Abstract

Some embodiments of the invention provide methods and apparatus enabling multiple unmanned cargo deliveries in a single mission. An assembly having multiple hooks may be coupled to an unmanned vehicle via a cable. Prior to a mission originating at a starting location, multiple cargo loads may each be loaded on to a respective pallet, wrapped in a cargo delivery net, and attached to one of the hooks. A ground controller may instruct the unmanned vehicle to deliver the cargo loads to separate locations. The unmanned delivery vehicle may navigate to a first delivery location, perform delivery of a first cargo load by causing the hook on the assembly to release the first load, autonomously exit the first location and navigate to a second delivery location without returning to the starting location, and perform delivery of a second cargo load by causing the hook on the assembly to release the second load.
