OPENTECHNICAL PUBLICATION OT-2026-000002962 Hand and robot system Published: 2026-09-15T19:16:25.158997Z Permanent URL: https://opentechnical.org/p/OT-2026-000002962 Categories: Robotics & Automation > Robot Architectures ------------------------------------------------------------------------ ABSTRACT A hand 100 includes a hand body 2 , a gripper 3 that grips a workpiece, a coupler 4 that couples the gripper 3 to the hand body 2 such that a relative position of the gripper 3 to the hand body 2 is changeable, and a lock 9 that locks movement of the coupler 4 . The lock 9 switches, by an opening/closing action, between a locked state where the lock 9 locks movement of the coupler 4 by contacting the gripper 3 and an unlocked state where the lock 9 unlocks movement of the coupler 4 by separating from the gripper 3. ------------------------------------------------------------------------ OpenTechnical publication OT-2026-000002962 Published 2026-09-15T19:16:25.158997Z https://opentechnical.org/p/OT-2026-000002962
