A Small Size robot soccer game takes place between two teams of six robots each. Each robot must conform to the dimensions as specified in the F180 rules: the robot must fit within a 180 mm diameter circle and must be no higher than 15 cm. The robots play soccer with an orange golf ball on a green carpeted field that is 9 m long by 6 m wide.

All objects on the field are tracked by a standardized vision system that processes the data provided by four cameras that are attached to a camera bar located 4 m above the playing surface. The vision system – called SSL-Vision – is an open-source project maintained by the league’s community.

Off-field computers for each team are used for the processing required for coordination and control of the robots. Communications is wireless and uses dedicated commercial radio transmitter/receiver units.

About the Humanoid League

In the Humanoid League, autonomous robots resembling humans in their physical structure and sensory capabilities compete in soccer matches. Unlike their counterparts in other leagues, these humanoid robots can’t rely on non-human-like range sensors to simplify the tasks of perception and world modeling. Besides the thrilling soccer matches, the league also hosts technical challenges. Research topics explored in the Humanoid League include dynamic walking and running, kicking the ball while maintaining balance, visually perceiving the ball, the field, and other players, self-localization, and team collaboration.

Competitions

The robots are categorized into three distinct size groups: KidSize (height ranging from 40-90cm), TeenSize (height between 80-140cm), and AdultSize (130-180cm in height). In the KidSize soccer division, teams of four highly agile and autonomous robots compete against each other. From 2010 onwards, the TeenSize soccer category features dual robot teams engaging in intense competition. In the AdultSize soccer league, a striker robot initially competes against a goalkeeper robot, and then they switch roles to compete again.

Rules

The Technical Committee, which includes members elected by the teams, is responsible for formulating the rules of the Humanoid League. Input and votes from the team leaders, collected during the annual meetings held at RoboCup events, significantly influence the evolution of the rules. The committee encourages suggestions, corrections, and feedback, which can be shared directly with the Technical Committee or via the league’s mailing list.
