SUMO CHALLENGE

DESCRIPTION:

Sumo-bot competitions pit two robots made entirely of Lego Mindstorm (NXT, EV3, Spike, or 51515) components against one another as they attempt to push the other out of an arena using sensors, clever programming, and innovative design. The last robot standing inside the ring (Dohyo) wins, while the first robot to hit the ground outside the ring loses. The robots can be no larger than 20 cm on each side and no heavier than 2 kg.

In each round, the robots will start from the following positions:

WHAT KIND OF ROBOT SHOULD I PARTICIPATE IN THE COMPETITION?

  1. Robots are limited to using a single functional controller (NXT, EV3, Spike o 15151).
  2. The utilisation of motors and sensors is limitless.
  3. The robot must be autonomous. It should not be remote controlled.
  4. The robots must have displayed a number, offer by the organizers, on the outer casing of the robot in a visible place.
  5. Bluetooth and Wi-Fi connectivity must always be turned off, and USB must be used for software uploads.
  6. The maximum weight for all participating sumo-bots is 2 kilogrammes.
  7. Maximum Dimensions will be 20cm in Width and 20cm in Length. There is no height limit.
  8. The robot must count down for 5 seconds after being activated before it may begin to move.
  9. The robot may unfold components as it begins to move.

DOHYO ( SUMO RING)

The ring (Dohyo) for the contest is a circle 77 cm in diameter, with a 2.5 cm white border. 

JUDGING:

Each match will be judged separately by a single person. A chief judge who makes final judgments will settle disputes. According to the chief judge, the content may need to be replayed after conferring with the match judge. Here, the full three-minute game will be repeated.

A bout between two sumo-bots will last three minutes unless the judges decide to extend it.

PLEASE REMEMBER:

  1. Lego Robot Sumo competitions take place on a level circular ring 77 cm in diameter and have a white border around the outside 2.5cm thick. The ring (Dohyo) is about 1.5 inches above the ground and is made of smooth plywood painted flat black.
  2. Sumo-bots, the competing robots, must all be built only from LEGO structural components that have not been altered. They must also be fully autonomous, designed to function without human intervention. During each battle, the robot must be able to move and use its mobility (cinder blocks are not permitted).
  3. The competitor must bring all necessary equipment (parts, tools, laptop, etc.) to the competition site. The competitor may make hardware and programming adjustments when the jury allows time.
  4. During competition times, communication between the participant and the coach is forbidden.
Judges’ decisions are final, and they reserve the right to disqualify any robot not adhering to the rules or exhibiting unsafe
behaviour.
