Two teams each place two robots (which they have designed and created) on a playing field. The aim of the game is for each team of robots to play a fully game of soccer. The robots detect the infrared-emitting ball and use this as well as other specialised sensors, such as sonars, compasses and cameras to locate themselves and the opposition's goal. These robots must each be able to fit into a cylinder which is 220 mm in diameter and height.
