You all know the children's game stone-paper-pair of scissors. Well there is someone, or rather something that you cannot beat. No matter how skilled and fast you are you will have no luck competing against the robot developed just for this game.
His name in Japanese is "Janken" robot and means stone-scissors-paper. The robot is scheduled to play the toy with people and win them. So simple. He uses high-speed computer vision to capture the opponent's movements and can guess the answer.
Think you're fast enough to beat the robot? Well, Janken can detect your movements in just a fraction of a second and make its own move in just 20 milliseconds. The human eye it takes 40 milliseconds to see and process an animation picture.
But better to see it in practice.
