Football is generally be played on a ping-pong table or equivalent, around which fences should be placed as well as a goal at each end. The ball is simply a brightly coloured ping-pong ball. Teams are generally between 1 and 3 players and each half of the game is usually 5 minutes long, changing ends at half-time.
A ball-gathering competition could also be played, as seen here, in which teams of Star and Spin Shooter robots score as many goals as possible using a large number of balls.Both the Spin Shooter and the Star Shooter are very simple soccer-playing robots, which cannot hope to compete against the more "professional" software-driven robo-soccer bots such as the MIABOTS.
However, in their own way, these bots can provide a great deal of fun in friendly matches between friends.
