One of my favorite games … Rock-Paper-Scissors. And who would have thought that a robot can beat man in this superfast game of wit.
“A robot developed by Japanese scientists is so fast it can win the rock-paper-scissors game against a human every single time. The Janken robot – named after the game’s Japanese name – is a faster version of one unveiled by University of Tokyo researchers in June 2012.
Version two completes its chosen hand shape almost at the same time as the human hand. It uses high-speed recognition and reaction, rather than prediction. Technically, the robot cheats because it reacts extremely quickly to what the human hand is doing rather than making a premeditated simultaneous action as the rules state.
Taking just one millisecond (ms) – a thousandth of a second – to recognise what shape the human hand is making, it then chooses a winning move and reacts at high speed. Version one completed its shape 20ms after the human hand; version two finishes almost simultaneously.”
