“RoboCup is an international robotics competition founded in 1997. The aim is to develop autonomous soccer robots with the intention of promoting research and education in the field of artificial intelligence. The name RoboCup is a contraction of the competition's full name, «Robot Soccer World Cup», but there are many other stages of the competition such as «Search and Rescue» and «Robot Dancing»”. – Wikipedia
