Unbeatable Rock-Paper-Scissors robot developed in Japan
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 - as the game is known in Japan - is even faster than the one University of Tokyo researchers unveiled 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.
