A robot beating humans in rock-scissors-paper game - video

The Japanese in the University of Tokyo are trying to make a janken (rock-paper-scissors) robot with 100% winning rate. This project is done as an example of cooperation between humans and machines. 


So when the human hand plays one of rock, paper and scissors at the timing of one, two, three, according to the timing, the robot hand plays one of three kinds so as to beat the human being.






This can only happen because the recognition of the human hand can be performed at 1ms with a high-speed vision. Moreover, the position and the shape of the human hand are also 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.
