While robots are still quite a ways away from being able to challenge humans in sports like soccer, it looks like at least one company has managed to create a robot that's able to prevail in one somewhat athletic activity: air hockey. According to Nuvation, its otherwise unassuming robot arm here can not only hold its own against its human opponents, but beat them about 90 percent of the time. That, as you might have guessed, is done with the aid of an optical sensor that's programmed to follow the conveniently shiny puck and react like an old air hockey pro. Still skeptical? Check it out in action in the video after the break.
