A robot system includes a robot including a robot arm and a first camera, a second camera installed separately from the robot, and a control device which controls the robot and the second camera. The first camera has already been calibrated in advance, and a first calibration data which is the calibration data between the coordinate system of the robot and the coordinate system of the first camera is known. The control device (i) images a calibration pattern with the first camera to acquire a first pattern image and images a calibration pattern with the second camera to acquire a second pattern image, and (ii) executes calibration process for obtaining a second calibration data which is the calibration data between the coordinate system of the robot and the coordinate system of the second camera using the first pattern image, the second pattern image, and the first calibration data.
