    Abstract: A technique is directed to launching an unmanned aerial vehicle (UAV). The technique involves attaching a UAV launcher to a hand-held weapon, and installing a UAV onto the UAV launcher while the UAV launcher is attached to the hand-held weapon. The technique further involves activating the hand-held weapon to launch the UAV into flight from the UAV launcher. Since a user already may be carrying the hand-held weapon for firing ammunition, the user simply needs to further carry the UAV launcher and the UAV which, in some situations, can be packaged into an easy-to-carry container such as a backpack, a carrying case, and so on.

    Abstract: A control method for an unmanned aerial vehicle (UAV) is provided. The UAV includes an accelerometer, a gyroscope, at least one drive unit and at least one rotor. The method includes: detecting current motion data from the accelerometer, wherein the motion data includes displacement of the UAV; determining whether the UAV is thrown up based on the motion data; detecting current ascending velocity of the UAV; determining whether the current ascending velocity of the UAV is substantially equal to zero; detecting current pitch angle and current angular velocity from the gyroscope if the current ascending velocity of the UAV is substantially equal to zero; calculating drive data based on the current pitch angle and current angular velocity; and enabling the at least one drive unit to drive at least one rotor to rotate so as to cause the UAV to hover evenly.

    Abstract: A method and apparatus for launching unmanned air vehicles (UAVs) includes supporting the unmanned air vehicle on a surface vehicle, such as a dolly cart, for riding along a surface such as ground or water. A towline is connected to the surface vehicle and the towline is pulled to force the unmanned air vehicle in a forward direction at a speed sufficient for take-off. The towline may be pulled by a winch system. In some embodiments the UAV is positioned with a nose down angle on the surface vehicle. The nose down angle permits overspeed of the UAV and cart as it is pulled along the ground, as well as controlled take-off.
