Reporters obtained the following quote from the background information supplied by the inventors: “Generally, warehouses for the storage and retrieval of produc ts or items comprises a series of racks that are accessible by transport devices comprising a lifting device such as forklifts that are moveable within aisles b etween the racks. The products or items are typically stored on pallets or other storage containers and placed on different levels of the racks. A transport dev ice, either manually driven or automated, travels up and down aisles between the racks and the lifting device is used to retrieve a pallet storing a particular product or item thereon from the racks. However, the storage and retrieval of pr oducts is very labour intensive and time consuming. With the rapid growth of e-c ommerce, there has been a drive to provide a more automated storage and retrieva l system to cater for the increasing demand of online purchases.
