On July 9, Robofoot, École Polytechnique's robot soccer team, headed to Japan to participate for the first time ever in the RoboCup. More than just a game, the RoboCup project is a forum for experimentation and exchange between international researchers working jointly on a central topic: robotics. Between now and 2050, the project aims to design and develop a team of fully autonomous humanoid soccer-playing robots capable of beating the reigning (human) world champs in a match played according to the regulations set out by the Fédération internationale de football.
