What’s XSumo?
XSumo is a duel between robots, which is made up of two parts: following the line on a ramp and the actual sumo match. At first, the robots move along the ramp to the battle arena, and the fastest robot gets point for this. In the sumo arena, the robots try to stay on the match platform, and try to push the opponent out of the arena. The last robot left in the arena wins the match.
