Celluveyr was the university of blame de production and logistics institute (BIBA) in germany introduced an intelligent conveyor belt, and in our past knowledge, goods moved directionally along the conveyor belt to a fixed location within an express delivery facility. However, celluveyr has revolutionized a point where it is no longer a traditional conveyor belt, it is an intelligent transport and positioning system consisting of individual hexagonal modules, each containing three universal wheels, and each wheel being independently movable. By changing the linear combination of the speeds of the hubs, the center resultant speed and direction of the motion system can be controlled, and the goods can move on the conveying platform in 360 degrees in all directions. Utilize the computer program, can the rolling mode of arbitrary universal wheel on the independent control hexagon module, later through the different combinations between the hexagon module, realize complicated range to set for different goods letter sorting route, accomplish the goods letter sorting task in the data send process, and can also accomplish automatic pile up neatly through setting up the universal wheel after the goods conveys the terminal point.
