Hmmm, this is interesting. An article on an international robot competition being held in San Francisco has this to say: "The competitions seemed to break down along cultural lines. The Japanese robots reigned supreme when it came to sumo-wrestling, while the European teams showed off their skills on the football pitch. Some robots are designed to intimidate. As for the American machines, they specialised in demolishing the living hell out of each other in one-on-one robot combat. " Comments, anyone?
