  • Patent number: 11108343
    Abstract: A flexible and soft smart driving device comprises a flexible frame, a driving mechanism and a creeping structure. The driving mechanism uses an intrinsic strain of an intelligent soft material to generate a driving force. A creeping structure is used to implement autonomous activities of the flexible and soft smart driving device. The driving mechanism and the creeping structure are attached to the flexible frame. The driving mechanism generates the driving force by contraction and relaxation of a driving membrane. The flexible and soft smart driving device is made from flexible materials and has advantages of good creeping speed, flexible control, small noise and high human body compatibility.
    Type: Grant
