Rock-Paper-Scissors Robot Wins With 100% Accuracy (VIDEO)

Rock-Paper-Scissors Robot Wins With 100% Accuracy (VIDEO)

  • Ishikawa Oku Laboratory at the University of Tokyo developed a Janken robot system that can play rock-paper-scissors with a 100% winning rate. The experiment was conducted for the purposes of studying human-machine cooperation systems.

    The laboratory filmed 50 trials, with some in slow motion, showing the speed at which the robot recognized and responded to the human hand signal.

    The website reads:

    Recognition of human hand can be performed at 1ms with a high-speed vision, and the position and the shape of the human hand are recognized. The wrist joint angle of the robot hand is controlled based on the position of the human hand. The vision recognizes one of rock, paper and scissors based on the shape of the human hand. After that, the robot hand plays one of rock, paper and scissors so as to beat the human being in 1ms.

    This technology is one example that show a possibility of cooperation control within a few miliseconds. And this technology can be applied to motion support of human beings and cooperation work between human beings and robots etc. without time delay.


    How do you think this technology can be developed and applied to better society?
