Abstract: Described herein are autonomous delivery devices for loading, transporting, and unloading cargo. In some embodiments, a delivery device includes: a first modular cargo defining a container interior for enclosing cargo therein; and a transportation platform having a plurality of wheels for transporting the first modular cargo container from an origin to a first destination. In some embodiments, a second modular cargo container may be positioned on an upper surface of the first modular cargo container for delivering a second cargo to a same of different destination. In some embodiments, the transportation microcomputer is configured to receive delivery instructions and activate the transportation platform to autonomously move towards a destination. Upon arriving at a destination, the transportation microcomputer transmits an open position electrical signal to position the rear door of the first or second cargo container in the open position, such that a cargo is unloaded at the destination.

Abstract: Described herein are cargo handling systems for loading, transporting, and unloading cargo from autonomously delivery devices. In some embodiments, the cargo handling system includes: a system processing unit for controlling operations of the cargo handling system; and one or more modular racks. Each rack includes a rack processing unit, a frame, and one or more moveable arm sets. Further, each rack is configured to store, dock, and undock one or more modular cargo containers according to received signals from the system processing unit. In some embodiments, the system processing unit transmits one of: a docking signal and an undocking signal to dock or undock, respectively, the identified modular cargo container. In some embodiments, the system further includes a shuttle for transporting, at least in part, a modular cargo container in the modular racks.
