This was my first attempt at a sumo robot, built about 8 years ago, it used 2 servos for propulsion, and had a Basic Stamp 1 to control it, it had photo cells under the front ramp for edge detection, and a IR led and receiver to find its target. It has now been pulled to piece's and the part used in other robots, except the BS1 which i think i fried. :(
