BACKGROUNDAn unmanned aerial vehicle (UAV) is an aircraft without a human pilot aboard. A UAV's flight may be controlled either autonomously by onboard computers or by remote control of a pilot on the ground or in another vehicle. A UAV is typically launched and recovered via an automatic system or an external operator on the ground. There are a wide variety of UAV shapes, sizes, configurations, characteristics, etc. UAVs may be used for a growing number of civilian applications, such as police surveillance, firefighting, security work (e.g., surveillance of pipelines), surveillance of farms, commercial purposes, etc.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTSThe following detailed description refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.
Some private companies propose using UAVs for rapid delivery of lightweight commercial products (e.g., packages), food, medicine, etc. Such proposals for UAVs may need to meet various requirements, such as federal and state regulatory approval, public safety, reliability, individual privacy, operator training and certification, security (e.g., hacking), payload thievery, logistical challenges, etc.
FIGS. 1A and 1B are diagrams of an overview of anexample implementation100 described herein. Inexample implementation100, assume that a first user device (e.g., user device A) is associated with a first user (e.g., user A) that is located at an origination location (e.g., location A), as shown inFIG. 1A. Further, assume that user A wants to fly a UAV from location A to a mobile destination location in order to deliver a package to a second user (e.g., user B) associated with a second user device (e.g., user device B) and travelling in a car. As further shown inFIG. 1A, a UAV platform or system may be associated with data storage, and the UAV platform and the data storage may communicate with networks, such as a wireless network, a satellite network, and/or other networks. The networks may provide information to the data storage, such as capability information associated with UAVs (e.g., thrust, battery life, etc. associated with UAVs); weather information associated with a geographical region that includes geographical locations of location A, location B, and locations between location A and location B; air traffic information associated with the geographical region; obstacle information (e.g., buildings, mountains, etc.) associated with the geographical region; regulatory information (e.g., no fly zones, government buildings, etc.) associated with the geographical region; historical information (e.g., former flight paths, former weather, etc.) associated with the geographical region; etc.
As further shown inFIG. 1A, user A may instruct user device A (or the UAV) to generate a request for a flight path (e.g., from location A to a location of user device B) for the UAV, and to provide the request to the UAV platform. The request may include credentials (e.g., a serial number, an identifier of a universal integrated circuit card (UICC), etc.) associated with the UAV. The UAV platform may utilize the UAV credentials to determine whether the UAV is authenticated for utilizing the UAV platform and/or one or more of the networks, and is registered with an appropriate authority (e.g., a government agency) for use. For example, the UAV platform may compare the UAV credentials with UAV account information (e.g., information associated with authenticated and registered UAVs) provided in the data storage to determine whether the UAV is authenticated. Assume that the UAV is authenticated for the UAV platform, and that the UAV platform provides, to the networks, a message indicating that the UAV is authenticated. The UAV may connect with the networks based on the authentication of the UAV, as further shown inFIG. 1A.
The UAV platform may utilize information associated with the UAV (e.g., information regarding components of the UAV, the requested flight path, etc.) to identify capabilities of the UAV, and other information in the data storage. For example, the UAV platform may retrieve capability information associated with the UAV and/or other information (e.g., the weather information, the obstacle information, the regulatory information, the historical information, etc. associated with the geographical region) from the data storage. The UAV platform may calculate the flight path from location A to the location of user device B based on the capability information, the other information, and/or information associated with a current location, a direction of travel, and/or a speed of user device B. The UAV platform may generate flight path instructions for the flight path. For example, the flight path instructions may indicate that the UAV is to fly at an altitude of two-thousand (2,000) meters, for fifty (50) kilometers and fifty-five (55) minutes, and then is to fly at an altitude of one-thousand (1,000) meters, for seventy (70) kilometers and one (1) hour in order to arrive at the location of user device B.
In some implementations, the UAV platform may anticipate a particular location where user device B will be in a particular amount of time (e.g., that takes into account a time for the UAV to travel to the particular location) based on the current location, the direction of travel, and/or the speed of user device B. In some implementations, the UAV platform may take current or historical traffic conditions into account when determining the particular location.
As shown inFIG. 1B, the UAV platform may provide the flight path instructions to the UAV (e.g., via the networks). As further shown, the UAV may take off from location A, and may travel the flight path based on the flight path instructions. While the UAV is traveling along the flight path, one or more of the networks may receive feedback from user device B (e.g., about user device B changing speed, direction of travel, etc.). Assume that user device B provides, via the feedback, information about a new location of user device B (e.g., new mobile location B). The UAV platform and/or the UAV may calculate a modified flight path that enables the UAV to arrive at new mobile location B.
