An attached wind-up generator allows you to create electricity to power this Sumo wrestler robot. No batteries needed, just some cranking.
Forward and reverse walking actions are controlled by which direction the generator's handle is turned. The faster you crank, the faster it moves.
While its a neat kit on its own, the real fun comes from testing your Sumo-bot against another. A flurry of cranking robot action!
