Roboticist Garnet Hertz has mounted a Giant Madagascan Hissing Cockroach that drives a small mobile robot around by walking on top of a Kensington trackball. Great photos.

There is a row of proximity sensor triggered LEDs that shine light in the roach’s eyes, making him steer the robot since roaches instinctively avoid light. Garnet’s web page ‘Control and Communication in the Animal and the Machine’ details the project with several images of the roach in action. Debugging the project is inherently impossible.
