Thermidor 2 was a robot designed to resemble a lobster. It was armed with a very powerful flipper, with spring-loaded claws either side of it, and the wheels of a Mini Metro. These wheels were big enough for the robot to run inverted, but this wasn't necessary, as the flipper could self-right the robot. The real Thermidor 2 was well known for flipping 4 robots out of the arena in its run, including 2 in the same fight.
