# Hand and robot system

## 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.
