I'd say forget the math and find the guy who did that elaborate pneumatics
test with Mindstorms. He'd probably tell you to create a car that housed the
RIS and hook the rotation sensor up to a wheel that rested on the track.
Then you could keep track of speed and distance, reverse the direction on a
whim, etc.
I wouldn't really do this because I would be afraid the thing would fall off
the track but under supervised conditions it would definitely work.
