance travelled.
When using a motor on each side with no gears, the coasting causes substantial randomness.
When using a motor with an "8" gear on its output shaft and a 40 tooth gear on the wheel (like the Roverbot), then coasting is not random at all (when going from top power to off with brake)!
- Message by: TeknoDevils 11/21/2002 00:17:20 GMT
Your points are well placed. Yes, you can shoot yourself if you coast to a stop before
your final tick count. But, you can also have problems if slam on the brakes too late.
The point to understand is that the dynamics of each bot will be unique. What is good for
a tracked robot going at a snails pace will be very wrong for the robot using the big balloons
and no gear reduction.
The other issue that forces our team to slow down before a stop is that we will actually
loose tracking and SKID accross the mat! Not that we are traveling that fast, but the wheels
we are using have little friction surface. We are also forced to slow start for the same reason.

With the bigger wheels your robot will be going faster, thus have more momentum. Just like with a car, the faster you go the longer it takes to stop.
What do you do in a car when you need to stop accurately?
What would you think of a driver that went the speed limit until they hit the intersection at a red light and then slammed on the brakes?

Discussion: Extremely strange error message By: StormLordsNC 12/09/2002 08:27:35 GMT
I hope I can describe this problem coherently..here goes.
One of our team members was "tweaking" his program and saved it to the pc and downloaded to the RCX. Then went back to add a beep at the very beginning. He was unable to add any blocks to the program - they just wouldn't "drop" into place (RIS). So, he saved what he had, again. An hour later he somehow saved his file into a new file and downloaded to the RCX (he was able to "drop" blocks into the program). The team then started going through their missions. We tried to download each of the 4 mission programs into the RCX and received the error message "Unrecognizable brick error." For the next hour we went through 3 IR towers, rebooted the pc, changed to another pc, changed the batteries in 3 RCX's, reinstalled the firmware in 3 different RCX's. Nothing seemed to work. I finally had to uninstall and reinstall Mindstorms. I then opened a program from the Mindstorms vault and was able to download to the RCX. However, I was not able to download the mission file from the mission that gave us problems. However, I was now able to download all the other missions that were giving us the error message.
Has anyone ever experienced such craziness or this error message? We were beyond frustration - esp. when we changed pc's and tried 3 different RCX's and reinstalled firmware.
Sure do hope this doesn't happen during competition!

We have had problems similar to this. We are assuming the program file somehow is corrupted -- because I copied the file to another computer and it wouldn't allow itself to be changed or downloaded from that machine either. Couldn't put in blocks or anything. Couldn't download to RCX. Also switched towers, etc.
Then I did a "save as" and renamed the file, forcing it to rewrite the data. Then the program (the "saved as" new copy) worked fine. The original file was still unusable. So now when we run into this problem (infrequent, but incredibly frustrating), we rename the file and discard the old copy. It seems to fix it pretty reliably.
Someone else may have a better solution, but my theory is that RIS sometimes corrupts something in the file and forcing it to re-write the program data to a new file corrects the problem (rather like working with a Word file that has been corrupted).
This problem seems to have nothing to do with what the students are doing; it is intermittent and arbitrary (although it does seem to happen with the more complicated programs). But if it were an error on the students' part, it would not be logical that simply doing a "save as" to rewrite the data would correct it.

For a surefire way to fix the problem always save to the hardrive and a floppy disk. Save to the floppy disk only every two or three times it's saved to the hardrive to make sure the program is not corrupt when saved to the floppy. Then when it fails just load from the floppy. Very cumbersome and repetitive but worth it.

We do back up to floppy and tried to "restore" from the floppy to the hard disk. Then tried to download to the RCX and continued to receive the "unrecognized brick error".
My theory, for what it is worth, is that the corrupt file, corrupted the Mindstorms software (perhaps the IR driver files or RCX driver files) which in turn corruped the firmware in the RCX. Therefore, no matter what we did to put a "clean" version of the corrupt program on, we continue to receive the error message. I believe it was corrupting drivers because we switched to 3 different towers and 3 RCX's using 2 different backups of the same program and still received the error. Not until we uninstalled and reinstalled Mindstorms, thus reloading the firmware on the RCX, were we able to download any program to the RCX.
A very strange thing which I will have a better idea how to handle next time around - lets just hope it doesn't happen during a big round!!!

Our problem with the file not allowing bricks to be dropped and also giving us the "brick error" message was corrected simply by doing the "save as." We had changed computers, RCXs, towers, etc., moving the file between computers. It wasn't until we forced RIS to re-write the file with a "save as" and ignored the corrupted version, that we had any success saving it.
I'm just wondering how many bugs RIS has, as you obviously hit one more severe than the one that bit us. We've also run into the being forced to rename Big Blocks problem. As soon as I have time (HAH!!!), I'm going to evaluate RoboLab and am considering changing to it as soon as this challenge season is over.

We have run into rename Big Blocks problem. Hmmm, wonder if our file corruption problem had to do with that. The programmer of this particular file loves programming and creating his own blocks - thus, had several of his own blocks in this file. Earlier in the day he hit an "endless loop" - RIS kept prompting him to rename a block and he hadn't made any changes that would require such an action.
We are keeping our fingers crossed til the end of the season and will have to ponder Robolab, as well.

NQC software is not legal for FLL competition. If you want a text-based language, your only choice is Mindscript. It's what we are using because it's the closest to "real world" programming of the three legal environments. However it has it's own set of undocumented bugs. I think there's a section in this forum somewhere about Mindscript. I'm willing to discuss the problems we've found and how we've gotten around them, but I get the feeling hardly anyone is using Mindscript directly. When something doesn't work you have to think about it from the compiler's point of view and get a feeling for the kinds of things that are just downright broken. This sounds a lot harder than it is. From the kids' point of view, I just tell them certain things aren't allowed, like mathematical expressions. You have to build up everything from =, +=, -=, *=, and /=. Maybe a little ugly, but not such bad training in the end.

If yours isn't working at all, have you installed the tower drivers manually? If not, go to the RoboLab 2.5 CD and into the Tower subdirectory. Run Tower.exe.
Also, just for the sake of doing everything possible, download and install RoboLab Service Pack 1 from the Tufts site: http://www.ceeo.tufts.edu/robolabatceeo/resources/

2. If our program has an error that Robolab does not see (in real-time or before download), the download will start and then stop, consistently, part way through. It will report an error with the USB, but it is really a programming error. This has happened on 2 different programs (both rather complex) with subtle errors.

- Message by: cranium 12/09/2002 00:35:30 GMT
WRONG!!!!!
I'm not taking about the IR tower. The RCX has its own (internal) IR transmitter and receiver. The RCX can "ping" with its IR transmitter (NOT THE IR TOWER), and receive its own message on its IR reciever when it bounces off an object.
This has nothing to do with downloading or the IR tower. Since it is an integral part of the RCX it IS allowed by the rules.
- Message by: Mindstorms Mayhem 12/09/2002 00:43:12 GMT
Tobor,
Actually, I do not think that the strategy referenced by cranium is forbidden, at least I
have never seen a rule to that effect. The IR to which cranium is referring is not the
Serial Port IR tower or USB IR tower that you connect to your computer to program the
robot, but is the IR transmitter that is within the RCX itself. This transmitter is not
generally used for anything but programming. (During programming, the IR communication
between the computer IR tower and the RCX is not unidirectional, but involves information
being sent both ways, from the tower to the RCX, and vice versa.)
However, within Robolab, there are functions that can be used for sending messages
using the RCX IR capability. These are intended to allow communication between
multiple RCXs for really advanced robots with multiple RCXs. However, these functions
can be used to turn the RCX IR transmitter on, and then use the light sensor to look
for the reflections off nearby objects. The intensity of these reflections can be used
as a crude proximity sensor.
That said, yes, it is possible that a team turning on the IR transmitter in the RCX
could affect the programming of the other team's RCX! I do not think that such
activity is forbidden by the rules, but any sort of usage of the RCX IR transmitter
with a hostile intent (such as intentionally interfering with the other robot's programming)
is VERY CLEARLY against the spirit of the FLL competition, and would surely be viewed
very unfavorably by the judges.
However, experimentation with the use of the IR transmitter in the RCX as a
proximity sensor would be a really interesting activity for an advanced FLL team
in the off-season.

Just to add to Ken's great answer.
Using the internal IR transmitter to send messages would
not effect the other robot unless:
1) They are using IR ranging as well.
2) Someplace in their program they are waiting for a
message from another RCX. VERY unlikely.
The reason is that the IR is modulated in a way that the
RCX is expecting. An IR source from a camera is not of the
right format and can confuse, even render an RCX unconsious.
Just remember, your milage may vary...
PS. I have performed this experiment and have found it to
be lacking when looking for the table border. As it is flat
black, it does not reflect very much. I could only get results at a few inches away. It also varies dramaticaly based on the type of paint! It is also a huge drain on the
batteries. All in all not a solution we considered.

Discussion: RCX By: Alvin Technos 12/06/2002 18:12:38 GMT
why does the RCX always change to two when you download your missions? Couldn`t LEGO just leave what program is on the RCX L.C.D.?
- Message by: Harris 12/06/2002 18:12:38 GMT
The program slot the program is loaded into is specified in the 'Settings' menu for Lego's RIS software.
This also frustrates me. I would like to have the program slot be associated with the program itself, not the user. That way when you load a program into RIS and then download it it will use the same slot that was used the last time that program was downloaded.

Discussion: Wanted to Buy: 2002 City Sights Challenge Set or 2001 Arctic Impact Challenge Set By: Mindstorms Mayhem 12/13/2002 16:43:30 GMT
Hello,
I am looking to purchase a used 2002 City Sights Challenge Set, or a used 2001 Arctic Impact
Challenge Set. This was our first year of First Lego League, and the kids on the team are
eager to continue to do some robotics in the off season! One of the things that I am thinking
of doing is having our team split into sub-teams and possibly build robots for the 2001 Arctic
Impact Challenge, assuming that we can find a used challenge set from last year that I can
purchase.
Also, since we have two families on our team that built FLL tables in their basements, it would
be very helpful if we could purchase a used challenge set from this year in order to equip both
families with a table. Having two tables would also enable us to run "head-to-head" matches,
doing demos throughout the year ahead, or even holding our own little "mini-tournament."
If you have either a 2002 or 2001 FLL Challenge Set that you would be willing to sell, please
send email to me at "fll-coach@solidrocksolutions.com" Thanks!

The key word search only works if the team actually writes the word in their description or answers of the questions. We should encourage homeschoolers to say so. You must have not seen us because of the "ed" I tacked on the word on the team page. Besides is homeschool an accepted word or is it still home school? My computer spell checker didn't like it. Good luck finding what you want. Just now I had to override this to keep it compound.

Depends upon who you are talking to. Homeschool as one word is what most homeschoolers I know prefer. Spell checkers don't seem to know any better. I see it used as two words by the press and by those who use more structured curriculums. Those who lean towards more outside the box learning (which FLL is for sure), tend to use homeschool as one word.
I re-entered our data and now we do show up in the search. I had it in there before but it wasn't showing up. Now it works.
I agree, it would be nice to be able to find all the various homeschool teams doing FLL.

We are a rookie home school team from Charleston, WV. My biggest problem (so far) was getting a team together. We are part of a home schooling support group and I've been announcing FLL in our newsletter since March. I know I have had at least 2 teams and probably part of a third if you count those who signed up and then dropped out before the season started. (Can you believe home schoolers suffer from over-commitment?)
We meet every Saturday for about 4 hours and then give the members an assigment of some specific problem to work on during the week. Most of my team is 9 or 10 and in the 5th or 6th grade. You should have seen their faces when I started talking about gear ratios and putting math equations on the board.
I would like to hear about other home school team's problems and solutions to our unique situation. I wonder if we are getting enough interaction to really form a "team mentality" in just four hours of contact per week. To further complicate this, from what I have learned so far, it appears the teams need to be divided into programmers, builders and researchers. Any ideas on how to do this without splintering the team. A couple of our members have their own Mindstorms set so I was going to have them build a duplicate robot so the builders and programmers can still work together trying out different solutions on Saturdays but that seems to leave our researchers all alone. Any ideas on how to have the whole team familiar with everything for the tournament?

We had a good discussion last year on a related topic of teamwork which I think you would find helpful. The discussion went on tangents that give suggestions to some of your questions. Look under the archives folder: FLL International Forum\Archives\North America\Homeschool Teams\Teamwork.
If this is your team's first year, I suggest that you don't divide the team into separate functions until everyone gets some level of basic understanding in each area so they can find out what they're good at and what they liek to do. That being said, last year we got to a crunch point where we had to naturally assign functions because things weren't getting accomplished fast enough to be ready for the tournament. So it really depends on what your goal for the team is (see my comment last year).
Once we finalized our robot design, we built a duplicate robot so programming & testing could be done on both simultaneously and so we had a backup robot at the competition in case we dropped one! Fortunately we never needed the backup :)
One meeting a week is DEFINITELY not enough. Having a second meeting would go a long way toward helping build the team.

- Message by: B.O.B. 10/06/2002 04:21:16 GMT
I agree with Dana, having a second meeting per week would help with teamwork. I also wonder if the 4 hours is too long to meet in one stretch. If you have mainly 9-10 year olds, 4 hours is a long time for a meeting, even with breaks. We meet for 2 hours twice a week. We also throw in a snack, just to help with having a break.
I know what you mean about homeschoolers being over-committed, we generally have at least one or two families drop out for one reason or another.
We don't settle into roles for the team until we've been at it for at least a few meetings. And we let kids switch roles to different ones. After a few weeks, it settles into something natural.
The other question is are ALL the kids meeting for the entire 4 hours? I'd be tempted to have a joint time when everyone meets but then have 2 smaller groups before and after the main group meeting. For example, if maybe have half the group meets from 10am-11am, 11-11:30am show and tell/snacks, then have a joint meeting/session from 11:30am-1pm, then from 1pm-2pm, the other half of the group has some solo time.
Then sometime during the week have a shorter 60-90 minute meeting.
Just a thought, I'm just thinking of all that energy if it's a 4 hour stretch.

We are a rookie homeschool team from Dover, NH. I am planning on two meetings a week at about 1 1/2 to 2 hours each. But it seems the learning curve is pretty steep and I am wondering if this will be enough. For teamwork I am trying to build a sense of identity for the team, we selectively chose the name and are working on a team cheer. I am going to go look at those archives, (thanks for the info) and see what other ideas there are.

We meet twice a week for 2 hours. There is a learning curve, but we have parents who help so make sure to get them involved. So delegate some of your work out.
If any of your team kids are kits of their own, you can also have them do things at home, then share ideas at meetings.
The siblings of the team mates have been working on cheers for our team too and have some other ideas.

I should also add: We're doing our research portion outside of the regular meetings. The twice a week meetings are focused on the building/planning/programming. Otherwise, there just isn't enough time to get everything done.
For example, earlier in the week we met for a field trip in the morning before our regular meeting time, then had our normal meeting.

Howdy debugs!
This is the first year our state of Texas has an event for us to go to, even though FLL teams have been registering here since 1999.
For 2 years in road we had to drive for 12 hours to Arkansas to go to competition.
We're excited, ours is Dec 7th is Houston and they are also doing one on Jan 11 in Dallas.
There's several homeschool teams that will be at both events.
The Houston one also has an elementary simple machine competition going on at the same time as our competition.

may*hem - A state of violent disorder or riotous confusion; havoc
(The American Heritage Dictionary, 1982)
The meaning of mayhem is immediately obvious to anyone who witnesses the first attempt
at line-following on an FLL table full of mission models.

Thanks for expressing your appreciation of our team name. Throughout
most of the season, the team spent a LONG time grappling with the name
choice. The team brainstormed dozens and dozens of names. They even spent
the larger share of at least a couple meetings discussing names; indeed,
probably far too much time was spent on name choices when effort should have
been focused on learning first RIS, and then Robolab. It seems like discussing
names was on the agenda for every meeting, from our first meeting on the
night when the challenge was announced, through some time in November. But,
during that intervening period of writing their first programs, and having
the robot go off course again, and again, and again, while the team
tried different line-following algorithms, every time that the robot took
out the bushes, or the fruit trees, or the building site, or collided with
another robot trying to share the same table, sure enough, somebody on the
team would simply say "mayhem." Eventually, it stuck, and by the time the
team finally decided on a name some time in November, everybody could rally
behind the name "Mindstorms Mayhem" even if it wasn't their favorite choice.
And so, "Mindstorms Mayhem" they are, even though they are hoping that nobody
gets to see any mayhem from their robot at the state tournament. Only time will
tell.

Great, my understanding is that the winning team for Georgia was able able to get a perfect score in the finals.
Urban Argonauts had posted elsewhere on the forums they were able to score a 360.
That's very good considering that Georgia does their state event so much earlier than some other states (Nov 23rd). Ours is this coming Saturday Dec 7th and some state events aren't until January.
I assume you, the Street Dragons, are the other GA homeschool team. 6th is a good showing. Was this your first year in competition?

Hi Homeschoolers,
So far, there has been no news coverage. Information has been given to Atlanta Journal, Chattanooga Times Free Press and Georgia Tech's newletter. I don't know why this is not newsworthy.
We are the Urban Argonauts - we won the GA tournament with a perfect score. There were only 7 awards given out - no Director's award in this competition. The kids really tried for it and were strong in all areas. Maybe next year they will have more awards. We got the 1st Place Performance award. There was a Team Spirit award, Technical innovation award, 2nd & 3rd place performance and two awards for the research project.
Congratulations to all teams who participated! It was a rush at the end because our tournament was so early.
We hope to see other homeschool kudos here after the weekend.

Howdy from Texas, homeschoolers did well at the South Texas FLL State Competition on Dec 7th.
I believe there were 37 teams total in competition today at Texas's first ever FLL competition. We did 3 rounds, best score counted. Then the top 16 teams went into single elimination rounds until there was only one team left. For both the research and the robot design presentations each team did formal presentations to the judges in another room, then they narrowed them to 4 teams who did their presentations in front of the whole audience, then they picked the top 2 for both research and for robot design awards.
Our team BOB came in 2nd place on robot performance and won the Director's award. Go BOB Go!
We were in the finals for performance, robot design and research presentation. So although we didn't win 1st in any of those, I'm sure that since we made finals in all 3 catagories that helped our team in judging for the Director's award. Because we were among the 4 finalist for both research and for robot design, it meant in additition to doing the elimination rounds we also were up in front to the whole audience twice doing formal presentations.
2nd place Robot design went to homeschool team Urban Knights.
2nd place Research presentation was ARC, also a homeschool team. ARC did very well during the seeding rounds and was first going into the finals for performance. They were one of the few teams today that was able to get the barrels back to base. Our team had so many problems with rotation sensors that we had dropped that mission, but we did well enough in the single elimination rounds against whoever we were pitted against each time that we made it to 2nd place today.
The tournament director for the Jan 11th Dallas FLL competition was at today's event. (he's also a homeschooler) I spoke with him several times throughout the day. He said for his event there are quite a few homeschool teams registered but not that many public school teams. It's a smaller event (about 20 teams) but in a larger facility (we were cramped today). Our team has the option of also going to Dallas to compete (they had extra room and cleared it with FIRST), so BOB will decide next week or so if they want to go to Dallas as a competitor or if we'd like to just go watch. Most of our problems had to do with alignment and rotation sensors, with things that worked well at home but not at the event. We should be able to improve our score but we'll decide as a team if we want to take the time in preparation to get ready in January for another competition or not.
All I know is I'm very proud of how well the kids on our team did today, especially in their oral presentations. We had a great time and I'm sure it's something the families will all remember for a long time to come. And yes, the Director's award really does have an RCX built into it.
Other awards given out our event to various public and private school teams were Mentorship - given to to a group of high school kids, 2 judges awards, Sportsmanship, teamwork(1st place and runner up), 1st place performance, 1st place robot design, 1st place research.
No against all odds, no team spirit, no rookie team awards.

Hi all,
We competed in the PA tourny in Pit. on 7 Dec. We are a rookie team. We took the 3rd.place trophy in the research portion. There were 70 teams I believe. A home school team from the Philly area took top honors on challenge. 320 points!!( Robo Wizards). They also took another trophy but I don't recall. All in all I think homeschool teams won the most awards if I recall. I hope there is a offical listing some where. The kids had a great time. As a coach I am very proud of their accomplishment. When the pressure was on they rose to the occasion. Our robot performance was fair. We learned an awful lot. Look out next year!!!

Two teams of homeschoolers, "Mindstorms Mayhem" and "Mach 6", took the top two spots in a very close final match in the NH State Finals. Both teams had designed and programmed robots capable of attaining 360 point scores on their own. With the help of other teams, each team had also scored 360+ points in earlier rounds.

Congratulations. That's very good. Did your teams also do the research portion? Or did it just focus on the building/programming?
Our team had a lot of problems with rotation sensors so was never able to get the robot to do the toxic barrel mission correctly. As a matter of fact at the Houston FLL competition, I only saw one other team do that mission (another homeschool team ARC).
- Message by: Mindstorms Mayhem 12/19/2002 20:34:38 GMT
B.O.B.,
Thanks for the kudos! Our team also worked very hard on the research presentation, and came up with a pretty novel presentation which covered all the research done by the team as well as providing a bit of entertainment value. The research portion was excellent in its own right, receiving the 2nd place award at the NH state tournament (and a 2nd place award at a local competition the week prior.)
You are right that getting to the barrels required some of the most difficult programming, as well as a sufficiently compact robot to fit in that back corner. The kids used "landmark orientation" for almost all of their navigation, so the barrels mission was not too horribly difficult after they wrote a few line following algorithms. (I think our team spent approximately 14-16 hours of meetings on line following!) There were two other teams that had successful approaches for the barrels at the NH state competition. As far as I could tell, both used "odometry" for alignment. Their strategies seemed to work well, but they encountered some trouble returning to base, as the cumulative error made it hard to navigate back out of that far corner. We were fortunate with the line-following, as returning to the base was simply a matter of "follow the mellow black road..."

They mainly just like to build but she'd like to do more. She'd like to do the simple machines, but is concerned about picking kits that won't be either too advanced or too easy for the 7 year olds.
What's some good recommendations for kids in that age group? They really are not ready for programming yet with Robolab.

I highly recommend the simple machines kit. It can be as simple or as complex as you choose to make it. I would definitely also recommend the "workbook" that can also be ordered. We used one kit for 8 kids to save on costs. Then we created other kits from our other lego sets to have our own additional "kits." We did have to order a few specialty pieces but it still came out cheaper.

We also sold homemade spaghetti dinners in our neighborhoods, to our church staff, and to a few small offices for lunch and this was real successful. If you have a Sam's Wholesale Club nearby, you can get all the supplies you need, including tomato sauce, crushed tomatoes, Italian seasoning, hamberger, salad, dressing, to-go boxes, plastic flatware and napkins, etc. for about $1.00 per dinner. The parents made homemade rolls and pies. We sold a complete spaghetti dinner (spaghetti, roll, salad and pie) for $6.00 or $5.00 without the pie. It was alomost as fun and the kids were about as excited as working on the challenge.

We simply came up with a per team member fee based on actual and anticipated costs. Since we already had two tables built, this year was fairly reasonable. We charged $62 per child and the coaches' kids were not charged. Our families decided that this was really quite a deal - a weekly meeting lasting 3 to 5 hours (depending upon which team and coach) for 10 weeks. That's only $2 an hour for a great "class" and very cool experience!

Chickfila calendars. see my post over in the marketing folder. Those are an easy sell. We'll have enough to pay for team tshirts. Chickfila is very homeschool friendly and their coupons from the calendars are good anywhere.
We sell ad space on the back of our team tshirts to get sponsors. It's slow since there are so many other groups out there and since many have not heard of FLL. But we do a press release to explain it all.
The first year we did FLL we mainly paid for everything ourselves, but our money is tight this year, so we needed sponsors.
Grant info won't work for homeschool teams, we're not corporations or even a business. So sell space on your tshirts and talk to your local Chickfila about their youth group sales.

