The Western Canadian Robot Games (http://www.robotgames.com) is an event entering it's 10th year, where robots and robotics come from all over the world to compete up to 13 events (at peak).
This tool was initially sponsored by the robotics company Solarbotics (http://www.solarbotics.com) as a way to manage the wide array of competitions and competitors. With programming resources at a minimum, the robot games tool has now been released as open source, for any further development by interested parties.
The initial release of the WCRG Competition Tool is now online, for downloading pleasure.
