It was bad enough when robots could win at Connect Four but now roboticists have gone too far. Japaneese scientists have developed a robot that can win at rock-paper-scissors against a human every single time.

The robot reacts to what the human hand is doing instead of making a simultaneous choice so technically it's cheating. The machine only needs a millisecond to recognize what shape the human hand is making and react accordingly.

Sethu Vijayakumar, professor of robotics at Edinburgh University, told the BBC:

These robots are really fast at reaction, but there are scenarios where even a millisecond's delay is not acceptable, such as accident avoidance or virtual stock markets.