I think most grants would not be available to homeschoolers. Since homeschoolers are individuals and not non-profit agencies, that probably would make the paperwork harder.
We recently have been looking at Botball but were put off by the cost and by their statement about funding:
"KISS Institute believes that the most effective way to bring technology education to the general public is through the public school system. Therefore, first priority for general financial aid funding will typically be given to teams from public schools."
http://www.botball.org/registration/financialaid.html
That doesn't sound very friendly to this homeschooler.
Public schools get government funding. Homeschools do not. (although that brings up a whole other issue about strings usually be attached whenever government funding is involved.)

A word of caution about tshirts and sponsorships. Don't add a company to your tshirt until you have money in hand. We put in our tshirt order and had all our sponsor money in except for one company. They had said they would like to make the biggest contribution of any of our sponsors to our team. So based upon that, we made their logo the biggest of any of the other companies and sent in our order even though we had not been received their money yet. Long story short, but when it came time for them to write the check, they cut their contribution in half, and decided to give the other half to another robotics team (not an FLL team). We were very upset and still working out what to do. There were communication issues with some of our team members that contributed to the situation, it wasn't entirely the fault of the company that didn't come through as promised. But the bottom line is we need to figure out some solution that is fair to our other sponsors. The tshirts have already been done, so can't reverse that and we will wear them to an upcoming informal event. But one option we may do is do a second batch with a revised back cover that more accurately reflects how much each company actually gave and wear those to the state competition in Dec. We'll decide this week what to do.
Each year I learn more than the kids. This year my lesson was never again put in the final tshirt order until money is actually in our hands. Too many unexpected things can go wrong otherwise.

Transfers won't hold up as well as silk screen. Pick a colored tshirt and then do one color for your writing/design on your shirt. That's the cheapest way to go. You should be able to constrast it well so the design stands out without going to the added expense of using more than one color.
We got our shirts back today and they look great. We didn't use City Sights logo but wrote the words out. But we did use the FLL logo, which looked just fine in one color. We had our team name on the shirt with our artwork.
We also decided the sponsors looked ok as they were, it wasn't as bad as I thought it would be, the other sponsors can be seen just fine so we don't need to redo anything.
Anyway, I really do recommend silk screen. Our shirts from last year have been washed and worn many times but still look just fine. iron-on comes off over time to easily.
The Citysights logo in one color should still look ok.

How many of you find that teamwork is sometimes hard to build among homeschoolers? The biggest challenge seem to be getting strong personalities to work and listen to each other's ideas. The kids are smart and catch on quick but working together as a team takes more work.
What's worked and what has not for your team? We're trying some smaller meetings with just part of the team each time and see if that helps. When everyone is there at times it can be a bit of chaos.

We are really fighting on the teamwork issue. When we get them altogether, some are bossy, many are WAY too opinionated, some are shy, some just get left out. We've tried the whole class (17), the whole team (9 and 8) one at a time; we've tried groups of 4 and groups of 3. We've even gone so far as to try to have a member as a "team leader" to facilitate -- their idea of facilitating is telling others what to do, but doing mostly everything themselves and leaving the others out. They are not into delegation. They are not into listening to advice -- but they will pay attention if YOU build a robot with the ideas you are talking about and prove to them it works -- but forbid them to copy it in any way, if you do this -- make them look possible designs up in books. After these types of demos, we have found they usually decide that they will try whatever new idea (differential, rotation sensor) that they refused to listen to the logic for using.
This is our present solution (we'll see how it works in the long run -- it's been doing okay so far): We break them up to work in groups of 2 (4 per team) each brainstorming their own solutions. Each is assigned a robot and a computer. When they all have chassis solution, they get together as their team and test each other's solutions and vote on the best design.
Then each group has to build an identical chasis to the one chosen and test their arms and programs on that. Each group has to solve a number of missions; then they return to their team and all demo their solutions. Then the best armitures are chosen and those programs refined.
Then they have to start working with one robot per team and practice switching out arms, running missions in order, and practicing for the tournament (fast, fast, fast).
Of course, we are rookies and could be doing all this backwards!!!! But the demo part has really made a difference; we saw this proven for the first time at the World Space Congress when Team B.O.B., especially, the Bay Eagles, and some other teams made Artic Impact look easy. Our teams came back fired up to use rotation sensors (but still REFUSED to touch differentials, even though we explained their robot would NEVER go in a straight line without one). So we demoed the use of a differential in class, and they were converted. We would have them build more intermediate steps, but we are pressed for time.

Thanks for the input. I agree that most of the kids haven't had a lot of experience with teamwork, especially the younger ones. And you're right, kids don't know how to delegate at this age.
It's harder with a big group for everyone to be heard. The other thing is they will come up with many ideas and try different things, but it's hard for them to see the big picture and combine the best ideas together for a working overall plan.
Anyway, we'll see how the smaller meetings go, feeling the crunch time coming with our competition being just a few weeks away in Dec.

Susan, I was glad to see your post. We have 7 kids (6 of whom are hs'ed). Our problem is getting them to focus during a meeting. After they selected their roles and after about 6 initial meetings, we started rotating them in to work on their areas. When they all get together, it was a disaster - even if we had them lay out at the beginning what their individual goals were for the meeting - so they knew what they were supposed to be working on.
At this point, we are going to only meet in small groups to finish up any last minute programs they want to do and to complete the research project.
Dave, you seem to have LOTS of experience with FLL, can I emaily you personally for some advice on handling personalities?

Yes, This is my third year with the FLL. My first year we had 19 kids on one team. The second year we started with 22 kids on two teams. This year we have 10 kids on one team.

Focus is hard, especially when the whole group gets together. Some kids work very well in very small groups with only one or two other kids, but tend to get distracted in a larger group.
Goal setting is something that comes with experience and maturity. It's still an abstract concept for kids this age who tend to focus more on the here and now. And sometimes kids just have bad days and are not in the mood to work with others.
If one of the kids is a major distraction to the others on a particular day, refocus their energy and consider having them do something else during the time period that day. Maybe take pictures of the team at work, help design a banner, help put together the team notebook or even have them go look on the forums during the meeting time to see if there's any good updates.
One thing that we try to do is gather everyone together for a few minutes at both the start and the end of each meeting and have each person say what their status is. That helps the quieter ones get a chance to be heard and gives the whole group an idea of how things are progressing in each area. We're trying to encourage the team to email each other and the group between meetings but some are more likely to that than others.
Go ahead and do the small group meetings but you also need to do at least of couple of big group meetings when things are closer to being done so that everyone on the team knows what each subgroup has done. The big meetings might be easier once the missions and research are closer to completition. Prior to competition all the team members need to have at least heard what the overall results were, even for the parts they were not directly involved with.
We also do lots of testing of the programs towards the end, that just requires part of the team. Prior to competition you'll want to test and retest the robot's program over and over again to make sure it performs the same each time. Then when your robot seems to be testing pretty good, those kids can do some test runs in front of the whole group.
It's going to be easier overall on the team if the team decided in advance who the 2 operators at the table will be and who will be the primary speakers for the reseach presentation. Let the kids practice speaking, you can have the parents pretend to be the judges, listen and ask questions.
One of the things that does happen in competitions is that throughout the day various judges and officials will ask kids on your team what they did, what they liked, ect. So it's good if everyone on the team knows what all the team did. Sometimes it's just someone stopping by your table for a few minutes, other times it's more formal, with them taking notes on what the kids say.

How are the locations for the state tournements determined? What can we do to have a state tounement in our state?
- Message by: City Fire 09/19/2002 04:11:19 GMT
All FLL tournaments are run by volunteers. State tournaments tend to be sponsored by business(s), universities, or larger organizations. Local tournaments tend to be smaller events working on much smaller budgets though they can be as large as State Tournaments without as many frills, bells and whistles.
Last year I directed a local tournament for New Hampshire. We hosted thirty-four teams and had a blast. The gymnasium was free, the local highschool boosters sold pizza and snacks, and the tournament tables and competition elements came from coaches around the area. We blasted lots of loud music into the gym from my own home stereo system, and a crew of friends and business associates came in to ref and judge the event.
If you enjoy kaoss (sp?) and work well under pressure I highly recommend running a tournament. It was nuts but everyone that worked with me to put it together (we did it in less than three weeks) said they would come back and do it again. It ranks up there as one of the most rewarding experiences in my life. Six hundred screaming kids, adults and fans, an all day event. Surrounded by energy. And sure enough, we're trying to do it all over again. :-)
That's where the tournaments come from.

Hello, city cats,
You cannot just use regular string. Lego string comes in some of the current Lego kits
that are available at toy retailers such as Toys R Us. However, you would need to buy
an entire kit of many other parts if you buy your string that way. If you want only
string, you can but it at the Pitsco Lego Dacta web pages ( http://www.pldstore.com ).
The smallest kit of which I am aware is $7.50, and includes string and a few dozen
rubber bands. The kit is # W779940, and can be viewed at the link below.

- Message by: Mindstorms Mayhem 12/11/2002 02:19:23 GMT
Urban Droidz,
That sounds like a cool idea to use a probe robot to go over the bridge. Assuming
that the cord you refer to is a long wire (or two) connecting the probe back to the RCX,
you cannot have a team member hold the cord up while a mission is in progress. That said,
you could have the main part of the robot hold the cord up somehow while a mission is in
progress.
However, if you are asking what can be done after the main part of the robot is back
in base, but the probe robot is still out over the bridge connected to the main robot
by a long wire, and the mission is over, I'm not quite sure what is legal. Is there
somebody who has served as a referee at a tournament that would know how to
handle such a situation?

Discussion: adults programing robots By: Roboscorps 12/12/2002 00:25:48 GMT
It's not fair for adults to program their child's robot and their teams win at tournaments. We've seen this happen on a few occasions. Because of this, teams that program their own robots don't always win. Our team thinks there should be something about this in the rules. The kids should have to program their own robots, and if they don't, and it is discovered, they should be disqualified. In the tournaments, judges should require that the kids go into a judging room and re-create a program that gets lots of points by themselves. But thats just our teams opinion. Thanks for reading this!

- Message by: Bremen Botz! 12/12/2002 00:25:48 GMT
To the best of my knowledge, the Performance Award is only one of many that FIRST awards at each competition. One of the reasons the Performance Award is given the most attention is that it is the only one that is not subjective. The team with the most points wins it. Every other award is based on subjective evaluation of the material presented.
Last year at state, there were two teams that ran perfect scores. I know both coaches and know that the kids on both teams did the work as it should be. Neither one of those teams got a robotic design or programming award in spite of being only 2 of a handful of teams to successfully complete all aspects of the challenge in the country. They were simply awarded 1st and 2nd in performance and nothing more. It really appeared that an effort was made to spread out the awards to as many teams as possible. I don't have a problem with this philosophy as all teams invest a lot in the challenge. It would be nice to know the philosophy in advance though.
This having been said, I agree with you that the kids need to do the work. There is room for coaching input and guidance (FLL suggests involving engineers and such with the team), but the challenge solution belongs to the students.
I am a veteran coach, with a rookie team (due to a move). It is not realistic to expect every student on the team to be an expert in every aspect of the challenge. Not every student on our team can write a program, build a robot, or give a presentation. We do have some that are great at one or more of these tasks though.
I guess that I am in the middle somewhere. I have a 14 year old on the team that probably should be working for Microsoft. (His dad is network engineer for Cisco). My son has built robots that placed top 2 in the state the past two years. I also have 9 year olds that don't understand it all yet. I guarantee that they know MUCH more about it that they did in September, but they don't know what the 14 year old knows. My job as a coach is to identify the talent, utilize it to solve the mission as best we can while training the younger ones to be those leaders in the years to come. I would hate to not use our best programmer because our youngest member cannot comprehend what he is doing yet.
Sorry for the ramble.... I have been watching the thread and agree with you that parents should not be the ones to do the work. Thankfully the judges are very aware of the signs and make good judgements regarding the subjective awards. The Performance Award is not subjective, and barring solid proof, it would be hard not to award it to the high score. That is why FIRST minimizes its value.

- Message by: Eco-Nuts 10/07/2002 19:01:00 GMT
The rotation sensor will count up going forward and count down (and negative) for going in reverse. The easiest way is to reset the sensor each time you want to use it and then monitor for an event of >= x ticks for forward motion and <= -x ticks for reverse motion. The x is based on how many rotations you are waiting for. You can determine this by setting the rotation sensor on one of the inputs, download a simple program to set up the input for the rotation sensor. Use the view button to scroll through the i/o until the arrow points to the desired input. Move the robot the desired amount and view the counts. Then program the delta counts in your program.

What are you not agreeing on? What tasks to try? How to achieve them? What kind of wheels to use?
Here's an option: Take a vote, and spend one day trying it that way. Then spend the next day trying it the other way. On the third day, decide which worked best.
Here's another option: Draw four columns on the board. List the good points of the first proposal in one column and the bad points in the second column. Do the same thing with the other proposal. Now see if there is a clear answer everyone can agree upon.
How to build and how to program are not the most important things you will learn in FLL. Working together and finding creative solutions to problems is the most important thing. And it doesn't come easy - you have to work at it.
But hang in there, you'll make it!

In addition the calendars, Chickfila will also allow groups to do fundraisers with their baked goods like the brownies and cheese cake. The calendars have sold really well, one of our team members sold almost 30 of them in less than an hour in his neighborhood. If everyone sells the calendars they checked out our cut will be several hundred dollars, more than enough to pay for team tshirts.
Also, some CiCi's Pizzas will let groups do fund raisers, they will set aside a particular night where if people buy a meal there a portion of the price of the meal goes towards the group. If you do this, set up a collection box for people to put their receipts into.
There's always the standard bake sales and car wash, only don't charge a set price. Ask for donations instead.

We do team tshirts and in exchange for sponsorship we will advertise a company by placing their logo on the back of the tshirt.
Is a sponsor gives $100 or more they get name plus logo, if they give $50 or more they get their company logo on the back of the team tshirt.
We find it easier to approach smaller companies as potential sponsors. The big ones get hit with so many requests for sponsors from youth groups they are less willing to do so, especially if they are not familiar with FLL.
We also sell Chickfila calendars as a fundraiser. They will give youth groups a portion of the sale, in most cases $2 per calendar. For $5 people get a great calendar that has over $20 in free food coupons good at any Chickfila across the country. The 2003 calendar has a CowBot month, so that's a good sell. The thing that is nice about the calendars is if you are unable to sell all you check out, you can return them. You are not required to pay money up front to sell them. They are a very family-friendly company and their calendars are a big hit each year.

How much money do we need to raise per year? Aside from the roughly $500 for the kit, $50 for the registration fee, and $100 for t-shirts, what else is there?
- Message by: FIRST Knights 09/27/2002 19:16:24 GMT
Batteries are very expensive. There is a cost to the table, if you decide to build it. Also at the competition most new teams, and I believe all old ones, pass out "something." The most popular item is buttons with the team name and logo. Last year, one of the teams trimmed wood to about 1/4" x 1.5" x 10" and wrote their name on it in magic marker. We were sponsored by the Knights of Columbus and bought a case of the Tootsie Rolls which are given away to raise money for the handicapped, and then printed address labels on them with our name and passed them out. Some teams had matching hats or something besides just t-shirts.
Professionally printed t-shirts for us were over $200 because of a minimum quantity of 24. (This year we don't have to buy any.)
A very easy fundraiser for us has been Ice-pops. (I don't know if that is their name, but they are the flavored filled plastic tubes which you freeze.) We bought a bunch of cases at Kmart at $3.00 per case for 88 pieces and then sell them for $0.25 each. At a school of 85 kids we took in $13 the first day.

- Message by: Eco-Nuts 10/04/2002 19:41:15 GMT
That depends on how much you need. This should be a non profit event. How much do you intend to spend. You only need the registration for FLL and registration for a tournament(150 + 45). Any money beyond this is up to you. If you have someone with a Lego Mindstorms kit or you have purchased the kit prior, then there is no cost for building the robot. If this is your first year and you do not have a kit, then you need to purchase one either from FLL or from a local store and add the extra peices needed. The $50 for the challenge kit is not absolutely necessary but highly recommended. Some people share the kit with others so only one is needed for several teams. The rest of the money you would need are for shirts (usually you can find a sponsor for this) and costs to get to the tournament. Without any sponsors, the cost is usually between $300 and $500 for everything.

You will need about 100 dollars more. You should prabably build a table for the mat. You might also want to buy the coaches a gift certificate,too. You might want to spend a little money in buying snacks for long sesions and batteries. Lots and lots of batteries!!!
- Message by: B.O.B. 10/06/2002 06:17:08 GMT
That figure is too low, imo. Even if someone already has a Lego Mindstorms kit, it just doesn't take into account the actual cost of doing a team. I think $600-$1000 is a more realistic based upon actual costs when all is said and done for a typical team.
Most rookie teams do not already have Lego Mindstorms or Robolab set, so someone has to spend $200 to start.
I don't see how a team could get through the challenge without spending the $50 for the challenge kit. You would not be able to duplicate the mat. For those who did Volcanic Panic, you all know what a difference the surfaces made in performance.
Plus realistically you need at least one practice table, even if several teams share it. So add $50 - $100 for building supplies.
During a team challenge period, you will go through many, many batteries over the weeks of practice. We went through about 60 batteries during a one day competition. They are not cheap.
If you can get sponsors for tshirt, that's good. Most teams that go to competitions will have that expense. Plus there are banners, posters and things like that.
And if you do the research assigment, there will costs associated with that, including copying expenses. If you do something like make a model, that adds to your cost too.
Then there's also photos. Many of the teams will do team notebooks that show pictures of the different stages of progress.
Plus you also have to print the challenge, so add in printer paper and printer cartridges. If you print out team logs, that adds to cost too.
At many of the competitions teams will also have give-aways for the other teams. Some sort of swap of fun items, so add that to your cost. While it's not essential, it does add to the fun of the day.
If you travel to an event, there's also travel costs.
The first couple of years we paid for most of the expenses ourselves. We split travel expenses between families. We did fundraisers to help off-set the cost both this year and last and we got sponsors that we put on the back of our tshirts.
If you already have your own Lego Mindstorms kit, I'd say aim for at least $500 in funds. If you don't and are starting from stratch, you need more.

Another reference point: I have both a returning team and a new team this year. I aready have a playing field table from past years, so add maybe another $50 if you need to build a table.
Your costs may vary
Returning team costs:
$150 team entry
$ 50 Challenge playing field elements
$ 60 tournament entry for WI ($35 regional, $25 additional for state if qualified)
$ 20 worn / additional parts from PITSCO (a rotation sensor)
$ 20 approximate printing costs for notes, challenge, etc. (absorbed by school and me so far)
$ 0 batteries -- bless those rechargable alkalines ($40 initial investment) and turning off the RCX as fast as possible if it cannot move!
$ 72 for printed t-shirts
$ -- travel (absorbed by parents thanks to tournaments <10 miles away)
$372 total
New team costs:
$150 team entry
$260 FLL challenge kit (the PITSCO team kit + software)
$ 0 Challenge playing field elements - share with other team
$ 60 tournament entry for WI ($35 regional, $25 additional for state if qualified)
$ 20 worn / additional parts from PITSCO (a rotation sensor)
$ 20 approximate printing costs for notes, challenge, etc. (absorbed by school and me so far)
$ 20 batteries -- second set of rechargable alkalines -- already own charger

I personally would not depend upon rechargeables during a competition. The performance isn't as good as a regular battery. Fine for practice sessions, but when it comes time to try to time your missions, I'd use regular batteries, especially if you are using light sensors.
$20 for printing supplies is pretty low, unless you plan on spending $0 on presentation materials.
Our team always does a team notebook with pictures, so there's the cost of film and photodeveloping, paper, ect. Plus we always make a banner.
- Message by: ilsgreen 11/07/2002 18:19:19 GMT
For sure, there will be battery costs incurred, no matter which type of battery you use. Battery costs for non-rechargables are probably similar.
From what I read in the forums, I suspect I am in the minority for using rechargeables at competition, and a bias towards fresh alkalines is a very reasonable strategy for teams. However, I haven't been displeased with the performance of the rechargable alkalines I have been using in practices and competitions over 3 FLL seasons and 4 teams. The battery lifetime before recharging for us has appeared to be comparable to nonrechargeable alkalines for what we expect the robot to do.
Both teams I coached took on their first battery change of the season this past week after 9 weeks of learning and robot development. Other than one team learning the value of rotation control over dead reckoning on a timer (some things have to be learned the hard way by team members!), this should take both teams into this weekend's regional tournament fine. Even then, much of the dead reckoning commands have come back into control once the "supercharging" of the new battery wore off after 10-15 minutes of running the new batteries - the similar "supercharged" effect seen by some teams with fresh regular alkalines.
Last year's team took a battery change at the state tournament and had to switch from rechargeables to nonrechargeable alkalines because they put one drained rechargeable and five fresh rechargeable instead of a six fresh batteries. (Another teaching moment - the battery changer insisted he had six fresh batteries in the robot even though I had the sixth fresh battery in my hand and pointed out the sixth battery to him twice!) After the team suffered through one dead battery out of six at the pit area practice table (one dead battery out of six does make a big robot performance difference!), a fast change to the backup nonrechargables was made. The control for the robot was then similar for the next competition round from the last competition round.
I believe the one watchout for rechargables is battery voltage level, so I use rechargeable alkalines. I'm using rechargeable alkaline rather than NiMH or NiCd because the alkalines deliver 1.5 V per battery, the same as regular AA alkalines. Some of the other rechargeables deliver 1.2 V, which I believe to be low for the electrical specificaition of the RCX.

No, you don't need to be non-profit. Don't think of sponsorship so much as a donation, but instead think of it as advertising. That's how companies should be approached.
Sure companies will make out checks to individuals, sell it as advertising space on the back of your team tshirts. If you are going to a local event in particular, that's a good plus for the local sponsors. We had one person in our group who is the one handling the money, they had no problem with making the checks out to her. Then she would go spend it on tshirts, batteries, registration fees, ect.
Most of the homeschool groups in my area are not non-profit either. Too much hassle with paperwork, ect. They just are.

arctic dolphins, your question is best suited to the "Rules and Missions" area, not marketing. Ask it there.
This folder is for marketing/fundraising.
IRS - have you considered simple things like bake sales and car washes? Some pizza places will let youth groups set aside a particular evening where a portion of meals bought that night goes to that group.
Don't do door-to-door sales this year, it's too late in the season and all the other school groups and scout groups have already flooded the potential market with their sales.
What about a flea market/garage sale in your school parking lot? Ask for students to donate items they don't want for the sale. Then one of the things you could do during the sale is sell cans of coke, bottled water and snacks. Buy them at a wholesale place like Sam's Club and then resell them for 50 cents a can/or package.

At the NASA web site, you can list your team or team members that NASA will then send to Mars in a mission in 2003. You need to register the names by MIDNIGHT Friday, Nov 15, THIS FRIDAY. When you register the names, you can print a nice "certificate" that features a Mars rover/robot. The certificates would be nice to give the kids involved in the FLL The NASA Web Site is http://spacekids.hq.nasa.gov/2003
It is a nice way of getting the kids involved in the space/obotics program that is their future.

Hello,
Glad to hear from teams in MD. In my last post i was just saying that it would be nice to get a local event set up. I didn't offer to host one though. The team is just now reading the rules and getting adjusted to the scope of the research portion of the challenge. It looks fun though.

Oops, sorry I misunderstood -- I thought the Annapolis FIRST you mentioned would include us. My mistake. Anyway, we would be happy to exhibition or compete with other Mayland teams. Our restraint is that we meet in the basement of my home. So I'd be happy to help organize an event, but it can't be here. We competed at The Franklin Institute last year. If anyone wants to know what it was like, just ask.

