Abstract
To provide a robot vision system capable of making calibration at the time of starting a robot unnecessary and re-calibration during an operation unnecessary.SOLUTION: A robot vision system 102 comprises: an operation control unit 164 that controls an operation of an arm 124 of a robot 100; an end effector 126 attached to the arm; cameras 130 and 132 attached to the arm to capture images 168 and 170 near the end effector; and a correction unit 162 that calculates a gain. During a visual feedback operation of the robot using the cameras, the cameras capture the images, the correction unit calculates a moving amount of the arm on the images using a design value containing the attaching positions and the attaching angles of the cameras with respect to the end effector, and calculates a gain on the basis of a ratio of the moving amount of the arm on the images to the moving amount of the arm under the numerical control of the robot, and the operation control unit operates the arm using the gain calculated by the correction unit.SELECTED DRAWING: Figure 4
