Abstract: The simulation device include circuitry configured to: store a simulation model of a machine system including a robot, the simulation model generated to simulate a three-dimensional real shape of the machine system; receive measured data acquired by measuring the machine system in a real space; generate, based on the measured data, an actual shape model representing a three-dimensional real shape of the machine system; and correct the simulation model of the machine system based on a comparison between the simulation model and the actual shape model.

Abstract: A robot system includes: a conveying device configured to convey a workpiece; a robot configured to execute an operation on the workpiece; and circuitry configured to: identify a current position of the workpiece and an object area occupied by an object; identify an interlock area that moves with the current position of the workpiece being conveyed by the conveying device; check an overlap between the interlock area and the object area; and control the robot to execute the operation based on the current position of the workpiece in response to determining that the interlock area does not overlap the object area.
