SA Sumo Challenge

SA Sumo Challenge

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.

Divisions

There are three divisions of the sumo challenge, each with slightly different rules and regulations.

Standard Sumo
Open Sumo
Spike Sumo

For RCJSA Sumo Standard Challenge, all participants shall use the standard EDUCATION or COMMERCIAL LEGO Mindstorms EV3, NXT, Spike or Inventor Kit. The sumo bot can have only 1 EV3, NXT or Spike controlling it.

  • The weight of the robot cannot exceed 800 grams.
  • Each robot may only use up to 2 motors for driving and 1 motor for lifting. Robots can have up to 2 touch sensors for bump sensing, 1 colour/light sensor, 1 ultrasonic sensor, and 1 Gyro sensor.
  • Standard Sumo robots must fit within an open-top 210mm (L) x 210mm (W) x 210mm (H) frame, (including all capturing, lifting mechanisms must be fully extended).

 

An Open sumo bot can be made from any kit or material. Including LEGO, Makebots, Edisons, BBC Microbits, etc. or homemade (including 3D Parts). The sumo bot can only have one brain controlling it.

  • Each robot may only use up to 3 motors for driving, 1 motor or electronic actuator for lifting and flipping. Up to 2 touch sensors for bump sensing, up to 2 colour/light sensors, up to 2 ultrasonic or infrared sensors, 1 Gyro sensor and 1 pixy camera.
  • The weight of an Open sumo robot cannot exceed 1.5Kg.
  • 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).

As a new product we will be allowing students to compete in a stand-alone RCJSA Spike Sumo Challenge, all participants shall use the standard EDUCATION or COMMERCIAL Spike Kit. The Robot Inventor Kit 51515 can also be used in this division.

  • The weight of the robot cannot exceed 600 grams.
  • Each robot may only use up to 2 motors for driving and 1 motor for lifting. Robots can have up to 2 touch sensors for bump sensing, 1 colour/light sensor and 1 ultrasonic sensor.
  • Standard Sumo robots must fit within an open-top 210mm (L) x 210mm (W) x 210mm (H) frame, (including all capturing, lifting mechanisms must be fully extended).

The Sumo Field

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.

Rules

Make sure you read the latest rules for this challenge. These rules can change from year-to-year.
