The invention relates to a creeping device of a robot, in particular to a spring wheel-leg creeping device of a bionic amphibious robot. The spring wheel-leg creeping device comprises a wheel leg, a lock nut, a sleeve, a compression spring and a rotation shaft, wherein one end of the rotation shaft is connected with a drive unit installed in the bionic amphibious robot, and the rotation shaft is driven by the drive unit to rotate; one end of the sleeve is connected with the other end of the rotation shaft, and the sleeve is driven to rotate by the rotation shaft; the other end of the sleeve is connected with the wheel leg through the lock nut, and the wheel leg slides relative to the sleeve in a reciprocating manner; the compression spring for achieving the cushioning effect is accommodated in the sleeve; and two ends of the compression spring are abutted against the wall of the sleeve and the wheel leg is arranged in one end of the sleeve in an insertion manner. The spring wheel-leg creeping device of the bionic amphibious robot has the characteristics of good stability in movement, high crawling capability, compact structure, flexibility and controllability, high environment adaptability and the like.
