Rock-Paper-Scissors Robot Will Beat You 100% Of The Time

Paul O'Flaherty

This Janken (rock-paper-scissors) robot has a 100% success rate over humans achieved by employing a high-speed camera to recognize the position of the human hand and have the robot play it’s move in 1 ms, which is faster than the human eye can see.

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.

I want to see how this robot fairs playing Rock-paper-scissors-lizard-Spock.
