The present invention relates to unmanned aerial vehicle for agricultural field assessment. It is described to fly (210) the unmanned aerial vehicle to a location in a field containing a crop. A body of the unmanned aerial vehicle is positioned (220) in a substantially stationary aspect above the crop at the location. A camera of the unmanned aerial vehicle is moved (230) vertically with respect to the body of the unmanned aerial vehicle between a first position and a second position, wherein the first position is closer to the body of the unmanned aerial vehicle than the second position. The camera acquires (240) at least one image relating to the crop when the camera is not in the first position.

A drone docking structure of an autonomous vehicle can include: a coil housing having a space for docking a drone to the vehicle; a docking cover configured to open or close a top portion of the coil housing according to whether the drone is docked; and a motor housing installed on a side surface of the coil housing and including a motor configured to actuate the docking cover.

An unmanned aerial vehicle (UAV) includes a central body and a plurality of landing gears that are extendable from and movable relative to the central body. The plurality of landing gears are configured to transform between a flight configuration and a surface configuration. In the flight configuration, the landing gears are extending laterally away from the central body and not in contact with a surface below the central body. In the surface configuration, the landing gears are extending towards the surface below the central body. When the landing gears are in the surface configuration, the landing gears are configured to support a weight of the central body on the surface and transport the UAV over the surface by moving one or more of the landing gears relative to the surface.

A drone docking structure of an autonomous vehicle can include: a coil housing having a space for docking a drone to the vehicle; a docking cover configured to open or close a top portion of the coil housing according to whether the drone is docked; and a motor housing installed on a side surface of the coil housing and including a motor configured to actuate the docking cover.

An apparatus in which electric power is generated for an electrical load from differentials in electric field strengths within a vicinity of powerlines includes: a plurality of electrodes separated and electrically insulated from one another for enabling differentials in voltage resulting from differentials in electric field strength experienced there at; and electrical components electrically connected therewith and configurable to establish one or more electric circuits whereby voltage differentials cause a current to flow through the established electric circuit for powering the electrical load. Preferably, the apparatus includes a control assembly having one or more voltage-detector components configured to detect relative voltages of the electrodes; and a processor enabled to configure—based on the detected voltages and based on voltage and electric current specifications for powering the electrical load—one or more of the electrical components to establish an electric circuit for powering the electrical load.

An interior length of a confined space is inspected by autonomously flying an unmanned aerial vehicle having a sensor pod. The sensor pod can be tethered to the unmanned aerial vehicle and lowered into the confined space from above perhaps by an electromechanical hoist. An altitude or heading of the sensor pod can be measured. The confined space can be the flue of a chimney.

An unmanned aerial vehicle (UAV) includes a central body, a plurality of arms extending out from the central body and in fluid communication with the central body, and a plurality of propulsion units. The plurality of arms are configured to route fluid away from the central body of the UAV. Each propulsion unit attached to a corresponding arm of the plurality of arms.

A parasite aircraft for airborne deployment and retrieve includes a wing; a fuselage rotatably mounted to the wing; a dock disposed on top of the fuselage and configured to receive a maneuverable capture device of a carrier aircraft; a pair of tail members extending from the fuselage; and a plurality of landing gear mounted to the wing. A method of preparing a parasite aircraft for flight includes unfolding an end portion of a wing; unfolding an end portion of a tail member of the parasite aircraft; and rotating a fuselage of the parasite aircraft so that the fuselage is perpendicular to the wing. A method of preparing a parasite aircraft for storage includes rotating a fuselage of the parasite aircraft to be parallel with a wing of the parasite aircraft; folding an end portion of the wing; and folding an end portion of a tail member of the parasite aircraft.

A system for deploying and retrieving a parasite aircraft includes a parasite aircraft with a dock and a carrier aircraft that includes a maneuverable capture device tethered to the carrier aircraft via a cable. The maneuverable capture device includes a plurality of rotors and is configured to dock in the dock of the parasite aircraft. A method of deploying a parasite aircraft includes positioning a parasite aircraft on a loading surface; positioning a carrier aircraft above the parasite aircraft; releasing, from the carrier aircraft, a maneuverable capture device comprising a plurality of rotors; securing the maneuverable capture device to a dock positioned on the parasite aircraft; lifting, via a cable secured at a first end to the carrier aircraft and at a second end to the maneuverable capture device, the parasite aircraft with the carrier aircraft; and releasing the parasite aircraft from the maneuverable capture device.

According to an embodiment of the present invention, an unmanned aerial vehicle (UAV) may recognize at least some of the light output from light sources of other unmanned aerial vehicles in swarm flight, and correct the location error based on the recognized light. An unmanned aerial vehicle (UAV) according to an embodiment of the present invention may be linked to an Artificial Intelligence module, a robot, a device related to a 5G service, and the like.
