Abstract
The present disclosure relates to a 4D printed gripper with flexible finger joints and a trajectory tracking control method thereof. The 4D printed gripper with flexible finger joints includes: a palm unit and five finger units connected to the palm unit, where each finger unit includes two flexible finger joints and two phalanges; each flexible finger joint is divided into one upper layer and one lower layer of liquid crystal elastomer (LCE), and each LCE is used to implement a bidirectional bending movement of the finger unit. The present disclosure can precisely control the gripper with flexible finger joints.
