Rock paper scissors robot
A robot that always wins the game of Rock Paper Scissors - or Scissors Paper Stone - has been invented by scientists in Japan.
Researchers at the University of Tokyo reckoned they've developed a way for it to win every time.
It uses a extremely high-speed vision to analyse what the human hand is doing first.
It takes just one millisecond - a thousandth of one second - and then does a different move to beat it!
