LC1-015D12 Bi-directional roller conveyor AGV based on the SLAM algorithm, the map and path definition are stored in the AGV vehicle controller, which can realize autonomous navigation according to the on-site environment without reflective columns/boards for reference. It can communicate with the host computer system through the wireless ModbusTCP protocol, accept scheduling instructions and feedback its own status. It can realize simple traffic control and fixed line calling task functions without the wireless local area network and feedback its own status,this AGV handles goods in the form of direct roller conveying, which is often used for the handling of heavy load and large volume goods.
