Unofficial FLL FAQ06-c - Sensors

Q9.1) What is the touch sensor good for?
A) Lots of things. The simplest is a bumper sensor. Other more novel uses for the touch sensor are best left to be discovered by your team. Have them research on the web or look at the numerous Mindstorms books available. The Minnesota FLL High Tech Kids web page (http://www.hightechkids.org/fll) is another good resource.

Q9.2) We have heard that resetting the rotation sensor is valuable. Please explain!
A) The rotation sensor can be reset to zero just like the trip odometer in your car. Being able to reset the rotation sensor can drastically simplify software. Both RIS and RoboLab have reset commands.

Q9.3) We have connected a light/touch/rotation sensor to the RCX, but using the LCD display in 'view' mode cannot see any variation in the numbers.
A) The RCX probably does not know that you have a light/touch/rotation sensor attached to that port. Each sensor requires that the RCX 'listens' to it differently. Download a simple program that uses the proper sensor on the given port. Run the program once. The RCX should now know the proper configuration and give you the right results in View mode.
