UNDATED (CNN) -- If you like to play rock-paper-scissors and you happen to be a masochist, have we got an opponent for you. There is a robot that's a winner, always.
When robots start playing rock paper scissors, humanity may find itself caught between a rock and paper because humans lose to this machine 100 percent of the time.
It was designed at Ishikawa Oku laboratory at the University of Tokyo. The only way to beat this thing is to invent new rules, as they did on Friends when Joey invented fire, because it beats everything!
So how does the robot do it? Well a high speed camera recognizes which shape the human hand is making and within one millisecond chooses the gesture that trumps it.
Some say it cheats, cheats really fast. It's like a card shark that sees your hand. But what about the folks who organize championship tournaments.
What does the world rock paper scissors society think of the robot? Douglas Walker says, "It's extremely impressive."
Walker doesn't consider it cheating. He says humans try to determine what sign an opponent will throw. The highest level rock paper scissors players actually do look at people's hands.
For humans rock paper scissors resonates from childhood but we're not sure what a rock scissors robot is good for practically speaking. The same Japanese lab has designed cloth folding and pen spinning and egg-catching and rope knotting robots.
The rock paper scissors society did have one criticism of this robot's vertical paper sign, which is technically bad form.
Instead of the vertical handshake' motion, the correct is to have your hand be flat and horizontal with the ground.
