History



What is Robot Sumo?

It is a robotics competition category that simulates the Japanese national wrestling sport: Sumo (相撲). Robot sumo has two types of robots: RC and Autonomous. The first one is controlled by an operator through a radio-control system and the autonomous type is operated by itself with a computer code loaded in its system.

Robot sumo must weigh 3 kg or less and must measure 20 cm depth x 20 cm wide or less (no restrictions on Height) .

Two robots are placed in a Dohyo (fight area), when the judge says “Hakke-yoi Nokotta” the robots start fighting.

Basic Rules

A robot sumo wins when the opponent robot touches the outside area of the Dohyo and must be design only to push, designs with weapons or devices to damage the other robot are prohibited.
