Team Requirements

Each team will consist of two grade 9 - 12 students and one robot.

Team members must be Saskatchewan high school students registered in grades 9 - 12.

Each school is allowed to register 2 teams. Each team must identify if they will be competing in the stock or modified competition as outline in SECTION 6A: ROBOT REQUIREMENTS MODIFIED and SECTION 6B: ROBOT REQUIREMENTS STOCK. Additional teams may be submitted for registration, and will be accepted based on availability of space. Additional team acceptance will be prioritized on a first come, first served basis.

Robot Kit Distribution

Sask Polytech distributes 25 robot kits each year. The robot kits will be distributed upon receipt of the high schools' completed registration form. Schools that have not participated previously will be shown preference provided they apply by the school registration deadline date. After this date, kits will be distributed in the order registrations are received until all kits have been allocated.

Each high school will be provided one robot kit at no charge provided the school sends at least one team that registers to compete. Each kit contains two robots, which means each school could send two teams. If the school does not send a team to compete, the school will be required to pay $565 to keep the kit or return it to Saskatchewan Polytechnic unopened.

Robot Requirements

Modifications to robots will be allowed for teams competing in the modified competition, provided these modifications adhere to the rules specified in SECTION 6A: ROBOT REQUIREMENTS MODIFIED and Section 8: Compliance of the Saskatchewan Polytechnic Sumo Robot Competition Rules. Saskatchewan Polytechnic will not provide extra parts for modifications.

Modifications to robots will not be allowed for teams competing in the stock competition, see section SECTION 6B: ROBOT REQUIREMENTS STOCK and Section 8: Compliance of the Saskatchewan Polytechnic Sumo Robot Competition Rules.

If time permits, robots may be reprogrammed between matches. Teams will supply their own equipment for reprogramming.

Please review the Saskatchewan Polytechnic Sumo Robot Competition Rules.

SumoBot Information

Fingertech Robotics

The 27402 SumoBot Robot Competition Kit by Parallax used in previous competition is no longer available. The new robot kit that will be distributed for future competitions is 32134 Sumobot WX Competition Kit and allows you to build and program two high-quality SumoBot robots designed to wrestle in the mini-sumo competition ring (included in the kit).

The previous robot kits can still be used in the competition. An upgrade kit is available for these robots but is not necessary to compete. The upgrade kit would include a different microcontroller and have an easier programming language. The upgrade kit is available from Parallax (part number 32140)
