Abstract:
Various embodiments include methods for piggybacking an unmanned aerial vehicle (UAV) on a vehicle (e.g., motor vehicles and trailers coupled to motor vehicles) to reach a destination. Various embodiments may include determining whether to dock on a vehicle. One or more candidate vehicles may be identified for docking. Travel profile characteristics of the one or more candidate vehicles may be identified. A first vehicle may be selected from the one or more candidate vehicles based on one or more travel profile characteristics that assist the UAV in reaching the UAV destination. The UAV may dock with the first vehicle. While docked to the first vehicle the UAV may charge an onboard battery via an electrical connection in a docking structure or by harvesting energy in the wind caused by movement of the vehicle by configuring the UAV rotors to charge the battery.
Abstract:
The drone comprises a body and a plurality of propulsion units, each provided with a propeller driven by a respective motor, the different motors being able to be controlled in a differentiated manner so as to pilot the drone in attitude and speed and with production of a lifting force. The accessory has a shaft that is removably fastened to the drone body in a transverse orientation with respect to the main direction of progression of the drone, and at a point located in alignment with the center of gravity of the drone and above that center of gravity. The accessory has two ring elements that are mounted freely in rotation, independently of each other, at the ends of the shaft and symmetrically with respect to the drone body. The density of these ring elements with respect to water is lower than the unit, and their diameter is higher than the overall size of the drone.

Abstract:
The present invention provides methods and apparatus for unmanned aerial vehicles (UAVs) with improved reliability. According to one aspect of the invention, interference experienced by onboard sensors from onboard electrical components is reduced. According to another aspect of the invention, user-configuration or assembly of electrical components is minimized to reduce user errors.
Abstract:
Described embodiments include an unmanned aerial vehicle and a method. The unmanned aerial vehicle includes an airframe and a rotary wing system coupled with the airframe and configured to aerodynamically lift the vehicle in the air. The unmanned aerial vehicle includes a flight controller configured to control a movement of the vehicle while airborne. The unmanned aerial vehicle includes a cleansing controller configured to manage a removal of a surface contaminant from a selected portion of a surface of an external object using an airflow generated by the rotary wing system.
