A robot fighting contest that draws huge crowds in Japan each year has highlighted sophisticated technological trends in robotics, experts say. The 2004 Robo-One contest, held in Kawasaki, central Japan on 8 August, drew hundreds of spectators. The event is inspired by the sport K-1, a combination of kick-boxing other martial arts that is popular in Japan. But the contestants are remote controlled robots constructed and operated by robotics enthusiasts and experts. Robots battle it out one-on-one for the title of overall Robot-One champion. In each bout a winner is declared if a robot is unable to stand within ten seconds of falling over, or if one freezes up or falls from the fighting platform. The competition also includes a frenetic multi-robot brawl known simply as "The Rumble". Eight robots scrap it out with the last one standing declared the winner.
