A height error of a workpiece holding portion is detected based on a height from a mounting pedestal side floor surface, on which a mounting pedestal is mounted, to a connection point between the workpiece holding portion and an arm unit at a point in time at which contact with a detection target is detected by a surface detection sensor, a height from the mounting pedestal side floor surface to a surface of the detection target, and a theoretical value of a height of the workpiece holding portion, and an actual loading height of a workpiece mounted on the mounting pedestal is detected in consideration of the height error of the workpiece holding portion.

A pattern matching unit carries out a pattern matching between a photographed image obtained by photographing a workpiece with a monocular camera and a first plurality of models having a plurality of sizes and a plurality of angles, and selects a model having a size and an angle with the highest degree of matching. A primary detection unit detects a position and an angle of an uppermost workpiece based on the selected model. An actual load height calculation unit calculates an actual load height of the uppermost workpiece based on a hand height. A secondary detection unit re-detects the position and the angle of the uppermost workpiece based on a model having a size and an angle with the highest degree of matching selected by carrying out a pattern matching between the photographed image and a second plurality of models selected or newly created based on the actual load height.

Regarding predetermined positioning criteria (M, M), ((G, G), (N, or N), (K, K)), there is provided image processing means (B) for obtaining by image processing, measured values (C, C) ((G, G), (N, or N), (K, K)) and reference values (C, C) ((G, G), (N, or N), (K, K)), and for moving a work (W) in a manner that the measured values (C, C) ((G, G), (N, or N), (K, K)) and the reference values (C, C) ((G, G), (N, or N), (K, K)) coincide with each other, thereby positioning the work (W) at a predetermined position.
