11370130 · 2022-06-28 · ·

The present invention improves the stability while suppressing increases in the size and heat generation amount of motors used in a hand mechanism. The hand mechanism includes a first driving mechanism for driving a first joint portion of each finger portion and a second driving mechanism for driving a second joint portion of each finger portion, the second joint portion being positioned further away from a tip end portion of the finger portion than the first joint portion. Further, the second driving mechanism is a mechanism having smaller back-drivability than the first driving mechanism. When pressing force is to be exerted on the object from gripping finger portions that are in contact with the object, the motors of the first driving mechanisms are driven to rotate in a direction for bending the first joint portions while the motors of the second driving mechanisms are held in a stopped state.
