Beep-Beep

I designed this robot for a race organized by the Italian Lego User Group. In this race, called Grand P-RIS, two robots run on a gray track delimited by a white border on one side and a black one on other side. The rules forbid following one of the borders, which the robot can use only to correct its direction. The rules also say that only the sensors and motors included in the original RIS kit are allowed, though there's no limitation for other Lego parts.

Actually there's not much to say about this robot, which is a simple differential drive. There is a front caster (not visible in the picture, a light sensor shielded to limit interference from ambient light, and two bumpers to detect collisions against the opponent.
