I've done a bit with BEAM Robotics, and a somewhat popular type is a rolling 
ball that can track a lightsource by shifting weight around inside, which 
might be a good system to look into. My connection isn't working right now so 
I can't double-check www.solarbotics.com, but I am quite sure that they sell
