The invention relates to the field of robots, in particular to a walking structure of a simulation robot. The walking structure of the simulation robot adopts a method of adding a driving motor on both sides of a supporting mounting member and fixing a rotating shaft end with a profiling supporting member. Through the alternate rotation of driving motors on both sides, a marching-type walking of the profiling supporting member of human leg simulation is realized, and a conventional roller or crawler type walking method is avoided. A mounting assembly of connection member, mounting member and rotating member are sequentially added on both sides of a mounting base. A supporting mounting member is connected through a rotating shaft and a rotating groove, so that the supporting mounting membercan rotate around the rotating shaft. An assembly of rotating mounting member, rotating shaft and electric telescopic rod are respectively added to the bottom surface of the supporting mounting member and the bottom surface of the mounting member. The angle between the supporting mounting member and the mounting base is adjusted by the expansion and contraction of the electric telescopic rod, sothat people can use it conveniently.
