Multi-zone automated storage and retrieval system

A multi-zone automated storage and retrieval system (ASRS) and a method for controlling operation of robotic storage/retrieval vehicles (RSRVs) therein are provided. The multi-zone ASRS includes first and second storage zones isolated by at least one barrier and including first and second groups of storage locations respectively for accommodating storage units therein. The multi-zone ASRS includes one or more portals opening through the barrier(s) between the storage zones, and at least one track layout. The track layout(s) includes first and second track areas occupying the first and second storage zones respectively, and one or more connective track segments interconnecting the first and second track areas through the portal(s). The RSRVs deposit and retrieve the storage units to and from the storage locations and travel on the first and second track areas via the connective track segment(s) to respectively access the first and second groups of storage locations therefrom.