I also am "in the basement" so would not be able to host an event. I would be happy to get involved with finding a place though, if we can find a general area convenient to all.
I registered our team for Franklin Institute this year. Was it a positive experience? How did your team do?
- Message by: DMS Engineering 10/06/2002 15:51:02 GMT
I would have to check specifics, but we could host. What is the time frame? January is when i think my team would be ready. We only meet once a week for an hour.
Judges, tables, and computers would be factors to plan. We are currently being wired for the internet so we only have online access in the library. I guess we don't need that for the actual tourney.
- Message by: B.O.B. 11/10/2002 05:45:25 GMT
Howdy,
Just a couple of comments, for a competition you don't need internet access, all you need is power for the teams to plug their computers into. For an informal competition have several of the teams bring their playing fields. If any of the teams have their tables set up such that they can move them easily, they could bring them. If not, you could set up tables on plywood on top of sawhorses or folding tables, or even on the floor as long as you had the overhead lights.(directions are at the FLL website for building the overhead light part.)
If the place you are holding the event doesn't have tables for teams to put their computers onto, just have some of the teams volunteer to bring their own.
You could get judges from your local community. If you charges a modest entry fee, that would help pay for participation ribbons.
For any of the teams that do the research portion, you could just have them set up their displays in a particular area, then in between rounds, have the judges talk to them about what they did.
Seems to me that at this website (maybe under history) there is a document that talks about how to host an informal local event.
Here it is:
International > Teams and Tournaments > Host or Post an Event
http://www.firstlegoleague.org/sitemod/design/layouts/default/index.asp?pid=10240
and
http://www.firstlegoleague.org/sitemod/upload/Root/America/Local_Event_Guide.pdf
Just curious, but are you still meeting just once a week for an hour? How is your team able to do the missions in that short of time? It's taken our team awhile to plan. An hour once a week is really short. Some teams that aren't doing events until January are just doing once week but meet for several hours each time. Our team is going to a Dec event so has been meeting twice a week for 2 hours, plus doing things outside of the meetings on their own. As it's gotten closer to our competition time, we're moving into 3 times a week, with only part of the team coming each time and we've had some doing a research meeting at another location while the rest of the team meets to work on the challenge.

Susan,
The answer to your question, "How is your team able to get the missions done?" is- not very well. We are way behind. This is my first year. I've told the team they need to come in more than once a week but so far they haven't shown. As a result, they haven't even got the "props" built yet (bridge, tower, etc.). We'll hang in there. I just got the table built 2 weeks ago.
I am going to ask some grad. students at Johns Hopkins Robotics lab if they would like to judge. I participated in a workshop there this summer that got me interested in mindstorms.
Thanks for the info.

Hi Chris, I enjoyed talking to you the other day about our January event. As a first year team also, I thought I'd let you know how our first competition went. We went to the Lansdale Catholic tournament north of Philly last Sunday. There were 30 teams entered, and I must say, they ran the event really well. Our kids at first had the proverbial "deer in the headlights" look on their faces as they saw some of the other "robots" that other teams had. During practice rounds, they were watching the other team's contraption more than our own. Being a basketball coach from way back, I then huddled them together and gave them the "focus on our own game" speech. But, it really is amazing how teams can build on previous year's experience. Our humble little robot was completely outclassed by most of the other teams. I knew we weren't ready to compete for the gold, but I really underestimated how much more sophisticated other teams were. As it was, we finished 18th out of 30, but more importantly, my 4 kids were hooked on this. Upon getting home at 9 oclock Sunday evening after a 2 and half hour drive, my kid thought it a good idea to take off the tracks, switch to wheels, and triple the speed of the robot. His enthusiasm all week has been really neat to see. Not to make this too longwinded, but the other disadvantage our team has is the technical incompetence of our coach (me). Our kids have done 100% of the work with me acting only as a coordinator, scheduler, and table builder. Every once in a while, I'll input things like "why can't you do this or that?" By the way, our high score was 144 for our 3 matches. The team that won the event scored in the upper 200's, meaning they accomplished almost every mission.
My advice: stick with it and once your kids get into the programming and problem solving, they will kick it into high gear.
Finally, I'm finding it very difficult to find events to enter. I did enter us in Delaware's tournament for January 25th, but I think we got rejected by Pennsylvania's State tourney because we are out of staters. Next year, we MUST set up a Maryland tournament.
- Message by: Winterberry 10/06/2002 17:37:23 GMT
January is preferred by us, too. I'd be happy to discuss our tournament experience from last year. Also, since we have so few teams, exhibitioning (noncompetitive) would also be valuable to us. One of the huge drawbacks of the competition we attended last year was the lack of time to observe the other teams' robots. I'd like to offer to host a coaches' meeting to discuss anyone's issues. (This forum can be helpful, but it's still very confusing.) Let me know if you're interested.
- Message by: DMS Engineering 10/07/2002 21:17:35 GMT
A coaches meeting sounds like a good idea.
Also, will any MD teams be entering official tournaments of other states? Is Pittsburgh the closest?
At our "exhibition" meet will other teams be doing the Research Presentation part of the challenge or just the robotics on the table missions?
- Message by: The Golden Arms 10/08/2002 20:24:45 GMT
I was thinking of doing just the table competition. I really don't know anything about the research part of it. But maybe I need to read up on that part of it !
I also signed my team up for an event in Lansdale PA, north of Philly, for Nov 24th (or 25th?). It costs $45 and every team gets a trophy. And I signed us up for the Pennsylvania State tourney in Philly for January 11. They supposedly give first priority to other Pa. teams, so I don't know if we will get in or not.
Coach's meeting is a good idea. Maybe some time within the next month so we can discuss the logistics of a get together and our progress.

I know this is very late in the season (or after the season is over). Unfortunately our team has not progressed very far this year. However we do want to have a meet if just to help organize things more for next year. Also my team did not enter any tourneys this year.

This forum is supposed to be the place to connect with teams in your state. However, traditionally the forums have much lower participation than the actual number of teams, so it is possible that someone from a neighboring town of yours will NEVER see your posting.
How about every Mass team the reads this post a reply to it, stating where you are, how long you have been involved in FLL, and other info? That would be a start.
FLL seems to be trying to encourage participation here, with posting of the rules, and hopefully Q&A postings, but there is still the security "barrier to entry" (i.e. team name and password) that will keep 50% out, no matter what you do.

- Message by: SharonA 09/24/2002 18:38:08 GMT
As a sample "who we are" posting:
The Sharon Youth Robotics Association is a independent organization formed to create a town-wide "league" of robotics teams in Sharon, MA. Sharon is half-way between Boston and Providence, RI.
We are 3 official teams in FLL this year, our 4th year of participation. However, we form smaller "mini-teams" around parent coaches and robots where the building and programming are done at home. Then, every Wednesday night, we all get together and run the robots against each other and the clock, sharing (stealing!) good ideas and discussing rules and strategies.
Once the tournaments approach, we determine the best robots and operators to send by holding matches at our Wednesday meetings. In the past, we generally have had as many as six or seven robots being run. We then select the 10 students per official team who will represent us at the tournaments in a combination of merit, schedule, and lottery.
This approach gives us a lot of good FLL activity even we never get into a tournament. And when we get to a tournament, we usually do well because of the practice and competition that has already happened.
We have entered the Upton tournament, and have applied for spots in both Quincy and Worcester.
The students pick the team name(s) (which is why we have boring names like "SharonA" right now -- the names have not been picked for this year). We also design T-shirts, and would love to hear from other teams on how to get good ones at low cost.
Our Wednesday meetings are open to all. They are held in the Sharon Community Center from 7-8PM. Contact me for directions if you plan on coming. Priority goes to Sharon teams for mat time, but we wouldn't mind having other robots run if we have time. Near tournaments, we usually don't.

I did that on September 13. So far, I've received no confirmation or other communication about it whatsoever. I am definitely NOT impressed with the whole registration setup. As a rookie team, we've nearly fallen through the cracks a couple of times. I'm still trying to find if there are any other western Mass teams, whether we are registered for a tournament, where and when it will etc.
Fortunately, our kit showed up last week, so the kids are busy, and our Team Manual finally showed up yesterday, so I can figure out all the things we missed doing.

This team has applied for: Western Massachusetts FLL State Tournament on 12/14/2002
The problem is, I can't find anyone who will admit that there actually IS a western Mass tournament, never mind tell me where it is! I don't even know who I should ask. The e-mail came from pitsco. Should I call Pitsco? FLL? USFirst? Someone local?
It is made more difficult by the fact that the Teams and Tournaments page doesn't work in Internet Explorer on MacOS X, so I have to run netscape just to select a page. Once I get there, it tells me only about the Eastern and Central tournaments.
Sorry to get so exasperated, and thanks for all your help!

You are correct to be exasperated. The problems with browswers, etc., are reflective of a widespread "just do it for the majority" attitude that unfortunately is not limited to LEGO (Mac version of RIS anyone?) or FIRST. But we can't solve that here.
I got an answer that said "western" mass when I applied for Worcester, which was listed as "central" mass. So you are applied. Hope you get in, but you won't know until November, they say. You can ask the Teams Coordinator at FIRST, and she can tell you if your application is in or not.

Okay, I guess I am confused again. Why would our team NOT be in the WPI tournament that we signed up for? As far as I can see, there are only 35 teams in all of Massachusetts, and the Worcester tournament says it has a capacity of 40 teams. Are there some secret, invisible teams that only FLL knows about?
With all of the information that we've given to FLL when we registered our team, again when we registered for a tournament, and again when we registered for the forums, why is it so difficult to find out answers to simple questions, like, where are the other teams in Massachusetts????
- Message by: SharonA 10/03/2002 21:27:49 GMT
Welcome to FLL. They never give out the information you are seeking.
For example. How do you know there are 35 teams in MA? You don't. You have a count (probably) of those that have registered for the forums, from the teams and tournaments page. That is a fraction of the teams out there. It is a bigger fraction than the past, probably, but still a fraction. I believe I heard there were 80 teams in MA last year or the year before. I don't doubt there are more this year.
FLL just doesn't make a list available. We are provided this forum to get together, but we aren't going to be provided with the names of teams that haven't signed up for the forums, and, as you can see, most of the teams that do don't fill in the silly questions that you are restricted to in the team page (can you blame us?).
I know I say this too much, but things are getting better. In the past, there wasn't even a way to know about tournaments except THE official one! But they still seem to be deathly afraid of simply publishing a list with towns on it.

No. Secretly (meaning confidentially to the teams invited), FLL invited some teams to Florida last year, I think in conjunction with the FIRST (high school) robot event. There a small tournament was held. This appears in the "news" section on the FIRST web site. No information on how these teams were selected (or even who they were) was provided.
Officially, the events stop at the state level.

Now I am very confused. As far as I can tell, the only way to get a copy of the Challenge Rules was on this website. And the only way to see them was to register for the forums so you can login.
This means either that there are teams who do not have the rules, or there is some inner sanctum of secret teams who are given the rules in some other way.

All of the rules are available without registering for the forums. The tournament rules that appear in the forums are for the most part a numbered version of what appears in the team manual. All of the other stuff (scoring, mission models, etc.) can be had by anyone without registering for the forums.
Now, the ones here are more up to date than in the team manual, and any additions are supposed to be published in the forums.

If you mean the team doesn't appear on the "Teams and Tournaments" list, I think it means the team hasn't signed up for the forums. See the Team Updates on what you are supposed to do.

To my knowledge, nobody has heard a peep. We have two applications in. It doesn't help that their blurb on the FLL web site says "More information to follow by 9/20".
It would probably be worthwhile to write to FLL about it. I already have. The more, the merrier.

Jack,
I spoke to Mike Brown from Gillette today in regards to the Dec. 7th Quincy tournament. He will be emailing teams this evening with confirmation information. We had registered our team through the FLL website for this tournament and received email confirmation of doing so from FIRST but he did not have our team info nor were we registered. Fortunately for us he was able to fit us in. I believe that any team he received information on from FLL is "in". Mike said to put the word out that if you do not hear about the Quincy High/Gillette tournament by tomorrow and you registered through the FLL website to contact him.
I hope this helps,

No, this provides a list. This list is not clickable, has no information other than the team name, and most of the names listed cannot be found if searched for under the Team Search feature.

We are fielding three teams from Qualters Middle School in Mansfield. In the forum, we are called Mansfield A, Mansfield B and Mansfield C. We are all rookie coaches and would gladly accept any advice anyone can give us.
We have been trying to sign up for a state tournament, but haven't had any e-mail response from the contact listed at WPI and there doesn't seem to be any info on the North Quincy tourney yet. What's the best way to get registered and should we have that accomplished by now?
Also, can a team participate in the local tourney in Upton and also at one of the state tourneys? Looking forward to this.

Yo! Mansfield. It is very confusing, but you have to apply for the state tournaments through FLL. Each Team (A, B, C) can apply to one tourney. It doesn't mean you will get in. We put two applications in for Quincy and one for Worcester. Look hard on the tournament pages and you will find the application link.

Of course, how silly of me.
When I was building the bridge last night it seemed entirely obvious how the bridge was laid out, now, looking through the building instructions and the pictures available I can see it's not very obvious.
I'm thinking that there is some wording on the mat that indicates where the pieces go. I know they have that for the other structures (windmill's push bar, short wall of market, etc.) I just can't remember if there was for the bridge and I don't have the mat with me to look at, so I'll have to follow up this evening.

First, you do not have to re post a message, you can edit or delete a message up to 30 minutes after posting.
Next, you will have to be more specific about your problems. The programs are designed to run in separate slots on the RCX. You can select which slot to download a program on prior to downloading. Within a program you may have some problems. You can display information to the display window and use that to debug how your program is progressing (is it following the paths you expect it to follow). In RIS this is small blocks / comm/ display value. You can display a specific value for specific paths and determine if you are getting to the correct path. You can also add end program to certain paths again to determine if that path is being taken. It is always a good idea to end all your programs with an end program block. More specific questions will help debug your problem. If you would like to e-mail me privately so as not to give away your strategy to everyone, I will give you back comments as I can.

- Message by: Eco-Nuts 10/17/2002 15:22:29 GMT
You can do several things. Look at how the bot is built. Look at the axles for each wheel, are they equal in friction? Do they spin equally well without a motor? If using the standard bushings look carefully at them they are not the same on each end. One will offer more friction against a lego hole than the other end. If you can not remove friction from one try adding friction to the other. You can add an extra gear (a gear that does nothing). If all else fails than you can prgram different powers to each motor and try to even it out that way. When all else fails do not rely on straight motion and use a line follower to just follow the lines to your destination.

The side with the lever is NOT closer to base. The lever goes on the part of the bridge that sticks up in the air, and the mat indicates that that part of the bridge is on the other side of the "river" from the base.

First try to buy your batteries in bulk. A couple of places
on the web including www.digikey.com sell bulk at 1/3 the
cost of a store.
Second, for practice you can use rechargable batteries. It
is expensive to start, but if you are going to stay a team
for a few years, it will pay for itself. Check out my manual
at http:/home.attbi.com/~pssweeney/handbook.pdf It has a
section on the right type of batteries to use.

Most rechargeables produce slightly less voltage than their alkaline counterparts. The extra power can make the difference when you have to get things done quickly. Also, most rechargeable give little warning before they go dead.

Discussion: Movement and Accuracy By: Tri-Valley Bulldogs 11/01/2002 18:20:36 GMT
Our Roverbot drifts to the left and our Acrobot does not turn, not even with a pivot wheel. We tried taking off the 4-Wheel-drive and changing the tires and we're just clueless on the acrobot
- Message by: Eco-Nuts 10/18/2002 22:30:20 GMT
No two motors behave the same. It is extremely dificult to build a robot with independent motors on two wheels to not drift. Friction is never the same for a given setup. Most two wheel drive systems that work with two motors will drift. A 4 wheel drive system uses what is known as tank steering. Even though you have 2 wheels on the side they should be geared so that power is going to both the wheels and driving them in the same direction. When turning one set of wheels is driven forward and the other set is driven backwards. This forces a sidways motion on some of the wheels and will turn the robot. The problem with 4 wheel drive systems is again they also will drift and the repeatability of the turns. This is why there is no single answer to which is best. They all have their problems and it is up to your team to decide on which one you can work with the best.
The most common way to make a robot go straight is to use a diferential gear to force both wheels (left and right) to turn an equal amount. You can use one motor for going forward and backward with another motor for turning. You can also set up some where forward is locked and you lock one wheel while backing up and forcing the bot to turn while going backwards.
A solution for your drift problem is to use the light sensor to follow a line to get as close as possible to your objective and then move off the line as needed (minimizing the amount of "straight" motion needed). Another is to adjust the power to the motors or add some slight turns to adjust for the drift. If the drift is predictable, just let it be and work around it.

- Message by: Eco-Nuts 10/29/2002 16:59:16 GMT
This has been answered elsewhere. You can do what you like in the base. There are no restrictions on how many you take at a time. You can handle, stack, place in container, whatever your mind can come up with as long as the deliverable is not damaged while it is in the base. Don't add rules that are not there. The rules are somtimes vague to allow you the flexability in deriving your solution. While some will stack the houses in the base and deliver the stack, others will deliver one house at a time and stack them on the field (creativity points). Do what your team can accomplish reliably in the 2.5 minutes.

Discussion: Judging for State Qualification By: Metrobots 12/04/2002 23:25:22 GMT
This discussion is about the following judging rules and determination of what teams qualify for state.
Robust Design 10%
Programming 10%
Innovative design 10%
Quality Research 10%
Innovative Solutions 10%
Creative Presentation 10%
Teamwork 20%
Performance 20%
I was shocked at the local competition yesterday when i found out about new judging and scoring rules. How does everyone else feel about the new qualification rules? Here is my take on it.
1. Timing of judging rules available to coaches: I went to the website immediately after getting home and found that this information was posted on October 29, when most teams are feverishly working to get their projects completed. They already have a plan and it is too late to change much of their strategy for research and other areas. It was only 3 weeks before competition. Coaches who planned ahead and didn't visit the webite much after the first few weeks missed this information entirely.
2. Kids that are attracted to this kind of competition are often shy and quiet. They would rather let their robot speak for them. They work just as hard or harder than other teams but have a hard time articulating that to the judges. Only the coach is aware of their dedication, research and teamwork. Although it looks to be balanced, the judged areas, a full 80% of the score is based on how well the kids can tell the judges about their experience. They have to tell the judges about the robot and programming not just show it. It is language arts not science and technology anymore, that will win you a place at state.
3. The FLL is now rewarding mediocrity not excellence. If a team does okay on the table and okay in the research then they will rise above teams that do an exceptional job of either one but poorly in the other.
I am very disappointed that the team that got the 3rd highest score on the table did not earn the right to compete at state (8 teams qualified). That is not my team that I am talking about. My team was confused about that and about the fact that a team that scored lower that us got to go to state.
I think the new rules do not adequately represent FLL and that there are other ways to more fairly judge the teams. I also think that rules need to be decided before the challenge is posted and available to potential coaches. I may or may not come back as a coach next year. I hate the thought of helping a team work hard for months knowing they will not be able to make state because they are shy and cannot tell the judges what they have learned. I do not want to hand pick team members on their personality. I want them because of their desire to participate.
My 2 cents. I would like to see FLL comment on this.
- Message by: B.O.B. 11/25/2002 22:08:44 GMT
I think you raise a valid point about notice to coaches. I looked the Michigan FLL website and noted that they did not update the new rules until 11/11. That's not a lot of notice to teams.
http://eng-sci.udmercy.edu/precol/fll/
There's quite a few teams that don't use the forums at all, so they would have received notice even later than the 10.29 posted in these forums.
It does clearly state that if a team is top in a particular area that doesn't mean they will automatically get to go to state. I think that would be hard for some teams. For example, some kids don't do well with research or public speaking but would be very good programmers and builders.
Part of what I think it nice about FLL is it does have a variety of awards to recognize that different teams will shine in certain areas, that more than just the robot challenge performance itself counts.
Because Michigan has so many teams, I understand the need to have local competitions first. Perhaps if you can think of a fairer way to deal with that, you can pass it onto the Michigan officials.
- Message by: ilsgreen 11/26/2002 04:58:28 GMT
I'm sorry to hear about the late notification of the Michigan scoring. However, I'm fairly sure the director's criteria was more generally covered in the awards section in the start of the team manual sent with the team's registration package. The tournament organizers have to pick something for state qualification, so the best composite scores (plus in Michigan, I believe the highest performance score) in a regional seems reasonable based on the awards shown in the team manual.
It seems like a lot of effort goes towards a functional robot, so on first glance it seems like robot performance should be 50% or more of the composite score. However, I am a supporter of a mix of verbal discussion and actual performance on the judging. One of the biggest educational purposes of FLL is a chance for kids to see what science and engineering work is like. As a person working in research and development, I can assure you that both the actual technical aspects, the process used to achieve results, and the ability to communicate the technical aspects are both important to technical project success. Exposure and development of these skills is what FIRST strives to do through FLL.
I've also felt that at every one of the four tournaments where I've coached a team, I'd personally be just as happy to call it a day at the end of the all rounds and skip the awards (this coming from a coach of teams with 2 state Robust Design and 1 Director's 2nd in past years!). It's rewarding to do the best possible work as a team. It's rewarding to help chip away at personalities to be able to work as a team. It's rewarding for the team members to learn tons of things about science, computers, and technology that kids would never see in the classroom, team members could do. It's rewarding to be around a bunch of teams who have fought the same battles at the tournament - perhaps it's a competition, but it really becomes more of a competition to develop and show team member talents to their best abilities. The tournament should make a great celebration of everything done in the last 8-12 weeks. And my best memories of this aren't the trophies -- it's the process, the learnings, and the "war stories" that make for my best memories, so I work to convey that learning excitement to team members.
To support the goal of learning about science and technology in an exciting way, I feel it's necessary to separate what the team members learned from what the coaching staff did. The technical interview with team members without a sound from -- and generally without the presence of -- coaches and mentors serves this purpose well. I've watched a fair number of pinecar derby competitions where I'm not always sure how much of the car was child effort and how much was parent effort. One reasonable way of measuring team learning and knowledge growth is the technical interview.
For my teams, technical interview preparation tends to be more informal. I don't rehearse it, but I do these two things: 1) Tell them that the judges are interested in hearing about your robot and 2) provide a review sheet discussing things learned during the year to help jog the memory of team members. The review sheet becomes a different way to analyze all of the time spent trying to get a robot to do missions. I also end up doing printouts of the programming that are a requirement for the technical judging primary due to printing issues at our classroom practice area, but the programmers have lived through enough of the programming to know what's in the program at the end. While there is some speaking involved, the technical interview (in Wisconsin) is led by the judges who informally ask questions and give the chance for the team to provide answers. The judges have also been good about staying kid-friendly while probing about aspects of the robot and programming when there might be more detail. All of this helps my technically orientated, scared of public speaking
- Message by: ilsgreen 11/26/2002 05:00:11 GMT
(continued - glad I'm copying and pasting now!)
team members do reasonably well in the technical interview.
The scientific presentation seems to be more of a public speaking effort once the reserach is done. Team members can still contribute to the research and ideas even if they are frightful of speaking - and I have team members who are frightful of speaking. I also have one team member who is starting to flourish as a speaker in her second year. Another team members started to take ownership of effort when he started working heavily at the scientific presentation. Going through the process of asking and answering "Why?" is still an area I think is critical for scientific and technical learning, whether it is on the robot or on the scientific theme of the tournament.
It's awfully difficult to do well at the performance table without having developed a good robust design, good programming skills, and some innovation in design to slve a problem. In Michigan, this would be 20% for performance score plus 30% for robot categories (10% robust, 10% programming, 10% innovative), so I'll say that 50% of the overall score is based on direct robotics. Additionaly some innovation, developing some ability to ask and answer "Why?" in both the scientific research and the robot's performance, and developing some semblence of teamwork and cooperation is often needed for robot success, so I'm not itching to see these items get lost as judging criteria.
A tweak of weights between scores in Michigan might be considered in the future. Each state tournament is a little different, so I'll give flavors from other states. For this year, Wisconsin is scoring 16% innovative design, 16% robust design, 16% programming, and 20% table performance, or 68% based on direct robotics. Teamwork is 16% and scientific presentation rounds out the final 16%. In 2001, Minnesota (see Tournament planning at www.hightechkids.org/fll) calculated composites at design 16.7%, creativity 16.7%, programming 16.7%, and performance 16.7%, making composite scores about 67% robot-based. Both states are also using regional tournaments to determine state qualifiers.
Hope your team is jumping to come back for more learning and excitement next year,
Mark Beitz, a coach who coached two teams this year: one going to state and one not -- but both teams did great things!
- Message by: Gridlock 12/04/2002 23:25:22 GMT
Is it not our jobs to inspire kids to take more interest in Science and Technology? Is getting to the state level the only reason we are involved in this? Do we really need to prove something?
We are here involved in this program to learn not to bring home the big trophy, the only reason there are awards is to get interest in the competition. What you did together as a group for 8-10 weeks is the best award or recognition any team could hope for. Table score means nothing without the research aspect involved, that is why state level wants the best well-rounded teams. If you qualified for being the best in one area then not all areas would be covered and teams would pick and choose, sounds a bit too convienient to me.

