YouTube - Cockroach Controlled Mobile Robot: Video at YouTube:

"By Garnet Hertz (2005) 'Cockroach Controlled Mobile Robot' is an experimental mechanism that uses a living Madagascan hissing cockroach atop a modified trackball to control a three-wheeled robot. If the cockroach moves left, the robot moves left. Infrared sensors also provide navigation feedback to the cockroach, striving to create a pseudo-intelligent system with the cockroach as the CPU."
