Mini Sumo

Mini Sumo

A robotics competition category for high school and university students, where participants design fully autonomous mini sumo robots aiming to push their opponents out of the standard dohyo.

Important: The information provided on this page is a summary. All teams participating in the Mini Sumo category are required to thoroughly read both the Category Guideline and the Application Guideline.

🎯 Objective

The objective of the Mini Sumo competition is to enable students to develop fully autonomous sumo robots by integrating electronics, mechanical design, and software components. The competition aims to apply perception, decision-making, motion control, and strategic planning skills in a real competitive environment.

🧠 Theme

In matches held on a standard-sized dohyo, mini sumo robots are tested on their ability to detect opponents, react quickly, and execute strategic movement plans in order to push the opposing robot out of the arena.