If you all would be interested we could hold a event this year just for the three of us to prepare for whatever state event we choose to go too. Might give the kids a good chance to practice and meet others interested in the same things! Just an offer let me know.

Hello mechanics. Ho wdo you hold an event? Are there official judges? Where are you from?
We would definitely like to attend or participate in an event. We started 2 teams so that we could at least compete within our school.
- Message by: Mechanics 09/21/2002 22:18:46 GMT
There are possibilities to set up an official event although we would need to set up a sponsor pretty quick or we can just get together for a fun saturday so the teams can interact and if you brought a competition table we could even run the event as a mini tournament to give the kids some practice. Also I am sure we could get some teachers or parents to sit in on the presentation of the research project to give the kids some feedback.

I don't think we will be making that trek, but we bought 2 kits so we could compete within our own school. Would you be interested in setting up a local challenge? We're from Hermann, so we're only about 45 min. away.

We went to Mountain Home 2 years in a row. They do a very nice job with their event. We drove 12 hours from the Houston Texas area in order to compete. We won't be there this year, however, Texas finally has state competitions. This will be the first year that Texas finally has state events.
Mountain Home Arkansas is one of the larger FLL events in the country. They get the whole area involved and have been putting on a quality event since 1999. They make it lots of fun for both the students and adults.
Last year there were over 50 teams from about 4 different states. In 2000 they had over 60 teams. We'll miss not going to their event, but won't miss the 12 hour drive and are happy to have something in our state finally.
If an event doesn't happen in your area, I'd encourage you to register for the Arkansas competition. Don't worry about being a rookie team, it's worth going to the big events for the experience.

hello again to all...
Just wondering if the Missouri teams or anyone interested in coming to St. Louis would be interested in getting together a small practice tournament. I have checked into it and our Gym is available on Nov. 2, 9, 16 or 30th. SO we would like to cordially invite you all to join us have fun and see just how these things are going to work. If you are interested please e-mail me at MDSTRAHM@AOL.COM with your preferred dates and we will get things going. As a new team I know we want to try this out before we go to Chicago. Look forward to hearing from you all.

All tournaments for most Missouri teams are held at Mountain Home Arkansas. So you will have to travel. I wouldn't try setting up your own compatition with out complete knowlegde. Also your a newbie don't try anything stupid!
- Message by: Mechanics 11/27/2002 10:51:17 GMT
actually we are attending the competition just outside of Chicago in Arlington Heights this year. It is much closer for us only 4 hrs vs 6-7 hrs travel time and is a much larger competition.
- Message by: B.O.B. 11/28/2002 09:36:45 GMT
That is a large event! Up to 125 teams. I find that interesting because the LEGOLand in California only allows for 35 teams.
I think going to a 125 team event would be a bit overwhelming for rookie coaches. So bigger is not always better.
The Arkansas event is very nice, we went 2 years in a row. This year will have about 70 teams. We used to have to travel there from Texas, it was a 12 hour drive. But this year we finally have one in Houston, it will have about 40 teams and a Dallas one in Jan will have about the same. We'll see how the Texas ones go, with being first-time events.
I also agree with the comment about not trying to set up an event on your own until you know what you are doing. The Arkansas event has been going on each year since 1999 so are very experienced with running an FLL competition.
For the future, it seems like St Louis has enough science museums, colleges, and the like that one of them should be able to hold at least an informal local event. It would be a good practice run for those going to a regular competition later. If teams have to travel, that normally means that their friends and relatives don't get to come to watch to see what the teams have done.
Folder: Names to Mars, a NASA program 11/14/2002 06:52:25 GMT
NASA is running a program to send the names of kids to Mars on a rover on an exploration mission in 2003. You can submit the names of the kids on your team or your team name toNASA who then will put it on a disc which will go on one of the rovers scheduled to explore Mars in 2003. This is a nice tie in with the concept of robotics as the certificate that you can print after you submit the neame(s) features a robot/rover.

Hi Ross,
I'm curious to know what the estimated cost was last year to run a tournament. I've considered trying to run one at my school but funds are scarce. I assume entry fees for teams would pay for trophies. Food sales could add a few dollars to the awards expenses. If I can get volunteer judging help and possibly get a few teams to bring game mats, it seems a small to medium size tournament is reasonable?
The past 3 years I have run a Haverhill only tournament. Very low key, lots of fun. Bumping up to the next level would take a lot of coordination.

Hi Mike,
I applaud your interest. We had 34 teams last year. Each team paid a $35 registration fee. So from registrations we had a little over $1000 to work with. The gymnasium was free, the local high school boosters sold pizza and refreshments (the proceeds of which went to them), I made a bunch of stanchions and light stands from pvc pipe, bought four flourescent lights, and paid my DJ (not a professional) $100 for her help (my only paid position).
Most of the cost was in the trophies. I also designed and purchased about 100 tournament shirts. If they all sold I would bring in another few hundred dollars. They didn't all sell, had about twenty five left. So that became a wash.
We also purchased medalions for all of the participants but charged another $3 or so per child to cover that cost.
The tables came from the teams, so did the table elements. I built four eight-foot saw horses to hold up two tables each for a total of four tournament tables.
We used my stereo, computer and four speakers for the DJ, the basketball timer for timing the rounds, and the gymnasium PA. I spent $100 on DJ software and loaded my computer with mp3 files. The $100 was well worth it! There was no overhead monitors or screens, scoring was done by both computer and chalk board. The teams were asked to bring in their own duct tape, extension cords, tableclothes etc. All in all, I might have been out-of-pocket a couple of hundred dollars at most. It was worth every penny.
The tournament itself... well none of the kids complained! :-) I've had coaches say they've been to state tournaments and they didn't have anything we didn't have except maybe a few more bells and whilstles. But we did have all the loud music and noise! It was a great party!
Would be happy to talk about this more. I have a lot of information I put together. Your welcome to what I learned.
I say... GO FOR IT!

I agree, Ross. We went to two tournaments last year, yours and the RI state. Yours was definitely the most fun.
However, I know you are prooud of the loud music, but that was the one negative experience at your tournament. It was nearly impossible to carry on a conversation in the stands. A lot of people were grumbling about it you probably never heard from. My request, for whatever it's worth, is to please turn it down a bit this year.

Hi Ross,
I appreciate your detailed reply. One of the obstacles I'm running in to this year is I have mostly first year kids on my teams so parent support for running a tournament isn't strong yet. I'm thinking if I get these kids hooked on robotics this year, I'll be able to build the support needed to help run a good event. I still might organize something very small.
I'm hoping there will be room in one of the NH tournaments for us northern ma folks.

I am looking for interest in a local competition in Nashua. The state competition
is very likely to be overbooked and I am looking for a way to let teams compete.
Last year, Nashua held an unofficial tourney for local teams. I am considering the
same this year. Interested individuals should contact me at fll-freak@attbi.com
I am considering a date in January to give the teams a little more time and so that
teams that miss the State will have some reason to help on the local!

I understand that the NH tourney is nearly 200% overbooked. There will be many teams
that will be disapointed in not competing. The proper thing to do will be to run a local
competition for out teams in the Nashua area. I guess I need to pick a time and place
to run the competition. Any problems with using Birch Hill again this year? I would limit
the competition to 20-25 teams. Preference would go to those that did not compete at state.
Help will be needed. None of the logistics scare me other than finding all the runners and
judges. Perhaps we might force the burden to the teams competing. Each team to supply
two runners and a judge? Runners could be parents, but the judge would have to not be
associated with the team.
Comments welcome.

Welcome All... it's happening again! Last year was just the "Tip of the Iceburg"! HA! This year we're doing it all over again and hoping we can make it even BETTER!
This will be a 30 TEAM TOURNAMENT to be held in the largest highschool gymnasium in the state of New Hampshire - The Rochester Recreation Center.

Application for this event is exclusively by email. Event registration is $45 per team and it is these monies alone that will pay the expenses for this event. As there are so many teams registered in the State of New Hampshire (close to 90 teams), I ask that if you are selected to attend a State Competition then please do not apply. Our goal is to provide the opportunity for as many teams as possible to attend a tournament event.
APPLICATIONS ARE OPEN to New Hampshire teams only until October 28th at which time the event becomes open to all. Acceptance is on a first come - first served basis so apply NOW!
To apply please email the following information (in this order):
Team number
Team name
Team location (city)
Number of students on team
Coach Name
Coach Telephone No.
Coach Email Address (very important!)
Email the above information to:
Ross Freeman at rossfree@attbi.com
Notification of acceptance will be made by email no later than October 28th and an event team list will be posted and kept up to date on the web for your viewing... web address to be determined and posted in the comming weeks.
If you have any questions or the burning desire to talk to me please feel free to post here, or you may email or call me at my home (between 5:00pm and 8:00pm weekdays or weekends).

Hi Ross -

One question - we've applied for State, but won't know if we're in until past your deadline. Is it okay to apply to your tourney and then drop out if accepted at State? (or maybe drop out of State if accepted to yours? ;-) Are you doing a "wait list" of some kind in case teams which you accept later get accepted to State and then drop out of yours? It would be a shame for a team to wait on hearing about only one, and then not get into either!

Discussion: Rochester NH Tournament Results, 7 Dec 2002 By: Mindstorms Mayhem 12/11/2002 17:02:50 GMT
Rochester NH Tournament Unofficial Results, 7 Dec 2002
The second annual FLL tournament in Rochester NH was held on Saturday, 7 Dec 2002.
Last year, this tournament was the only FLL tournament in New Hampshire. This year,
it was held as a qualifier for the NH State Tournament coming up this next Saturday,
14 Dec 2002, in Nashua, New Hampshire.
The tournament organizers, judges, referees, and workers did a great job. The opening
ceremonies (like those in the Olympics) were excellent for making all of the students feel
appreciated. Having a Segway for the students to see in operation was really neat, too.
I believe there were 32 teams in attendance at the tournament. The performance competition
began with each team making 3 runs on the tournament tables. The best of the three scores
was used to determine entry into a single-elimination playoff for the top 16 teams. Research
presentations were made in other rooms to judging panels; technical judging was performed
similarly in interactive sessions without formal technical presentations.
Congratulations are due to all of the teams that participated in the event. I was particularly
impressed by the conduct of the teams at the practice tables. Even without a formal schedule
for practice table use, the teams "managed themselves" and took turns sharing the tables.
It was great to see the kids from all the different teams working with gracious professionalism!
Thanks are also due to the tournament organizers, who orchestrated a great tournament!
Now, for the results:
Director's Award - Mindstorms Mayhem, #1265, Milford NH (Homeschoolers)
1st Place Performance - Mindstorms Mayhem, #1265, achieved a perfect 360 score
2nd Place Performance - "50937" (look at this upside down), #1770, Concord NH
1st Place Presentation - City Swami Snakes, #25, Amherst NH (Middle School)
2nd Place Performance - Mindstorms Mayhem, #1265, Milford NH (Homeschoolers)
Robust Design - Blue Dragons, #855, Manchester NH (Main Dunstable)
Innovative Design - Mindstorms Mayhem, #1265, Milford NH (Homeschoolers)
Programming - City Fire, #1210, Somersworth NH
Teamwork - The Gear Heads, #1264, Hudson NH (Hudson Memorial)
Against All Odds - Silver Dragons, #865, Merrimack NH (Mastricola Middle Sch.)
Judges Award - Silver Dragons, #865, Merrimack NH (Mastricola Middle Sch.)
Team Spirit Award - The Electrons, #2947, Dover NH (Homeschoolers)
Also, the top ten teams in director's award juding qualified for the NH State Tournament,
to be held on 14 Dec 2002 in Nashua, New Hampshire:

Welcome aboard Wentworth Woods! I know how you feel. I was there last year. You have time. Panic later if you want. Right now you have some work to do. :-)
A coach can always do with a mentor or two. That's the first thing I can suggest. I felt responsible for teaching the team everything at first... not the right way to start. The kids have been in school all this time being told exactly what to do. Now it's there turn to think for themselves.
Coaching is asking questions like... "What do you think we ought to work on first?" Let the kids answer that question. Answer their questions with more questions like... "what do you think?" or "how would you do that?"
Help them break into small groups, builders, programmers. Let them start playing with the Legos. Use the tutorials in the software to help get the programmers started. Let the kids figure out how to hook it up. Some of these guys are computer wizzes! Encourage them to focus on the task. Brainstorm a way to solve the problems.
I would speak to one or two of the older kids in my group and ask them to take one of the younger kids on as their assistant. It made them feel more important and it helped keep the younger ones more involved.
You can also turn to the web for Coaching information. Minnesota FLL has a wonderful website full of coaching tips. Search them out.
You are also welcome to call me and chat. This stuff is fun. Don't forget to have some fun yourself.
If you have any more specific questions, any at all, post them here or you may email me. I will do what I can to help.

I haven't scoped out the missions really much at all yet. So I can't tell you if there is time enough or not. You'll find your team struggling to complete just one if they're anything like other teams... at least for a while. That's ok. They'll catch on and then stand back! Can all of the missions be done. Yeah... probably. But not necessarily one at a time. The robot may have to go out once and accomplish several missions before it comes back.
As your coach, you can teach or you can encourage. I think a good mix is a little of both. But I push my team to figure it out themselves. If they get off the beaten path too far I might nudge them a bit but I answer most of their questions with questions of my own.
They know most of this stuff... tall things tip over, rubber grips better than plastic, changing gears helps them bike up hill easier... I help them put engineering words to those things... Center of Gravity, friction, gear reduction. If I don't know an answer I'll ask them to look it up. The web can be a great source of ideas... especially with legos.
As for the presentation... I say facts over elaboration. A lot of kids don't really understand what they are talking about. If they really understand the problem, research and come up with stratagies for solving that problem, it will come across. But if one of your group has wild and crazy ideas for a presentation, I say go for it! An artist is "not to be put-off". :-)
Don't forget, this is also fun. (I know you haven't forgotten :-)
I think I'm gonna have a shirt made... "An FLL Coach is someone in desperate need of a SHRINK!"
Keep up the great work!

Wentworth Woods,
We are a rookie team as well and I hear your concerns. Sounds like some great advice was offered from Arctic Fire.
The big thing I noticed is we are so diverse in our group with talent and ability. We started there and have been working on the partnering relationship. It really helps the older kids from dominating when they are working with a buddy.
Question... Most of my team was looking at the research as drudgery. how about you guys? For the research we had each kid pick a city and they are to come back with 10 facts and and Idea for the robot. We went through one together as a team to see if they could pull the info out. We are then going to have the kids decide the city and go from there after everybody presents there findings to the team.
Any other ideas?
- Message by: City Fire 09/30/2002 22:25:56 GMT
Welcome aboard AMS6,
And thank you for the compliment! The research can be considered drudgery alright. It's like homework! Blech! When your team finally settles on a city and a problem, get them talking about the nuts and bolts . Get them to THINK. Dig into it.
I went to a "You-n-me" church camp with my five-year-old some years back. There were rules for everything. No running, can't go anywhere without a buddy, have to take a nap at 2:00... must lie on your bed for 45 minutes, if you drop a utensil you have to go back to the kitchen and get a clean one, etc...
I was an adult, there to have fun with my five year old and the rules were making me CRAZY! Little kids would come by, point at me and say, "Your not supposed to run on the path!" I was held to all of these rules! One of the mom's that had come with her daughter couldn't stand it... they left the next day. I could really empathize with her!
There is a point here. LOL
"IF YOU CAN'T GET OUT OF IT, GET INTO IT!"
After I decided not to buck the system it became fun!
Research for the presentation is a pain... it's like riding a bicycle up hill. But if the kids are encouraged to understand... really understand the problem... they will start to get into it. When an idea forms in their minds as to how to present their solution they'll be coasting down the other side and picking up speed. At some point you'll be asking how they might present their ideas in a presentation. Be ready with the markers, glue and poster boards... or WORSE!!! LOL
Help them see that the presentation trophy really means something special. And make sure they have time for legos at each meeting. Science Lab is always a lot more fun!
Keep up the good work!

Hello
I have a question about the tournaments - We have applied for the Nh state tournament but from what I understand we may not be able to participate if we don't get picked. What happens then? Do we apply for other tournaments or do we just wait? How do we handle that? Is there another we could participate in if we don't get picked for the state tournament?
- Message by: City Fire 10/02/2002 03:01:45 GMT
This is an unfortunate side to FLL. Because all tournaments are put together by volunteers it is hard to know from one season to the next whether there will be enough tournaments to handle teams wishing to participate.
As I understand it... you can only apply to one State Tournament. You will be notified by a posted date as to whether you have been chosen to attend or not.
If not, you will be searching for a local tournament to attend. Some local tournaments have been posted already. Others have not. Local tournaments, like State tournaments are also put on by volunteers. But they are done on much smaller budgets. Where State tournaments are usually backed by one or more sponsoring companies (New Hampshire State is sponsored by BAE Systems, Inc.) and follow tighter guidelines as to staffing, location and scoreboards, Local tournaments tend to operate on small budgets (much of which may come in from team registrations alone. Local tournaments may pair things down a bit, but they can still provide an exciting time for the kids.
I am working on a local tournament in Rochester, NH. It is looking like it will happen but I'm not ready to give it my seal of approval. A few things have fallen in line but there is much more to be lined up before I can say it's a go. Last year, the Rochester tournament was the only one in New Hampshire. We tried hard to make it the best time possible for the kids and didn't turn away a single team that wanted to participate. It was originally intended to be a thirty team event. We had thirty-four teams! It was great!
I hope this helps. As soon as I determine that the Rochester tournament can be a go, it will be posted here. It may be another week or so before I am sure.
Hope this helps!
Good luck with your team! :-)

I have another question! I have seen some things pertaining to community service. Is this something the kids have to do? Also, there is a lot of discussion about fundraising. Our kit was sponsored so we do not have to fundraise for that. Are there other costs we need to fundraise for? The kids are designing a tshirt but I assumed everyone would purchase their own.

Hi Marilu,
Thanks for your offer to help with the tournament. The need may arrise. I'm assembling a team of judges now. First meeting in two weeks.
On your community service and fund raising questions... an interesting thing about FLL is that the there are no hard and fast rules. You are the coach and you decide what is right for you. If you think you can work in community service, great! Fund raising... great! This camper doesn't have that kind of time. :-) I work, have three kids, I'm trying to put together a tournament and I'm coaching a team of my own.
Personally I like this kind of structure. Fll gives good guidelines, a team manual full of suggestions, etc. The program is great! But it is run by volunteers like yourself. You try to do as much as you can but you have to draw your own boundries.
I choose to have each of the kids(parents) contribute $100 as team registration. With that money, I purchase kits, supplies, notebooks, t-shirts (we design, print and iron-on our own shirts) and I set up a bowling party once in the middle of the season. The money also pays for registration to a tournament event.
Others fund raise, washing cars or selling baked goods. I choose to have the money up front and out of the way. I don't make any money doing this by the way... the money is spent on the teams needs and team members or parents may see a record of where the money is spent at any time. This year I got several more kits on Ebay. They will go to replace parts lost the previous year and will also allow more hands involved in design.
Your biggest challenge will likely be getting the team to complete their first challenge. If you are not versed in programming then plan to find someone who will take the time to mentor the kids. This person teaches a little but is mostly there to help kids understand things as problems arrise. Find this person soon! It could be a highschool student or a friend computer geek! The kids will likely need guidance in the concepts of programming. They may only need a good jump start (a couple of meetings or so) to get programming on their own.
You have a lot to do in eight weeks. My suggestion is direct the kids attention to four things... design, programming and teamwork. The fourth is the presentation.
Keep the questions comming! Call anytime if you would like!Every question you have, I asked last year. Been there done that! Have fun!

While I'm not in your state, I think I can shed some light on your questions. Community service is pretty opened-ended, think outside the traditional methods.
While it's not a requirement, community service is looked on with favor from the judges. At the competition we went to last year, the team that won the research portion won it in part because they went out into their community to educate them about global warming and ways to help the environment.
We consider educating others about FLL as part of our community service and will do demos to encourage others to consider forming new teams. During 2000, our FLL team was able to do part of the LEGO Mindstorms Mall Tour. They just happened to have a stop near us. The kids had a blast with showing all the people who came by what they could do with their robots. We passed out flyers about what FLL is about there as well. This year we'll be part of the World Space Congress's robotics demos down in Houston,TX this Friday where they will have FLL, FIRST and BEST robotics demos going on all day. The robotics expo is an educator event to encourage schools to use more robotics for education.
Community service doesn't have to be a big time-eater. We do the Operation Christmas Child shoeboxes. Kids will collect items to put into the shoeboxes and then we spend part of one meeting decorating the boxes and then one of the parents will take them to the drop-off point.
Community service is good PR for a team as well, quite a few FLL teams will send press releases to their local newspapers and more often than not, the newspapers are willing to print them.
Regarding the second part of your question, the other costs besides the team kit is going to be your practice table and batteries,lots of batteries. Plus in addition to tshirts, you'll want to take pictures of your team as they work on the challenge, those are nice for putting into a team notebook. Our team also writes meeting logs of what they did each time. (Most of the kids don't like to write that much, so they just take turns and email them so one of the team members can make the master log for that date.)
If you are doing a tshirt, consider getting sponsors to off-set the costs. Put their names and logo on the back of your team shirts, good advertising for a company. Last year we had enough sponsors to just pay for the kid's shirts, adults and siblings paid for their own. But this year we had enough sponsors that even the parents and siblings of team members costs are covered. We also give our sponsors each a shirt and the kids do thank you cards to them. The reason for doing more than 10 shirts is if you buy in larger amounts, the cost per shirt goes down. So overall that's sometimes cheaper in the long run. Our kids designed their own shirts as well, it's a fun thing for them to do and to be creative. Besides if not just your team, but all your team's parents and siblings are also in the team shirt that day, it makes it easier for your team to stand out in a crowd.

Thanks for the advice. For someone who was justing starting out last year you certainly have learned alot. I have been pouring over the materials and reading everything I can and I think I have a handle on what the kids need to do. The community service threw me off!! I wasn't sure if this was something that had to be done. I think we will pass on that this year. I also have 3 kids, a job, a husband and no time!!! Now that the dust has settled a little, I think we are on the right track. My oldest son gravitated to the computer software and went through the whole tutorial and was able to quickly built the roverbot and program it to do simple tasks. I think he has a good start on the software and seemed to think it was somewhat easy to use. We will look at programming more this week but I'm hoping we are on the right track. Do you think we should have someone do some additional teaching on programming? Maybe I will let them play with it a little longer.............. You were brave to attempt a tournament during your first year!!
- Message by: City Fire 10/03/2002 14:53:27 GMT
LOL... brave? No. Crazy.... ahhh yes! There was NO tournament scheduled for New Hampshire and something had to be done. We had a blast doing it.
Your son can probably be your mentor... but have him dig into the yes/no block. In programming terms it is the If/Then statement. Such as... "IF" the light sensor sees the black line, "THEN" set motor A speed to 4.
The YES/NO command is essential in programming. I can't stress that enough. Your kids MUST learn how it is used and learn it early. This is where the robot does it's thinking. Often the command is looped, such as, the program goes through a yes/no statement... does something... and the program is then re-directed to go back through the yes/no. It might be looped a pre-determined number of times or it might loop until a switch is depressed or some other signal is received from a switch, a light sensor or the rotation sensor.
I am not sitting in front of the programming software... I'm telling you all of this from memory(and I'm feeling old right at this moment!). I THINK it is called the "YES/NO" command. Get your son to look for it and start trying things out. Then he will be better prepared to help your team.
An adult mentor is also helpful if you know someone that can come over for a short discussion with the kids. They will see anyone you bring over as an authority figure... a teacher or professional, and be more apt to listen.
Sounds like you've got things under control. I'm a bit long winded. I do enjoy talking about this stuff.
I hope I get a chance to meet you in the comming tournaments!

During development we use the batteries until they show signs of slowing the robot down or interfereing with the program. During practice we fine tune and only use fresh batteries. We change after 2 or 3 rounds. During tournament we change after 1 or 2 rounds. So how many batteries is up to you and how much run the robot.

