Robocup Junior South Australia (RCJSA) Sumo is a head to head competition where two autonomous robots try to push or flip the other out of a circular ring.
Sumo robots must be fully autonomous, so they need to employ a variety of sensors to search for the opponent, push them out, and stay inside the playing area.
Students will need to come up with creative programming / build to outsmart the opposition.
Due to its ease of introduction, many students choose to use LEGO kits (Ev3 or NXT), Spike Prime or Inventor to build and program their robots. Other students select alternative platforms and even build their own microprocessor robots from basic electronic components. A range of sensors can be attached to all of these platforms, including electronic compasses, sonars, light sensors, infrared sensors, actuators and cameras.
There are three divisions of the sumo challenge, each with slightly different rules and regulations.
All participants can use a single standard EDUCATION or COMMERCIAL LEGO kit. This may be either NXT, EV3, Spike Prime or Robot Inventor 51515.
Note: Tracks are not permitted in Featherweight Sumo
Participants can only use the kits proprietary software. The program must be stored and run from the brick.
The weight of the robot cannot exceed 600 grams.
Each robot may only use:
4 wheel drive systems are not permitted
All robots must fit within an open-top 210mm (L) x 210mm (W) x 210mm (H) frame, (including all capturing, lifting mechanisms at its full extension).
All participants can use a single standard EDUCATION or COMMERCIAL LEGO kit. This may be either NXT, EV3, Spike Prime or Robot Inventor 51515.
Note: Tracks are not permitted in Standard Sumo
Participants shall only use the software provided with those kits. The program must be stored and run from the brick.
The weight of the robot must be between 700 – 900 grams.
Each robot may only use:
3D printed lego bars/pieces can be used, however they CANNOT form scoops or walls
4 wheel drive system is not permitted in Standard
All robots must fit within an open-top 210mm (L) x 210mm (W) x 210mm (H) frame, (including all capturing, lifting mechanisms at its full extension).
The robot can be made from any kit or material. The robot can only have one controller (brain) controlling it.
Each robot may only use:
Participants can only use the software provided with kits or text-based software. Robots may be remotely started if the program is stored on a Device or PC. Once started the device or PC isn’t to be touched unless a restart has been called or instructed by the referee.
The weight of the robot must be 1000g or greater
The use of custom made 3D printed, and laser cut pieces are permissible. These CAN form scoops or walls
All robots must fit within an open-top 250mm (L) by 250mm (W) x 210mm (H) frame, (including all capturing, lifting mechanisms must be fully extended).
The Arena – is the area where the sumo robots will compete.
The arena will be a circular ring 1000 to 1200 mm in diameter with a 50 mm white border around the ring’s perimeter. The Arena’s playing surface can be raised up to 30 mm in height for the Open division.
Starting Lines may be included, (dimensions are 200 mm long, 20 mm wide and 200 mm apart).
The materials needed to make a field are low-cost and easily found at your local hardware store.
Make sure you read the latest rules for this challenge. These rules can change from year-to-year.
