Compliant underactuated grasper

This is a robotic gripper designed to hold objects. It uses a cable to move its finger, which is attached to a base. A special magnetic connection allows the finger to detach or bend away if it encounters too much force, protecting the gripper. The invention specifically describes a version with multiple fingers and a thumb, each having compliant joints.

Why it matters: Advances in compliant materials and magnetic components since 2013 could simplify building this design. Growing safety standards for human-robot interaction also increase its relevance.
