Researchers in Tokyo have created the world's most formidable rock, paper, scissors opponent.
Invented at the University of Tokyo, the Janken robot can beat a human at the classic game with 100 percent accuracy.
How does it do it?
Instead of using prediction as a human would, the bot uses high-speed recognition and reaction, according to BBC.
The robot can recognize the shape a human hand is making in just one millisecond and display its own counter-move before the person is able to finish a gesture. This vision recognition is reportedly impossible for the human eye to detect so the robot has an advantage in the game.
Though the robot was invented in 2012, this year researchers focused on making it an even better cheater. Last year the delay was about 20 milliseconds, which mean the simple robotic hand would complete the gesture right after the human one. Now that the time has been cut down to one millisecond. No delay is detectable.
While a robot that can beat opponents in a schoolyard game may seem like an unusual project, researchers claim it is a small but important step in robotic advancement.
According to a statement by the University of Tokyo, "this technology can be applied to motion support of human beings and cooperation work" between humans and robots "without time delay."
