The invention relates to a multi-legged wheeled platform robot. The invention solves the technical problems that the design of the prior art is not reasonable and the like. Include that platform car body, A plurality of running wheels are arranged on the platform car body, A travel wheel body is respectively connected with a wheel body travel driving mechanism, the distance between two adjacent running wheels located in front of and behind the platform car body is fixed, each traveling wheel body is connected with a wheel body lifting and lowering driving mechanism capable of driving the traveling wheel body to lifting and lowering in the vertical direction,A platform car body climbs the step, one of the traveling wheel body is lifted and lowered, and at least two of the remaining traveling wheel body are located on the same horizontal plane and are respectively in contact with the step so as to maintain the platform car body in a horizontal state. The utility model has the advantagesthat each traveling wheel body can independently control the lifting and lowering, the universal direction and the forward and backward reversal functions, and only a few discrete points are needed for the wheels to land, so that the wheels can successfully pass through rugged road conditions, steps and the like, and can easily pass through various complicated natural terrain.
