ABSTRACT:
A gripping actuator comprises a plurality of flexible cylinders arranged adjacent to one another. The inside of each of the flexible cylinder is divided into a plurality of pressure chambers with partition walls that extend axially inside the flexible cylinder. The actuator has a pressure adjuster for adjusting pressures in the respective pressure chambers of the flexible cylinders so that the flexible cylinders may operate at individual degrees of freedom in achieving cooperative motions.
