Magnetic control soft gripper

The invention provides a magnetic control soft gripper which is characterized by comprising a coil, a soft magnetic elastomer, a hard magnetic elastomer, a plastic film and magnetorheological fluid. The soft magnetic elastomer is U-shaped, the section of the soft magnetic elastomer is rectangular, the hard magnetic elastomer is tightly attached to the outer side line of the tail end of the soft magnetic elastomer, the coil is wound around the surface of the soft magnetic elastomer and fixedly connected with the soft magnetic elastomer, the plastic film is bonded to the outline of the inner side line of the soft magnetic elastomer, the plastic film and the soft magnetic elastomer form a closed space, and the space is filled with magnetorheological fluid. The soft magnetic elastic body, the hard magnetic elastic body and the magnetorheological fluid form different magnetic circuits by controlling the electrifying direction of the coil, so that the tail end of the gripper generates elastic deformation, the magne
