Robots and nationality at the ROBOlympics

Clark Boyd of BBC News Online notes that there were some interesting, ahem,
"cultural differences" between the robots at this past weekend's ROBOlympics in San Francisco:

The Japanese robots reigned supreme when it came to sumo-wrestling, while the European teams showed off their
skills on the football pitch. As for the American machines, they specialised in demolishing the living hell out of
each other in one-on-one robot combat.
