An idea we have (but no implementation ideas yet), is to drive the program in
discrete 'steps', sampling the sensors during the step, and decide the action.
This would make exact turns possible. The main problem here would be to
distinguish between the square blocks, and the round ones (try to measure 'on'
time?), and select different actions.
With light sensors instead, perhaps you can distinguish different colors? I
don't have any light sensors (CM, remember?), so it's just a guess.
