RoboCup Federation

What it is

RoboCup is an international robotics initiative and competition built around a single long-term target: robot soccer players good enough to beat a human World Cup champion team. The RoboCup Federation's official history gives exactly that as the aim of the initiative ^[1]. Because the games and the conference are held together ^[1], the project works both as a tournament and as a place where researchers present and compare methods.

How it started

The project began in Japan. In June 1993 a group of researchers — among them Minoru Asada, Yasuo Kuniyoshi and Hiroaki Kitano — decided to launch the competition ^[1]. When researchers outside Japan asked for an international joint project, the effort was renamed the Robot World Cup Initiative, RoboCup for short ^[1]. In September 1993 the initiative was announced publicly for the first time, and specific regulations were drafted ^[1].

Several earlier lines of work fed into it. Itsuki Noda, at the ElectroTechnical Laboratory in Japan, used soccer as the setting for multi-agent research and developed a dedicated simulator ^[1]; that simulator later became RoboCup's official soccer server ^[1]. Minoru Asada's laboratory at Osaka University, and Manuela Veloso and Peter Stone at Carnegie Mellon University, had also been working on soccer-playing robots ^[1].

The first competitions

The plan was announced at an AI conference. At IJCAI-95 in Montreal in August 1995, the announcement was made that the First Robot World Cup Soccer Games and Conferences would be organized together with IJCAI-97 in Nagoya ^[1]. A trial event came first: Pre-RoboCup-96 took place during IROS-96 in Osaka from November 4 to 8, 1996, with eight teams in a simulation league ^[1]. A simulation league is the software side of the project: teams write programs whose virtual players play the match inside a shared simulator, instead of building physical robots. The first official RoboCup games and conference followed in 1997, with more than 40 teams and more than 5,000 spectators ^[1] — a large jump from the eight teams of the trial.

Where it sits in the field

RoboCup sits where robotics, multi-agent systems and artificial intelligence meet. A soccer match is a demanding test for a machine: players have to read a changing scene, decide quickly, coordinate with teammates and cope with opponents, and the rules make the outcome easy to measure — the scoreline is the result. Framing the work as a game with a fixed, ambitious goal gave many laboratories a shared benchmark and a common annual meeting. One set of rules and one official server also mean that different teams' work can be placed side by side and compared.

The history also shows how much of the project's infrastructure came out of individual research. Noda's simulator, written for his own multi-agent experiments, became the shared soccer server used by simulation teams ^[1]; the name and the regulations were settled in the same months as the first public announcement ^[1]. The growth from a trial with eight simulated teams to a first official event with more than 40 teams and thousands of spectators ^[1] is the arc the federation itself highlights.
