  • Publication number: 20230121702
    Abstract: A robot traveling device 20 according to one aspect of the present disclosure is arranged on a floor surface. The robot traveling device includes a plurality of bases 21 discretely laid on the floor surface, a rail base 23 installed on the bases, a rail part 27 supported by the rail base, a stand part 29 that is movably supported by the rail part and on which a robot 200 is mounted, and a flexible cable carrier 31 for protecting a cable of the robot. Heights of the bases are determined so that a gap of 50 to 100 mm is provided between the floor surface and the rail base and cable carrier. Accordingly, maintainability is improved without lowering of approachability of workers to the machine tool.
