2011 is the 2500 year anniversary of the marathon and the international year of chemistry. Combining marathon with chemistry, the game is to build a fuel cell powered robot that can move continuously for the full 2 minutes 15 seconds.

I know what you are thinking, that's almost as dull as Lunacy but for the robots that stop moving, an onboard motion sensor triggers an explosive charge (air bag module) and the robot gets blown up. Too bad for them but very exciting for the spectators. Bring plenty of spare parts next year.
