Abstract: The present invention discloses a dual-airway bionic snail soft robot, which includes ventral muscular feet, an air pressure controlling device and mucus, wherein the ventral muscular foot includes an upper deformation layer, a lower deformation layer and a strain sensor. Snail ventral muscular feet are simulated by the upper deformation layer and the lower deformation layer to produce wave motion. The strain sensor senses a wave motion state of the soft robot to provide a basis for the air pressure controlling device to output air pressure. In another aspect, snail mucus is replaced with glycerin to produce a suction force and improve crawling efficiency. The designed bionic snail soft robot can move forward, move backward and turn in situ, thereby realizing free movement in a microgravity environment.
