The RoverLog storage system was developed to automatically and efficiently store large-volume goods in a small space and to make them available again at the desired location (goods-to-man principle). It is integrated into the existing warehouse to save space. The system consists of various components that are connected to one another by a support / travel structure. The core of this are the RoverLogs, which move lengthways and crossways to bring the goods to the storage location and to form free-standing stacking columns there.
