Abstract
This simulation device comprises a simulation implementation unit that simulates a movement of a robot device, and estimates a movement path of a robot. The simulation device comprises a position information generation unit that generates three-dimensional position information for a surface of a workpiece on the basis of the output of a vision sensor, which has imaged an actual workpiece. A display unit displays the three-dimensional position information for the surface of the workpiece, superimposed on an image of a robot device model, an image of a workpiece model, and the movement path of the robot.
