Secure high-precision delivery system and method

A method for secure delivery of items using a smart container system, the method comprising:

• transmitting, from a first ultra-wide band (UWB) device included in a first smart container disposed at a first property, a first UWB localization signal to a first delivery computing device;
• receiving, at an onboard computing device of the first smart container and from the first delivery computing device, a first request signal;
• verifying, at the first smart container, that the first request signal represents a valid request to access an interior chamber of the first smart container;
• opening, at the first smart container and in response to the verification, a first door to provide access to the interior chamber;
• verifying, using one or more cameras on the first delivery computing device, that the first door has completely opened;
• receiving, from a position directly above the interior chamber, a package;
• detecting, via one or more sensors included in a base of the first smart container, a presence of the package;
• and
• closing, in response to detecting the presence of the package, the first door, thereby resealing the first smart container;
• wherein the first smart container includes one or more heating and cooling elements, configured to keep the interior chamber of the first smart container within a predetermined temperature range;
• wherein the method further comprises detecting, via a leak sensor embedded in the base, a moisture content level that exceeds a preset threshold;
• and
• transmitting, from the onboard computing system, an alert to a mobile computing device associated with an owner of the first smart container.

A system for high-precision delivery of items using ultra-wide band (UWB), the system comprising a processor and machine-readable media including instructions which, when executed by the processor, cause the processor to:

• receive an order from a user for delivery of an item to a first property, the order including a selection by the user of a first micro-destination associated with a first UWB device on the first property out of a plurality of micro-destinations on the first property each associated with a different UWB device out of a plurality of UWB devices;
• cause, via an onboard computing system of an unmanned vehicle (UV), the UV to travel to an initial position near the first property, the initial position being in range of one or more of the plurality of UWB devices and in range of a first UWB localization signal generated from the first UWB device on the first property;
• determine, at the onboard computing system, a first position of the first UWB device relative to the UV based on the first UWB localization signal;
• and
• cause, via the onboard computing system, the UV to travel from the initial position to the first micro-destination associated with the first position of the first UWB device.
