PROBLEM TO BE SOLVED: To provide a robot control device which can accurately detect an attention part of an object on the basis of a picked-up image picked-up by an imaging part.;SOLUTION: A robot control device controls a robot comprising a first movable part moving an object. The robot control device moves an attention part of the object by the first movable part into a first depth range being a range from a focal position in a depth direction of an imaging part to a position farthest from the imaging part in the depth direction out of ranges in the depth direction of a depth of field of the imaging part, and causes the imaging part to pick-up a region including the attention part.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2019,JPO&INPIT
