RobotStadium: Online Humanoid Robot Soccer Simulation Competition

This paper describes robotstadium: an online simulation contest based on the new RoboCup Nao Standard League. The simulation features two teams with four Nao robots each team, a ball and a soccer field corresponding the specifications of the real setup used for the new RoboCup Standard League using the Nao robot. Participation to the contest is free of charge and open to anyone. Competitors can simply register on the web site and download a free software package to start programming their team of soccer-playing Nao robots. This package is based on the Webots simulation software, the URBI middleware and the Java programming language. Once they have programmed their team of robots, competitors can upload their program on the web site and see how their team behaves in the competition. Matches are run every day and the ranking is updated accordingly in the "hall of fame". New simulation movies are made available on a daily basis so that anyone can watch them and enjoy the competition on the web. The contest is running online for a given period of time after which the best ranked competitors will be selected for a on-site final during the next RoboCup event. This contest is sponsored by The RoboCup federation, Aldebaran Robotics, Cyberbotics and Gostai. Prizes includes a Nao robot, a Webots package and a URBI package.
