Description: Robotic sumo is a competition where two robots, known as sumo-bots, attempt to push each other out of an arena using sensors, clever programming, and innovative design. The arena for the contest is a 4-foot diameter circle, and the time given for each round is 3 minutes. Your goal is to create a Sumo-bot that can push its opponent out of the arena before being pushed out of the arena by the competing sumo-bot.
All participating robots, known as sumo-bots, for ages 12 and above must also be completely autonomous—that is, programmed to act independently of humans.The robot must be able to move and use its mobility during each match without exiting the circle. For ages 11 and under remove controlled robots may be used but must meet the size requirements listed.
Construction, Weight and Size:
Robots may be constructed from any brand kits. Bots are limited to no more than 4 motors and 4 sensors and must weigh no more than 8 lbs. The maximum size specifications are:
- Maximum Width: 12 inches.
- Maximum Length: 12 inches.
- Maximum Height: 18 inches.
All sumo-bots must comply with these size limitations at the beginning of a bout, but can expand beyond these limitations after the bout has begun.
Please note that your sumo-bot will be checked for weight and size specifications as well as mobility before being admitted. You will be given the chance to modify your sumo-bot’s weight and/or size if it exceeds the 8 lb. weight limit and/or the size limits. Sumo-bots that fail to meet these specifications by the end of the Check-In period will not be allowed entry.
Failure to adhere to the following guidelines will result in disqualification:
- Mechanical: Robots must be purely mechanical.No use of fluids, chemicals, etc. (aside from the batteries used to power the robot).
- Dangerous: The robots must not contain parts that might be dangerous if the robot is picked up.For example, there should be no edges that are sharp enough to cut someone from casually picking up the robot.
- Operation: The robot must not operate in a way that will have a significant chance of damaging another robot or a bystander. The winner of each round will be the robot who can push the opposing robot from the circle.
- Interference: The robot must not interfere with the operation of the opposing robot.
- Other constraints: No robot shall be at odds with the intent of good sportsmanship.
Determinations: All questions concerning rules in this category will be determined by the Head Judge in consultation with the tournament organizers.The Head Judge's decisions are final.If you are concerned with some element of your robot, you may request a preliminary ruling prior to the event.While a preliminary ruling will likely stand, further consideration may be needed if new information is presented.
The Programming: Contestants may use any firmware or software language for their CPU. Multiple programs on the CPU are allowed. If, during the event, any contestant deems it necessary to change or update his or her program(s), he or she may do so, as long as the contestant’s sumo-bot is not currently participating and is not currently needed on the arena.
Spectator Exclusion Area Specifications: A 12 foot square area will establish a spectator exclusion area. Only three persons are allowed inside this area during a match; the judge and one robot operator for each sumo robot. Three sides of the square will be roped off to allow spectators to view matches. The fourth side of the area will be reserved for entry and egress by competitors and the judge.This area may vary by venue.
