Beschreibung
Zusammenfassung:	A production system includes a machine tool (10), a robot (25) having a camera (31), an automatic guided vehicle (35) having the robot (25) mounted thereon, and a controller (40) controlling the automatic guided vehicle (35) and the robot (25), and has an identification figure arranged in a machining area of the machine tool (10). The controller (40) stores, as a reference image, an image of the identification figure captured by the camera (31) with the robot (25) in an image capturing pose in a teaching operation. When repeatedly operating the automatic guided vehicle (35) and the robot (25), the controller (40) estimates an amount of error between a pose of the robot (25) in the teaching operation and a current pose of the robot (25) based on the reference image and an image of the identification figure captured by the camera (31) with the robot (25) in the image capturing pose, and corrects operating poses of the robot (25) based on the estimated amount of error.
