Abstract
This link actuation device includes: a proximal end side link hub; a distal end side link hub; and three or more link mechanisms which each couple the distal end side link hub to the proximal end side link hub. Each link mechanism includes: proximal side and distal side end link members, and an intermediate link member. The link mechanism is provided with an actuator which arbitrarily changes the posture of the distal end side link hub relative to the proximal end side link hub. A workpiece is disposed on the proximal end side link hub, and an end effector is disposed in the distal end side link hub so as to face inside of arrangement of the link hubs and perform work onto the workpiece.
