A magnetic-induced stiffness changed soft robot drive module includes magnetic-induced stiffness changed layer, two-degree-of-freedom pneumatic driver, magnetic core and sealing fixing device. The magnetic-induced stiffness changed layer and two-degree-of-freedom pneumatic driver are printed and formed. The magnetic core can be deformed together with the driver, and a magnetic field can be generated when it is energized. After the magnetic core is installed into the two-degree-of-freedom pneumatic driver, then assembled with the sealing fixing device, a soft robot drive module with one end fixed is finished. The magnetic-induced stiffness changed layer has the fast, reversible and controllable stiffness adjustment ability under the action of electromagnetic field. As its hardness is greater than that of the two-degree-of-freedom pneumatic driver and its position is outside the air cavity, the two-degree-of-freedom pneumatic driver can be restricted from over-expansion and over-extension in the axial direction, making its pneumatic bending deformation controllable.