The UAV platform and/or the UAV may generate modified flight path instructions for the modified flight path. The UAV platform may provide the modified flight path instructions to the UAV. The UAV may travel the modified flight path, based on the modified flight path instructions. When the UAV arrives at new mobile location B, the UAV and/or user device B may generate a notification indicating that the UAV arrived safely at new mobile location B, and may provide the notification to the UAV platform. The UAV may provide the package to user B and may return to location A via a return flight path (e.g., calculated by the UAV platform).
Systems and/or methods described herein may provide a platform that enables UAVs to safely traverse flight paths from origination locations to destination locations. The systems and/or methods may enable the UAVs to travel to destination locations that are moving, such as to locations associated with users traveling in vehicles. The systems and/or methods may enable the platform to calculate flights paths that ensure that the UAVs rendezvous with users associated with mobile destination locations.

In some implementations,UAV platform230 may receive, fromUAV220, a request for a flight path from an origination location to a mobile destination location (e.g., a location of a mobile user device210).UAV platform230 may authenticateUAV220 for use ofUAV platform230 and/or networks240-260 based on the credentials, and may determine capability information forUAV220 based on the request and/or component information associated withUAV220.UAV platform230 may receive a current location, a direction of travel, and/or a speed of themobile user device210, and may calculate the flight path from the origination location to the destination location based on the capability information, other information (e.g., weather information, air traffic information, etc.), and/or the current location, the direction of travel, and/or the speed of themobile user device210.UAV platform230 may generate flight path instructions for the flight path, and may provide the flight path instructions toUAV220.UAV platform230 may receive feedback fromUAV220 and themobile user device210, via networks240-260, during traversal of the flight path byUAV220.UAV platform230 may modify the flight path instructions based on the feedback, and may provide the modified flight path instructions toUAV220.UAV platform230 may receive a notification thatUAV220 arrived at the location of themobile user device210 whenUAV220 lands at the mobile destination location.
In some implementations,UAV platform230 may determine an array of prearranged destination locations (e.g., locations to rendezvous with the mobile user device210), and the user of themobile user device210 may select one of the prearranged destination locations. In some implementations,UAV220 may arrive at a mobile location of the mobile user device210 (e.g., within a moving emergency vehicle) and may take into account all safety considerations (e.g., safety of passengers in the emergency vehicle, safety of other vehicles, etc.).
In some implementations,UAV platform230 may authenticate one or more users, associated withuser device210 and/orUAV220, for utilizingUAV platform230, and may securely store authentication information associated with the one or more users. In some implementations,UAV platform230 may adhere to requirements to ensure thatULAVs220 safely traverse flight paths, and may limit the flight paths ofUAVs220 to particular safe zones (e.g., particular altitudes, particular geographical locations, particular geo-fencing, etc.) to further ensure safety.
Data storage235 may include one or more storage devices that store information in one or more data structures, such as databases, tables, lists, trees, etc. In some implementations,data storage235 may store information, such as UAV account information (e.g., serial numbers, model numbers, user names, etc. associated with UAVs220); capability information associated with UAVs220 (e.g., thrust, battery life, etc. associated with UAVs220); weather information associated with a geographical region (e.g., precipitation amounts, wind conditions, etc.); air traffic information associated with the geographical region (e.g., commercial air traffic,other UAVs220, etc.); obstacle information (e.g., buildings, mountains, towers etc.) associated with the geographical region; regulatory information (e.g., no fly zones, government buildings, etc.) associated with the geographical region; historical information (e.g., former flight paths, former weather conditions, etc.) associated with the geographical region; etc. In some implementations,data storage235 may be included withinUAV platform230.

The EPC network may include an all-Internet protocol (IP) packet-switched core network that supports high-speed wireless and wireline broadband access technologies. The EPC network may allowuser devices210 and/orUAVs220 to access various services by connecting to the LTE network, an evolved high rate packet data (eHIRPD) radio access network (RAN), and/or a wireless local area network (WLAN) RAN. The IMS network may include an architectural framework or network (e.g., a telecommunications network) for delivering IP multimedia services. The PDN may include a communications network that is based on packet switching. In some implementations,wireless network240 may provide location information (e.g., latitude and longitude coordinates) associated withuser devices210 and/orUAVs220. For example,wireless network240 may determine a location ofuser device210 and/orUAV220 based on triangulation of signals, generated byuser device210 and/orUAV220 and received by multiple cell towers, with prior knowledge of the cell tower locations.

In some implementations, one or more of the devices ofenvironment200 may include one ormore devices300 or one or more components ofdevice300. As shown inFIG. 3,device300 may include abus310, aprocessor320, amemory330, astorage component340, aninput component350, anoutput component360, and acommunication interface370.

