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.
