The RoboCup Standard Platform League (SPL) is one of several leagues within RoboCup,[1] an international competition with autonomous robotic soccer matches as the main event.
[3] The robots operate fully autonomously; i.e., there is no remote control by either humans or computers during the games.
Initially a small number of teams were invited to join the league.
In 2002, the league was opened and teams were allowed to apply through a qualification process.
After Sony announced that it would discontinue production of the AIBO in 2006, the League searched for a new platform and decided on the Aldebaran Robotics humanoid NAO.
