Robot football. Technician holding up two Lego robot footballers. Demonstration games between teams of these robots were held at RoboCup-98, the 1998 World Robot Soccer Championships. This international event promotes the development of mobile, co-operative robots through competitive football games. The robots seen here were built with new Mindstorms Lego. They can sense their surroundings through touch and light-sensitive Lego bricks, and have been taught to play football using a programmable brick. RoboCup-98, the second RoboCup, was held in Paris, France. The technician is Luigi Pagliarini, a doctoral student working in the LegoLabs at the University of Aarhus, Denmark.
