Abstract: In a soft grip head, a soft grip unit having the soft grip head, and a grip device having the soft grip unit, the soft grip head has a suction pad and the suction pad makes contact with an object. The suction pad includes a sidewall and a plurality of suction cells. The sidewall divides the suction pad into a plurality of spaces, and both ends of each of the spaces are open. A plurality of suction cells is respectively formed by the spaces divided by the sidewall. The suction pad includes a material having a stiffness along an axial direction smaller than a stiffness along a width direction. The suction cells extend along the axial direction, and the width direction is substantially perpendicular to the axial direction.

Abstract: In a soft grip unit, a grip device having the soft grip unit, and a driving method of the grip device, the soft grip unit includes a flexible cover, a particle, a negative pressure generator and a flexible supporting part. The flexible cover has a gripping surface on which a target object is attached and a reference surface coupled with the gripping surface. The particle is received by the receiving space, and transformed corresponding to a shape of the target object. The negative pressure generator is connected to the flexible cover. The negative pressure generator absorbs an air of the receiving space to contract the flexible cover. The flexible supporting part is tightly attached to the reference surface, and transformed at the same time when the flexible cover is pressurized and transformed by the target object.
