tournament a human team consisting of representatives of the International RoboCup Federation plays a match against the winner of the RoboCup MSL competition. To prepare for major changes in rules or in specifications of the arena, at every RoboCup a side-event is organized. During this 'technical challenge,' teams are asked to focus on a certain subtask within the game of soccer. The 2006 competition's challenge was to demonstrate that a team of robots could pass the ball. More recent challenges have focussed on robot-robot cooperation without WiFi connection and playing soccer on uneven terrain (i.e., artificial grass instead of a carpet).
