(10) Referring to FIG. 1, an isometric view of an example drone 100 of the system of the present disclosure is shown, the drone comprising a main drone body 102 with a relay drone 104 attached to it.

(11) The main drone 102 is a standard quadcopter design in the present example, though various other types of drone design can be used. The main drone comprises a housing 106 that surrounds the electronics in the main body, four arms 108 that extend outward and support the propellers 110. The housing 106 contains a power source, onboard controller, and the various other circuitry required for flight and surveillance. The functioning of quadcopter drones is well known in the art and will not be elaborated on in depth in this application.

(12) A sensor array of the drone includes a high-definition video camera 112 and one or more motion sensors 114.

(13) In the present example, the relay drone 104 is installed in a cavity on the top of the main drone's exterior body. The arms 116 of the relay drone are folded inwards to lie flat along the exterior profile while not deployed.

(14) Referring to FIG. 2, an isometric view is shown of the relay drone 104 deploying from the main drone 102, the arms 116 of the relay drone folding outwards so that its own propellers 118 can extend and spin to propel, it through the air.

(15) The cavity 120 configured to be seen in this second depiction as being shaped to accommodate the relay drone. The cavity 120 may be designed as being wider and of larger volume than the relay drone itself to compensate for small misalignments when the relay drone returns to and re-couples to the cavity mid-air. A plurality of electromagnets may be installed about the cavity 120 to engage/disengage the relay drone. Proximity sensors may also be installed in and around cavity 120 and on the relay drone 104 to help coordinate mid-air deployment and re-attachment.

(16) Referring to FIG. 3, drone couple 100 is shown in communication with a remote-control device 200 and headpiece display 300.

(17) The remote-control device has a first toggle 202 and second toggle 204 for controlling various aspects of flight such as tilt and rotation, and a pair of graded switches 206 and 208 for controlling the thrust/RPM of the propellers, as is known in the art. The relay drone is flown autonomously, so no controls are needed.

(18) The headpiece 300 in the present example is designed as a fully encompassing headset with a pair of goggles installed in the interior and a strap for holding it on the wearer's head in the fashion of virtual reality devices.

(19) The onboard controller of the main drone 102 is configured to transmit data captured by the camera 112 of its sensor array to the wearable headpiece 300, including a set of video data to be displayed on the display of the headpiece so that a wearer has a first-person view of the main drone's surroundings. This allows a user to quickly and intuitively scan the environment of the drone while holding the remote-control device 200 and directing it.

(20) The processors of both the main drone 102 and the relay drone 104 are configured with navigation algorithms configured to deploy and fly the relay drone 104 from the main drone in coordinated flight to relay signals between the remote control 200/headpiece 300 and the main drone through the relay drone 104 in response to a detection of the main drone leaving communications range of the remote control and headpiece. This may involve a complete loss of signal or simply poor signal quality. For example, if the main drone moves behind an object the signal may be lost completely, but if it is just slightly out of the optimum communications range from the user the signal quality will merely deteriorate, and the relay drone configured to be used as a signal booster.

(21) The controller 200 or headpiece 300 may also be equipped with a microphone and two-way radio connected to a corresponding radio and speaker device on the main drone, allowing a user to convey their voice to an environment in the immediate vicinity of the main drone, for example, to warn trespassers to leave property under surveillance by the drone.

(22) Referring to FIG. 4, a user is shown wearing the headpiece 300 and holding the remote control 200 to operate the main drone 102 which is behind obstacle 400, with the relay drone 104 autonomously positioning itself to maintain the best signal strength.

(23) The navigation algorithms for coordinating flight between the relay drone 102 and main drone 104 may comprise an artificial intelligence algorithm configured to optimize the signal between the main drone and the headpiece and remote control. Both drones may similarly be equipped with motion sensors and artificial intelligence for autonomous obstacle avoidance.

(24) The navigation algorithms on the drone can cause it to act autonomously, such as for example causing it to fly a predetermined route entered by a user on a regular basis, or to randomly patrol a predetermined area including one or more checkpoints that it must pass by.

(25) The system may also for example include one or more separate stationary motion detectors which can be placed about a predetermined area, the motion detectors each comprising a wireless communications module configured to send an alert signal to the main drone 102 in response to a motion detection, and the main drone 102 being programmed to autonomously launch and survey the area around the motion detector in response to said signal.

(26) The main drone may also be connected to the internet, uploading video data and other sensed environmental data to one or more servers accessible via the cloud or dedicated application software on user's mobile devices.

(27) The wireless communications include, by way of example and not of limitation, CDMA, WCDMA, GSM, UMTS, or any other wireless communication system such as wireless local area network (WLAN), Wi-Fi or WiMAX.

(28) It should be understood that the operations described herein, in particular the communications between the drone system and user devices such as smartphones, may be carried out by any processor.

(29) In particular, the operations may be carried out by, but are not limited to, one or more computing environments used to implement the method such as a dedicated hosting environment, and/or one or more other computing environments in which one or more assets used by the method re implemented; one or more computing systems or computing entities used to implement the method; one or more virtual assets used to implement the method; one or more supervisory or control systems, such as hypervisors, or other monitoring and management systems, used to monitor and control assets and/or components; one or more communications channels for sending and receiving data used to implement the method; one or more access control systems for limiting access to various components, such as firewalls and gateways; one or more traffic and/or routing systems used to direct, control, and/or buffer, data traffic to components, such as routers and switches; one or more communications endpoint proxy systems used to buffer, process, and/or direct data traffic, such as load balancers or buffers; one or more secure communication protocols and/or endpoints used to encrypt/decrypt data, such as Secure Sockets Layer (SSL) protocols, used to implement the method; one or more databases used to store data; one or more internal or external services used to implement the method; one or more backend systems, such as backend servers or other hardware used to process data and implement the method; one or more software systems used to implement the method; and/or any other assets/components in which the method is deployed, implemented, accessed, and run, e.g., operated, as discussed herein, and/or as known in the art at the time of filing, and/or as developed after the time of filing.
