How does the cockroach move the robot?

The cockroach is placed on top of a modified trackball – a computer-mouse-type device – that is hooked up to some electronics. The cockroach is held gently in place above the ball so that when the cockroach moves it makes the ball spin: a little bit like a two-dimensional treadmill. The electronics (optical encoders) within the trackball send out small electrical pulses to some electronics that make the motors move in a similar direction to where the cockroach is moving on the ball.
