Small Size Robot League

A Small Size robot soccer game takes place between two teams of five robots each. Each robot must conform to the dimensions as specified in the F180 rules: The robot must fit within a 180mm diameter circle and must be no higher than 15cm unless they use on-board vision. The robots play soccer on a green-carpeted field that is 4.9m long by 3.4m wide with an orange golf ball. Robots come in two flavors, those with local on-board vision sensors and those with global vision.

Global vision robots, by far the most common variety, use an overhead camera and off-field PC to identify and track the robots as they move around the field. The overhead camera is attached to a camera bar located 4m above the playing surface. Local vision robots have their sensing on the robot itself. The vision information is either processed on-board the robot or is transmitted back to the off-field PC for processing.

An off-field PC is used to communicate referee commands and, in the case of overhead vision, position information to the robots. Typically the off-field PC also performs most, if not all, of the processing required for coordination and control of the robots. Communication is wireless and typically uses dedicated commercial FM transmitter/receiver units.
