Claim One:
1. A teaching system comprising: a display unit; an image generating unit configured to generate a virtual image of a robot, a workpiece as a work target of the robot and a positioner for holding the workpiece; a display control unit configured to control the display unit to display the virtual image generated by the image generating unit; a work line generating unit configured to, upon receiving an operator's operation of selecting a ridgeline of the workpiece of the virtual image, extract individual teaching target points of the ridgeline and generate a work line as a set of line segments each interconnecting the target points adjoining each other; a calculation unit configured to calculate teaching values for positions and postures of the positioner on a point-by-point basis so that a vector direction of the work line at each of the target points becomes substantially parallel to a horizontal direction; and a teaching program generating unit configured to generate a teaching program for operating the positioner based on the teaching values calculated by the calculation unit.
