What is ROBO-ONE?

ROBO-ONE is a martial arts competition for biped robots held twice a year since 2002. The contestants defeat their opponents by punching and throwing techniques. In the regular competition, a three-minute, one-round, three-down tournament is held to determine the strongest biped robot.

A performance division has been newly established since the last competition. In the Performance Division, the robots are to perform in a cool, beautiful, and fun way that will excite the audience and make them want to watch again. At least three judges will score the performances, and the top robots will be eligible to compete in the Fight Division.

Number of entries: 96 robots

Performance Division: 96 robots Fight Division: 48 robots

What is the Performance Division?

This is a division in which participants are free to show off the performance of their biped robots. The robots have individuality based on the ideas of the participants. There are various types of robots, such as robots with long or short arms and legs, robots with large hands and feet, robots with cool exteriors, robots with built-in systems that operate automatically, and robots with distinctive movements. In the fighting competition, participants basically compete in striking and throwing techniques, but in the performance division, there are no detailed rules, so participants can appeal to the public in any way they like. It is also an opportunity to test the presentation skills of the participants.

What is the ■Fight Division?

This is a tournament-style fighting division in which robots that have achieved excellent results in the Performance Division, as well as the winners and top-ranked robots from each regional competition, participate. The winner is the first robot to get 3 downs in a 3-minute round. It is not easy to take down a robot that walks around the ring at high speed. The tactics between the fighters is one of the highlights of the event.

Attraction of ROBO-ONE

Participants design, process materials, assemble, and program one robot by themselves. It may take several months to more than a year to complete the project, which makes the preparation a lot of work. For this reason, they are able to acquire a wide variety of skills and knowledge, including those related to mechanisms and electricity. In addition, a robot completed with hard work does not always turn out to be a strong robot. In ROBO-ONE, competitors face each other in the competition, but between matches and at social gatherings, there is a lot of exchange of information among competitors. In ROBO-ONE, although they face each other during a match, they actively exchange information with each other in between matches and at social gatherings. In addition, through student classes and club activities, some skills are passed on from one friend to another and from senior to junior. ROBO-ONE is not only a martial arts event that can be seen from the outside, but also a place where each participant has his or her own drama from the beginning of the robot design stage and grows as a person.
