In this study , the pouring control system which the flow rate controlis installed as the core control system has been developed for pouring precisely and quicklythe molten metal into the mold for a tilting-ladle-type automatic pouring robot used incasting industry . In this approach, the flow rate estimation system has been designed byKalman filter , and the flow rate feedback control system using the estimated flow rate has been constructed. Furthermore, high-precision outflow weight control system has beenrealized by integrating systematically the outflow weight control with the flow rate controlas the core control system. In order to pour precisely to the target position, the fallingposition control system has been developed.
