Abstract

Systems and methods include UAVs that serve to assist carrier personnel by reducing the physical demands of the transportation and delivery process. A UAV generally includes a UAV chassis including an upper portion, a plurality of propulsion members configured to provide lift to the UAV chassis, and a parcel carrier configured for being selectively coupled to and removed from the UAV chassis. UAV support mechanisms are utilized to load and unload parcel carriers to the UAV chassis, and the UAV lands on and takes off from the UAV support mechanism to deliver parcels to a serviceable point. The UAV includes computing entities that interface with different systems and computing entities to send and receive various types of information.

First claim

The invention claimed is:

1. An unmanned aerial vehicle (UAV) for delivering a parcel, the UAV comprising:
a UAV chassis comprising:
an upper portion including a plurality of propulsion members configured to provide lift to the UAV chassis;
a lower portion coupled to the upper portion, the lower portion defining an internal cavity;
one or more landing gear coupled to the UAV chassis between the upper portion and the lower portion; and

a parcel carrier configured to be selectively coupled to and decoupled from the UAV chassis independently of the one or more landing gear, the parcel carrier comprising:
an engagement housing configured to be at least partially inserted within the internal cavity of the lower portion of the UAV chassis and thereby secured to the UAV chassis; and

a parcel carrying mechanism coupled to and positioned below the engagement housing, wherein the parcel carrying mechanism is configured for engaging and holding the parcel.

2. The UAV of claim 1 , wherein the parcel carrying mechanism comprises a pair of parcel carrying arms, and wherein the one or more landing gear comprises a pair of rollers.

3. The UAV of claim 2 , wherein the parcel carrying arms are configured to move between an engaged position, in which the parcel carrying arms are configured to engage the parcel, and a disengaged position, in which the parcel carrying arms are configured to be spaced apart from the parcel.

4. The UAV of claim 3 , wherein the parcel carrier further comprises:
a motor configured for actuating the parcel carrying arms; and
a parcel carrier controller communicatively coupled to the motor, wherein the parcel carrier controller is configured to command the motor to move the parcel carrying arms between the engaged position and the disengaged position.

5. The UAV of claim 4 , wherein the parcel carrier further comprises a ground probe communicatively coupled to the parcel carrier controller, the ground probe configured to detect when a bottom surface of the parcel contacts a landing surface.

6. The UAV of claim 2 , wherein each one of the parcel carrying arms comprises an upper portion extending outward from the engagement housing and a lower portion extending downward from the upper portion.

7. The UAV of claim 6 , wherein each one of the parcel carrying arms further comprises a plurality of pins extending inward from the lower portion of the parcel carrying arms toward the parcel.

8. The UAV of claim 6 , wherein each one of the parcel carrying arms comprises a support flange extending inward from the lower portion of the parcel carrying arms, and wherein the support flange is configured to extend under a bottom surface of the parcel.

9. The UAV of claim 1 , wherein the lower portion of the UAV chassis includes a plurality of retaining members configured to engage the engagement housing of the parcel carrier and secure the parcel carrier within the internal cavity of the UAV chassis.

10. The UAV of claim 9 , wherein the plurality of retaining members are positioned about a perimeter of an opening into the internal cavity of the UAV chassis, and wherein the plurality of retaining members are adjustable between an extended position, in which the plurality of retaining members extend inward into the internal cavity and in which the plurality of retaining members are configured to secure the engagement housing of the parcel carrier to the UAV chassis, and a retracted position, in which the plurality of retaining members are withdrawn from the internal cavity and in which the plurality of retaining members are configured to allow removal of the engagement housing from the internal cavity.

11. The UAV of claim 1 , further comprising a ground landing sensor coupled to the UAV chassis, wherein the parcel carrying mechanism comprises a pair of parcel carrying arms, and wherein the ground landing sensor is positioned outside of a maximum parcel envelope defined by a maximum parcel size acceptable by the pair of parcel carrying arms.

12. The UAV of claim 1 , wherein the one or more landing gear comprises a pair of rollers coupled to a reduced width portion of the UAV chassis, and wherein a maximum width of the parcel carrying mechanism is greater than a maximum width of the one or more landing gear.

13. The UAV of claim 1 , further comprising a camera coupled to the lower portion of the UAV chassis.

14. An unmanned aerial vehicle (UAV) for delivering a parcel, the UAV comprising:
a UAV chassis comprising:
an upper portion including a plurality of propulsion members configured to provide lift to the UAV chassis;
a lower portion coupled to the upper portion, the lower portion comprising an internal cavity;
landing gear coupled to the UAV chassis between the upper portion and the lower portion; and

a parcel carrier configured to be selectively coupled to and decoupled from the UAV chassis independently of the landing gear, the parcel carrier comprising:
an engagement housing configured to be secured to the lower portion of the UAV chassis, wherein the engagement housing is configured to be at least partially inserted within the internal cavity of the lower portion of the UAV chassis to secure the engagement housing to the lower portion of the UAV chassis; and

a parcel carrying mechanism coupled to the engagement housing and positioned below the engagement housing and the landing gear, wherein the parcel carrying mechanism is configured to engage a parcel.

15. The UAV of claim 14 , wherein the parcel carrying mechanism comprises a pair of parcel carrying arms, and wherein the landing gear comprises a pair of rollers coupled to opposite sides of a reduced width portion of the UAV chassis located between the upper portion and the lower portion of the UAV chassis.

16. The UAV of claim 15 , wherein the parcel carrier further comprises:
a motor coupled to the pair of parcel carrying arms; and
a parcel carrier controller communicatively coupled to the motor, wherein the parcel carrier controller is configured to command the motor to move the pair of parcel carrying arms between an engaged position, in which the pair of parcel carrying arms are configured to engage the parcel, and a disengaged position, in which the pair of parcel carrying arms are configured to be spaced apart from the parcel.

17. The UAV of claim 15 , wherein each one of the parcel carrying arms comprises a first portion extending outward from the engagement housing in a first direction and a second portion extending from the first portion at an angle and in a second direction.

18. The UAV of claim 17 , wherein each one of the parcel carrying arms further comprises a plurality of pins extending inward from the second portion towards the parcel.

19. The UAV of claim 17 , wherein each one of the parcel carrying arms further comprises a support flange extending inward from the second portion, and wherein the support flange is positioned to extend under a bottom surface of the parcel.

20. The UAV of claim 14 , wherein the landing gear comprises a pair of rollers.