In practice,device300 may include additional components, fewer components, different components, or differently arranged components than those shown inFIG. 3.

FIGS. 4A and 4B depict a flow chart of anexample process400 for determining a flight path for a UAV to a mobile destination. In some implementations, one or more process blocks ofFIGS. 4A and 4B may be performed byUAV platform230. In some implementations, one or more process blocks ofFIGS. 4A and 4B may be performed by another device or a group of devices separate from or includingUAV platform230, such asuser device210 and/orUAV220.
As shown inFIG. 4A,process400 may include receiving, from a UAV, a request for a flight path from a location of the UAV to a location of a mobile device, and credentials of the UAV (block405). For example,UAV platform230 may receive, fromUAV220, a request for a flight path from a location ofUAV220 to a location of amobile user device210, and credentials associated withUAV220. In some implementations, themobile user device210 or anotheruser device210 may provide information associated with the flight path toUAV220, andUAV220 may provide the request for the flight path toUAV platform230. In some implementations, the request for the flight path may be provided by themobile user device210 or theother user device210 toUAV platform230. In some implementations, the request for the flight path may include a request for flight path instructions from an origination location (e.g., a current location of UAV220) to a mobile destination location (e.g., a location of the mobile user device210). The origination location and the mobile destination location may be provided in a particular region. In some implementations, the credentials ofUAV220 may include an identification number, a model number, a serial number, an identifier of a UICC (or another type of smart card), a government registration number, a private encryption key, a public encryption key, a certificate, etc. associated withUAV220. In some implementations, the credentials ofUAV220 may include information identifying components of UAV220 (e.g., serial numbers, model numbers, part numbers, etc. of the components).
As further shown inFIG. 4A,process400 may include determining whether the UAV is authenticated for network(s) and is registered with an appropriate authority based on the UAV credentials (block410). For example,UAV platform230 may determine whetherUAV220 is authenticated for usingUAV platform230 and/or one or more of networks240-260 based on the credentials ofUAV220. In some implementations,UAV platform230 may compare the credentials ofUAV220 with UAV account information stored in data storage235 (e.g., information associated with authenticated and registeredUAVs220, such as identification numbers ofUAVs220, public and/or private encryption keys ofUAVs220, account status information, etc.) in order to determine whetherUAV220 is authenticated for usingUAV platform230 and/or one or more of networks240-260. For example, if the credentials ofUAV220 include a serial number ofUAV220,UAV platform230 may compare the serial number to the UAV account information indata storage235 to determine whetherUAV220 is registered withUAV platform230, whether an account ofUAV220 is in good standing (e.g., paid for), etc. In some implementations,UAV platform230 may determine whetherUAV220 is authenticated for usingUAV platform230 and/or one or more of networks240-260 based on a UICC associated withUAV220.
In some implementations.UAV platform230 may determine whetherUAV220 is registered with an appropriate authority (e.g., a government agency) based on the credentials ofUAV220. For example, if the credentials ofUAV220 include a government registration number ofUAV220,UAV platform230 may compare the government registration number to the UAV account information indata storage235 to determine whetherUAV220 is registered with a government agency to legally fly in airspace regulated by the government agency. In some implementations,UAV220 may include a common protocol withother UAVs220. The common protocol may enableUAV220 to be authenticated for usingUAV platform230 and/or one or more of networks240-260, to communicate with theother UAVs220, and/or to be verified as being registered with an appropriate authority. For example, if aparticular UAV220 is flying in an area where theparticular UAV220 loses communication withwireless network240,UAV220 may establish communications withother UAVs220 located near the particular UAV220 (e.g., via the common protocol). Theother UAVs220 may share information (e.g., received from wireless network240) with theparticular UAV220 via the communications.
As further shown inFIG. 4A, if the UAV is not authenticated for the network(s) and/or is not registered with an appropriate authority (block410—NO),process400 may include denying the request for the flight path (block415). For example, ifUAV platform230 determines thatUAV220 is not authenticated for usingUAV platform230 and/or one or more of networks240-260 based on the credentials ofUAV220,UAV platform230 may deny the request for the flight path. In some implementations,UAV platform230 may provide, toUAV220, a notification indicating that the request for the flight path is denied due toUAV220 not being authenticated for usingUAV platform230 and/or one or more of networks240-260. In some implementations,UAV platform230 may determine thatUAV220 is not authenticated for usingUAV platform230 and/or one or more of networks240-260 whenUAV220 is not registered withUAV platform230, an account ofUAV220 is not in good standing, etc.
