There is provided an aerial platform comprising a spraying module, one or more actuators operatively coupled to the spraying module, at least a sensor for acquiring data indicative of altitude, wherein at least a controller is configured to control a position of the spraying module relatively to the aerial platform based on control signals generated during control cycles and applicable to the one or more actuators, the controlling comprising cyclically acquiring with said sensor data indicative of an altitude of a surface area in the flight path direction of the aerial platform, wherein said surface area is to be sprayed in a next control cycle, generating a control signal based on at least said acquired data, so as to maintain the altitude of the spraying module at a required distance of the altitude of the surface, and applying the generated control signal to the one or more actuators. There is also provided methods and systems for controlling a motion of the spraying module.

To provide a flying object including a lift generating member deployment device that makes it easier than before to automatically avoid collision with an obstacle. A flying object 30 includes an obstacle detecting unit 5, a control unit 6, a battery 7, a storage unit 8 that stores information transmitted from the control unit 6, a transmitting/receiving unit 9 that receives an operation signal from a controller 40 and transmits information regarding the flying object 30 to the controller 40, and others. The obstacle detecting unit 5 is to detect the altitude of the flying object 30 and outputs an altitude detection signal, which represents the detected altitude information, to the control unit 6. In addition, upon detecting an obstacle present within a predetermined distance, the obstacle detecting unit 5 outputs an obstacle detection signal to the control unit 6, detects the distance between the flying object body 31 and the obstacle, and outputs a distance detection signal, which represents the detected distance information, to the control unit 6. The control unit 6 determines whether or not to actuate left and right brake cord pulling devices 10 in accordance with the signal received from the obstacle detecting unit 5.

An aircraft includes: a plurality of rotor units each including a propeller and a motor that drives the propeller; and a shock absorber covering the entire vertical length of lateral sides of the plurality of rotor units.

This application describes systems, methods, and devices to enhance the safety and functionality of unmanned rotorcraft by improving reliability, transparency, operational capabilities, and effectiveness. Embodiments include integration of rotorcraft with objects attached to the ground (including kites, balloons, or elevated structures) in order to create safe and visible sky moorings from which devices such as cameras on the craft can operate for extended periods of time while remote control can be used to move and stabilize the camera and/or the kite or balloon to which it is attached. In addition, the rotorcraft in such sky moorings can be enclosed for protection, can employ connections for systems maintenance, and can utilize changeable payload modules having supplies that the rotorcraft can dispatch or use in various contexts such as emergency situations or to provide security at venues with large gatherings of people, such as concerts.

A method of using a bagged power generation system comprising windbags and waterbags integrated with drones and adapting drone technologies for harnessing wind and water power to produce electricity. An extremely scalable and environmentally friendly method, system, apparatus, equipment, techniques and ecosystem configured to produce renewable green energy with high productivity and efficiency.

In an embodiment, a ducted fan propulsion system comprises an outer cowling, adapted to form a duct. The duct houses one or more fan blades rotating about a central axis. One or more motors are in communication with the fan blades and in communication with a power source. The duct is transversed by a plurality of spokes. In an embodiment, multiple ducts are housed within an outer cowling, with each duct comprising one or more rotatable fan blades, one or more central axes, and one or more motors. In each embodiment, one or more members are attached to the ducted or multi-ducted fan propulsion system and extend to a user or vehicle. The members terminate in a handle further comprising a throttle adjuster.

The present invention provides a method for decelerating and redirecting an airborne platform, comprising the steps of retaining a flexible airfoil in non-deployed form in controllably releasable secured relation with each corresponding rotor arm of a multi-rotor drone; and upon detecting rate of descent of said drone in a first direction to be greater than a predetermined value, triggering release of one or more of said retained airfoils from said corresponding rotor arm and causing each of said released airfoils to be circumferentially displaced from a first rotor arm to a second rotor arm of said drone to occlude an adjacent inter-arm region, wherein each of said circumferentially displaced airfoils generates a sufficient value of localized lift that causes said descending drone to change its direction of descent from said first direction to a second direction.

A drone according to an embodiment may comprise: a support table; a main unit spaced from the support table and formed above the support table; a connecting portion for connecting the main unit and the support table; and a propulsion unit provided on the outer side of the support table so as to generate thrust. The main unit may have a through-hole formed therein, a parachute may be provided inside the through-hole, and, during a fall, the parachute may be discharged out of the through-hole by deformation of the connecting portion.
