The RoboCup Standard Platform League is a RoboCup robot soccer league, in which all teams compete with identical robots. The robots operate fully autonomously, i.e. there is no external control, neither by humans nor by computers. The league is based on Aldebaran's Nao humanoids. Teams compete with their five 53cm height robots, which are able to communicate with each other by the wireless network. Robots are able to use two cameras, placed on their face in order to recognize objects in the field. As there is no difference in robots hardware, the team with more optimized software and intelligence is the winner.