Hi, We are a rookie home school team based in Manchester, NH. We are a bit lost on how to proceed. I read the recommend tasks to complete from FLL and they have helped. I am unsure of what needs to be done with the research assignment. It appears that we are to research a city and do a presentation on what we feel could be done to help the community with robotics. This is separate from the missions? I am just a little lost here.

Welcome aboard Vipers,
The presentation is one more way that the kids compete in a tournament. It is considered a very important aspect of FLL and the winning team is usually awarded one of the larger trophies for their efforts.
The presentation is meant to help kids connect the fun of building toys to a real world challenge. It is the scholastic achievement amidst the thrill of lego robots. This year's challenge is themed around the problems most cities face... be it trash removal, transportation, clean water and resources or the repair of major structures. As part of their challenge, teams are to choose a city from the list given (or maybe their own home town), research that city to come up with a list of current day issues(problems), and as a team choose one of those problems that may benefit from a robotic solution... such as a non-manned trash/garbage collection system, or maybe a computerized transportation system for crowed sidewalks... etc.
They spend time brainstorming ways to correct, improve or creatively solve a current-day problem into a working if not off-the-wall solution. They are given a finite amount of time to present their solution to a panel of judges who grade them on content, creativity, overall understanding of the problem, their method of determining a solution and how it is all presented (among other things). It can be very elaborate or it can be very simple. If it looks like it was thrown together at the last minute (which can easily happen in Lego League :-) then points will be awarded accordingly. Posters, banners, models, even skits are sometimes used to present their solution. The sky is the limit. They may do it any way they like. They are only limited on how much time they have for their presentation. Usually two or three minutes. There is usually a short question and answer period by the judging panel and that's it.
This is an overall explanation but you should be careful to read the FLL presentation rules and information to be sure I haven't left anything out or maybe led you astray.
I actually had one of the parents of the kids come in and help put this together with half of the team. We were pressed for time and the programmers were really focused on correcting problems.
That's one thing I will mention. The builders are usually finished before the programmers. At some point the kids need to decided the building is done so that the programmers can solidify their programs and finish the challenges. So you can have builders standing around with their hands in their pockets near the end of the season. These guys can make posters or work on the presentation to keep themselves busy.
I hope this all helps. I'm sure I raised more questions than I answered but feel free to ask more.
Again... WELCOME ABOARD!

- Message by: RoboSquad 11/09/2002 00:59:49 GMT
We are in MA and will attend the MA state tournament on 14 December. Naturally we were asked to contribute some volunteers to help run the tournament. This is difficult for teams that are competing because the people that are most qualified to be judges and referees are busy with their own team. Then there is also the problem of conflict of interest in judging other teams that are competing with your own.
Since the NH and MA tournaments are close together (I don't know what day the NH tournament is on), what about each supplying judges and referees to the other. I could be a referee or judge in NH without conflict of interest and duties, and someone from NH could help in my place at the MA tournament. Of course this won't work if they are on the same day, but maybe if there is a Nashua local tournament as some are talking about.
Anyone think this idea is worth persuing?
- Message by: B.O.B. 11/10/2002 06:10:56 GMT
Yes, that would be a good idea. Try to get judges from other geographic areas that do not have teams in competition at your event. You want judges and officials to be impartial, that's a conflict of interest if they are taken from the same pool of people who are in the competition itself. Have you brought up the conflict of interest with your event organizers? It's not really fair to the teams that are competing to expect them to also provide volunteers, just taking care of their own team is enough to keep them plenty busy.
So yes, try to pull judges/officials from other teams in nearby states.
The other thing you might try is if there are local college students or engineers in your community who would be willing to be judges/officials.

Wisconsin tournaments pull a lot of judge and referee volunteers from the employees of companies sponsoring the tournament. It might also be a neat way to develop a future sponsor if you can find a few people from a local company with a technology focus.
Many of the runners and timers come from a local FIRST robotics high school team. Additional volunteers also come from teams, but these roles are primarily runners, timers, and scorers.

NH State Tournament Unofficial Results, 14 Dec 2002
The first NH State First Lego League was held in Nashua, NH on Saturday, 14 Dec 2002.
This tournament was an absolutely awesome event! The facilities, logistics, organization, volunteers, judging, and turnout were fabulous! The sponsors, BAE SYSTEMS and NHSTE, (NH Society for Technology in Education) held a fantastic tournament all around.
The 44 teams demonstrated excellence in all areas, from the performance of their robots, to whimiscal team uniforms, to unforgettable team names such as the Electric Jelly Donuts, the Boa Constructors, and the Little Green Men. The performance competition began with each team making 3 runs on the tournament tables. The best of the three scores was used to determine entry into playoff rounds for the top 8 teams. Research presentations were made in other rooms to judging panels; technical judging was performed similarly in interactive sessions without formal technical presentations.
Congratulations are due to all of the teams that participated in the event. I was particularly impressed by the enthusiasm and creativity that so clearly dominated all aspects of the tournament. Innovative ideas for team names, costumes, research projects, and robot design ideas were the hallmark of this tournament. Furthermore, the teams exemplified gracious professionalism when the teams which had been eliminated from the performance rounds cheered on those which were still remaining.
Thanks are also due to the tournament organizers, who orchestrated a great tournament! The organization, registration, emcee, referees, judges, facilities, volunteers, and big-screen TVs all made for a top-notch tournament -- definitely the best school-age tournament at any level that I have ever attended.
Now, for the results:
Director's Award - Royal Blue Pride (Weare Middle School)

I'm not certain this is what you are encountering, but I'll take a shot.
When you first run Lego RIS or Robolab they start with some of the slots "locked". For RIS you need to go to the Settings tab and make sure all the boxes are unchecked for the Lock slot item. I can't remember for sure, but I believe Robolab locks both #1 & #2.
In either case you need to disable these locks to be able to load your programs into these slots.
Hope that helps.

There are nine team members--mostly 11 and 12 years old (6th and 7th graders).
We meet afterschool and on Saturday. We are lucky to have community members that help out, document us and bring us snacks.
There is one more meeting this year (2002). We'll take a break for the holidays. In January, we will be working overtime preparing for the competition in early February.

Discussion: How can you make a robot move faster? By: Intelligent Community 01/24/2003 06:15:10 GMT
I was at a practice tournament in Harlem and a team called GWI (Girls With Intelligence) had a robot the zooomed across the field, even though sometimes it was too fast. All of the team members (including me) wanted to know how they were able to make their robot so fast so I posted this message. If GWI comes online or any other team that might know how to make a robot fast, please reply to this message... thank you! :
- Message by: TeknoDevils 01/19/2003 20:32:08 GMT
The simple answer: GEARS.
Many robots have to use gears to connect the motors to
the wheels. If you put the smaller gear on the motor
and the larger gear on the wheel, you make the wheel
turn slower than the motor. If you put the larger gear
on the motor and the smaller on the wheel, the wheel
will turn faster than the motor.
You can also go faster by using a larger wheel. Each time
the wheel goes aroung one, the larger gear will travel
a longer distance (circumferance = pi * diameter).
These ideas can only be taken so far. As you speed up a
robot, its power goes down. If you take this to ridiculus
extremes, you can make a robot that WOULD travel a super-
sonic speeds, but does not even move because the motor(s)
cannot provide enough power.

- Message by: TeknoDevils 12/17/2002 18:50:26 GMT
Yes, you may run programs on your robot while it is in base. The confusing
restriction is that you must press the green run button to start a mission.
The green button is that LAST part of the robot that is allowed to be touched
before the robot LEAVES the base. Pressing the green run button than
touching the robot is not allowed. Having touched the robot in base, you
MUST press the green run button before having the robot leave the base again.

Our robot falls apart alot. Do you have any stability tips?
- Message by: Harris 11/01/2002 18:01:22 GMT
The Roverbot in the Lego Mindstorms constructopedia is very sturdy you may want to look at that for guidance.
Basically you need to reinforce the pieces that hold the motor and gears so that it cannot pull apart in any direction.

- Message by: Motor Heads 10/13/2002 16:39:58 GMT
Randy: Thanks! We continue to be confused about the presentation part of the competition. How do the boys show the Judges how many resources they've used? Do they just say "...and we learned about this when we visited...?" Or do they hand the Judges a paper listing their resources? Do your teams use Robolab? We are using it and I feel like we're really behind! We've only just started learning the Inventor part. We haven't even tried to do any of the challenges! Coach Kim
- Message by: B.O.B. 10/14/2002 08:12:41 GMT
Hi Kim,
We're not in OH but we're also homeschoolers, be sure to check out that section of the forums as well.
The format for the presentation really depends upon how the boys would like to present their material. What they will want to do is get across what they learned in a short period of time. The judges do ask questions once the teams have done their presentation.
Our team always puts together a team notebook and will include in that book any references we used. For example, we might print out an article from a website, clip a newpaper article. If they used books from the library, they could include a list of those books in the notebook. We also include our team logs (notes from each meeting) and pictures that we have taken of the team as they work on the challenge.
We used Robolab last year. Our main programmer had a Mac, so RIS was not an option. We haven't decided this year which one we will be using. Robolab is a bit harder when you first start out then when you use RIS. But once you get used to it, it gives you a lot of control over your robot. What seems to work best is learn by doing. Go ahead and try the challenges.
I run a robotics list:
http://www.jsoft.com/archive/robotics/
One of our list members who has an FLL team up in Michigan has a nice tutorial on Robolab at his site:

this was posted over the Programming section of the forums:

During the sign up period, you could sign up for any tournament in any state. First choice for a given state is for in state teams, but there are no restrictions on which state you are trying to attend. You just have to abide by their rules (some states require qualification in a regional first). Since registration is closed, I would contact FLL to find out if there are any openings left.

You could test a little better if you got a infrared remote. It helps a whole lot, and you don't have to keep getting download information from the computer. It doesn't go far, and can't be used for a substitute of programming. Only good to help you test the mechanisms when you first build them, but, it still helps. It comes with the Ultimate Accessory Kit, which usually runs about 40-50 bucks, if you're mentor doesn't mind buying it. Hope it helps. There's a picture of it, also.

Discussion: Technical interview By: Obsidian Wolves 12/18/2002 09:19:41 GMT
What is the format of the technical interview? Is it a formal presentation? Or is it an informal question and answer session? What types of information should the students expect to present?
Kirk Beckendorf
- Message by: TeknoDevils 12/18/2002 02:49:33 GMT
This is normaly not a formal presentation, but can vary from
tournament. The team should be prepared to present an
overview of the hardware and software. What are the strong
points what still needs work, why they picked to go some
direction. For software, it is very helpful to have printed
copies. For hardware and software a 'cheat' sheet with the
highlights on it can be very helpful when the team goes
silent for those truly nasty open ended questions like
"Why is your robot the best?". Just be very careful not
to answer, or even prompt the team. In fact, the judges like
to see the team come in without the coach. This forces the
team to think for themselves and not do a head swivel looking to you for help you can't give!
I just saw this was under Oregon. I have no specifics to
offer you as to this tourney, only the above generals.

Your generals are right on target.
Specifically, at the 12/7 play-off tournament, the technical interview was done at a 'practice' table setup in the school library. The judges asked the team to demonstrate each of their missions and talk about them, the robot, and the programming. Some side conversations between an individual team member and a judge also occurred. I'm guessing this was to make sure that everyone on the team had a chance to participate.
We have a big team (10 kids) and I heard afterward that it was hard to hear the judges, but that there were no questions they felt were too tough.

See the handbook at home.attbi.com/~pssweeney
It has some information on the interviews.
They are called interviews because the team does not HAVE
to have a formal presentation. If the kids have nothing to
present, the judges will ask the questions. The top teams
will have a 'presentation' ready. This would be a cheat
sheet of the good, bad and ugly about their robot and software that they can talk to or it might be a poster.
The big thing is to flow with what the judges want to do!
The team needs to cue from them.

- Message by: Harris 10/20/2002 06:27:40 GMT
Here's section 12 of the rules, I think that answers your question.
12) RETRIEVALS: Points for an object retrieved back to Base are only awarded when some portion of the object itself crosses the Base line, whether or not the robot crosses too. If the team touches a robot which is in control of a retrievable object before some portion of the object itself crosses the Base line, no points are awarded for the retrieval, and the object will be kept off the field by the referee. This is true even when there is no Robot Return Penalty. The team may unload successfully retrieved objects in Base by hand.

I'm not sure what it might be related to. I suspect it might be happening when the machine goes into standby mode. I'm more concerned with the fact that I can't kill the process. Other things (windows explorer, dos prompt, etc) on the laptop still work, just not Robolab. When I try to kill it via Task manager or with a program I have called Process Viewer, I get an error saying (something like) "The program cannot be stopped because it is being debugged".
If it locks up and I can recover, I could live with that.
- Message by: TeknoDevils 10/31/2002 15:27:59 GMT

Hello, I am the team programer. We have an XP system and after leaving the computer for awhile then starting up Robolab 2.5.1(which we have already used a patch on), opening a program, and trying to Download it to the RCX, Robolab locks up! I am able to restart the computer, but a sign some times pops up, it says "ENDING PROGRAM PLEASE WAIT, if you end the program now you may lose any unsaved data". If I wait as the message says the computer stops restarting and if I try to restart again the whole computer locks up! If I hit the "END NOW" button that pops up very very quickly (usually it loads too fast!) it does the same thing! When I hit the power button twice (once to shut down again to start up) and enter Robolab, and open a program, and Download it, it works:) So anytime we open any other programs, like email, RoboLab locks up. We are restarting the computer at least once a day. I don't know why Robolab keeps locking up? Can anyone help me?

- Message by: RoboSquad 09/25/2002 14:27:12 GMT
A "container" is the name RoboLab uses for what the rest of the computing world calls a "variable". You don't need to use variables to follow lines, depending on your algorithm. However, now we're getting away from basic software useage to how to solve specific challanges. This is best left for each team to figure out themselves.

I respectfully disagree with your statement that we are moving away from basic ideas to the challenge. It is my understanding that FLL is all about cooperation and learning as a team. If my team learns how to write a solid line following program, they will have learned something useful in many situations. And if another team helps us learn, then they are spreading the FLL spirit.

There is a sample program(s) included with your Mindstorm kit that go along with the Lego mat and Lego manual in the box. The light sensor is a two part device, a light emitting diode and a light receiver. It works by shining a light and looking at how much is reflected into the receiver. On the black part of the game mat very little is reflected but on the white most of the light is reflected back. Students should become very familiar with changing the programming on the light sensor since there is a lot of light at competitions. If you take a look at the program block you can see there is a way to set the "ON" point and the "off" point. The default is 20 units between the two but you can change this value to suit conditions.
If you follow the programming that follows the black line on the Lego mat, the robot just turns one direction until the light changes, and then turns the other direction until the light changes. The effect is the robot wobbles left to right as it follows the edge of the line. The variable is what side of the line the sensor is programmed to follow and which side of the robot the sensor is on.
Hope this helps.
Good Luck All,

If you are using the RIS program. You will find a line follower in the examples (library / sample programs / roverbot / line follower). That is a good example of a basic line follower. You will have to adapt it for your particular robot and when to use it and when not to. From this example you can think about alternatives to turning on and off, is light and dark all there is?, how many light sensors are you using?. Be creative.

These are the kinds of things your team needs to figure out. Basic line following is easy. Good line following takes some cleverness. This is one of the things that differentiates between winners and runners-up.
When the line following doesn't work right, figure out WHY. You will have to do lots of experiments.

If you are using RIS 2.0 here is a sample program in english that you can convert to graphical:
set VLight = 50
set VCount = 0
Set VCount = 100
Reset rotation2
Repeat
if light1 > Vlight then
Motor 1 on
Motor 3 off
else
Motor 1 off
Motor 3 on
end if
until rotation2 > Vrotation
Motor 1 & 3 off
This will follow the left side of the line with a light sensor on port 1 and a rotation sensor on port 2. If you want to use time instead of rotation, replace rotation2 with timer1 in both the reset and until.
Once this works you can place the reset to motor off inside a myblock and reuse it where needed. This is the basic on off line follower that is provided in the example code. You can work on this and start improving on this basic concept. Some things to think about: There are two ways to stop the motor (braked, float). What else can you do other than stop the motor? How can you follow a branch in the line?

Are you using a retail version of the lego mindstorms? If so go to the training missions. There are 2 missions that are relevant. the 1st one is the touch and light sensor mission (either the last or 2nd to last regular mission) and then 1 of the extended chalenge missions covers line following specifically.
- Message by: Eco-Nuts 10/18/2002 22:51:19 GMT
Please be more specific. The more specific you are about a problem the better we can help you. Now in general if you are using the RIS programming all of the decision blocks will ask you which sensor to use, select the light sensor and then set either > x value or < y value where x value is for light and y value is for dark (white or black line). Once you have programmed the RCX for a light sensor on a specific input port and run the program once. You can then use the view button to scroll through all the ports and find the port your light sensor is on. Hold the sensor over the white and see what the value is and hold it over the black line and see what the value is. There should be enough difference between the values to determine whether the sensor is over the black line or not. Use a decision block and set the light value somewhere between the two. Now you have two paths, one for what to do when the sensor is over white and one when the sensor is over black. Now all you have to do is decide what to do for each case and place a repeat around the decision block to make the decision happen lot's of times. Use a Repeat until or Repeat while and use something like time or the rotation sensor to know when to stop following the line. Remember to stop after the repeat so the robot will stop there and not continue in a circle.

Are you using the blue sensor watchers that are positioned horizontally from the program title block?
Don't use them - there is no way to turn them off!
The blue sensor watchers are not useful in FLL.
You have to use another method!
Line following is not as easy as you have it set up if you are using the blue sensor watcher.
The sensor watcher has its own built-in loops, tests, etc. Without the sensor watcher, you have to set up your own loops and tests to exit the loops.

The light sensor can vary readings every time you work with the robot. You should put the upper and lower limit into variables say maybe Dark and Lite (note light is a reserve word so you can not use it). Then place you robot over the white press the view button until the correct sensor port has a ^ pointing to it. make a note of the reading. then move the robot over the black line so the sensor is completely on the black. Make note of that reading.
Then in your program set the lower limit (say Dark) to the value of the sensor over the black line. (Actually I add 1 or 2 to this value) Set the upper limit (say Lite) to the reading of the white (Actually I subtract 1 or 2 from this reading )
You will need to do this each time you work with the robot because the ambient light in the room will change.
As far as rotation sensor we are not using it in our first competition because we can not figure out how to attach it with our roverbot base. But when I worked with it you needed to gear it up. It only measures 1/16 or a rotation. So to decrease the "error" you want to have you wheels move only a tiny bit for 1 revolution of the axle in the sensor.

Hi! our team would like to know if there is a more advanced way of following the black line using one light sensor.We are using RIS 2.0 If you could help us do send us an E-mail!
- Message by: TeknoDevils 09/23/2002 18:01:47 GMT
I am assuming you are using the "shades of gray" algorityhm. This is the method where
you turn one way if the light value is greater than some number. You turn the other way if
the light value is less than a different number. The trouble with this approach is that the
robot tends to hunt alot. It bounces back and forth and makes less forward progress than
it could.
With just one light sensor, it is fairly tough to come up with a better approach. You can make
the current approach work better though!
Try changing the location of the light sensor.
Try moving it closer of farther away from the drive wheels.
Try various ways to turn. Slow a motor, stop a motor, or reverse a motor.
Try adjusting the light and dark values.
Playing with all these numbers will result in following the line faster/slower and sticking with
a sharp curve.
Other algorithms exist for just one light sensor. They tend to require remembering what the
robot is up to. You would need to keep track with a variable if you think you are to the right or
left of the line. A search on the web will find lots of information! Try the Seattle Robotics Society!

Line following is fun. I haven't had a chance to study this year's challange much yet, but the word to the wise is to avoid the "cool technology" when simpler techniques exist. The winning team in Maine last year didn't appear to use any line following at all. They simply had a rock-solid design and an extremely well planned "canned" routine. They did do some clever "smart alignment" by using their touch sensor, though.
The line-following task is still worth using to get a newish team to understand the intricacies and tradeoffs in h/w and s/w design and implementation. But always look for the simple way, even if it's not the absolutely most elegant.
That said, FLL will have slipped a task in that simply begs for line following as the optimal solution...

We haven't tried it yet but it seems like the line following problem could be conquered with the use of one light sensor and the rotation sensor to form a sort of crude ID (proportional, integral, derivative) controller. You could provide negative feedback by slowing one motor proportionally as a function of the error from mid scale "gray",(the sensor would be on the edge of the black line) how fast the error is changing, derivative, and the summation of the error, integral. There must be routine out there somewhere written by a ego leek that the kids could leverage. While the control engineering behind this can be analyzed to death, picking the "tuning parameters" for a ID controller can be treated as a trial and error exercise that demonstrates the magic of negative feedback.
Of course it helps if your mechanical design doesn't drift. The Team Manual stresses the importance of making use of the differential so one motor will be the primary drive for two wheels. We've performed the experiment demonstrating how difficult it is for two wheels to spin at the same speed using two motors versus one. The kids now understand that the differential can make things easier. We've also done experiments demonstrating the trade off between torque and speed. Too bad this stuff wasn't around when I was a kid; we're having a blast. Everything we've built has been temporary, but when we've got the concepts down, I'm hoping our designers and programmers will be able to "put it all together" and come up with something clever.

Hi Dave,
My guys are 8,10,10, and 11. At least two of them are gifted individuals. It's not likely we'll find PID code they can use. I wouldn't expect them to develop it, but using cannned code found on the Web would be fair game if they understood the concepts. My guys are programming for the first time as well. The guidance I've given them is to use a "top down" approach. That is, they put the RCX in "View" mode and see what they need by pushing a training bot in a mock run of a "mission". Then they write English language pseudocode of what the bot must do --- ie go x number of rotations, look for line then turn ... etc. Then they string the code together. Invevitably the code doesn't work. Then the team and I discuss what went wrong. We do talk about when the robot is running "open loop" (nothing guiding it) and when it is running under feedback control "examining light sensor and deciding". The kids came up with some really insightful ideas. Are you implying that by exposing the team to engineering concepts that I am guiding the team too much? The construction team has decided to build a bot right out of a book and design add on tools. Is the "book" providing too much guidance? Frankly I like the engineering decision to leverage stuff known to work and customize accordingly. Would a can of PID code known to work be illegal? Is it too much guidance to hook up the output ports to a scope and show how the motors are pulse width modulated to achieve the various speed settings? Is it too much guidance to discuss basic programming constructs. The modular tool idea came from the kids, but if I suggested that was a possibility, I don't think that would be too much guidance. I could let them try to figure out how to gang up the sensors, or advise them that if you hook a touch sensor to a light sensor port and treat 100 as a "touch" you can use all the sensors. We haven't gotten that far, but I feel completely justified in cluing them in about this "trick" since they only have a rudimentary understanding of electronics. They get theory from me and the articles I provide. The implementation is theirs.

The spirit of FLL is, AFAIK, different from competitions like Odyssey of the Mind or Destination Imagination. In OM and DI, adult coaches and parents sign a covenant that precludes their doing anything for the team other than driving them to their destinations and supervising the use of sharp objects.
The FLL spirit still wants the kids to discover, but I think it recognizes that most coaches of a LEGO Robotics team have a good deal of kid in themselves. FLL also encourages the use of discipline-specific mentors in all aspects of the challenge.
So treat it a lot like a "real" sporting team might: the coach isn't out on the field making plays, but does try to instill and inspire the players with his/her insights and experience. If you use someone else's work just to "win" the challenge, that's probably not "fair". But if you point out the work and the kids decide to do their own rendition of it, that's cool. Ultimately the judges can usually tell when a coach has done "too much"; it will show in comments like, "the coach said we should do it that way..." instead of, "the coach told us about this algorithm; we looked it up and did it this way, with these tradeoffs..."
So just like following the black line, the hard part is handling the gray areas well. The best thing is to keep a team memory for next year, so the answer to "how did you do this?" is more along the lines of, "last year we did it this way; this year, we learned and fixed it..."

