High-Speed Actuator Enables Robot Hand to Grasp Playing Card

"MagLinkage" is a new high-speed actuator, developed at the University of Tokyo's Ishikawa Senoo Laboratory  , that has a small size, low friction, and high torque. The actuator consists of a compact-size DD motor, a low-reduction ratio gear box, and a magnet gear. MagLinkage enables 1ms torque control and sensing, and high-back-drivability motion. A robot hand equipped with the actuator can slide and grasp a thin object like a playing card or sheet of paper on a table. The hand was able to grasp one piece from the pile of cards.

00:00:16 we developed a new actuator mag linkage mag linkage enables one millisecond torque control sensing and high-back drivability motion the impact force can be absorbed by the high-back drivability motion of mag linkage the robot hand equipped with mag linkage can grasp the object on the table with seamless motion the hand can slide and grasp an object on the table
