Robot system

A robot system comprising:

• a robot for performing predetermined processing to a treating object;
• a photographing device for photographing the treating object;
• a robot control device for performing position compensation of a moving destination of the robot so as to track the treating object, the position compensation being performed based on (i) previously-set information on a position of the robot, (ii) previously-set information on a relative positional relationship between the robot and the photographing device, (iii) previously-set information on a position of the treating object, and (iv) an image of the treating object photographed by the photographing device;
• and
• a display device for providing an Augmented Reality (AR) space in which virtual information is superimposed and displayed on a real space;
• wherein the robot control device calculates a position of the treating object, based on the previously-set information on the position of the robot, the previously-set information on the relative positional relationship between the robot and photographing device, the previously-set information on the position of the treating object, and the image of the treating object photographed by the photographing device,
• the display device displays the image of the treating object photographed by the photographing device at a corresponding position in the AR space based on the calculated position of the treating object, and
• the AR space provided by the display device includes at least the treating object in the real space, and further includes the image of the treating object photographed by the photographing device as the virtual information.
