ALSO I WOULD LIKE THE ABILITY TO BRAKE THE MOTORS, SINCE OUR SLOW AND STEADY HIGH TORQUE DESIGN.
Sumo RobotRemote-Controlled - Middle School, High SchoolSelf-Controlled - Middle School, High School, Post-SecondaryContest DescriptionThe Sumo Robot Contest requires a student team to build a self-propelled, remote controlled orsensing robot, designed to force another Sumo Robot outside a ring. The competition ring will be asquare painted flat black, measuring 15’ 2” across. This inside square is surrounded by a two-inch(2”) wide, painted or taped, flat white ring. Another white one-inch (1”) wide, line will surround theinner ring with 2 inches (2”) between them. When any part of the Sumo crosses completely overthe 1” white outer ring it will lose the heat.Rules1. The Sumo must be powered by electrical storage batteries. No other power sources will beallowed. These batteries must be sealed and all possible precautions must be incorporated intothe design to prevent accidental spills. The judges may disqualify any design that is determinedto be unsafe.2. The Sumo must use sensing devices to govern the motion of the Sumo and must use sensorsto either detect other Sumo and/or the edge of the white line. (The remote-controlledlightweight robots do not require sensors.)3. The Sumo Robot must fit inside a 24” x 24” x 24” space. Any robot entered that does not meetthe size requirement by the end of the device evaluation will be disqualified. Device evaluationwill take place at the time indicated on the Official Schedule4. The Sumo drive wheels must be non-destructive to the playing surface.5. All robots are subject to the final approval of the NRC staff and judges. Any robot that isdeemed too dangerous to other robots or competitors will be disqualified.6. The contest has two sections: (1) Lightweight section in which the Sumo must be remotecontrolled and cannot exceed 50 pounds and (2) Heavyweight section in which the Sumo mustbe self controlled and cannot exceed 125 pounds. Each robot may only enter one section.7. Weight may not be added after the Sumo has been weighed and evaluated by the judges.8. Double elimination contests will decide the winner of each section.9. At the beginning of each competition, with the robot deactivated, the Sumo handler(s) willposition their Sumo one foot apart as instructed by the judges. Four start configurations will bepossible:At the command of the judge/facilitator, the handler(s) will activate their robot.10. All robots must have a visible RED locking emergency stop button on top of the robot in case ofa malfunction. (New for 2012)11. All lightweight entries must have with the ability to change between at least 2 differentfrequencies. We recommend that teams invest in 2.4 GHz radios and receivers such asFutaba’s FASST system. (http://2.4gigahertz.com)12. When any part of one Sumo completely crosses the outer white line, the other Sumo isdeclared the winner of that engagement.13. If both Sumos leave the ring at the same time, a "non-contest" is declared and the two Sumosare repositioned and the contest begins anew.14. If, after three minutes, no winner is declared, the two Sumos are repositioned and the contestbegins anew. If no winner is declared after this second encounter, the judges shall declare awinner based on action observed within the ring and on the design of the selected Sumo.15. A pit area, with access to 110-volt standard outlet, will be provided.16. At the conclusion of each match the winning robot must be weighed to ensure that legal weighthas been maintained. (New for 2012)17. Decisions of the judges are final and binding.
