The robot in the video above is driven by a cockroach. The cockroach is strapped on top of a pingpongball and the pingpongball is on top of a robot. By moving the pingpongball the cockroach decides which direction the robot will go. If it is about to hit something then lights start flashing. The cockroach will instinctively try to move away from the lights and this way also moves away from the objects it is about to hit. Weird!!!
