The invention discloses a biped-walking dining car pushing robot which comprises an upper body structure, a back, a lower body structure and a dining car, wherein the upper body structure comprises a main frame having an appearance simulating the shape of the upper body of a human body, and the main frame comprises a head part, shoulder parts and a chest part; the dining car comprises a framework body, three carrier layers are alternately arranged on the body uniformly from top to bottom, and wheels are arranged at four corners of the bottom of the body; a handrail is connected with the top of the rear part of the body; a double-stable dining delivery device is carried in every two carrier layers; and the lower body structure is arranged in a bilaterally symmetric manner, and comprises thigh structures, shank structures and foot structures. The biped-walking dining car pushing robot can simulate the human body to push the dining car and walk, simulate the knee bending action of the human body as well as simulate the action that the leg with a bent knee walks forward and the other leg does not walk temporarily, and is stable in dining delivery. The biped-walking dining car pushing robot has a relatively simple structure, is convenient to process and manufacture, has relatively low cost, and is suitable for restaurants for saving labor force and attracting more diners.
