The earlier version of the robot, which consists of a high-speed vision sensor and a simplistic robot hand, was able to recognize its opponent’s choice of rock, paper, or scissors as their fingers moved into position. The catch was that it took the robot hand another 20 milliseconds to position its own fingers. That minor delay, barely perceptible to the human eye, revealed to anyone with fast enough eyes (really, guys, who does?) that the robot was indeed “cheating”, since it was technically showing its hand slower than the human hand. For the robotics scientists at the University of Tokyo, this was an issue that needed resolving. Now the second and improved version of the robotic hand is able to play its choice in just one millisecond. By recognizing the human player’s strategy earlier, the robot can show its hand at exactly the same time as its opponent.