Jim - Please don't take my comments the wrong way. I am very impressed by what you are trying to teach your kids and would like to be able to accomplish similar things. I was just intimidated by the level of sophisitication you were describing in your post. I really like the "top down" idea for simulating the mission steps. We'll have to try that this week! Thanks for great posts and a great idea.

Thanks Dave,
My mistake that I sort of presumed that the coaches were all engineers and/ or computer science geeks. Sorry I was so defensive, no offense taken by your original post.
Regarding ideas and concepts; the concept that is hard to know if the kids "get it" is the idea of the "floating" (yellow stop sign) output. While floating the output is crystal clear to an EE I sort of wish the ROBOLAB people used the term "disconnect" to eliminate the confusion between outputs "STOP" (really programmed to zero) and floating. The scope was useful for this, but I'm not sure it stuck in their minds. One more discussion of what a circuit is, might help, but it is hard to really know how much the kids take away without getting bogged down.
For now I suppose it is sufficient for them to know that a motor connected to a floated output just "drags" along and spins if rotated (by another motor).
Good luck debugging.
Regards,
Jim

I think FLL is first and foremost about learning, and I see my primary role as a teacher. These kids are new to programming, so you can't expect them to re-invent normal programming practices in a few weeks when they are 12 years old.
An FLL team is a just that, a team. The coach is a part of the team too, but with a different role than the "players". We've had a lot of Socratic discussions about things like line following. Sometimes these wander into physics or other science topics that are not directly relevant to FLL, but become great opportunities for learning useful things. These don't make progress towards the FLL tasks, but I don't mind at all because the kids are learning useful stuff.
The kids on my team are just getting acquainted with algebra in school. As an example we had a long discussion about what the "formula" or "recipe" is for finding the average of two numbers. They know how to find the average of two specific numbers, but haven't yet learned to think in abstract variables. Another example was finding a number within a range by using binary search. This actually came up because motor power 1 was too low and they wanted to try 2, then 3, etc, until they found the right power level. This would certainly have worked and been quicker in the end, but I challanged them to come up with a general method that would be quicker on average. "What if there were 100 power levels instead of 8?"
You can't expect the kids to come up with all the programming concepts on their own. I think it's OK for a coach to guide them into "discovering" a good way of doing something. Sometimes you do have to outright tell them something too. There is such a thing a new knowledge. Not everything can be derived from what you already know.

Hi, The line follow program can be written using one light sensor for a vehicle driven by 2 motors. I challenge my kids to see if they can figure out a solution using 10 icons or less. This is a simple line follow program but it will follow the line. We use Robolab. I haven't tried the same process using RIS but it seems workable.

There is (or should be) a white loose leaf binder with a "CitySights" cover page. It comes with some useful info and room for you to add stuff - like eratta or tips - from the web or your own team notes.
It was in the top of our box with LEGO pieces; if you didn't get one, it's a must for a rookie team, so call FIRST/Pitsco (one may end up referring you to the other, but start with FIRST first). The main number is the same as the one for Scott Evans in my earlier note.

The most important thing to do is to look at the 2002 Team Manual that should have come with your challenge-specific LEGO parts and the challenge mat. If you didn't get one, get on the horn to Pitsco (assuming you are a North American team and that's why you posted here) or to whomever you got your kit from.
In the tabbed section labled Challenge Prep on page 38 you'll see a paragraph headed by Differential and there's also a reference to the Constructopedia.
Further back, in the Appendixes tabbed section, Appendix B has a nice set of engineering terms, and Appendix C has a beams and gears guide. Handy stuff.
- Message by: ACES 10/19/2002 01:18:11 GMT
Ok now you peak my interest. I did get the manual out and looked on page 38 and saw the definition of differential and I understand the concept. The other guy posted a link that gives a good illustration of adding one to a robot (without motors) and why it would be used.
The Manual page 38 says This is very useful for making a propulsion system using only one motor leaving 2 motors free for other robotic functions. I do not see how!!!!!
I have looked on the web about 1 motor drive systems and the only thing I have seen is one that uses a differential and a ratch so that both wheels turn together forward but one stops while the other turns going backwards. What good is that. (sorry engineer types I am more on the programming end).
As I see it you would still need another motor to control direction. While the differential would allow 1 motor to turn both wheel it will not allow steering. As described in that other guys link it may also be useful to get a more accuracy measure of distance travel.
Am I missing something? (With only 5 more meetings before our 1st competition and my team only has a base do we need to rethink our design?)
- Message by: TeknoDevils 10/19/2002 01:40:46 GMT
I do not think you are missing anything at all. You can get
a VERY crude robot with only one motor. It will move forward
and will turn only one way in reverse. I suppose you could
do the challenge, but it is not that practical.
Every FLL robot I have seen uses two motors for locomotion and (if needed ) one for some kind of manipulator.
In my opinion, with only five meetings left, you need to
pick a platform and stick with it! On my team I impose an
arbitrary design freeze date 4 weeks before competition. This gives the S/W team a chance to write code. Of course
we do make changes but they tend to be small.

Hello all,
If you want to follow a line with one sensor and do it with great percision you can try this. If you set up the program to measure the width of the line left to right or flip flop with time or rotation sensors you then can go directly back to the center of the black line after the sensor reads white; then go forward till white is read again. This works pretty good and you get a lot of forward motion. Also, you can have a counter added to keep track of the last turn you made and do the opposite based off the counters incerment value. This variable style is the most accurate and will handle unexpected cases.

Problem with saving programs that have time values < .05.
RIS 2.0
If we have a line follow program where we do
if light sensor = dark
right .01
else
left .01
we can save it and work with it (download, run, modify) as long as we leave the original program open. If we close that program and then reopen it we can not modify it at all. We can still download it but just not change any of the values.
I called lego the tech guy thought at first it was drivers or hard drive. The finally he mentioned the .01 and suggested using .02 but that does not work with anything < .05 and .05 is still too jerky.
Is anyone else having this?
Also I thought about setting a variable and have it use the variable but it automaticly multiples the value by 10 in the lsc file.
I am going to check the lego mindstorm site for any info as well

- Message by: Eco-Nuts 11/04/2002 16:57:45 GMT
myblocks work perfectly well. We use them with everything. The one thing to watch out is that a cange to the myblock will not be picked up by all your programs and will have to be updated in each. This is where the problem with loading from the pull down menu comes from. If you load a program that has the same myblock as what is in the menue but is different, then it will ask for you to rename the myblock before loading. This is good and bad. Sometimes it may be just a space or something else that is not a "coding" change. However, it also forces a check each time a program is loaded. When you load from the vault and not the pull down menu, this check is bypassed and two different myblocks can exist without warning. Only one myblock definition will remain in your program though. You can verify this by looking at the stored file with a text editor.
As for other problems with the graphical environment, we found it necessary to occasionally remove all the myblocks by selecting new from the menue and putting all the myblocks in the trash can. After that we went out of RIS and then back in, reloaded the myblocks from a single program that did nothing but hold the "gold" or blessed myblocks. When you opened each myblock from this program a copy was placed in the menues. After all the myblocs were updated, each program was loaded to verify that each program matched the "gold" myblocks. This process though combersum ensured that we had a consistent set of myblocks in each program. This year we are using the mindscripts which allows for the definition of macros (myblocks in graphical) to be held in an included file. This ensures each program is using a consistant definition.

Part of the problem is the fact that we are moving program files between several machines. There is a MBfile.ini that somehow holds part of the myblock code as well as the .lsc file. I at first did not copy this file.

If you know are using the vault, the default directoy is:
c:\program files\LEGO MINDSTORMS\RIS2.0\users\"user name"\vault\
Here you will find your programs along with a MBFile.ini
One thing you can try is to delete this file, go back into RIS and load your program, go to the first myblock in the program and open it up for rename, click ok and all the myblocks in that program will repopulate the myblock menu. We have found that often we had to do this so we created a single file that contained all the myblocks we were going to use and at the start of a programming day we would delete all the myblocks from the menu either manually or deleting the file. Then we would open the saved program with all the myblocks in and repopulate the myblock menu. This has prevented all sorts of errors in the past for us.

I am assuming that your light sensors are on each side
of the line. If that is the case, your good condition is
when both right and left sensors report high numbers
(white). If the right sensor starts to see black, you must
turn right and when the left sensor sees black you must
turn left.
Do you have the proper modifiers attached to the light
sensor If-blocks? Do you have the right values programed
for light and dark? Are you turning the right way? Does
your robot bounce from edge to edge and not go anywhere?
Does it follow the line and then leave it? Are you willing
to post your code for others to look at and comment on?
Have you placed beeps inside the code to figure out what
path it might be taking? Have you tried holding the bot
wheels just off the ground and slowing moving it from side
to side to see what the software is doing? Have you tried
working with a partner to get other ideas to try?

Marie, if you have a problem in a part of a large program, you can sometimes add a beep to see if that part of the program is running or runs as expected.
A simple example in some form of psuedo-code . . .
If light sensor is > 40
Then 'go forward'
Else 'stop all motors'
might be debugged
If light sensor is > 40
Then 'go forward'
Else 'beep' and 'stop all motors'
A 'beep' sound in the second program should indicate that the 'stop all motors' condition of light sensor less than or equal to 40 was met.

Sometimes 1 second waits can also be useful. We do this a lot to see the separate logic sections kick in during line following. Even if you don't have a bug, it can help the kids understand what is actually going on.

I have used more of a "hands off" approach with my team. I am a science teacher: our team is an after-school program. I would like some further training, but I believe that the discovery method is also the best. We are using "advisors" from previous teams who are earning community service credit for the First Robotics group at our High School, but I do not actually do any of the programming, building, etc. Nor will I allow any of the senior advisors to do it. It's not about winning for us, but the process of learning.

I agree with your approach for the most part. I tried doing that the first few seasons. I'm now doing more direct instruction for both programming and building. I teach a set of skills, try to guide, but expect the kids to develop and troubleshoot their own solutions. The direct instruction seems to be making it more rewarding for the kids.
- Message by: ilsgreen 11/20/2002 20:16:15 GMT
After three years of coaching, I still find myself weighing each teaching opportunity through the year to decide if an Edisonian experimental approach or a direct approach is best for my team's educational growth.
The direct approach seems better when the team members are initially clueless. It's tough to create a good experimental plan or to troubleshoot when team members still need to learn basics in building structures, putting gears together, and programming - and they don't always get it on the first pass. A framework of learning and repitition is often needed to become skilled in the arts needed for FLL. Many first year members really lean heavily on constructopedia models to get started because a step-by-step assembly method is needed for their understanding, even if I did spend time teaching more advanced structures at the beginning of the season. As for programming, I needed direct information when I learned my first programming language, so I'm going to bet that rookie team members need pretty specific direction, too! I also have team members who really need small concrete directives through the season to stay productive because they all haven't learned how to work and think independently - yet!
However, doing too much direct teaching leads to no discovery, minimal team ownership, minimal teamwork development, and no real long lasting learning or excitement about science and technology. Furthermore, the "competition" environment strives towards -- and generally succeeds at -- grading the process of how team members hypothesized problems, thought through and developed solutions, developed as individuals, and worked together as a team.
Some other odd things I'll do with team members are:
- Answer questions with questions or offer indirect answers. Maybe its time for the team member to think on their feet a little more.
- Derail linear thinking of team members - instead of the one way you are doing something, can you think of four or five other ways? Which approach might work best and why?
- Continually remind that this isn't "beating the other guy." This is developing as individuals and as a team to pu forth the best effort possible.
- Group self-analysis or planning - what's working, what could be better, in what ways could it be done, what criteria would decide the best course of action, then determine the action plan.
I liken the team member development side of FLL to marble sculpture. It's sometimes a few chips off at a time to develop team members. Finding the appropriate tool to shape the sculpture is part of the fun and challenge of coaching.

Light Sensor placement Important to line following
Rookie team here. We are in the middle Of rebuilding our robot. So last Friday I had off and so I fooled around with some ideas to present to our team. Anyhow I found out that light sensor placement is very important. Sweeney's hand book talks about not having the sensor to high. (I already knew this from experience) BUT what I found out was how important placement of the sensor from the vertical axis is. (I am probably not using the correct term - what I mean is if you spin your robot ie 1 motor forward 1 motor backward the point your robot spins around.) If you have you sensor close to this point your robot will tend to make BIG turns in order to try to stay on the line. Basically it is overcorrecting on each turn. (in fooling with some designs I 1st thought it was because I had the BIG wheels) I had changed from a roverbot design with the sensor on the front (which could follow the line quite well) to a design with the drive wheels up front and a caster on the back. This moved my sensor from about 2 inches from the center point to maybe 1/2 an inch. I basically had to stick it on a little arm out front to be able to get the new robot to follow the line. I know there is some kind of mathematical explanation probably relating to the turn being in proportion to the Radius square or something like that.
Just thought I would share that in case some other newbie team was struggling with the issue.
BTW I did present my ideas to the builders on my team and they ended up coming up with a better design.

Playing with the placement of the light sensor is an excellent exercise for a team
working on line-following algorithms. A good resource for plans for robots with adjustable
light sensor placements can be found at the URL below, from Gus Jansson's web

of the "WORKSHOP 3D Lego RCX Challenge" for a number of years. Any of his
adjustable sensor robots is a good teaching tool for line following. The URL below

The other reason to make the switch to Robolab 2.5 is to use a USB tower instead of the serial port tower. I have older serial port towers or serial port wires that are somewhat unreliable, so I was happy to switch to 2.5 and USB towers this year.

I haven't done this yet myself; they claim RoboLab will work much better in Classic than in native, but in theory it will run native. Were they using 10.1.x or 10.2.x? Dunno', and that can be a huge difference since there are lot's of USB fixes in 10.2.x.

Motors in a Mindstorms kit are rarely "matched". If you have the luxury of more than one Mindstorms kit, have the kids run tests to find motors that are as closely balanced as possible.
As newsearles noted, a differential is a great way around this. But beware of just "adding friction" to one side, since this breaks the rules of robustness and predictability, since time itself can change the friction properties of your implementation.

I found trying to match all the motors rather difficult. Instead our team tried a limited slip differential which is mentioned in this thread somwhere.

I hope i helped some peoples questions.

The other posters are not incorrect, and their advice is good. However, consider that you will
i never
get all the bias out of the system. This is absolutely true of cars, planes, etc. They all drift somewhat to one side or another. You have to deal with this. The classic way of dealing with it for cars and planes is to give them drivers. The drivers correct for drift. For robots (or auto-pilots in airplanes) you need sensors.
It is relatively easy to make a robot go straight, if it does not have to turn. It is easy to make it turn. But it is not easy to do both. Many teams learn this every year. Solve it, and you will be successful.

Mark Beitz, Coach
- Message by: Urban Lego Heads 10/06/2002 00:40:01 GMT
To all,
As you know by now, the motors are rarely matched due to production differences at the factory. Other factors to check for are loose or ill fitting wires between the motor and the RCX. You will find that motors will even out after a couple of weeks of use. (On new motors) On the small surface of our competition table there are things that can effect the way robots run.
If the table is not level or the subsurface is bowed the robot will track to one side. You can supply different values to the motor power command to help match the motors. Most motors run different speeds between forward and reverse so just changing the motors from side to side may help. Robots with low friction wheels on the front will be more likely to drift than medium friction wheels. (or if using a grocery cart front wheel system, some friction in the pivot will help.) Finally, gear ratio helps. Using the 8T (t=tooth) gear to a 24T or 40T will reduce the speed difference by the gear ratio. i.e. an 8T gear on the motor, coupled to a 24T gear on the drive wheel will have a 3:1 gear ratio and the output speed (and any speed difference) of the motor will be divided by 3. Additionally, the motor torque is multiplied by 3 making friction in the drive system not as critical not to mention an increase in battery life.
Hope this helps some.
Good Luck All

I'm not sure I agree with your statement that changing the gear ratio will change the difference in motors. It seems to me that if one motor is 2% faster than the other, it will remain that way after gearing up or down. What is the engineering principle used here?
I do agree that by changing torque you do change the effect of friction on the system.
- Message by: Bremen Botz! 10/08/2002 00:10:55 GMT
One of the tricks we have used to match motors (if you have the luxury of extra motors) is to place a 24tooth gear on each motor. Apply power to both motors (in opposite directions). Mesh the gears. If the motors want to move, then they are not the same speed. If the tend to stay in place, then they are very close.
This still doesn't mean they will run the same speed on the robot for all the reasons already listed. Remember that the battery level may impact this as well...
It is better to try and correct using sensors and such...

Other mechanical improvements which may improve (but not completely solve!) straightness are below. Sometimes improvements are in the details . . . .
- Do your wheels tilt? Do they tilt differently each time you move the robot? This is an easy way to lose straightness, and some robot designs are very prone to tilited wheels or treads.
- How sturdy is your frame? Does the frame keep the wheels of treads from wobbling?
- Which wheels are you using? The large, soft, "motorcycle" wheels did not always sit the same way with the same tilt on my team's 2001 robot. Treads and the harder wheels tend to sit on a table more relaibly.
- Can you incorporate the differential gear to try to transfer some power from one motor train to the other?
The use of sensors, motor power changes, addition of friction, and lower gear ratios mentioned above are also effective ways to help straightness.

I dont understand. Why dont you simply switch the motor leads, as you already know?
Are you using RIS? RIS doesnt define a direction as forward or backwards. It simply shows a graphic with the motor direction as up or down. It is up to you to define if up is fwd or backward.
In RIS, you can make myblocks for FWD, and within the myblock you can set the proper motor direction to provide forward robot motion.
Once you have several myblocks created (one for FWD, one for TurnRight, etc), you no longer have to be concerned about motor direction - that is hidden within myblocks!
- Message by: Eco-Nuts 11/27/2002 17:14:07 GMT
We set the direction for forward in a setup block only once. We also set the speed of the motors. From here on out we assume that on will go forward at high speed. If any myblock is used that changes this condition, then it changes it back before ending the myblock. To go backward we use:
Reverse A C
Power A C 4
On A C
Wait x
Off A C
Reverse A C
Power A C 8
This way outside the myblock, the direction is always forward and at high speed. This allows the direction to be set once in the setup and not worry about physical direction commands goofing things up. I beleive there are similar structures in Robolab.

Debugs, you can change motor direction in your program instead of reversing the leads. Small arrows on blocks in RIS. Arrow direction in Robolab. If you have to, take one sheet of paper and chart which motor direction is forward, then refer to it for the rest of your programming. Sometimes forward ends up being to the left or pointing down - lots of teams work through this.

Discussion: Size of programs By: KnightMare 12/14/2002 07:23:43 GMT
The RCX can store 5 separate programs. What is the size limit of each program? Is each opcode one byte? Are there any tools available to determine the size of a Robolab or RIS program? I understand that RIS programs are stored in Mindscript format. What about Robolab, can one just look at the size of the robolab file to determine how many bytes in the RCX it will occupy? Last year we created a long sequencial program and we ran into a problem which I believe was due to the program being at the size limit.
- Message by: SharonA 10/04/2002 20:08:43 GMT
There is a way to determine the precise size of the program, but it requires other tools and knowledge. However, the limit will probably not be approached in FLL work unless there is some really wasteful and inefficient coding going on.
One thing to note is that there isn't a fixed space for "each" program, but one space shared by all.
--Jack Gregory
- Message by: Eco-Nuts 10/04/2002 21:54:31 GMT
One problem that you may have encountered is that there is a limit to the number of blocks that can be sequenced together. This is not a limit of the RCX but a limit on the programming environment. You have to get creative to get around that. We used a variable watch to wait for a variable to get a certain value and that allowed the rest of the code to execute. I suspect that this slowed up the processing as the RCX now had to manage multitasking to continue to look for the variable but this did get us over that limit. We had to do this in 2 of our programs and still did not run out of memory (our 12 year old programmer came up with the solution).

I highly recommend using RoboLab for programming. It is much more flexible and we have never run into these types of problems.
- Message by: Eco-Nuts 10/04/2002 22:45:04 GMT
Flexibility is in the eye of the beholder. This has been discussed in other sections about the merits of RIS vs Robolab. The only things that Robolab have are subroutines (RIS uses inline myblocks in place of subroutines) and some data recording & displaying that data which is not useful for FLL. Bottom line each programming environment has it's quirks and it is a personal preference to which one to use. Neither one is better than the other and both do the exact same things. There is nothing that you can program in one that you can not do in the other. Since both use the same block constructs with different names neither is more flexible than the other. Again it just matters which one you are more familiar with. Again both do the same thing and one is not better than the other. It's a matter of familiarity and which one you are most comfortable training the kids in. The kids will get the benefit of learning basic programming skills no matter which language you choose. Again future languages are likely to be more graphical and both provide this now. Robolab uses a graphical environment that is already used in control and monitoring in the "real world" via LabView. However, LabView is not generally used as a general programming environment. A good programmer understands the basic programming constructs and uses the programming tool as a tool only. I have learned many programming languages in my time from assembler to ADA and always fall back on the basic constructs. Both environments teach the basic concepts and the kids should be taught the concepts along with the specifics of the language you are using.

Hi Dave,
For the most part I agree with you. I use Robolab most of the time. In my experience with RIS it seemed that the limitations were in 1) the number of icons allowed in one program, and 2) if your program does grow a bit, RIS doesn't allow the whole program to viewed in one screen. A strength I see for Robolab is that you can lay your your thoughts on the page without connecting any icons. When you have mapped out the program the icons can then be connected by wires. I find for teaching students to think through their programming, Robolab is a better teaching tool.
my 2 cents.

Our team gets around that by building a hierarchical structure using the myblocks. We think in higher levels of what needs to be done and assign a myblock to that and then inside the my block we drill down another level of functions using myblocks until we get to the small blocks of code. This is very intuitive for the kids and follows general programming practices used in industry. Once the diagrams are complete we review the resultant code in text form to further understand what we have done and how each text code is represented in the visual diagram. We also add comment blocks to describe what is going on in each myblock. As for space, we also build portions of the program side by side and then connect them back up when they are complete. The zoom in RIS helps with this also.

Most teams will not get into any trouble with filling the program space. I have not found anyone who can give a firm answer on predicting program space or usage. You should suspect that you have run out of space when your students have large programs and recent additions to programs either don't run or are unpredictable. We have heard from informed sources that using "my blocks" (sub-routines) uses less space in memory. There are also some commands that combine functions into one command. (i.e. "On For..." instead of "set power, turn on, wait seconds, turn off") also new teams like to include a little routine to "dance" or play tunes both of which use program space and battery.

I have heard that you can achieve 5 separate programs each for the touch sensor (switch) off and on status. Therefore a total of 10 programs. If this is true how do you program. It might be intuitive that you would also have the switch in the particular state to program. Can anyone confirm this and how to do it.
- Message by: Bremen Botz! 10/10/2002 04:07:59 GMT
We did something similar a couple years ago based on whether the light sensor started on black or white. The same can be done using touch switches. Look under the YES/NO block in the RIS software. (I'm sure someone else can help with Robolab)
Make that the first block in your program, whichever statement is true, that stack will execute...

Some of you have already touched on the fact that there is a limit for the number of blocks in a stack in RIS. Intuituion tells me that if you were to use the YES/NO method you might quickly approach the block limit because even though there are two separate paths of execution it is still in the same stack.
There is a relatively easy way to create multiple stacks (I'll write the example for 3 stacks, main,stack1,stack2).
Assume that you have a RIS program that you want to split into 3 stacks. You want the main stack to run and have it switch to Stack1 at the end, then at the end of Stack2 you want the program to terminate.
At the beginning of the main stack (the one that you normally program in) set variables jmpStack1 = 0 and jmpStack2 = 0. The trick is to create 2 variable sensor watchers. One will watch for jmpStack1 = 1 and the other jmpStack2 = 2.
At the end of the main stack, set jmpStack1 = 1. This will trigger the sensor watcher to run its stack. The first thing you should do in Stack1 is set jmpStack1 = 0 so you don't forget.
At the end of Stack1 set jmpStack2 = 1 and set jmpStack2 = 0 at the top of Stack2.
I've never actually done anything significant with this method, so I don't know the effects on sample time as you add more watchers. I would imagine that the effects would be minimal, but make sure you test it out before doing anything critical.

