No matter how fast you choose your weapon — rock, paper, or scissors — this robot from the Ishikawa Watanabe Laboratory will beat you every time. Thanks for the tip, Mac.
"The third version of the Janken (rock-paper-scissors) robot with 100% winning rate has been developed. In this version, we incorporated the high-speed tracking technologies '1ms Auto Pan-Tilt' and 'Lumipen 2' in order to extend a field of view of the high speed vision system. The inclusion of these technologies additionally enables the system to dynamically track the human hand and recognize its shape in high speed, regardless of where it moves, as well as improves the synchronization between the motion of the robot hand and that of the human hand. Using high-speed vision together with the high-speed actuation of the robot hand enables the robot to achieve a 100 % winning rate."
