  "abstract": "The present invention relates to a walking robot. The robot includes: an X-elongated member; a Y-elongated member; a moving body moving on the X- and Y-elongated members; an X-leg section provided to the X-elongated member, the X-leg section being capable of extending and shortening in the Z-direction; a Y-leg section being provided to the Y-elongated member, the Y-leg section being capable of extending and shortening in the Z-direction; an X-driving mechanism for moving the moving body in the X-direction; a Y-driving mechanism for moving the moving body in the Y-direction; a first Z-driving mechanism for extending and shortening the X-leg section; and a second Z-driving mechanism for extending and shortening the Y-leg section. With this structure, the robot is able to stride over obstructions by extending the X- and the Y-leg sections so as to avoid interference without changing course.",
