StampBug walks by using the alternating triangle method. At any time he has the front and back legs of one side on the ground, the centre leg on the opposite side is on the ground also. The alternating triangle method is the simplest system that allows StampBug to walk forwards and backwards in a straight line, and allows left or right turning. StampBug proceeds in the forward direction until one or other of his feelers detects an obstacle, whereupon StampBug backs up and then turns either left or right depending on which feeler was touched before proceeding on its way forward again.
