why? Is line following bad? It will be IMPOSSIBLE to build an autonomus
NASCAR style car from Mindstorms. You just can't get enough information
about the track & your position into the RCX.

With the gray-scale scheme Gus suggested, a robot would be able to choose
the line/shade as it goes around the track. It could choose to follow
light-gray/white, and at the right second, move to dark, and then back to
light (through the apex of the corner) Generally the robots will have NO
idea how close they are to the wall, unless they hit it (and have a touch
sensor).
I have a big suggestion. How about creating a new sport. (this may never
catch on, but what the heck...)
LEGO Racing.
For it to catch on, (for many people to try it) it would have to be possible
& easy to do at home. So it would start with one class, limited to only
Mindstorm RIS parts. 2 motors, 1 light & 2 touch sensors.
The track should be easy to re-create. On a 4x8 piece of wood, it would be
easy to make a 2 ft wide oval track with 4 ft long straights. It would have
boards around the edge, and a 4 ft board in the middle. If you've ever seen
the First Lego League table, it's just like that. (without the board in the
middle)
This, alone, could make a good spectator event. Cars crashing into each
other as they bounce off the walls.
But then it would be easy to print out the mat on a standard printer (not
durable) and cover the bottom of the table. What size are most plotters?
Advanced cars could attempt different methods of following the track while
simple ones go until they hit the wall, then turn!
Does anyone have an opinion about this?
