The idea of the RoverLog warehouse system is to automate the storing of large-volume goods in a compact space and return to a specific location on request. (goods-to-man principle/Micro-Fulfillment) The goods are transported from the picking ports via a conveyor into the RoverLogs, and positioned there in the bin. The RoverLogs move below the goods in the support structure in X and Y to the desired destination cell. At the destination, the bin is lifted in and connected to the support structure. Our patented bins can, thanks to their quick lock system, build self-supporting stacks and thus enable a compact block storage. No extra shelf structure is required to stabilize the bin stacks. The goods can be delivered to any picking location. No additional sorter technology is required to distribute the goods.
