The unmanned aerial device also includes an image capturing device configured to capture one or more images and to capture one or more attributes associated with the corresponding at least one of the one or more users and the one or more objects, a thermal image capturing device configured to detect occupancy of the smoke and fire by an infrared sensor within the pre-defined area and to generate one or more thermal images.

An improved drone with 4 flat wings reciprocating up and down, complete with motor and electronics. Appendages on each wing's surface allow air to pass across it during the up-motion, and block it in the down-motion; this creates lift and permits flight and manoeuvres. The drone resembles either a flying bird or an insect, depending on wing motion and on passive attachments appropriate for the respective resemblance, making for inconspicuousness. The drone can execute complex work, either as solitary or in a team, either in flight or at rest in various places, after approaching and adhering expertly.

A system (100) for determination of flight performance of the bioinspired flapping-wing aerial vehicle (101) in simulated space conditions discloses the aerial vehicle (101) installed in a thermo-vacuum chamber (103) that maintains vacuum and temperature for aerial vehicle (101) to simulate climatic conditions in space, where the aerial vehicle (101) is evaluated by the force transducer (104) and data acquisition system (105) acquires the data from force transducer (104). The flapping motion of the wing (101b) of the aerial vehicle (101) in space conditions increases the velocity of aerial vehicle (101), where dynamic wing twisting maintains the wing (101b) at a specific angle of attack to generate lift force and wing deformation occurs during which the passive pitch angle produces high lift forces, facilitating stable flight in simulated space conditions.

Aerial vehicles, their structures and methods of locomotion are described. An aerial vehicle may include a fuselage having an x-axis, a plurality of flexible structures emanating from the fuselage that take the form of a feather, wing and/or tentacle, at least one motor, and at least one propeller driven by one or more motors. Each flexible structure may extend from a fuselage in any direction and are used to enhance the observability of the aircraft by moving and/or oscillating within a frequency band and at a magnitude that is more easily observed by and catches the human eye.

This invention relates to a drone, method and systems for displaying messages and/or images by using a group of one or more remotely controlled airborne drones provided with display means and controlled so the messages and/or images are created and are visual by the display means of the group of airborne drones. The display means are controlled such that the messages and/or images are 2D or 3D respectively. The display means may include LED's, OLED's or LCD based on means or DLP and/or laser projection means. The display of messages and/or images can be remotely controlled using a social gateway for airborne visualization, enabling the integration of content from end-user and marketing clients based on the drone's geographic position and social media audience profile.

An unmanned aerial vehicle comprising a rotor having one or more propeller blades and a propeller guard surrounding the rotor. The propeller guard comprises a main guard surrounding the one or more propeller blades and a movable guard vertically displaced from the main guard. The movable guard is movable from a default position to an engaged position by temporarily deforming the movable guard such that the movable guard contacts and obstructs rotation of the one or more propeller blades.

Systems, apparatuses, and methods are provided herein for unmanned flight optimization. A system for unmanned flight comprises a set of motors configured to provide locomotion to an unmanned aerial vehicle, a set of wings coupled to a body of the unmanned aerial vehicle via an actuator and configured to move relative to the body of the unmanned aerial vehicle, a sensor system on the unmanned aerial vehicle, and a control circuit.
