A lightweight, pocket-sized unmanned aerial vehicle (UAV) that can be held in an outstretched hand by a user for take-off and landing of the UAV. The UAV comprises a semi-toroidal or a substantially toroidal hollow body that defines a duct. The UAV further comprises a motor for rotating a fan that directs air into and out of the duct enabling UAV to take flight. The UAV comprises a flight-control system that comprises at least two flight control surfaces that can alter the directed air as it flows through the duct for controlling the roll and pitch and optionally the yaw of the UAV during flight. The flight control system may be controlled by a microprocessor controller. The UAV further comprises a payload, with at least a wireless transmitter and receiver unit.

A flapping wing driving apparatus includes at least one crank gear capstan rotatably coupled to a crank gear, the at least one crank gear capstan disposed radially offset from a center of rotation of the crank gear; a first wing capstan coupled to a first wing, the first wing capstan having a first variable-radius drive pulley portion; and a first drive linking member configured to drive the first wing capstan, the first drive linking member windably coupled between the first variable-radius drive pulley portion and one of the at least one crank gear capstan; wherein the first wing capstan is configured to non-constantly, angularly rotate responsive to a constant angular rotation of the crank gear.

The present disclosure describes a signal relay node that is physically displaceable by a delivery system to move the signal relay node to a different location, to enable the signal relay node to overcome physical obstructions to signal propagation. A delivery system, such as a launching system, can launch the signal relay node encased within a housing unit, such as a projectile cap. Upon launch into the air, an additional aloft package may provide an aerostat, parachute, and/or a propeller and motor system to keep the signal relay node aloft in the air for a longer period of time.

A bio-hybrid odor-localizing autonomous air vehicle includes an airborne robotic platform having a navigation platform, a wireless transmitter communicatively coupled to a management console, and a biological sensor mounted on the airborne robotic platform that reacts to at least one olfactory odor. A controller is communicatively coupled to the airborne robotic platform, the navigation platform, and the biological sensor. The controller monitors the biological sensor. In response to the biological sensor detecting the at least one olfactory odor, the controller directs the airborne platform to three-dimensionally map an olfactory plume of the at least one olfactory odor using an olfactory-driven search pattern. The controller stores the three-dimensional map for later retrieval or transmits the three-dimensional map of the olfactory plume to the management console via the wireless transmitter.

The disclosure relates to a biomimetic insect. The biomimetic insect includes a trunk and at least two wings connected to the trunk. The wing includes a carbon nanotube layer and a vanadium dioxide layer (VO.sub.2) layer stacked with each other. Because the drastic, reversible phase transition of vanadium dioxide, the wing has giant deformation amplitude and fast response.

A method and apparatus for scalable and fast deployment of drones are presented. The method is based on packing multiple drones within a cell structure that provides means for changing, communication and fast deployment of drones as well as environmental protection. Multiple cells can be combined the further scale up the number and rate of drones being deployed. In a preferable arrangement, individual drones are equipped with special contacts that allow them to connect to the cell and optionally with other drones for power supply, diagnostic and communication.

A controller monitors for an activation condition through a monitoring interface of a wearable aerial device. In response to detecting the activation condition through the monitoring interface, the controller triggers the wearable aerial device to release from an aesthetic attachment proximate to a user and hover a distance above the user of a height above a selected height threshold. The controller analyzes a recording of content by the wearable aerial device to assess a particular threat level associated with the content from among multiple threat levels. The controller, in response to the particular threat level exceeding a threat threshold, automatically sends a communication to one or more emergency contacts.

The present invention discloses a method of automatic agricultural pollination based on a micro air vehicle, with detailed steps as follows: in a current pollination working area j, a central control system CCS assigning a work task to a micro air vehicle pollinator MAVi; capturing a data of flower via a camera and a data acquisition device; processing an original data collected from a specific data source, and then screening, filtering and preprocessing the original data; according to a data flow, performing an operation of recognizing flower; assessing whether a designated flower is successfully recognized or not; the micro air vehicle pollinator MAVi pollinating the designated flower; assessing a pollination result and an effectiveness of the micro air vehicle pollinator MAVi, and determining whether to end a work of the current working area j and to enter into the next working area j+1 or not. The present invention is more efficient in an automatic process, reducing an operating cost at the same time, being advantageous for propelling intellectualization, and the present invention can provide a higher efficiency and a better pollination quality and improve an agricultural productivity.

A coupling mechanism for coupling a light vehicle to a surface, the coupling mechanism comprising: a magnetic coupling device arranged such that it may be switched between a first mode and a second mode, wherein in the first mode the device generates an external magnetic field less than a first strength, and in the second mode the device generates an external magnetic field of at least a second strength, the second strength being greater than the first strength; and a surface detection unit, coupled to the magnetic coupling device, and arranged to determine when the light vehicle is within a predetermined distance of a surface, wherein in response to the surface detection unit determining that the light vehicle is within the predetermined distance, switching the magnetic coupling device from the first mode to the second mode, to secure the light vehicle to the surface.

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.
