Japanese scientists have created the Janken robot—meant to best any human opponent in a game of Rock-Paper-Scissors. Janken uses a robotic “eye” to quickly determine what his challenger will throw next. He reacts and flexes the fingers of his robotic hand before the human hand can complete its motion and victory is his. He is an improved version with a one-millisecond reaction time and a 100% winning record. He gets his name from the Japanese name for the game. But Janken is meant for more than “one-upping” us. Creators say the same quick reactions could help robots one day more seamlessly work alongside of us.
