The delivery vehicle is further adapted to transport the storage container between the delivery port and a second location for handling of the storage container by at least one of a robotic operator and a human operator.

The disclosed technology relates to a method and system for localizing and confining an autonomous mobile work system or systems for performing work in a user defined space is disclosed. The system can include two or more variable reflective base stations at first and second locations that can modify their optical or electromagnetic reflectivity based upon either an external command via wired or wireless communications interface, or automatically on a regular or asynchronous time schedule under programmed or user settable control. The system also can include one or more autonomous mobile work systems capable of sensing the state of the variable reflectance base stations via sensors such as electromagnetic or optical sensors capable of measuring distance to the reflective base stations.

A vehicle tilting device for tilting a delivery vehicle for increasing access to items from a storage container transported on the delivery vehicle. The vehicle tilting device comprises a base structure and a tiltable platform connected to the base structure, wherein the tiltable platform comprises guiding features adapted to guide the delivery vehicle onto the tiltable platform. The tiltable platform is arranged to be connected to a delivery grid cell of a delivery rail system such that that there is a path to and/or from the tiltable platform for the delivery vehicle via the delivery grid cell. The invention is also related to an access station, a delivery system and a method of accessing a storage container.