We have just recently found ourselves dealing with two programming problems and would like to know if anyone might have solutions for us.
1. We were working on a program that included a MYBOT block that a team member had created. The program worked great with the MYBOT. The next day when the file was opened to change some settings, we immediately got a message saying the MYBOT name had to be changed since it matched another
name. Thsi was not true. However, when he tried to change the name, he kept getting a message claiming the name was not valid. Everytime he opened this file, the same thing happened and the system could not exit from this
request. We had to re-boot.
2. Occasionally, when re-opening programs that have been saved, we will not be allowed to adjust the variables on the light sensors. These same programs, which worked the day before, will not be able to be downloaded. We receive an "unrecognized brick error" message.
Any suggestions?

I assume your are talking about RIS and MyBlocks. When you change a MyBlock and that MyBlock is being used by other programs, the software will not let you do that. The MyBlock is not a subroutine that all programs will call. It is inlined programmed and has to be recompiled in each program to be updated. This makes it tough to load one program that uses a MyBlock that already has a MyBlock of that name but is different. I found that you have to remove all the myblocks in the MyBlock selections before loading any programs. We used one program to load the myblocks and then loaded the programs for each slot seperately. Any differences in the MyBlocks showed up as errors. The other way to clear up these problems involves removing the files in the directory you are using and loading only the files containing the programs for each slot in the vault.

Dave - your statements are in quotes:
"When you change a MyBlock and that MyBlock is being used by other programs, the software will not let you do that"
This is not accurate. The whole point of Myblocks is to hide complexity and re-use code. Myblocks can be written in one program and used in others - no problems!
"The MyBlock is not a subroutine that all programs will call."
Yes it is!! All programs can call a Myblock, as long as it is the same user name who signed on to Mindstorms.
"It is inlined programmed and has to be recompiled in each program to be updated."
How the RIS development enviroment handles code is irrelevant, imo. The Myblocks work as desired. Whether they are re-used in the RCX or duplicated doesn't matter. To the programmer, the Myblocks behave as re-usable code.
"This makes it tough to load one program that uses a MyBlock that already has a MyBlock of that name but is different."
Tough? It is impossible!! Two different Myblocks with the same name cannot exist for one Mindstorms programmer!
"I found that you have to remove all the myblocks in the MyBlock selections before loading any programs"
Prior to loading a pgm, you should always exit the programming development screen. NEVER load a program from the drop-down FILE menu.
If you remove all the Myblocks, then the re-usable code is gone! There is no re-usable code to re-use! What good is that? I can see why you dont like them!
I think if your kids try using Myblocks as they were designed, you would be pleasantly surprised by them.
Using reverse logic: without Myblocks, RIS would not support a FLL robot very well!
IMO, the way for the kids to do well on the FLL mission is to have them create 6 or 8 Myblocks, and use those few routines to build ALL the missions.
- Message by: Eco-Nuts 10/23/2002 19:36:51 GMT
It is very easy to get the myblock confused. Write a simple program using one myblock and the save that program. Start a new program and change what is in the myblock. Save that program and reload the first program. You will find that you have to rename the myblock because it is different than what is currently has in memoroy for that myblock. This is due to not being a subroutine. The myblock is defined in each program you use the myblock. Each program is stand alone and one myblock in one program is not related to a myblock with the same name in another program.
Soubroutines would not change from program to program and would be "called" or inlined from a common location. RIS forces each program to be stand alone. Find the location of your programs on the disk and open them with a text editor. You will see the definitions and get a better understanding of how RIS works. This resultant code is Mindscripts and can be modified and downloaded with a mindscripts editor outside of RIS.

Myblocks are NOT defined in each pgm. They are common, shared routines.
If you define a myblock named FWDtoWall in one pgm, and change the myblock in another pgm, the myblock will be changed in BOTH programs!!!

You need to verify what you are saying. Again if you change a myblock it will not be globally changed. TRY IT. What is worse is I used your method of loading a program from the vault and you are correct it did not ask to rename the myblock but when I added the changed myblock to the routine and opend both myblocks the original and the changed myblock appeared. I saved the program and found that the original myblock was the saved one. But this would be very confusing to the kids and I do not recommend that. What the software is acutally doing defining a macro not a soubroutine for each myblock (Use a text file to look at the program's lsc file). Their is a large difference between a macro and a soubroutine. A macro is a short hand notation for a group of commands. A soubroutine is a set of commands that are called from a main program. RIS 2.0 uses macros and not subroutines. The "menue" of myblocks is just a convenient way of transferring a macro from one program to another. The problem like I said is that you want to make sure the macro has not been accedentally changed. One way to make sure of this is to load a set of "gold" myblocks and then load each program from inside RIS 2.0 to verify that each myblock matches the "gold" myblocks. Otherwise you will not know that all your programs are using the correct myblock. You can get away from this problem by programming in mindscript. In mindscript you can load a file that has all the macros defined and then just use the macros in the program without trying to redefine it in each program.

Do your kids pgm in Mindscript? Is there a gui interface like RIS?
I kind of agree with everything that you are saying - kind of.
RIS 2.0 does have several nasty bugs and poor features. One is how the subroutines (or macros) are handled.
Yes it could be alot better; but - it is good enough!
I don't think imo that a team can be successful at these missions without using Myblocks - that is my main point.
Without Myblocks, they end up with long long strings of commands that no one can get their thoughts around.
Myblocks should be used as building blocks to build the challenge solution. They should be solid pieces of code that are perfected BEFORE the actual missions are programmed.
For example, I make sure my kids determine which functions their robot will need, and write those commands PRIOR to starting the missions. For example:
FWD_Distance
Turn_Right
Turn_Left
FWD2Line
FWD2Wall
etc.
Once these MYBLOCK functions are perfected and bullet-proof, the kids grab them and use them to build the actual robot runs.
You are sort of correct with regard to the functioning of Myblock changes.
But, when a Myblock is changed, you can force the same Myblock to change globally, although somewhat manually.
You have to open the Myblock, make the change, then place the new Myblock at the top of the pgm and save the pgm.
The changed myblock will replicate itself to all same-named myblocks below it.
My kids only create and use a half-dozen myblocks, and they generally perfect them early on in the challenge. They are all relatively simple yet powerful functions.
If a Myblock changes substantially, they usually create a new one with a new name for a different purpose.
The key is when changing a Myblock, snap it into the TOP of a pgm so that all lower Myblocks change automatically.
If the changed Myblock is not the first occurence, then the old version seems to come back to life!
- Message by: metro monkeys 10/22/2002 22:14:32 GMT
Mark - I think that both of the problems you are experiencing are easily solvable.
First of all, I want to mention that I wrote a lesson booklet on RIS 2.0 which is available at:
http://www.hightechkids.org/fll/coaching/Training%20Material/classmaterial.htm
If you look at this, it explains the gotchas with Myblocks.
Some of the posts that you received from other posts are wrong and misleading, imho. (Nothing personal, I just disagree with them!)
Myblocks behave as subroutines, they are re-usable, and they can be and are shared between different programs.
It appears to me that whoever signs on to Mindstorms shares all of their myblocks that they created. (If you sign on as a different userX, your programs will only be able to share the userX's myblocks).
So if your kids sign on to Mindstorms as CitySlick, then each Myblock that they create can be used in all their programs.
When "opening" (retrieving) an old program, ALWAYS exit the program development screen one level back. DO NOT use the FILE drop-down menu to OPEN (retrieve) a program. This is when the Myblocks force a rename, when it shouldn't. I think this is the worst bug in RIS, and is a real nasty one.
When this happens, you MUST ctl-alt-delete to avoid causing havoc to your existing Myblocks!!
I cover this and many other gotchas in the booklet.
Your second problem may be one that my kids ran into but I forgot about. It would be a good one to add to the booklet someday.
Lets say that you have a Myblock named "Fwd2Line" in the CitySlick user folder that has a light sensor attached to port 2.
RIS will get upset if that Fwd2Line myblock exists and you start a new program with a touch sensor on port 2. RIS will not allow a touch sensor on the same port as a light sensor (at least it can't know about it!)
Best bet: trash old myblocks as soon as you know they are not needed. Write down which ports have which sensors, and don't deviate from one pgm to another (including myblocks).
Let me know if this helps!

I would recommend not trying to time something that small. The RIS is a multi-threaded environment that may take longer than 10 mil-seconds to respond. From the original example there are ways to achieve a similar function without relying on the timing. Ask yourself what are all the options you have and try each one to see how it works.

- Message by: Eco-Nuts 10/23/2002 20:00:10 GMT
That is the point. Delete the myblocks and have one program that loads the saved myblocks. We call this the "gold" program. That is where the saved myblocks are stored so that accidental changes do not occur. Once the "gold" program is loaded and each myblock is reintroduced into the system. The real programs are loaded one by one and checked against the "gold" myblocks to ensure that none of them has changed. Of if they have changed which version do we want to keep as the "gold" myblock.

If you are trying to get a delta time that small you can probably just leave it out. For example, if you are using it in a line follower for a wait, try just leaving it out and letting the program loop over that set of code as fast as it can.
A^C^
Power AC 8
Repeat Until (some condition)
If light<35 (turn right)
OFF A
ON C
else if light>45 (turn left)
ON A
OFF C
else
ON AC (go straight)
end repeat
Some people put wait commands in this kind of line follower but they are really not needed.

What symptoms do you see to know that the memory limit has been reached?
Are there jumps in your subVI's? (This is a derivative of a Skye Sweeney posted issue)
How long has it been since firmware has been downloaded to the RCX? Yes, it erases all of the loaded programs as well, so you have to reload programs after the firmware. However, I have seen robots show a much better ability to follow all commands after a frimware and program reload, especially when programs are long and have been downloaded to the RCX several times. But I'm not sure if erratic following of commands is a symptom . . .

Some answers to your questions:
About how many icons are in your programs? We have one program with about 150 icons, a second with about 100, and two more with about 50 each.
Do you use both subVIs and the call/run subroutine command? We do use both. We use subVIs for things used once just to make the code cleaner. We also use the subroutine initialization wired to a subVi containing the code for the subroutine. Then use the call/run command for things used multiple times (3 subroutines in 3 programs, none in the other).
What symptoms do you see to know that the memory limit has been reached? It seems to download fine, but then only part of a program will run, or the RCX just stops - basically erratic behavior which reloading the firmware and loading any one of the programs (or all that will fit) will correct. We then go back, rewrite with fewer blocks, and it all works.
Are there jumps in your subVI's? Yes, and this may be a problem. The jumps are inside one of the subroutines though, and because it is a subroutine, we thought it would be isolated from the main code.

First you must understand that a sub-vi is not a true
subroutine. I think you do, but it bears repeating for
those reading! A sub-vi is nothing more than a shorthand.
It allows you to condense on the screen (but not in memory)
a bunch of icons.
Placing a set of red jumps inside a sub-vi
that is called from multiple places in the same program has
'interesting' ramifications. When you get to the first red
jump, which red land do you go to?
If you have a set of jumps inside the definition of a true
subroutine, this should not be a problem.
If you want, you could email me the offending code (in
strict confidence) and I could look at it for you.

First you must understand that a sub-vi is not a true subroutine.
I've seen this definition used many times on this forum and I think perhaps it is a little misleading. The term subroutine does not depend on the location of the code (inline or not). See, for example, the Federal Standard 1037C definition of a subroutine. Indeed, many optimizing compilers place small subroutines inline with the main code for speed advantages.
However, it is important to make some distinction between ROBOLAB SubVI's (which are inlined) and ROBOLAB Subroutines Tasks (which are not inline), since there is no memory advantage to SubVI's.
So, if anyone reading this wants to reduce the size of a ROBOLAB program, use the Subroutine command to define often used sets of instructions. If you are trying to make the program easier to read, SubVI's can often help.

Dennis, these problems seem very similar to problems seen by the team I coached during the 2000 season. They had 3 programs of 240, 240, and 50 icons. We were good for about 3-4 changes and downloads to the RCX before erratic behavior was seen. Reloading the firmware followed by reloading the programs seemed to correct the erratic behavior, but it slowed team progress that year. We didn't try to rewrite for shorter code that year.
There were no subVI's in the code -- I hadn't figured out subVI's to teach them for that year.
I guess I would recommend to keep downloading firmware upon erratic robot behavior for the lack of a better solution.

Discussion: Comparison of Languages By: KnightMare 10/29/2002 20:54:48 GMT
My team will shortly have to decide which programming language we will be using this year. I have used both Robolab (Two years ago) and RIS (last year). I run into various difficulties with each. What I need is a good comaprison of these as well as Mindscript. I understand the user interface for each so I'm not interested in discussions in that area. I need to know the limitations of each language. I've heard that you can do the same thing in each, just that the interface is different. I don't think that is right. In the program size discussion it was suggested that the problem I had last year (a long sequencial RIS program got to the point where it wouldn't let me add any more blocks) was due to a limitation on the number of sequencial blocks you can have in a program. What is that limit? I would also like to know how many variables/containers are supported by each language. I appears to me that Robolab has better controll over when you are watching a sensor than RIS has. Yes you can work around this by putting a test of a variable at the top of the watcher stack but this must slow things down. Also when a watcher stack completes in RIS the main program is started from the beginning.
Any other gotchas or limitations for RIS, Rololab, or Mindscript that anyone can share?

Here is my 2 cents worth on the language wars:
RIS below version 2.0 is bad news.
RIS 2.0 is a much better product that Robolab, for the following simple reason:
With RIS 2.0, one can hide the program's complexity through the use of subroutines and variables.
This is the most important aspect of any programming language imho, and Robolab does not have tools to do this from what I can see.
RIS 2.0 can have named subroutines, for example TurnRight or FwdDistance. I believe Robolab subroutines are numbers only, so they are very cryptic.
Robolab code appears very cryptic to me, whereas RIS 2.0 can be created to read in English like a story.
The problems you encountered in RIS are easily solvable. Unfortunately the techniques are not publicized much.
I have written a tutorial which addresses the problems you encountered with RIS and many more.
There is no limit on code blocks once you use a simple workaround. Basically, when you reach the limit of blocks (there is no way to know where that limit is, but it doesnt matter) simply set a variable (STACK, for example) to the value 2.
Set up a variable watcher to take over when STACK = 2.
Thats it! No more limits!
Also, NEVER use the sensor watcher blocks!! They don't work well. There is no way to turn them off, as far as I know. Use WAIT's instead!!

I would agree with much of what you said.
Robolab does have a very nice way to handle what I believe
are called "Big Blocks" in RIS. They are called sub-vi and
allow you to encapsulate code (as a macro not a subroutine) and even create a custom icon for it.
I do not think any program is that much better than the other. The only REAL issue is that RIS does NOT run on
Windows NT.

Careful, RIS does not have subroutines. The myblocks are inline coded and are not soubroutines.

MyBlocks also lack even the functionality of BigBlocks: the ability to take arguments. This to me is unforgivable, since they demonstrate that it can be done by them, but they don't let you do it.
It means you can't have a "go forward" block that takes a number. Yes, you can do the same thing with global variables, but it would be nice if they simply let you do what they did in BigBlocks.

Unforgivable? That is a pretty strong word, especially when you acknowledge that myblocks do what you want already!
If you want to go forward 5, simply set the variable "Distance" to 5 and execute the "go forward" myblock. It works just like you want. Simple, effective, reusable code.

Yes, it all works fine until you have two routines both using "distance".

Joel (I assume?) -
I'm curious about your admonition to never use sensor watcher blocks. They were obviously put into RIS for a reason, so to ignore them completely seems like a waste.
I think the real issue is what kind of programming paradigm you are using: procedural (waits and loops) vs. event-driven (sensor watchers). Anyone who has done any kind of modern computer GUI programming can attest to the benefits of event-driven programming: more modular, not time dependent, multi-task capable, etc. With a little practice, it becomes a much more logical way to think about robot behavior: "do this task continuously, and only when one of these sensor events happen, then do this other task, until another sensor event happens,..." and so on.
In comparision, the procedural model goes something like: "do this task continuously, and only when this one particular sensor event happens, then do this other task, until another particular sensor event happens,..." and so on. Yes, you can check for a variety of sensor events at each decision point, but it usually involves a nasty nest of "if" statements and repeated code.
In event-driven programming, usually what happens is that the "mainline" of your code is all initializations and cleanup, and the "meat" of your code is all under various watchers. A procedural program usually consists of a single massive "mainline", which granted, can be shortened using MyBlocks. However, as has been pointed out elsewhere, MyBlocks are really just shorthand for inline code which uses more memory space (and takes longer to download).
I've experimented some with RIS and sensor watchers, and to me, they seem to work fine. To get them to activate/deactivate, I just use a "boolean" global variable that is set on program initalization and then checked each time the watcher code begins to execute. You can flip the sense of the variable anytime you want to turn a watcher on or off. I'm wondering if others have really had problems using sensor watchers, or perhaps are just using them incorrectly. Or is there something else I'm missing? Any comments, please?

How did you know my name?
Is your post in response to the RIS lesson booklet I wrote?
In the booklet, I think that I mentioned the reason I recommended against using sensor watchers: my own ignorance!
I simply haven't figured out how to use them.
RIS has several commands that have no place in the FLL challenge. A quick example that comes to mind are the "Big Blocks". So yes there are parts of RIS that are what you refer to as a "waste". But RIS was not written exclusively for FLL, so it makes sense that not all the RIS commands are especially useful in FLL.
Every programming language and tool contains features that are rarely used - I don't think that is indicative of anything.
FLL programming _IS_ procedural - ie
1) go to the bridge
2) go to the building site
3) go to the windmill
4) etc.
If this were real-world robotics programming, yes I agree more event-driven methods would be employed. Because a pattern is not being followed. But in FLL, a pattern is being followed!
However, it appears to me that RIS is not so good at event-driven programming.
For example, if my kids set up a light sensor watcher to follow a line, how do they stop watching the sensor after they are done following the line?
Yes they can use the "switch" method that you mentioned once they no longer want to follow the line. But the light sensor watcher code is still being executed! The processor leaves the main line, executes the watcher code, and then returns - hopefully to where it should return.
Now after following a line for awhile, and then doing something else like delivering an object, how can they stop at a black line? In-line sensor waits won't work, they would have to play with "states" in the light sensor watcher code.
It certainly can be done, but it seems that they are fighting against the sensor watcher most of the time.
I see in RIS help that one can set and use sensor watcher priorities. Maybe these would help control the watchers - I just don't understand them!
If you can explain how to follow a line, leave the sensor watcher code to do other stuff, and then stop at a black line, I am all ears!! But it has to be simple enough for young kids!

Oops - I have to take back some of my words about Robolab. I think external subroutines can be named.
But I still think RIS 2.0 is much more powerful and much simpler at the same time!
- Message by: Eco-Nuts 10/18/2002 22:59:12 GMT
For this competition both Robolab and RIS 2.0 have the same capabilities so one is not more powerful than the other. It is a matter of which one you learned on and which one you can teach others with. Robolab does have two things that RIS does not. One are real subroutines and the other is the data gathering capability. Data gathering is not required and therefore does not matter. If you are going to teach programming as a class and use the robot to gather data then you might want to use Robolab. As for subroutines, the difference between Robolab and RIS is that Robolab uses actual subroutines that are called by the processor (this saves space). RIS uses MyBlocks which seem like subroutines but are in line coded so the processor executes a copy of the code each time (saves time, uses more space). For this competition the difference is very minor and for the most part ignored.

It's hard to answer this question without knowing how the wheels are setup on your robot.
Is it a four wheel or three wheels robot ?
Are you using two drive wheels with a motor on each ?
Are the wheels geared, if so how is you gear ratio setup ?
We use a tricycle setup with two drive wheels and a button for the third wheel. If you use four wheels, there is too much friction to make the robot turn. We also use a rotation sensor to turn the robot just the same amount each time. For this to work, you have to put the rotation sensor on one wheel and drive only that wheel to turn. To prevent the opposite from moving we apply a power of 1 to it to keep it in place while driving the other wheel with a power of 5.
- Message by: Boulan89 10/10/2002 01:42:47 GMT
You say that you apply power 1 to the wheel on the inside of the turn and a power of 5 to the other outside turn radius wheel. You must turn rather than pivot. Do you find this is easiler to control than to lock one wheel and drive the other or to drive each wheel opposite of each other to rotate around the centerpoint of the robot?
- Message by: VCMS7 10/10/2002 16:16:25 GMT
Applying a power of 1 to one wheel basically locks it in place and five to the other wheel causes the turn to occur. We found that if you are using the rotation sensor and you turn both wheels in opposite directions, that the counts on the rotation sensor are inconsistent. I believe this is probably due to the fact the the slippage on the wheels varies each time you try to turn.
- Message by: Vikings 10/10/2002 02:09:05 GMT

- Message by: Eco-Nuts 12/10/2002 20:36:06 GMT
Use a rotation sensor. Timing will always give inconsistant results as the batteries will make the motor run at different speeds based on how much the batteries have been used. The rotation sensor is less sensative and will give repeatable answers for number of rotations. The trick is to gear up the sensor to provide the resolution you need and to keep the wheels from spinning. Any wheel slippage will impact your sensor reading. The sensor will read the amount the wheel has turned and not the actual distance traveled on the mat.

To do this go to the RCX Communication Sub Menu. Select the "Change Program on RCX" icon and string it into your program.

Discussion: Robolab Tricks By: TeknoDevils 01/06/2003 22:01:22 GMT
Here are some of the tricks that may not be intuitive!
1) Use spacebar to select between the pointer and thread tool.
2) Use the tab key to select between pointer, hand, thread, and text tools.
3) Press control-b to remove all the broken wires.
4) When editing the icons for sub-vi you can use Paint! Open
Paint and under Image-Attributes select 32*32 pixels. Now draw
your icon. When done, press control-A to select all and
control-c to copy. Now jump back to Robolab's icon editor.
Click on Edit-Select all. Now press control-v to paste. Voila!
This sounds hard, but Paint is a much nicer editor.
5) The following is very very very dangerous! You can understand
how many of Robolab's icons actualy work by looking at their
implementations! Double click on an icon, now press control-E.
The sub-vi for the implementation will pop up! DO NOT EDIT!!!!!!
Although you certainly can copy interesting sections! A very
interesting one to look at are the Wait-fors. They are
implemented as busy loops with 2/100 second delay!
I would love to hear other tricks!

Skye,
In order to have generic powered sensors in Robolab, I think it is necessary to download
the "New Generic Sensors" patch from Tufts. It is not clear to me whether the official
patches, etc., from Tufts Robolab @ CEEO are permitted under the FLL rules.
The relevant FLL rule is as follows:
6) ALLOWABLE SOFTWARE: The robot may only be programmed using unaltered LEGO MindStorms Robotics Invention System or RoboLab software of any release date.
I can't imagine that official patches / fixes from Tufts (the Robolab maintainers) are prohibited, as these are equally available for all teams. (Indeed some of the patches / workarounds are essential if you want to run Robolab on a Win 2000 or Win XP machine.) However, on the other hand, they could be viewed as an "alteration" of the RoboLab software. Whether or not the official Tufts / Robolab patches are permitted under the FLL rules may be a good question for Scott Evans.
See the web page below for more information on the patch, as well as graphics of the icons that are added to the various menus. (If you download the patch, one can use the "generic powered sensor" to acquire raw values from the Light Sensor. The Light Sensor gives raw values of approximately 600 to 800, with higher values being darker.)

A tip to save time transferring programs to your robot - Once you create subroutines and load them into a program "slot" (you know, 1 of the 5 on the RCX), they can be used by any uploaded program in the slot that calls the subroutine. So if you have a huge set of subroutines, simply load them once with a vi that creates them, and then only re-load them if they change. Now you can make vi's that call subroutines that don't need any "create subroutine" functions. With big subs, this can save lots of upload time. Each of the 5 program slots requires it's own initial set of subroutines, of course, if used.

Sure. Suppose you want to use 4 subroutines: Sub1 for Forward, Sub2 for Reverse, Sub3 for Left turn and Sub4 for Right turn. Let's create these in a vi we'll call "subs.vi". This vi has a start(green stoplight) , 4 'create subroutine' function blocks, each with it's own associated subroutine branching off, and then an end (red stoplight). Let's pick program slot 3 on the robot, and now upload the program to it. Ok, now create another vi called "new.vi" containing several "run Subroutine" functions to run any or all of the subs Sub1, Sub2, Sub3 or Sub4, and upload it to program slot 3. Note that this vi does NOT need to contain any 'create subroutine' functions. Those previously created subroutines will always be available in that program slot (#3 in this example) in the RCX until they are either deleted (with the 'delete subroutine' function), written over(redefined by a new 'create subroutine' of the same number), or the RCX batteries expire.

