Robot wins rock-paper-scissors using split-second reaction time

TOKYO, Nov. 4 (UPI) -- Members of a University of Tokyo team said they developed a robot that wins every game of rock-paper-scissors by employing split-second reflexes.

The team from the university's Ishikawa Oku Laboratory said the Janken robot, named for the game's Japanese name, uses high-speed recognition and reaction to respond to its opponent's throw so quickly that the human eye perceives it to be forming hand shapes at the same time as a human opponent, the BBC reported Monday.

The scientists said the robot reacts in a single millisecond, faster than the 20 milliseconds required by an earlier model unveiled in 2012.

The robot's creators said they specialize in a range of technologies, including a discipline known as "sensor fusion," which aims to mechanically replicate and improve upon the human senses.
