A flying sensor comprising an unmanned aerial vehicle (UAV) and at least one profiler mounted on the UAV, the profiler comprising a base, a scanning unit for providing (LiDAR) data, the scanning unit mounted on the base and comprising a shaft carrying a deflector and being mounted in the scanning unit and rotatable, a transmitter transmitting a transmission beam, a first receiver configured for receiving a first reception beam reflected from the setting via the deflector, and an electric port configured for connecting the profiler to the UAV, and comprising a data interface and a power interface, and wherein the UAV comprises a visual sensor providing visual data, and comprising one or more cameras, a pose sensor for providing pose data, and a computer to compute a 3D point cloud based on the LiDar data and a Simultaneous Localisation and Mapping (SLAM) algorithm using the visual and pose data.

A motorized device capable of moving in a fluid and including one or more locomotor systems, each having at least one drive assembly linked to at least one locomotion member and a motor controlled by a voltage. The frequency of a reciprocating motion of the drive assembly matches the resonant frequency of the locomotion member linked to a non-movable portion by at least one prestrained elastic member. The instantaneous amplitude of the reciprocating motion of the drive assembly is adjusted to control the average position and the maximum amplitude of the reciprocating motion of the locomotion member. The drive assembly includes at least one speed reducer for reducing the speed of rotation of the motor. When the motor is operating at its maximum mechanical power, the speed of rotation transmitted to the at least one locomotion member is reduced to match the resonance frequency.

A multi-rotor flying machine includes a body on or in which a motor is mounted; and a respective head rotor mounted for rotation on a respective mast at each of at least three locations disposed around and spaced laterally outwardly from the motor. The motor is drivingly connected to each mast, for rotating each head rotor, by a respective driveline. Adjacent to at least one mast, the machine further includes a pitch rudder system that includes a pitch driver or rotor, or translational rotor. The arrangement is such that the head rotors are operable to provide thrust, while the pitch rudder system enables yaw to be achieved independently of operation of the head rotors.

According to one embodiment, a flying body includes a radar, a supporter, a plurality of rotors supported by the supporter, and a controller. The rotors include a first rotor. The radar is configured to perform a detection operation and a non-detection operation. The controller is configured to perform a first control operation in a first transition from the non-detection operation to the detection operation. The controller is configured to perform a first change in the first control operation to change a rotational speed of the first rotor from a rotational speed of the first rotor in the non-detection operation. The detection operation is performed after the first control operation.

An unmanned aerial vehicle (UAV) has a flight-only mode with a motor only rotating propellers and not rotating on-board wheels to configure the UAV to fly away from a surface of a structure, and a crawling-only mode in which the UAV is configured to crawl on the surface due to the motor only rotating the wheels while not rotating the propellers. In the flight-only mode, a clutch disengages a motor from the wheels so that the motor only engages the propellers to fly to lift from the surface. In the crawling-only mode, the clutch disengages the motor from the propellers so that the motor only engages the wheels to move the UAV on the surface.

A collapsible flying device is provided having a housing including first and second housing sections forming an enclosure, and a motorized assembly that includes a drive motor and a drive shaft driven by the drive motor. The drive shaft matingly receives the first housing section and is coupled to the second housing section, wherein operation of the drive motor drives the drive shaft to move the first housing section from a closed position adjacent the second housing section to an open position spaced from the second housing section. A rotor hub is rotatingly driven by the drive motor. At least two rotor blades are coupled thereto and positioned within the enclosure in a collapsed position when the first housing section is in the closed position, and extend beyond the enclosure in an expanded position when the first housing section is in the open position.

An unmanned aircraft includes three parallel beams extending in at least one longitudinal direction X from a rear side to a front side of the aircraft, the central beam forming a main fuselage containing a powertrain, with a propeller of diameter D configured to be driven by the powertrain being attached to a front end of the central beam, each side beam being at a distance L/2 from the central beam and each side beam supporting a radar at a front end of the beam.
