LIVE robot marathon! via CNN…

Five robots are racing around a room in Osaka, Japan, in what organizers call the world’s first robot marathon. The robots, entered by companies and universities, will complete a 26.2-mile marathon course by making 423 circuits of a track in a room in Osaka, CNET reports. Robots that fall over will have to get back up on their own, but human pit crews can recharge batteries, according to CNET. Toughness rather than speed will determine a winner among the foot-tall robots, the report says. The event, dubbed Robomarafull, is organized by robot maker Vstone and local government officials.
