Rubik’s Cube Manipulation Using a High-speed Robot Hand

We realized manipulation of Rubik’s cube using a high-speed robot hand with three fingers. The experimental system consists of a high-speed vision and a high-speed robot hand, and the high-speed vision can calculate the center of gravity position and angle of the Rubik’s cube at 500 fps. The manipulation realized in this research is a total of three operations, two kinds of regrasping and one-face turning of the Rubik’s cube. By combining these three operations all the faces can be turned. In the experiment, these three operations were performed in a row in 1 second and we succeeded in 30 continuous operations in 10 seconds.
