Superfast rock-paper-scissors robot 'wins' every time
Matthew Wall, BBC, 4 November 2013
A robot developed by Japanese scientists is so fast it can "win" the rock-paper-scissors game against a human every single time.
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.
