A computer-implemented method for controlling an unmanned aerial vehicle (UAV) includes identifying a set of target markers based on a plurality of images captured by an imaging device carried by the UAV. The set of target markers includes at least two or more types of target markers that are in close proximity to be detected within a same field of view of the imaging device. The method further includes determining a spatial relationship between the UAV and the set of target markers based at least in part on the plurality of images, and controlling the UAV to approach the set of target markers based at least in part on the spatial relationship while controlling the imaging device to track the set of target markers such that the set of target markers remains within the same field of view of the imaging device.

A landing pad receives and stores packages delivered from an aerial vehicle and awaiting pickup from an aerial vehicle. The landing pad can be placed outside of a window and can contain a transmitter for sending out an identification signal via radio frequency to aid aerial vehicles in finding the landing pad. The landing pad contains a landing platform with a trapdoor that leads to a storage compartment. The trapdoor can be configured to only open when it receives a signal from an authorized aerial vehicle. The storage compartment can be accessed via a storage compartment door which can contain a locking mechanism. The storage compartment can be climate controlled. The landing pad can also have a transmitter that emits sounds to discourage animals from nesting on or near the landing pad. The landing pad can also include a solar power generator as a source of electrical energy.

An aerial vehicle includes a body and a wireless charging receiver pad connected to the body, whereby the aerial vehicle is configured to be wirelessly charged when parked above a wireless charging transmitter pad. The aerial vehicle includes landing gear connected to the body and extending underneath the body. The landing gear is configured for actuation to control the location of the receiver pad with respect to the transmitter pad.

A vertiport for an aircraft. The vertiport includes a landing platform that includes a landing surface and a plurality of primary through-openings, wherein the landing platform at least partially defines a primary chamber subjacent to the landing platform, the primary chambering having a primary chamber volume, and wherein the plurality of primary through-openings are in fluid communication with the primary chamber. The disclosed vertiport further includes an air moving unit positioned to withdraw air from the primary chamber.

A multi-level structure conveying system and method for assisting UAV landing are provided. The system includes conveying units and modular bottom plates. The modular bottom plate provides line connection between a power supply and a controller for the conveying unit. The conveying unit drives a UAV to move through driving a conveyor to move. Placement of the conveying units in different directions is used to control a movement direction of the UAV. The conveying units are connected through side plate modules to be arranged into conveying modules with different trajectories. The UAV moves on the conveying modules under driving of each conveying unit to reach a target position. A side plate bump of each conveying unit is sleeved opposite to a side plate recess of the adjacent conveying unit. A hollow channel formed by side plate holes of the adjacent conveying units is fixed by adopting a connecting shaft.

An unmanned aerial vehicle airport, an unmanned aerial vehicle system, a tour inspection system and an unmanned aerial vehicle cruise system. The unmanned aerial vehicle airport comprises a support base, a parking apron, a protective cover and a protective cover opening and closing driving device. The parking apron is installed on the top of the support base; the protective cover covers the top of the apron; the protective cover opening and closing driving device is installed between the support base and the protective cover, and the protective cover opening and closing driving device is configured to cause a bar linkage mechanism to drive the protective cover to switch between an open position and a closed position. The unmanned aerial vehicle airport is provided with the protective cover for the parking apron. If the protective cover is open, the unmanned aerial vehicle is parked on the parking apron, and takes off from the parking apron.

A robust amphibious air vehicle incorporates a fuselage with buoyant stabilizers and wings extending from the fuselage. At least one lift fan is mounted in the fuselage. Movable propulsion units carried by the wings are rotatable through a range of angles adapted for vertical and horizontal flight operations.

A system for landing an unmanned aerial vehicle has an unmanned aerial vehicle and a ground-based platform. A guide structure for receiving the unmanned aerial vehicle is mounted on the ground base platform. The guide structure has an inner diameter greater than a smallest outer diameter of the unmanned aerial vehicle landing gear and less than the largest outer diameter of the unmanned aerial vehicle landing gear.

An external power assist system for an eVTOL aircraft having one or more onboard batteries includes a subsurface power source and a power transfer interface electrically coupled to the subsurface power source. The power transfer interface is movable between various positions including a deployed position and a stowed position. The power transfer interface is configured to transfer power to the onboard batteries of the eVTOL aircraft in the deployed position. The power transfer interface is moved at least partially subsurface in the stowed position.

Method and system to ascertain location of drone box for landing and charging drones comprising at least a drone box having a drone platform with a plurality of limiting boundaries, divided into number of sensor zones that are mechanically contiguous and electrically separated by an insulated separator of insulation width, each sensor zone having an identification coordinates, each drone having a plurality of ground interfaces, each having a unique address code, each ground interface has a charging terminal at a far end, each charging terminal having an interlocked switchable electricity polarity. The identification coordinates of the activated sensor zones are communicable to a second drone so that the second drone knows where NOT to land on the drone box, Such communication enables a third and subsequent drone to ascertain whether the identified drone box is suitable and available for landing.
