Abstract: There is provided a method of controlling laser scanning by a rotorcraft. The rotorcraft includes: a rotatable body frame configured to rotate during flight; a laser rangefinder mounted on the rotatable body frame and configured to perform laser scanning; and a magnetometer configured to measure magnetic field. The method includes: obtaining magnetic field measurement data from the magnetometer while the rotatable body frame is rotating during flight, the magnetic field measurement data including a sinusoidal signal; estimating a frequency of the sinusoidal signal; and controlling the laser rangefinder to perform laser scanning based on the estimated frequency of the sinusoidal signal. There is also provided a corresponding controller for controlling laser scanning by a rotorcraft, and a corresponding rotorcraft configured to perform laser scanning including the controller.

Abstract: According to various embodiments, there is provided an aerial vehicle. The aerial vehicle includes: an airframe comprising a central member defining a longitudinal axis; a gimbal coupled to the central member; a camera mounted on the gimbal to face a direction at least substantially orthogonal to the longitudinal axis; wherein the gimbal is rotatable about the longitudinal axis to spin the camera around the longitudinal axis; and a propulsion means configured to propel the aerial vehicle, wherein the propulsion means is offset from the camera along the longitudinal axis.

Abstract: An aircraft including: a pair of wings rotatably coupled to opposing lateral sides of the fuselage and being rotatable relative to each other; a pair of servo motors, each connected to a corresponding wing and configured to rotate the corresponding wing in two rotational directions; a pair of thrust motors, each of which mounted on a corresponding wing; and a flight controller connected to the servo motors and to the thrust motors, and configured to control each servo motor and each thrust motor, such that the aircraft can be selectively operated in a cruising mode, such that the pair of wings are in a non-permanent-rotation-state about a yawing axis which extends at least substantially through the center of gravity, and a monocopter mode, in which the pair of thrust motors provide thrust in opposite directions so that the pair of wings are in a permanent-rotation-state about the yawing axis.
