Game-playing robots and other cool stuff
Remember the game "rock, paper, scissors"? Well, if you plan on playing against a robot, expect paper to cover rock every time.
Developers at the University of Tokyo invented a high-speed robot hand that can recognize the motion of a human hand. Whether the person's hand signals scissors, rock or paper, the robot hand uses its ultrafast vision to always cut, break or cover its opponent—all in a matter of a millisecond!
Looks like the "Janken robot" will be the undefeated champion in this game from now on.
