RoboCup
RoboCup is an annual international robotics competition proposed and founded in 1997. The aim is to promote robotics and AI research, by offering a publicly appealing, but formidable challenge. 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 "RoboCupRescue", "RoboCup@Home" and "RoboCupJunior". In 2015 the world's competition was held in Hefei, China. RoboCup 2016 will be held in Leipzig, Germany.
The official goal of the project:
"By the middle of the 21st century, a team of fully autonomous humanoid robot soccer players shall win a soccer game, complying with the official rules of FIFA, against the winner of the most recent World Cup."
