Sumo Robots
The obsession with robots fighting goes all the way back to Rock ‘Em Sock ‘Em Robots, if not beyond, and those weren’t even real robots. Sumo Robots ($50) jab their arms just like those plastic guys, but they also have an infrared sensor beam to zero in on a target. Once the opponent is located, look out, because Sumo Robot zooms over on treaded wheels to knock him out of the ring.
