The Junior Soccer competition involves the use of two autonomous robots, equipped with sensors and actuators that enable the objective of playing football. They are, however, limited in size and may not exceed 22cm in diameter and height. An infrared pulsed signal-emitting ball is now used in the two leagues that currently exist, which differ in the types of field: whilst both fields are 122x183cm, in league (A), the oldest, there are no sidelines or goal lines and playing against the walls is allowed, whereas in league (B), most recent, the ball can be ‘out’ and there is room for replacements. Currently, the field is green with a yellow and a blue goalpost, introducing colour as a possible orientation facility for the robots in the field.
This exciting competition, full of strategies, tactics and goals, also features the usual referee, the only human participant. Additionally, fair play between the teams prevails throughout the game.