Additionally, or alternatively, ifUAV platform230 determines thatUAV220 is not registered with an appropriate authority based on the credentials ofUAV220,UAV platform230 may deny the request for the flight path. In some implementations,UAV platform230 may provide, toUAV220, a notification indicating that the request for the flight path is denied due toUAV220 not being registered with an appropriate authority. In some implementations.UAV platform230 may determine thatUAV220 is not registered with an appropriate authority whenUAV220 fails to provide a government registration number via the credentials ofUAV220.
As further shown inFIG. 4A, if the UAV is authenticated for the network(s) and is registered with an appropriate authority (block410—YES),process400 may include determining capability information for the UAV based on the request and component information of the UAV (block420). For example, ifUAV platform230 determines, based on the credentials ofUAV220, thatUAV220 is authenticated for usingUAV platform230 and/or one or more of networks240-260, and is registered with an appropriate authority,UAV platform230 may approve the request for the flight path. In some implementations,UAV platform230 may determine thatUAV220 is authenticated for usingUAV platform230 and/or one or more of networks240-260 whenUAV220 is registered withUAV platform230, an account ofUAV220 is in good standing (e.g., paid for), etc. In some implementations,UAV platform230 may determine thatUAV220 is registered with an appropriate authority whenUAV220 provides a government registration number that matches a government registration number provided indata storage235.
In some implementations, ifUAV platform230 approves the request for the flight path,UAV platform230 may determine capability information forUAV220 based on the request for the flight path and component information of UAV220 (e.g., provided with the request for the flight path). For example,data storage235 may include capability information associated with different components ofUAVs220, such as battery life, thrusts provided by rotors, flight times associated with amounts of fuel, etc. In some implementations,UAV platform230 may utilize the component information of UAV220 (e.g.,UAV220 has a particular type of battery, engine, rotors, etc.) to retrieve the capability information for components ofUAV220 fromdata storage235. For example, ifUAV220 has a particular type of battery and a particular type of rotor,UAV platform230 may determine that the particular type of battery ofUAV220 may provide two hours of flight time and that the particular type of rotor may enableUAV220 to reach an altitude of one-thousand meters.
In some implementations,UAVs220 may be required to follow a maintenance schedule (e.g., for safety purposes), and may need to be certified (e.g., by a government agency) that the maintenance schedule is followed. Such information may be provided in data storage235 (e.g., with the capability information). In some implementations, ifUAV platform230 determines thatUAV220 is authenticated for usingUAV platform230 and/or one or more of networks240-260, and is registered with an appropriate authority,UAV platform230 may still deny the request for the flight path ifUAV platform230 determines thatUAV220 has not properly followed the maintenance schedule. This may enableUAV platform230 to ensure that only properly maintainedUAVs220 are permitted to fly, which may increase safety associated withUAVs220 utilizing airspace.
As further shown inFIG. 4A,process400 may include receiving a current location, a direction of travel, and a speed of the mobile device (block425). For example,UAV platform230 may receive, from themobile user device210, a current location, a direction of travel, and/or a speed associated with themobile user device210. In some implementations, the current location of themobile user device210 may include a current location of themobile user device210, as provided by wireless network240 (e.g., via cell tower triangulation). Additionally, or alternatively, the current location ofmobile user device210 may include a current GPS location of themobile user device210, as provided by satellite network250 (e.g., via GPS satellites). In some implementations, the direction of travel of themobile user device210 may be generated by a component (e.g., a compass or magnetometer) of themobile user device210, and provided toUAV platform230. Additionally, or alternatively, the direction of travel ofmobile user device210 may be determined byUAV platform230 based on prior locations and the current location of themobile user device210. In some implementations, the speed of themobile user device210 may be generated by a component (e.g., an accelerometer) of themobile user device210, and provided toUAV platform230. Additionally, or alternatively, the speed of themobile user device210 may be determined byUAV platform230 based on the prior locations and the current location of themobile user device210. In some implementations,UAV platform230 may receive the current location, the direction of travel, and/or the speed of themobile user device210 from one or more of networks240-260.
For example, assume that themobile user device210 is provided in a vehicle that is traveling at sixty kilometers per hour in a northeast direction and is currently located at a latitude of 39° north and a longitude of750 west. In such an example,UAV platform230 may receive the latitude of 39° north and the longitude of750 west as the current location of themobile user device210; northeast as the direction of travel of themobile user device210; and sixty kilometers per hour as the speed of themobile user device210.