Hi TechnoDevils,
I too use labview at work, so I taught my team to use sub-vi's as one would create them in a labview program instead of using subroutine icon branched off the main program.
I've seen some great information in this forum on how subroutines are loaded into the RCX memory.
What I am wondering is, are sub vi's treated the same way in RCX memory? Does anyone have an opinion on the advantages or disadvantages to using subroutines versus sub vi's?
Coach,
"City Champs"
- Message by: TeknoDevils 10/25/2002 17:23:22 GMT
No, sub-vi's are like a shorthand notation. Each time
the sub-vi icon is used, all the code behind it is
repeated in the code. No true subroutine is created.
A solution to this is to create two sub-vis. One with
the definition of your true subroutine. You call this one
"Thingy-init". The second sub-vi has the call to the
subroutine and you call it "Thingy".
The downfall of this solution is the inability to pass
arguments like you can in a sub-vi. If arguments are needed,
you must place them into a known container before invoking
the RCX subroutine inside your "thingy" sub-vi.
The upfall (tm) is that you can dramaticaly reduce code
size and hence download times.

This is not a trick, but rather a request for information.
It is not strickly Robolab related, but rather a firmware issue. I placed it here, because those reading this section are likely to know the answer!
My chief programer has a clear need for multiple threads of execution. In the main thread, he comes to a point where he wants to start the robot moving. To prevent wheel sliping, he must start at power level one and then to 2 and up to max power. At first he put a 20 tick rotation wait between power increments. Normally this worked great. The problem came when the bot was pushing something heavy. At power level 1, the bot was stalled and would not move the twenty clicks to go to power level 2.
Back to the drawing board.
He went to a small time delay between power increments. This worked fine till a mission needed to go a distance smaller than what the robot used up to come up to speed!
Bad to the drawing board.
His current idea, is to start a thread to ramp the motor up to speed. The main thread would wait for the proper
number of ticks. It would then stop the 'ramp-up' thread and then shut down the motors. Now he has the best of both worlds. If he is going a long distance the "ramp up" thread stops comes to end end with the motors at full power. If he is going a short distance, the "ramp up" thread meets an early death.
So after that long introduction...
If you stop a thread of execution, can it be started up again? If it can, does it start where it left off, or back at the begining of the thread?
If a thread of execution terminated on its own (red light) can it be started back up again? If so, where does it start from?
Experimentation will give us a probable answer. What we are hoping for is a definitive answer! The drawing board is getting old!
-Skye Sweeney
- Message by: ilsgreen 11/21/2002 01:02:58 GMT
Skye, I don't know for sure where a thread may start without either looking at the programming or doing the same experiments you describe. I assume the threads you discuss are task splits within Robolab. I'm also not sure if the program is trying to control motor speed by setting a container to a value based on the rotation sensor or if its a direct read from the rotation sensor count.
What I find as interesting in your post is that a low motor speed is required to start the robot in motion before higher motor speeds can be applied. In addition, pushing something heavy also affects the motor speed ramp-up. Mechanically, I'd have to guess that your team has a robot built more for speed than for torque and power. Because of the low torque, the chief programmer then has the opportunity to effectively program an equivalent of an electronic automatic transmission to get any initial robot motion. If that's the case, maybe a better bet is to always have robot motion in the main thread and always start any motion from a stop at low power using the routine described.
Given we are approaching the end of the season, the software solution is more likely to be useful than trying to change a gear ratio to get more torque, which would 1) probably create a major rebuild of the robot and 2) force every rotation sensor control command you have so far to be reset for the new gear ratio!
Good luck!

The underlining issue is one of accuracy in odometry. After
much research, we found our ideal speed was a 24 to 40
gear reduction with the medium balloon wheels. But the medium ballon wheels are very wide giving good traction on the straight but too much variability on turns. So, we found some other LEGO wheels that are the same diameter as the medium ballons, but have a much smaller tread area.
We have great odometry except that when we start we peel out! So we simply need to do a slow start. So the experiments will start even at this late date.

Mark,
The slow start method we use now is:
motor A+C on at power 1
wait 20 ticks
motor A+C on at power 2
wait 20 ticks
...
motor A+C on at power level 5
wait till (parameter) ticks have gone by.
The new version replaces the wait for 20 ticks with a small time delay. This solve the start up problem pushing something heavy. It does not solve the start going only a short distance problem. But I think we will simply have a new sub-vi for moving short distances that only ramps up to power level 2.

Using Robolab 2.5, our robot's speed range is too limited. Speed 5 is about 8 counts per second while speed 1 is about 7 counts per second. Is there some way to write custom speed settings so the motors will go slower?
Tim
- Message by: Eco-Nuts 11/27/2002 17:49:02 GMT
The documents are sketchy, but looking at the firmware command structure, power is defined as 3 bits ranging from 0 to 7. So 1 - 8 are the levels you can program. The reason you are not getting much difference in your speed is that what you are controlling is not the speed of the motor but the power to the motor. The speed of a motor is mostly controlled by the voltage to the motor. The RCX changes power levels by producing a pulse width modulated output. That means that the same voltage is put out for a variable duration at a fixed frequency. This amounts to varying the duty cycle and therby the power to the motor. The power to the motor is not critical until the weight of the robot is great or extra force is needed to push something. A light robot on wheels does not need much power to reach it's limit of speed (due to voltage). As you can see from your experiment that you most likely reached max speed at a power level of 2 or 3. The max speed of your robot is much more dependent on the voltage in the batteries. As the batteries wear down, the speed of your robot will slow down and lower power levels will not be enough to overcome the weight of your robot and higher power levels are needed to reach max available speed again.
So in summary, you are stuck with the speed vs power settings. The speed vs power is mostly defined by the robot weight and friction. Increase weight or friction to have more control over the speed.

We tried constants of 0 -7 and surprizingly a speed of '0' is not stopped, but actually about the right speed for our robot. Frankly, it seems easier to set speed settings the way you suggested instead of the 'canned modifiers', plus we can fine tune the speed/power settings more closely.

Skye, does it actually cause grief with the method described, or is that a feeling? It seems like the subVI would execute to jump only within the subVI for that block.
Perhaps your team could go to numbering jumps (white jumps with numeric modifiers) and reserve each number so it is only used in a given subVI and not any other subVIs.

Skye,
The best I can suggest would be the traditional "abort flag" mechanism. This hardly
meets your criteria of "simple", however, as this is not a basic programming concept.
Something like the following would work, however:
Set "container of choice" = 0
Loop while "container of choice" = 0
(Body of loop goes here)
Fork on odometer >= desired value
Set "container of choice" = 1
Fork on light < 40 (sufficiently dark)
Set "container of choice" = 1
End loop
Not particularly simple, but essentially, the loop is on an "abort flag." The flag starts out
cleared. When either condition you are waiting for occurs, the flag gets set, and the
loop exits.

- The text box inside color and the text frame can be set to colors other than white and black using the colors palette. The lower right color box controls the text box color. The upper left (and more forward) color box controls the frame color.
- Changing the text box color to 'T' for transparent and then increasing the text box size can allow a certain section of code needing a comment to have a box around the code and the comment. Look for the 'T' in the lower left hand corner after left-clicking the color box.

Re: Robolab 2.5 having anything similar to a "repeat until" block...
Robolab does have a whole bunch of "loop while" structures:
loop for a certain number of times
loop while a container is < or > some value
loop while a sensor is < or > some value
These provide very similar functionality to the "repeat until" structures in RIS.
For example, if one has a line-following algorithm, one can put the algorithm
inside the repeat block. As an example of this in "pseudocode," the following
pseudocode would follow a line until a value of 100 is reached on the rotation
(angle) sensor.
The above program will start following a line for a distance
of 100 on the angle sensor, and then stop.

To add one comment, the difference between while and until is only in the first iteration. A while statement will block the following code from executing if the condition is not met. The until condition will allow the code to execute once and then decide to continue or not. If this is important to you then you have to plan your code for these two conditions.

If you are using Robolab 2.5:
If you want a line follower to run only for a certain number of seconds use a Timer Fork. This is found in Structures. If your line follower is on a Light Fork - add a Timer Fork right after the command for the light sensor. Be sure to reset the timer to Zero (with the Zero Timer before you start your line following) Then have the Timer Fork read the number of seconds you want to stop at. If it reads less that these number of seconds have it Jump back and Land to the beginning of the light sensor fork. If it reads equal or greater than these seconds have it jump out of the loop (fork) and go to the place where you want to continue the program.
If you used a light sensor fork for your line follower then it splits depending on the reading of the sensor. You will have to add the timer fork to both the top split and the bottom split. These two forks will have to merge and then the whole thing will have to merge again to complete the merge of the original light sensor fork.
Attached is a word document with a picture of how this can be done. The program follows a line for 5 seconds and then goes forward for 4 additional seconds.

Run the loop. Later... Is -199 greater than -200, Yes!

-199 is indeed greater than -200. It is closer to +infinity

The front touch sensor hits the current field's east wall prematurely behind the building material shelves some of the time and it causes it to continue to next program instead of line following to the north wall.

Assuming you are using Robolab...
Set up your outer loop not as a rotation or touch sensor loop, but rather as a container loop.
1) Set the red container to 0
2) Start the loop using "Loop as long as the red container is less than 1"
3) Put the line following algorhym as the guts of the loop.
4) Create a rotation sensor conditional "If rotation count is greater than N"
4a) On the false path, do nothing.
4b) On the true path, place a touch sensor conditional
4bi) On the true path, set the red container to 1
4bii) On the false path, do nothing.
5) Close your loop.
So the red container only gets set to one to terminate the loop if the rotation sensor
is greater than some value and the touch sensor was pressed.
How you would do this in RIS I do not know, but it might give you an idea.

Discussion: Programing hint for competition By: cranium 10/31/2002 22:04:50 GMT
Here's a handy hint about programing for the competition.
At the top of all of your programs place something similar to this pseudo-code;
beep,
display (your team #),
wait 0.5 seconds
This code does several handy things;
1. Waits for a short time to give the roboteer time to get their finger off the robot.
2. "Debounces" the robot from the roboteers button push.
3. Gives audio feedback that the button push was accepted (so the roboteer doesn't hit the button again).
4. Displays you team number (or other unique tag) that lets you know that the correct program is loaded.
At a competition you have to be careful of accidentally getting your robot reprogramed by another team. This suggestion always displays your team number (or whatever you like) at the start of a program. Very handy for that last minute check before going to the competition table to make sure the proper programs are loaded.
The time delay suggestion was posted last year. The beep and display suggestions are new (I think).

A guru question...
This year the team wants to emmulate their arch rival (LRT)and perform all missions using odometry. We have a good start. The robot drives straight and the rotation sensor is geared up a bit to run faster than the motor. The robot has 24-40 gear reduction to the medium balloon wheels. The robot is quick, but not overly so. What we are having troubles with are turns.
When turning by stopping one wheel only, we are fairly repeatable. The odometer count is up around 120. When doing a pivot turn (motors in opposite directions) the
repeatability goes way down. Our counts are now about 45 and looking at the display, the sensor actually is getting to about 52. The motor is unable to stop so fast and the
sensing loop in Robolab has a finite speed.
A one wheel stopped turn is not possible in all locations
due to the size of the bot. Any ideas on how to increase
our pivot turn repeatability?
I suppose we could do a "3 point turn" put that would be
pretty 'ugly'!

My example goes off maybe 1/2 inch in 8 feet. What are you using for the "third" wheel? I think using a large wheel with no tire is probably the key here. A caster or button is probably the worst thing.
If you look at the drive, most of the gear backlash is from the turning side of the system, and does not affect the drive side. This is not a problem if the rotation sensor is attached to the output axles, since all the backlash is taken up before the wheels start turning.
--Jack Gregory
- Message by: TeknoDevils 10/18/2002 15:47:07 GMT
Jack,
Our +- drive used the medium balloon wheels and a button for the third wheel.
Each little bump along the way caused the bot to rotate right or left using up
part of the HUGE slop in all the gears.
If we had added a more directionaly stable large balloon minus tire, it might have
been better. That will have to wait for next year, as the bot is near completion!
Too many experiments, too little time!
I think I may put my best software kid on a software solution to the turning problem. If the
bot where to turn slower using a lower power level, we would gain repeatability. But the
power level itself will have to vary based on load (sometimes we are pushing something).
What I would give for a second rotation sensor! Yes I do know we can build one from other
sensors, but the team has not caught on yet.
-Skye Sweeney
- Message by: SharonA 10/18/2002 19:56:32 GMT
You definitely want to make it harder to turn than to go straight. A button is the worst case, as there is no bias. Casters suffer from initial bias. A wheel without a tire is ideal, because the plastic slides easily enough when forced, but it would much rather just turn the wheel (assuming it is free to rotate).
As an aside, the friction level on the un-tired wheel is a function of how much weight it is carrying, so it is possible to have very fine control over the forces involved. Most of the weight should be on the driving wheels.
You can't be done already! Our kids make massive changes in December!

Newbie here (Almost 1 local tournament under our belt.)
OK Yesterday I had our 2 builder totally start from scratch to fix 3 problems - increase speed, make it stronger, and add a rotation sensor.
So I read this thread and checked out the baker website and saw your reference to a dual differential drive. I am not sure what this would look like. I would also like some help in figuring the ratio or rotation speed at my rotation sensor since if it is too slow or too fast it will be inaccurate.
So coming off the motor we have 24 to a 40 to the balloon wheels and then also coming off the motor we have 24 to 40
on the same axle an 8 to 8 to 8 on the axle coming into the differential gear. Same comes off the motor to the other side of the differential. Then off the smaller set of teeth on the outside of the differential (16 I think) I have a 24 which then goes to the rotation sensor.
Gear ratio I think goes something like
3/5 X 5/1 X 1/1 X 1/1 X 1/2 X 2/3 which doesn't this all cancel out to 1. Is this correct?
And so on to the dual differential drive (adder/subtracter)
What does it look like? With our current setup the rotation sensor will measure forward if both motors are running or if only 1 motor is running but it basically does not rotate if you do a spin (one motor forward the other back.)
We have not tried to program any task yet as the team has not completed rebuilding the base yet. I did read on this thread about turning with one motor while braking the the other producing countable rotations (playing with what they have so far does produce this) Our past tasks had used spinning (with the best accuraccy timing can give) with only 4 weeks to our state tourament the team needs to get our robot base finished at our next meeting. If this addersubtracter thingy will lead to more accuracy odmemetry the now is the time for our team to implement it.
Also I was encouraged to hear that other teams are also doing major modification this late - SharonA I think.

Anyone can make a robot go forwards and turn. It is the understanding and clever solutions to detail problems of navigation and manipulation that sets the teams apart. I find it a wonderful experience to go to a tournament and see all the very different solutions to common problems. I don't want to know how other teams are solving them, and I don't want to tell others how we are solving them.

Every time we try to program the rotation sensor it jumps to program 5 - is that a default?

Something sounds quite wrong!
What language are you using?
I would first pull a battery and wait 1 minute. Replace
it and you will be forced to reinstall the firmware.
If it still does not work, post the offending code. My
guess is that you have a corrupt firmware.

I've noticed that the Lego RIS software defaults to slot 5 automatically. If you want to change that go to the 'Settings' pull-down and select the new slot. The next time you download it will use the slot you selected.
Also by default, program slot 1 is locked. To unlock it (and also enable the rotation sensor) you need to use the 'Settings' button on the main menu. You can lock/unlock the slots in the Advanced dialog.

Some things to note about the rotation sensors...
1. They will count up or down by 16 for every revolution of the shaft. If you use gears, you can increase or decrease that number.
2. Remember that they count up and down depending on direction. If they count down, you will want to test for less than a negative number.
3. Always use the less-than and greater-than functions when testing rotation. If your robot is really fast, you may not be able to catch an equal-to condition and the robot will run forever.
4. Test your rotation sensor using the view function on the RCX. We got a bad sensor in our kit and it drove us nuts for a while....

Test your rotation sensor using the view function on the RCX.
We find it useful to display the rotation sensor value while planning and debugging missions. We are using Mindscript, and an easy way to do that is to use the DISPLAY command at the start of the program to force the rotation sensor value to be displayed. This is a lot easier than fumbling with the VIEW button on the RCX.
- Message by: ilsgreen 11/05/2002 19:52:59 GMT
The same "View" command also exists in Robolab 2.5. I don't remember for sure where it is found, but I believe it was in a sublevel of the RCX commands. The command says "View" on it.

How do we use variables to measure distance with our rotation sensor?
- Message by: Eco-Nuts 11/06/2002 16:15:48 GMT
I am not sure what you are trying to do. Are you using a loop around the rotation sensor?
In RIS is is repeat while or repeat until. In the block set the sensor to rotation and use greater than for forward rotation and less than for reverse rotation. For the value use a variable in place of the number (use the pull down menu and select variable). Now above the loop you can set the variable to the value you want. If you place the loop in a myblock and proceed the loop in the myblock with a rotation reset you will then be able to set the variable outside the myblock to determine how far you want to go in rotation counts for each movement.
In Robolab it is very similar, you can select a container in place of a number for the rotation branch. My blocks are replaced with either subroutines or sub vi. The same principles apply.

Ok, my programmers have yet another question that their non-programming coach isn't sure how to answer!
They have discovered that the rotation sensor does not always accurately count during turns (they have a treaded robot - because they like treads - and the contraption that they are using to deliver items is heavy so....the bot turns are very, very slow). Is this a programming or a mechanical problem? My guess is mechanical. So their question is: which is more accurate over the long haul - a rotation count for the turns or a timed turn? And which is more affected by battery level? They have been messing with this for quite some time and their frustration level is becoming too high. Thanks for the input!

We have had some of the same problems. Being a rookie team, this has been our main struggle. My feeling is that your battery levels affect the robot with heavy attachments when you are turning regardless of whether you are using rotation counter or timing. The friction between the wheels and surface are different depending on the power level supplied by the batteries. I think it is both a programming and mechanical problem. Mechanical in the fact that friction between surfaces affects the rotation counter, but programming because speed, power, and direction affect your turns and you have to learn the right combination of these for your robot to make accurate turns.
Solutions could involve:
1. Shifting the weight of the attachment more towards the center and/or back of the robot so that it does more pulling than pushing.(we had to do this on one arm!)
2. Make sure gears are not binding and affecting rotation counter.
3. Our best results came from learning to use other objects to control our turns. They discovered that if you want to stop straight and parallel to the market wall, then put a wheel on the right hand side of the bot and then make your turns based on time and turn past where you need to be and let the wall stop you. We wind up almost perfect every time. Works better than trying to time it exactly and winding up a little short or a little long!! We also use this in another spot very accurately.
Kind of late in the game for these kind of changes but best of luck to you in your competition!!

Marie,
The short answer is that the reason the rotation sensor gives inconsistent counts
during turns is that a treaded robot or a four-wheel drive skid-steer robot (like the
"Bobcat" mini-loader) only turns through slippage of the treads or wheels. If the
friction varies at all from time 1 to time 2, then there will be a variance in the turn
for either a timed turn or turns using the rotation sensor. Also, any variance in the
battery level, weight of the robot, dust on the table, etc., will introduce similar
inconsistencies. There really is not a direct solution to this problem on a tracked
robot or 4-wheel drive skid-steer robot.
That said, there are ways to work around the problem -- try to minimize the variance
of things which the team can control. Have them try to think of ways to always have
the same level of batteries, weight of robot, dust on the table, etc., and they will
get much more repeatable results.
Other alternatives are for them to do no more inconsistent motions than they absolutely
must. If the robot does not turn consistently, but goes straight well, have the kids think
about how to minimize the number of turns they need to make. Alternatively, use the
sensors to have the robot keep track of where it is.
I wish your team the best in getting past this one. The frustration level can get very
high from this issue, but this is a problem shared by all teams. The fact that your
team has even realized the extent of the problem is an accomplishment for them to
be proud of! From what I have heard, many teams never even discover these inherent
inconsistencies.

Treads are tough - I have never seen a treaded robot do that well, but I'm sure there are solutions.
The secret of an FLL robot IMHO is to have two points of friction - a left front rubber wheel and a right front rubber wheel for example. The rubber contact point is only a few millimeters long in the direction of travel. This allows the robot to turn with little friction (except for that few mm).
The problem with treads is that there is 4 inches of friction - I'm not sure how to overcome this.
And have two points of non-friction - one or two back wheels WITHOUT the rubber. This is the only way the robot can make somewhat accurate turns.
Although even the best robot will be far off. When turning 90 degrees using a geared up rotation sensor, my kids robot turns between about 70 and 110 degrees.
With that much inaccuracy, a 90 degree turn followed by a three foot forward motion is pretty much always lost.
My kids always have to use landmarks to find out where they are.
examples:
Drive forward until a wall is hit;
Turn right until it cant turn any further;
rotate left until a black line is reached;
etc.

Rotation sensors have a know limitation when rotating
slowly. They may not provide an accurate count. The
rotation of the sensor starts to fail bellow about 50
RPM. A solution is to gear up the rotation sensor so
that it turns at a faster rate than the motor.

We're been very frustrated with the rotation sensors not doing the same thing everytime. That's been the most time consuming of any of the kid's programming efforts. Things will work great some of the time, then go way off course or not turn correctly another time.
Our robot has wheels this year. Last year we had treads and came in third in Arkansas (had light sensor problems on one of the challenge tables otherwise probably would have done even better). But we didn't use rotation sensors at all. This is the first year we've tried them.
This is a lot of great info to think about.
We're just got one day to go before our competition, just one more day of practice so can't do much more, however what's been posted here this will certainly give us more food for thought for the future.

Just to add to your list of things to look at...
1) RS going too fast will report bad distances
2) RS going too slow will report bad distances
3) Wheels spinning out on start or stop
4) Turns are always a problem in that you are trying to
turn very few ticks and each tick represents a
significant turn angle. The wheels are also 'scrubbing"
and this is not always repeatable.

Thanks, this will be something we can look more at AFTER tomorrow.
Try as we may, we just were not able to finish one of the missions each time due to rotation sensor problems. But if the rest of the missions go ok, we can still get a respectable score. If we had a few more weeks we could probably solve the problem, but in the end this is a good lesson for the kids to learn sometimes the clock moves on even if you are not ready.

Discussion: Turn Right ok in Try it but goes much further in program By: Operation Stanley 10/28/2002 16:43:34 GMT
We are having trouble turning our robot. It works fine in a other programs but in our current one it has unexpected results.
If we use the try it with a value of 2.75 seconds when turning right it does a 90 degree turn.
Within the program this same value goes 180 degrees.
Any ideas?
We tried moving the turn to the top of the program and still got these weird results.
thanks in advance for your comments
- Message by: Patriots 10/23/2002 18:19:11 GMT
I'm not sure what kind of program you are using - or what you mean by the same value going to 180 degrees or moving to the top of your program but I can tell you this:
If you count on turning by using time you will have problems when your batteries start to run down and it doesn't turn as far because the batteries are weak or it turns too far when you put new batteries in. The best way to get an accurate turn - each and every time is to use a rotation sensor. If you're using Robolab you can download a simple Jump and Land program with a rotation sensor in the middle and then you can use the view button to see how much you need make the rotation sensor move to get any different kind of turning angle. (Sorry - but I'm not familiar with the RIS software.)
- Message by: Eco-Nuts 10/24/2002 00:04:43 GMT
The try it is not going to behave the same as the program. The try it only tries one command and then ends. When you run the program it will continue to run until it hits a end program or you manually stop the program. One thing to look for in the program is to make sure you turn the motor off after each set of commands, otherwise the motors will continue to turn. If your program has sensor watches it will execute slower than a program that does not. Again when you use the try it you are only running that command and no other commands (it does not have to interupt and check the watch sensors). Patriots are correct you will never get a repeatable turn using time. For this competition you should use a rotation sensor for repeatable motion of any kind. Time will always be variable as some days the motor might be faster than other days plus the power of the batteries is never the same. Timed events should only be used where precision is not required.
