A sumo robot is a small, autonomous or remotely controlled robot designed for robotic sumo wrestling competitions. In these contests, two robots face off in a circular arena, known as a dohyo, with the goal of pushing their opponent out of the ring. Inspired by the Japanese martial art of sumo wrestling, sumo robots are typically equipped with sensors, wheels or tracks, and powerful motors to maximize speed and traction.
Sumo robots come in different weight classes, from tiny nano sumo bots to large mega sumo robots. These robots are often equipped with infrared sensors to detect the edge of the ring, ultrasonic sensors for detecting opponents, and high-torque motors for rapid and forceful movements. The robots must be carefully engineered for stability, speed, and power, with low center of gravity designs often being favored to prevent flipping.
