Soft crawling robot driven by shape-memory alloys

The invention relates to the field of driving of soft robots, in particular to a soft crawling robot driven by shape-memory alloys. Taking the forward motion direction of the robot as the axis, the soft crawling robot driven by the shape-memory alloys winds shape-memory alloy wires evenly in surface structure materials which form the soft robot; conductive hyperelastic materials connect the shape-memory alloy wires in the surface structure materials with a wireless transceiver module; the conductive hyperelastic materials are embedded in a surface structure; the surface structure is made of polymer elastic materials capable of elastic deformation; and liquid cavities are positioned in soft unit cells. The shape-memory alloy wires can generate heat when being energized so as to allow martensite to reach a phase transition temperature to contract and the shape-memory alloy wires can cool and return to an extension state when being de-energized so as to allow the soft unit cells to returnto original shapes; and
