Middle Size League
In the Middle Size League (MSL) two teams of five autonomous robots play soccer on a 18 x 12 meter indoor field. Each robot is equipped with sensors and an on-board computer to analyse the current game situation and successfully play soccer. Through wireless communication the robots can establish inter-team cooperation and receive all referee commands. No external intervention by humans is allowed, except substitutions. The robots have a height of approximately 80 cm.
