Foot sole structure of quadruped robot and foot sole replacing method

The embodiment of the invention discloses a foot sole structure of a quadruped robot and a foot sole replacement method, and the foot sole structure comprises a foot sole body which is arranged at the bottom of a shank unit through a fixing part; the plantar body is provided with positioning ribs, and the positioning ribs divide the surface of the plantar body into a plurality of plantar working surfaces; the clamping and locking piece is arranged on the shank unit and used for being matched with the positioning rib so as to limit rotation of the plantar working face. According to the foot sole structure of the quadruped robot, the positioning ribs are arranged on the foot sole body to divide the surface of the foot sole body into the plurality of foot sole working faces, so that the foot sole structure adapts to different road surface scenes, and the utilization rate of the foot sole structure is increased. Meanwhile, a clamping and locking piece is arranged on the shank unit, so that the clamping and lockin
