As a research in sensor fusion a team from Ishikawa Oku Laboratory developed a janken (rock-paper-scissors) robot with 100% winning rate as one example of human-machine cooperation systems.
The robot realizes 100% winning rate by high speed ecognition of high speed vision and high speed acuation of a robot hand. In the first version, a final shape of the robot is delayed about 20ms after the finished shape of a human hand. In the second version, a final shape of the robot is completed almost same time of the finished shape of a human hand.
