Various embodiments include methods, devices, and aerial robotic vehicles for adjusting a proximity threshold implemented in a collision avoidance system based on whether propeller guards are installed. Methods may include an aerial robotic vehicle processor determining whether a propeller guard is installed, setting, a proximity threshold for collision avoidance based on the determination as to whether propeller guard(s) is/are installed on the aerial robotic vehicle, and controlling one or more motors of the aerial robotic vehicle using the proximity threshold for collision avoidance. When propeller guards are installed, the proximity threshold may be set at a smaller distance than when propeller guards are not installed. The determination of whether a propeller guard is installed may be based on sensor data from one or more sensors configured to detect or indicate the presence of a propeller guard, and/or based on rotor revolution rates determined from a motor or motor controller.

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.

A modular aerial vehicle for inspection of enclosed and open space environments. The aerial vehicle is employed for inspection of various environments in remotely controlled and autonomous fashions. The aerial vehicle is capable of carrying different sensory modules depending on the specific application including surface inspection. Aerial vehicle may be connected to a tether cable for electrical power delivery and transmission of control commands. The aerial vehicle may utilize a landing structure which allows landing on any angled metallic or non-metallic surface.

Example wirelessly powered unmanned aerial vehicles and tracks for providing wireless power are described herein. An example apparatus includes a track section having a transmitter coil to generate an alternating magnetic field and an unmanned aerial vehicle having a receiver coil. The alternating magnetic field induces an alternating current in the receiver coil when the unmanned aerial vehicle is disposed in the alternating magnetic field.

Described is an aerial vehicle, such as an unmanned aerial vehicle (UAV), that includes a plurality of sensors, such as stereo cameras, mounted along a perimeter frame of the aerial vehicle and arranged to generate a scene that surrounds the aerial vehicle. The sensors may be mounted in or on winglets of the perimeter frame. Each of the plurality of sensors has a field of view and the plurality of optical sensors are arranged and/or oriented such that their fields of view overlap with one another throughout a continuous space that surrounds the perimeter frame. The fields of view may also include a portion of the perimeter frame or space that is adjacent to the perimeter frame.

An unmanned aerial vehicle comprising a rotor having one or more propeller blades and a propeller guard surrounding the rotor. The propeller guard comprises a main guard surrounding the one or more propeller blades and a movable guard vertically displaced from the main guard. The movable guard is movable from a default position to an engaged position by temporarily deforming the movable guard such that the movable guard contacts and obstructs rotation of the one or more propeller blades.

A protective member of the present invention is configured as a protective member that is mountable to an aerial vehicle having a body 11 and at least one rotor held on the body, and includes a plurality of support members 22 that are connectable to the aerial vehicle and have a flexible member stretched between distal end portions thereof so as to surround an outside of the body in planar view, wherein at least one of the plurality of support members has a tension adjusting mechanism that is capable of adjusting a tension applied to the flexible member in a stretching direction, by changing a distance from a center of the body to the distal end portion.

A flying machine includes: a flying machine body that includes a rotor blade; a protective member that forms a frame shape inside which the rotor blade is disposed, that is rotatably fixed to both end portions of the flying machine body, and that is pipe shaped; and a connecting wire that passes through an inner portion of the protective member to connect the flying machine body and an external device together.

An aircraft has a propulsion unit and a fuselage unit. The propulsion unit has a first rotor for providing a propulsion force on the aircraft. The fuselage unit extends along a rotation axis of the first rotor and has a rotationally symmetrical shape with respect to the rotation axis of the first rotor. The fuselage unit has a suspension at a first end by which the fuselage unit is coupled to the first rotor so that the fuselage unit is spaced apart from the first rotor along the rotation axis. A detection unit for the detection of environmental information is provided in the area of a second end of the fuselage unit. The propulsion unit is designed to keep the aircraft in a hovering flight condition so that a relative position of the aircraft with respect to a reference point on the Earth's surface remains unchanged.

An assembly for an aerial system includes a wing support foldably connected to a first and second side of a body of the aerial system, a protection structure coupled to the wing support and disposed over propellers coupled to the wing support, wherein at least one of the protection structure and the wing support includes at least one of a positioning hook and a positioning groove, wherein the protection structure and wing support are fixed relative to each other with the at least one of the positioning hook and the positioning groove.
