This application provides a snake-like winding soft actuator, which aims to solve the problem that the soft robot is still in the research stage and needs to be further expanded. It includes an elastic bellows, a strain-limiting layer, an elastic expansion layer, a fixed connector, and an air pipe for connecting with an air source. The present application provides a novel serpentine winding actuator, which includes two types: a winding actuator with a strain-limiting layer and a winding actuator without a strain-limiting layer. The serpentine winding actuator with strain-limiting layer relies on the strain-limiting layer and the elastic stretch layer to determine the winding performance, and can quickly and efficiently wind the slender rod tightly. As the inflation pressure increases, the serpentine winding actuator will wind tighter and can lift 1.3kg objects. The winding actuator without the strain-limiting layer is lighter and softer, and only depends on the fixed direction of the elastic stretching layer to determine the winding method of the actuator, which can also wind and lift objects.
