Snakelike wound software actuator
The invention provides a snakelike wound software actuator, which is aimed at solving the problem that a software robot is still in a research stage and needs to be further expanded. The snakelike wound software actuator comprises an elastic corrugated pipe, a strain limiting layer, an elastically stretchable layer, a fixed connecting piece, and an air passage pipe for connection with an air source. The novel snakelike wound actuator provided by the invention covers a wound actuator with the strain limiting layer and a wound actuator without the strain limiting layer. The winding performance of the snakelike wound actuator with the strain limiting layer is determined by depending on the strain limiting layer and the elastically stretchable layer; the snakelike wound actuator with the strain limiting layer can wind a long and thin rod rapidly and efficiently; and with the increase of inflation pressure, the snakelike wound actuator winds an object more tightly and can lift a 1.3kg object. The wound actuator without the strain limiting layer is relatively light and soft; the winding manner of the actuator is determined only by depending on the fixed orientation of the elastically stretchable layer; and the wound actuator without the strain limiting layer can also wind and lift the object.
