摘要： An aerial vehicle may have a fuselage, a first wing member, and a second wing member. The fuselage may have a nose end and a tail end. The first wing member may extend from the fuselage and comprise a first drive motor coupled to the first rotor. The second wing member may also extend from the fuselage substantially opposite the first wing member and may comprise a second drive motor coupled to a second rotor. A first motor may be coupled to rotate the first wing member and the first rotor about a first axis substantially perpendicular to a fuselage axis extending from the nose end to the tail end. A second motor may be coupled to rotate the second wing member and the second rotor about a second axis substantially perpendicular to the fuselage axis. A controller circuit may be configured to differentially actuate the first motor and the second motor.

摘要： An aerial vehicle that comprises a main frame and a plurality of operable multicopter units. Each multicopter unit has a plurality of propulsion units. The propulsion units are attached to the respective multicopter unit at a fixed roll angle, a fixed pitch angle and a fixed yaw angle. The plurality of operable multicopter units are attached to the main frame by interposition of respective joints and rotate relative to the main frame independently to each other. At least one of the joints has a minimum of one degree of freedom, such that the main frame has a at least the same or higher number of controllable degrees of freedom than the total number of degrees of freedom of the main frame.

摘要： A vertical take-off and landing aircraft which uses fixed rotors for both VTOL and forward flight operations. The wing rotors are tilted forward and provide some forward propulsion during horizontal flight. The rotors are positioned to achieve a high span efficiency. The rotors are positioned to even out the lift across the span of the synthetic wing. The synthetic wing may also have airfoils which may provide structural support for the rotors as well as providing lift during forward flight.

摘要： A compact harmonic drive system with a motor residing within the flexspline cup. The motor may reside further into the flexspline cup than the wave generator, and the air gap of the motor may be further out radially than the interior of the wave generator bearing. The motor may use an outrunner configuration with an outboard rotor made up of magnets, allowing for a large radial distance to the air gap and resulting in higher torque. The interior stator windings are thermally well coupled to the drive system structure. The harmonic drive may be coupled to a deployment system adapted to support moment loads perpendicular to the rotation axis such that those loads are not supported by the harmonic drive.

摘要： A hybrid foldable system of wings and rotors of a flying vehicle, and a flying vehicle. The flying vehicle includes a vehicle body, two wings, wing rotating mechanisms, rotor supports, rotor support rotating mechanisms, and rotor assemblies. The wings are movably connected to the vehicle body and the wing rotating mechanisms drive the wings to rotate to expand or retract. The rotor assemblies expand to two sides of each wing, or reversely rotate to retract to inner sides of each wing. Vertical taking-off and landing and stable flight in the air of the flying vehicle can be realized. In addition, when running on the ground, the wing and the rotor assemblies can be rotationally folded and placed on the inner sides of the vehicle body, so that space is reduced, and the limit requirements of urban roads regarding the size of the vehicle are satisfied.

摘要： A search and rescue drone system includes a buoyant body member, a frame attached to the buoyant body member for carrying a motor and propeller, and an electronic array including a camera, GPS, an EPIRB radio distress beacon, and a transmitter/receiver for remote control flying the drone and communicating with an operator. A laser guidance system may provide coordinates for landing near a swimmer in distress. The search and rescue drone may also be programmed to simply fly to the location of an electronic wearable device, like a bracelet, that is worn by a man overboard. In another embodiment, the search and rescue drone includes pivoting motor mounts, so that it can take off and land vertically with propellers rotating in a horizontal plane, and then the propellers may pivot to rotate in a vertical plane for propulsion across water similar to a fan boat with rescued people aboard.

摘要： A propulsion device for a rotating blade aerodyne with vertical take-off and landing, comprising a hollow chassis and contra-rotating coaxial rotors with fixed-pitch blades. The means for driving the rotation of each rotor comprise motor means and, for each rotor, a rotating part capable of turning about a yaw axis, located in the central opening of the respective rotor and connected to the latter via a ball joint with finger, the centre of which is the intersection of the prospective rotor disc and the yaw axis and for which the prohibited rotation is that about the axis of rotation of the rotor. Means for controlling the inclination of the rotors about the roll and pitch axes. Aerodyne equipped with the propulsion device.

摘要： Systems, methods, and other embodiments described herein relate to a drone having selectively actuated arms. In one embodiment, a drone includes arms connected to a body. Individual ones of the arms have a first end and a second end with the first end forming a connection with the body. The drone further includes rotor units individually including a propeller attached to a motor and mounted to the second end of the individual ones of the arms. Additionally, actuator units are integrated with the arms. Individual ones of the actuator units include electromagnetic cells that when activated induce an electromagnetic motive force that flexes the arms.

摘要： A flight controller of a drone calculates a target attitude of the drone on a port based on the result of acquisition by an anemometer. The flight controller of the drone controls each of a plurality of rotors independently, and controls each of the rotors so as to make the drone on the port take a target attitude.
