Abstract

In some embodiments, unmanned aerial task systems are provided that include a plurality of unmanned aerial vehicles (UAV) each comprising: a UAV control circuit; a motor; propulsion system; and a universal coupler configured to interchangeably couple with and decouple from one of multiple different tool systems each having different functions to be put into use while carried by a UAV, wherein a coupling system of the universal coupler is configured to secure a tool system with the UAV and enable a communication connection between a communication bus and the tool system, and wherein the multiple different tool systems comprise at least a package securing tool system configured to retain and enable transport of a package while being delivered, and a sensor tool system configured to sense a condition and communicate sensor data of the sensed condition to the UAV control circuit over the communication bus.

First claim

What is claimed is:

1. An unmanned aerial task system, comprising:
a plurality of unmanned aerial vehicles (UAV) each comprising:
a UAV control circuit;
a motor; and
propulsion system coupled with the motor and configured to enable the UAV to move; and
a universal coupler comprising a coupling system configured to interchangeably couple with and decouple from one of multiple different tool systems each having different functions to be put into use while carried by a first UAV and configured to secure one of multiple tool systems with the first UAV and enable a communication connection between the UAV control circuit and the one of the multiple tool systems, and wherein the multiple different tool systems comprise at least a package securing tool system configured to retain and enable transport of a package while being delivered.

2. The system of claim 1 , wherein the universal coupler of at least the first UAV of the multiple UAVs further comprises:
a first set of permanent magnets positioned to interact with a second set of permanent magnets of a first tool system, of the multiple tool systems to aid in alignment between the first tool system and the universal coupler; and
a set of at least one electromagnet positioned relative to at least a first permanent magnet of the first set of permanent magnets, wherein the UAV control circuit is configured to activate the set of at least one electromagnet to overcome a magnetic force relative to at a first permanent magnet and decouple the first tool system from the first UAV.

3. The system of claim 1 , wherein the universal coupler of at least the first UAV of the multiple UAVs further comprises at least a first alignment structure configured to engage and cooperate with at least a second alignment structure of a first tool system, of the multiple tool systems, as at least one of the first tool system and the first UAV is moved to enable coupling between the universal coupler and the first tool system.

4. The system of claim 3 , wherein the first alignment structure comprises a cavity, and the second alignment structure comprises a protrusion.

5. The system of claim 1 , wherein the universal coupler further comprises a gripping system that is configured to cooperate with a grip feature of a first tool system, of the multiple tool systems, and configured to secure the first tool system with the universal coupler.

6. The system of claim 5 , wherein the universal coupler of at least the first UAV of the multiple UAVs further comprises at least a first extension configured to engage a stop element formed in a mating surface of the first tool system aligning and inhibiting rotation of the first tool system while the gripping system is securing the universal coupler with the first tool system.

7. The system of claim 1 , further comprising:
multiple mounting stations each configured to support at least one of the multiple tool systems at least while being cooperated with a UAV, wherein the universal coupler of at least the first UAV further comprises at least a first alignment structure, and each of the multiple mounting stations comprises at least a second alignment structure configured to cooperate with at least the first alignment structure of the universal coupler as at least one of the first UAV and a first mounting station is moved to cause the cooperation between the first alignment structure and the second alignment structure to align a first tool system enabling secure coupling between the first UAV and the first tool system.

8. The system of claim 1 , wherein the universal coupler of the first UAV is further configured to temporarily couple with another universal coupler of a second UAV and maintain a position of the first UAV relative to the second UAV while the first UAV and second UAV are in motion.

9. The system of claim 1 , wherein the first UAV control circuit is configured to: cause the universal coupler to decouple from a first tool system of the multiple tool systems, control the movement of the first UAV to align the universal coupler with a second tool system configured to perform a second function that is different than a first function configured to be performed by the first tool system, control the movement of the first UAV to subsequently temporarily couple the universal couple with the second tool system, and control the movement of the first UAV and the second tool system to implement the second function provided through the second tool system.

10. The system of claim 9 , further comprising:
a mounting station configured to support at least one of the multiple tool systems at least while the at least one of the multiple tool systems is being cooperated with one of the plurality of UAVs, wherein the universal coupler further comprises a first alignment structure, and the mounting station comprises a second alignment structure configured to cooperate with the first alignment structure of the universal coupler as at least one of the first UAV and the mounting station is moved to cause a cooperation between the first alignment structure and the second alignment structure to align the universal coupler with the first tool system while the first tool system is supported by the mounting station, and enable secure coupling between the universal coupler and the first tool system.

11. A method of performing multiple different tasks through multiple unmanned aerial vehicles (UAV) each comprising a UAV control circuit and a universal coupler, comprising:
a UAV control circuit of a first UAV, of a plurality of UAVs, performing the following:
implementing an instruction to cause the first UAV to align with and temporarily couple with a first tool system of multiple different tool systems that are each configured to perform a different function of multiple different functions configured to be put into use while carried by one of the plurality of UAVs, wherein the first tool system comprises a package securing tool system configured to retain and enable transport of a package while being delivered;
controlling a propulsion system of the first UAV and aligning a universal coupler of the first UAV with the first tool system, wherein the universal coupler is configured to repeatedly and interchangeably couple and decouple between the multiple different tool systems to enable the first UAV to switch between the multiple different tool systems and enable implementation of the respective one of the different functions provided by the multiple different tool systems; and
causing a coupling system of the universal coupler to securely couple with the first tool system and enable a communication connection between the UAV control circuit and the first tool system.

12. The method of claim 11 , wherein the aligning the universal coupler with the first tool system comprises positioning the universal coupler such that a first set of permanent magnets of the first UAV are in a threshold distance of a second set of permanent magnets of the first tool system, wherein a magnetic interaction between the first set of permanent magnets and the second set of permanent magnets aid in alignment between the first tool system and the universal coupler; and
causing a decoupling the universal coupler from the first tool system comprising activating a set of at least one electromagnet positioned relative to a first permanent magnet of the first set of permanent magnets to overcome a magnetic force relative to at least the first permanent magnet.

13. The method of claim 11 , wherein the aligning of the universal coupler with the first tool system comprises engaging at least a first alignment structure of the universal coupler with at le
