AS/RS Systems, Automated storage and retrieval systems, are computer controlled systems for storing and retrieving products in a warehouse or distribution centre. AS/RS Systems require virtually no manual labour and are engineered to be completely automated.
Another AS/RS technology is known as shuttle technology. In this technology the horizontal movement is made by independent shuttles each operating on one level of the rack while a lift at a fixed position within the rack is responsible for the vertical movement. By using two separate machines for these two axes the shuttle technology is able to provide higher throughput rates than mini-loads (stacker cranes).
Storage and Retrieval Machines pick up or drop off loads to the rest of the supporting transportation system at specific stations, where inbound and outbound loads are precisely positioned for proper handling.
