At least this cockroach won't be able to sneak up my pipes. This little ditty is being called a cockroach controlled robot. But it's not really a robot since the machine is exagerating the movements of a free agent inside the robot. Still it's a pretty neat idea - the roach is sitting on top of a ping-pong ball and the movements of the ball are sensed by a computer, sort of like a mouseball. The movements of the roach are then translated to the wheels of the robot. It appears as though the direction the roach travels in is loosely controlled by shining lights in the direction that the operator does not want the machine to travel. The idea being that the robot will travel towards the dark.
