In Japan, scientists have developed a super-fast, unbeatable rock-paper-scissors robot. If against a human, it wins every single time.
This is the second version designed- the first one was revealed in June 2012. The second version is even faster than the original one and completes its chosen hand shape almost at the same time as the human hand.
This clever contraption 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 random shape which is what the rules of the game are.
But even if it does cheat it is a wonder in technoligy all the same.
