The walking robot capable of being disassembled and reconstructed includes two rows of parallel food unit structures beside the frame unit, and features that it consists of food unit structures, frame unit structure and active joint unit structures, which may be separated from and combined to other unit structures easily. By means of changing the positions and number of the connecting frames, it is possible to alter the number and configuration of feet in the walking robot and to alter the structure and function of the walking robot. The present invention provides great expansion space for the structure and moving function of walking robot, can replace fault unit and composite new motion structure conveniently, and makes walking robot well fitting different motion environments. The present invention can also simplify structure and control of robot, and lower developing and using cost.
