  • Soft grip unit, grip device comprising same, and driving method of grip device
    Patent number: 12128548
    Abstract: In a soft grip unit, a grip device having the soft grip unit, and a driving method of the grip device, the soft grip unit includes a flexible cover, a particle, a negative pressure generator and a flexible supporting part. The flexible cover has a gripping surface on which a target object is attached and a reference surface coupled with the gripping surface. The particle is received by the receiving space, and transformed corresponding to a shape of the target object. The negative pressure generator is connected to the flexible cover. The negative pressure generator absorbs an air of the receiving space to contract the flexible cover. The flexible supporting part is tightly attached to the reference surface, and transformed at the same time when the flexible cover is pressurized and transformed by the target object.

  • SOFT ACTUATOR HAVING COOLER, WEARABLE ROBOT HAVING THE SAME, MASSAGE DEVICE HAVING THE SAME, AND METHOD FOR CONTROLLING THE SAME
    Publication number: 20220213875
    Abstract: In a soft actuator having a cooler, a wearable robot having the soft actuator, a massage device having the soft actuator, and a method for controlling the soft actuator, the soft actuator includes a heat reaction member, a cooling part and a controller. The heat reaction member is configured to be contracted or relaxed according to a temperature change. The cooling part includes a cooling surface disposed at the heat reaction member, and a heating surface disposed opposite to the cooling surface. The controller is configured to control a power supply part so that a power is blocked to be supplied to the heat reaction member and the power is supplied to the cooling part, when the heat reaction member is changed to be a relaxation state.
