Robot system

A robot system comprising a simulation device configured to place virtual models including at least a virtual robot model on a screen, display the virtual models simultaneously with a real equipment including at least a real robot, and perform teaching and simulation of a robot program,

• the simulation device comprising:
• a processor operable to:
• place the virtual models in a virtual space on the screen and display the virtual models simultaneously with the real equipment;
• perform teaching of the robot program in the virtual space;
• display the virtual models and teaching points of the robot program in a real space, based on a positional relationship in the virtual space;
• and
• correct placement positions of the virtual models to position the virtual robot model of the virtual models such that at least a part of the virtual robot model having a shape overlaps with a corresponding same part of the real robot having the same shape, and that peripheries of the part of the virtual robot model and peripheries of the corresponding same part of the real robot overlap and are aligned with each other in the real space.
