Abstract: Reduced workload on a user can be achieved when a sensing-related teaching program is to be generated. A method for generating a teaching program that defines sensing operation includes a setting step for setting a sensing position at a surface of a workpiece, and a generating step for generating a teaching program of the sensing operation based on the sensing position set in the setting step. The sensing position is set within a range in which a maximum permissible amount for an error of the workpiece and a permissible range preliminarily defined with respect to a direction of the error are included in the surface.

Abstract: A work measuring method for measuring a work including a columnar member and a diaphragm and held by a positioner includes an acquiring step of acquiring point cloud data on a surface of the work held by the positioner and photographed in a predetermined direction, a detecting step of identifying a portion where distribution of the point cloud data changes in a three-dimensional coordinate system of the positioner and detecting the portion as a boundary position between the columnar member and the diaphragm, and a deriving step of deriving the number of columnar members and diaphragms included in the work on the basis of the boundary position detected in the detecting step.
