  • 4D printed gripper with flexible finger joints and trajectory tracking control method thereof
    Patent number: 11969891
    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.

  • SOFT JOINT GRIPPER BASED ON 4D PRINTING AND CONSISTENCY CONTROL METHOD THEREOF
    Publication number: 20220305668
    Abstract: A soft joint gripper based on 4D printing comprises a palm body and five soft finger units connected with the palm body; each soft finger unit is provided with two soft finger joints and two finger bones; the finger bones are made of 3D printing resin; the soft finger joints are two symmetrical double-layer thin-film soft finger joint actuators; the double-layer thin-film soft finger joint actuator is made of a 4D printing liquid crystal elastomer and a polyimide electrothermal film, and the bending angle of each double-layer thin-film soft finger joint actuator is changed by energization or heating stimulation; and the double-layer film soft finger joint actuator is used to control the soft finger unit to perform reversible bending motion. Accurate control of the soft joint gripper can be realized.
