DENVER — Japanese researchers have created a robot that is truly invincible — at least within the game of rock-paper-scissors.

Janken, named for the game’s Japanese name, was built at the University of Tokyo.

An eye on the machine recognizes what a human player’s hand is doing before the player can finish doing it.

This allows the robot to throw the winning hand shape no matter how hard its mortal opponent tries to strategize, or even cheat.

The scientists at the Ishikawa Oku Laboratory, part of the University of Tokyo, specialize in “sensor fusion”, which aims to replicate and improve upon human senses using high-speed intelligent robots.
