Abstract: The present disclosure provides a system and device for drones with ducted rotors. In some aspects, drones may comprise one or more systems of ducted rotors. In some embodiments, ducted rotors may increase the durability of the drone, limiting exposure of the rotors to external conditions and objects. In some aspects, a drone with ducted rotors may comprise a control vane or cone that may direct airflow within the drone as a mechanism to control flight path. In some implementations, a drone may comprise expandable landing gear than may allow for controlled landing, even in the event of rotor failure. In some aspects, a drone may comprise rotatable ducted rotors.

Abstract: The present disclosure provides for a rover used for painting and surveying. In some embodiments, a rover may comprise semi-autonomous small-scale vehicle with targeted capabilities to streamline processes that require precision or repetition. In some implementations, a rover may consistently and accurately traverse a space based on an instructed path and with a predefined purpose, such as painting, applying treatments, or seeding, as non-limiting examples. In some embodiments, the rover may paint lines in a defined space, like a parking lot or sports field. In some implementations, the rover may be deployable on a variety of surfaces, such as tile, mud, or grass. In some aspects, the rover may be configured to run according to Global Positioning System (GPS) coordinates or other coordinate system that may allow for automated patterns and paths. In some embodiments, the rover may run automated routes pre-programmed by a user.
