The replacing yarn system of the intelligent creel Multirobot is integrated in unity of winding, transporting, transiting and supplying robots. The distributed control system of Multirobot for intelligent creel based on CAN bus was designed that adopted the idea of centralized management and distributed control. Interactive interface and the operating were achieved by using LabVIEW software. The path planning of the supplying robot which was the core part in the system based on the standard of the shortest distance was proposed aimed at the time of replacing yarn may be ever shorter. Automatic replacing yarn in the Axminster carpet loom can be done, which saved the labor and time costs, and improved the efficiency of weaving carpets also.
