A method for removing a workpiece from the remainder of the workpiece supported in a bearing plane. The method includes moving the workpiece part, which is clamped between at least one ejector element of an ejection unit and at least one counter-holding element of a counter-holding unit, along a removal direction, and checking whether the workpiece part has been completely separated from the remainder of the workpiece during movement along the removal direction. The method is characterized by reducing or completely canceling the clamping of the workpiece part and subsequently resuming the clamping of the workpiece part if it is determined during checking that the workpiece part has not been completely separated from the remainder of the workpiece.

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.
