A network type pneumatic soft actuator is designed with silica gel material. The soft actuator can realize bending deformation under ventilation condition. The driver mold was designed, and the prototype was made. The static experiment and finite element simulation of the actuator were carried out. The results show that the soft actuator has good flexibility and flexibility, and the maximum bending angle can reach 323 degrees. This research lays a foundation for the further application of the software driver.
