Hiroshima University will host Hebocon, a robot sumo tournament for people with little technical skill. Participants bring homemade robots that may be clumsy or poorly engineered; unexpected behavior and failures are part of the fun rather than something to hide.

The events are scheduled for December 5, 2026, and February 13, 2027, at Omoshiro Lab in the university's engineering building, from 10:30 a.m. to 5 p.m. Eight teams can enter each event, including participants from outside the university. The first application deadline is November 7, and a basic robot-building workshop is planned ahead of the second event.
