RoboCup Junior Soccer

Students are required to design, build, and program two robots to compete in a dynamic game of robot soccer against an opposing pair of robots. 

IMPORTANT NOTICE: In 2018, the Open League will use a passive orange-coloured ball instead of the infrared ball. Please read the 2018 rules carefully regarding this change once they are released. The Standard League and Lightweight League will continue to use the infrared ball as before. The 2018 rules will be available shortly.



  • Standard League (LEGO-only robots)
  • Lightweight League
  • Open League

Due to its ease of introduction to the uninitiated, most students choose to use LEGO Mindstorms 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 been attached to all of the robotic platforms. These can include: electronic compasses, sonars, light sensors, infrared sensors, and cameras. 


Field Construction

In 2017, the fields used for Standard League, Lightweight League and Open League were standardised.  At current, there are no pre-constructed fields available.  Typically, competitions will use fields constructed with green marine carpet with 50mm white cloth tape used for the white boundary lines. An example field construction guide will be posted shortly. 


Simple Simon League

Want to get into RCJ Soccer and don't know where to start? If sufficient interest is shown, states will run a Simple Simon League. This is a cheap introductory league with modified rules. No compass sensors are allowed in this league. Beginner soccer kits are available from Modern Teaching Aids. Check your state or local event page for details.
