Several motorized terrestrial transport units 701 are loaded into a mother vehicle 702 along with several items 703 to be delivered to various different recipients. The mother vehicle moves to a delivery location and a motorized transport unit is dispatched to deliver one or more items to a recipient. Before that transport unit returns to the mother vehicle for recovery, the mother vehicle moves to a second delivery location and dispatches a second motorized transport unit to deliver one or more different items to a second recipient. The mother vehicle subsequently recovers at least the first transport units at a recovery location. The items may be pre-loaded into lockers 132 that may be pre-attached to corresponding transport units. The lockers may be secured so that they can be opened only using an unlocking mechanism 704. The transport units may be guided to their respective recovery locations. |
