In this league all teams use identical (i.e. standard) robots. Therefore the teams concentrate on software development only, while still using state-of-the-art robots. Omnidirectional vision is not allowed, forcing decision-making to trade vision resources for self-localization and ball localization.
The league replaced the highly successful Four-Legged League, based on Sony’s AIBO dog robots, and is now based on Aldebaran’s Nao humanoids.
