It's like a mechanical version of Misato Katsuragi or that girl from Hunter x Hunter's Trick Tower. Scientists at Ishikawa Oku Laboratory have developed a janken (rock-paper-scissors) robot with a 100% winning rate to demonstrate human-machine cooperation systems. First chess, then janken, then the world.
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.
