RoboCup is an international competition with the aim to develop and improve intelligent robots. It is the intention to improve the robots in such a way that they are able to compete with and to triumph over the world football champions until 2050.
Meanwhile not only football playing robots compete with each other but also domestic robots.
Also there are competitions with robots acting as rescue man. Therefore they need to have the ability to move and orientate in highly complex environments.
Another idea is to use robots as a kind of learning help to increase motivation for kids.
