Abstract

Described herein is an aerial material delivery system, which includes an unmanned aerial vehicle (UAV) including a body, and a material dispensing system mounted to the UAV, The delivery system also includes a collapsible storage container releasably mountable to the UAV. The storage container contains a flowable chemical product and includes at least one coupler adapted to couple the storage container to the material dispensing system of the UAV and allow the flowable chemical product to be dispensed therethrough.

First claim

What is claimed is:

1. An aerial fluid delivery system comprising:
an unmanned aerial vehicle (UAV) comprising a body;
a material dispensing system mounted to the UAV; and
a collapsible storage container releasably mountable to the UAV, characterized in:
the liquid storage container containing a pre-dosed amount of a chemical product and comprising at least one fluid coupler, the liquid storage container configured to receive a liquid via the at least one fluid coupler to form a liquid mixture with the chemical product, wherein the at least one fluid coupler is adapted to fluidly couple the liquid storage container to the liquid dispensing system of the UAV for dispensing the liquid mixture therethrough;
wherein the at least one fluid coupler comprises a single fluid coupler that functions as both an inlet for receiving liquid into the liquid storage container to mix with the chemical product and form the liquid mixture, and an outlet for supplying the liquid mixture to the liquid dispensing system.

2. The aerial fluid delivery system of claim 1 , wherein the liquid storage container includes a fill line indicator that corresponds to a liquid filling level of the liquid container needed to achieve a pre-determined concentration of the liquid mixture; and/or wherein the liquid storage container is constructed from at least one of a transparent material and a translucent material.

3. The aerial fluid delivery system of claim 2 , wherein the liquid storage container comprises a bag including at least sidewall constructed of a flexible film.

4. The aerial fluid delivery system of claim 3 , wherein the liquid storage container is constructed from at least one of plastic, polyethylene, modifier rubber, polyethylene terephthalate, nylon, Valéron, and film laminates; and/or
wherein the flexible film has a thickness from about 3 mil to 6.5 mil; and/or
wherein the flexible film has an areal density of less than 0.15 g/cm 2 .

5. The aerial fluid delivery system of claim 4 , wherein the liquid storage container comprises a unique identifier tag configured to wirelessly communicate with a controller of the UAV to identify at least one type of the chemical product contained within the liquid storage container and an amount of the chemical product contained within the liquid storage container.

6. The aerial fluid delivery system of claim 5 , further comprising a frame coupled to the UAV body, wherein the collapsible storage container is releasably mountable to the UAV by the frame.

7. The aerial chemical delivery system of claim 6 , wherein the frame is releasably coupled to the UAV body and/or wherein a bottom of the frame is coupled to a top of the UAV body; and/or wherein, when the liquid storage container is mounted to the UAV by the frame, a top of the liquid storage container is located above a top of the UAV body, and a bottom of the liquid storage container is located below the top of the UAV body.

8. The aerial fluid delivery system of any one of claims 1-7 , wherein the chemical product comprises at least one fertilizer, an insecticide, a fungicide, a nematocide, a bactericide, an araricide, a herbicide, a herbicide safener, a growth regulator, a chemosterilant, a semiochemicals, a repellent, an attractant, a pheromone, and a feeding stimulant; and/or wherein the chemical product comprises at least one invertebrate pest control agent.

9. A method characterized by comprising:
introducing a liquid into a collapsible storage container that contains a predosed amount of a chemical product to form a liquid mixture, the liquid storage container including at least one fluid coupler;
releasably mounting the liquid storage container to an unmanned aerial vehicle (UAV);
fluidly coupling the storage container to a liquid dispensing system mounted to the UAV using the at least one fluid coupler; and
dispensing the liquid mixture from the UAV using the liquid dispensing system; wherein the at least one fluid coupler comprises a single fluid coupler;
wherein introducing a liquid into the collapsible liquid storage container comprises introducing the liquid into the liquid storage container via the fluid coupler; and
wherein fluidly coupling the liquid storage container to a liquid dispensing system comprises fluidly coupling the liquid storage container to the liquid dispensing system via the same fluid coupler.

10. The method of claim 9 , wherein dispensing the liquid mixture from the UAV comprises:
operating the UAV such that the UAV flies over a field; and
dispensing the liquid mixture from the UAV while the UAV is flying over the field such that the liquid mixture is applied to the field.

11. The method of claim 9 , wherein releasably mounting the liquid storage container to a UAV comprises releasably mounting the storage container to the UAV using a frame coupled to a body of the UAV.

12. The method of claim 11 further comprising removably coupling the frame to the UAV body.

13. The method of claim 9 , wherein introducing a liquid into a collapsible liquid storage container includes filling the collapsible liquid storage container to a fill line indicator that corresponds to a liquid filling level of the liquid container needed to achieve a predetermined concentration of the liquid mixture.

14. A collapsible liquid storage container comprising:
a flexible sidewall constructed of an ultra-lightweight material, the sidewall at least partially defining a cavity;
a pre-dosed amount of a chemical product disposed within the cavity;
at least one mechanical coupler coupled to the sidewall and configured for releasable coupling to an unmanned aerial vehicle (UAV); and
at least one fluid coupler coupled in fluid communication with the cavity, wherein the liquid storage container is configured to receive a liquid into the cavity via the at least one fluid coupler to form a liquid mixture with the chemical product, and wherein the at least one fluid coupler is adapted to fluidly couple the cavity to a liquid dispensing system of the UAV such that the liquid mixture can be dispensed from the UAV liquid dispensing system.

15. The collapsible liquid storage container of claim 14 , wherein the at least one fluid coupler comprises a single fluid coupler that functions as both an inlet for receiving liquid into the liquid storage container to mix with the chemical product and form the liquid mixture, and an outlet for supplying the liquid mixture to the liquid dispensing system.

16. The collapsible liquid storage container of claim 14 , further comprising a fill line indicator that corresponds to a liquid filling level of the liquid container needed to achieve a pre-determined concentration of the liquid mixture.

17. The collapsible liquid storage container of claim 14 , wherein the at least one mechanical coupler is selected from the group consisting of grommets, hooks, buttons, snaps, clips, clamps, and bolts.

18. The collapsible liquid storage container of claim 14 , wherein the collapsible liquid storage container comprises a unique identifier tag configured to wirelessly communicate with a controller of the UAV to identify at least one of a type of the chemical product contained within the liquid storage container and an amount of the chemical product contained within the liquid storage container.

19. The collapsible liquid storage container of claim 14 , wherein the chemical product comprises at least one of a fertilizer, an insecticide, a fungicide, a nematocide, a bactericide, an acaricide, a herbicide, a herbicide safener, a growth regulator, a
