Abstract

Unmanned aerial vehicle (UAV) capture devices and methods of operation are disclosed. A UAV capture device may include a netting system including a net launch device and a net, a propulsion system including a plurality of propellers coupled to one or more motors, a positioning system, a camera system, and a processing system coupled to the netting system, the propulsion system, the positioning system, and the camera system. The processing system may include logic to operate the propulsion system to autonomously navigate to a general location of a target UAV, to operate the propulsion system to pursue the target UAV, to deploy the netting system to propel the net at the target UAV, and to confirm if the target UAV is captured in the net. Other aspects, embodiments, and features are also included.

First claim

What is claimed is:

1. An unmanned aerial vehicle (UAV) capture device, comprising:
a netting system including a net launch device and a net;
a propulsion system including a plurality of propellers coupled to one or more motors;
a positioning system;
a camera system; and
a processing system coupled to the netting system, the propulsion system, the positioning system, and the camera system, the processing system comprising logic to:
operate the propulsion system to autonomously navigate to a general location of a target UAV in response to information obtained from the positioning system and from the camera system;
determine a size and shape of the target UAV utilizing information obtained from the camera system;
identify the target UAV as a target to be captured based on the determined size and shape;
determine a direction of travel of the target UAV and a speed of the target UAV from images and information obtained by the camera system;
operate the propulsion system to pursue the target UAV in response to the determined direction of travel of the target UAV and a speed of the target UAV; and
deploy the netting system to propel the net at the target UAV.

2. The UAV capture device of claim 1 , wherein the netting system further includes:
a tether coupled between the net and the UAV capture device;
a net disconnect; and
a capture detector.

3. The UAV capture device of claim 2 , wherein the processing system further comprises logic to detect whether the netting system successfully captured the target UAV utilizing information obtained from the capture detector.

4. The UAV capture device of claim 3 , wherein the capture detector comprises a load cell, and wherein the logic to detect whether the netting system successfully captured the target UAV comprises logic to determine whether the netting system successfully captured the target UAV utilizing information obtained from the load cell.

5. The UAV capture device of claim 2 , wherein the processing system further comprises logic to initiate the net disconnect to untether the net from the UAV capture device.
