An unmanned vehicle including a body and a frame structure extending from the body and supporting a plurality of propeller assemblies, each propeller assembly including at least one propeller and a corresponding motor with the motor housed in a watertight housing or coated and made corrosion resistant. The propellers comprise a first subset of propellers of the propeller assemblies and a second subset of propellers of the propeller assemblies which rotate in a plane positioned below a plane in which the first subset of propellers rotate, wherein said first and second subset of propellers are configured for independent operation of one another as the vehicle transitions from an air medium to a water medium.

The invention relates to a drone, having at least one central body, at least one thrust element, at least one jointed leg, wherein the at least one jointed leg has leg parts which are connected via joints, wherein the at least one jointed leg is connected in an articulated manner via a proximal end to the central body. It is provided according to the invention that a distal end of at least one jointed leg has an exchangeable chuck, via which the distal end of the jointed leg can be connected to a selection of sensor devices and/or gripping devices and/or tools.

The present disclosure relates to a multirotor unmanned aerial vehicle, comprising a fuselage, being provided with at least one support arm in a transverse penetrating manner, and a rotor, being disposed at each end of the support arm in a transverse tilting manner. When the unmanned aerial vehicle moves transversely, the tilting rotors can provide lift force for keeping the unmanned aerial vehicle at certain altitude and also provide power for transverse movement of the unmanned aerial vehicle, and meanwhile, the fuselage does not need to tilt, so that the unmanned aerial vehicle has the advantages of high response rate and high flight speed.

An aircraft and its associated aircraft linear support arms. The aircraft linear support arms include at least a rotor motor and a propeller. The rotor motor is connected to the propeller, and the linear support arm has a cross-sectional shape of an inverted teardrop shape. The streamlined structure of the inverted teardrop-shaped arm can reduce eddy currents formed by the propeller's downwash flow due to interference caused by the aircraft body, thereby reducing the wear and tear of the lift motor and increasing the efficiency of the lift motor.

A remotely controlled flying device is intended to approach and contact a high-voltage overhead power line for operation thereon. The flying device includes a mechanical structure bearing propellers and an aircraft body containing at least a power hub, a flight controller, and radio communication means. An electrical shield encapsulates the mechanical structure. The remotely controlled flying device also has a surge protector or the like designed to locally capture and guide toward the electrical shield possible electric discharges in the phase of power line approaching and/or contacting and to render the electrical shield equipotential with the power line.