As further shown inFIG. 4A,process400 may include calculating the flight path from the location of the UAV to the anticipated location of the mobile device based on the capability information, other information, and/or the current location, direction of travel, and speed of the mobile device (block430). For example,UAV platform230 may calculate the flight path from the origination location to an anticipated location of themobile user device210, based on the capability information and/or other information (e.g., the weather information, the air traffic information, the obstacle information, the regulatory information, and/or the historical information) stored inUAV platform230 and/ordata storage235, and based on the current location, the direction of travel, and/or the speed associated with themobile user device210. In some implementations,UAV platform230 may determine whether the capability information indicates thatUAV220 may safely complete the flight path from the origination location to the location of themobile user device210 without stopping. IfUAV platform230 determines thatUAV220 cannot safely complete the flight path from the origination location to the anticipated location of themobile user device210 without stopping (e.g., to recharge or refuel).UAV platform230 may determine one or more waypoints along the flight path whereUAV220 may stop and recharge or refuel.
In some implementations,UAV platform230 may calculate the flight path based on the capability information associated withUAV220 and the weather information. For example,UAV platform230 may determine that, without weather issues, the flight path may takeUAV220 two hours to complete at an altitude of five-hundred meters.UAV platform230 may further determine that wind conditions at five-hundred meters may create a headwind of fifty kilometers per hour onUAV220, but that wind conditions at one-thousand meters may create a tailwind of fifty kilometers per hour onUAV220. In such an example,UAV platform230 may alter the flight path from an altitude of five-hundred meters to an altitude of one-thousand meters (e.g., ifUAV220 is capable of reaching the altitude of one-thousand meters). Assume that the tailwind at the altitude of one-thousand meters decreases the flight time from two hours to one hour and thirty minutes. Alternatively,UAV platform230 may not alter the flight path, but the headwind at the altitude of five-hundred meters may increase the flight time from two hours to two hours and thirty minutes.
Additionally, or alternatively,UAV platform230 may calculate the flight path based on the capability information associated withUAV220 and the air traffic information. For example,UAV platform230 may determine that, without air traffic issues, the flight path may takeUAV220 two hours to complete at an altitude of five-hundred meters.UAV platform230 may further determine thatother UAVs220 are flying at the altitude of five-hundred meters based on the air traffic information, but that noother UAVs220 are flying at an altitude of one-thousand meters. In such an example,UAV platform230 may alter the flight path from an altitude of five-hundred meters to an altitude of one-thousand meters. The altitude of one-thousand meters may enableUAV220 to safely arrive at the location without the possibility of colliding withother UAVs220. Alternatively,UAV platform230 may not alter the flight path, but theother UAVs220 flying at the altitude of five-hundred meters may increase possibility thatUAV220 may collide with anotherUAV220.UAV platform230 may then determine whetherUAV220 is capable of safely flying at the altitude of five-hundred meters without colliding with anotherUAV220.
Additionally, or alternatively,UAV platform230 may calculate the flight path based on the capability information associated withUAV220 and the obstacle information. For example,UAV platform230 may determine that, without obstacle issues, the flight path may takeUAV220 one hour to complete at an altitude of two-hundred meters.UAV platform230 may further determine that one or more buildings are two-hundred meters in height based on the obstacle information, but that no other obstacles are greater than two-hundred meters in height. In such an example,UAV platform230 may alter the flight path from an altitude of two-hundred meters to an altitude of three-hundred meters. The altitude of three-hundred meters may enableUAV220 to safely arrive at the location without the possibility of colliding with the one or more buildings. Alternatively,UAV platform230 may not alter the altitude of the flight path, but may change the flight path to avoid the one or more buildings, which may increase the flight time from one hour to one hour and thirty minutes.
Additionally, or alternatively,UAV platform230 may calculate the flight path based on the capability information associated withUAV220 and the regulatory information. For example,UAV platform230 may determine that, without regulatory issues, the flight path may takeUAV220 one hour to complete at an altitude of five-hundred meters.UAV platform230 may further determine that the flight path travels over a restricted facility based on the regulatory information. In such an example,UAV platform230 may change the flight path to avoid flying over the restricted facility, which may increase the flight time from one hour to one hour and thirty minutes.
Additionally, or alternatively,UAV platform230 may calculate the flight path based on the capability information associated withUAV220 and the historical information. For example,UAV platform230 may identify prior flight paths to the location from the historical information, and may select one of the prior flight paths, as the flight path, based on the capability information associated withUAV220. For example, assume thatUAV platform230 identifies three prior flight paths that include flight times of two hours, three hours, and four hours, respectively, and may determine thatUAV220 may safely fly for two hours and thirty minutes (e.g., based on the capability information). In such an example,UAV platform230 may select, as the flight path, the prior flight path with the flight time of two hours.
In some implementations,UAV platform230 may calculate the flight path from the origination location to the anticipated location of themobile user device210 based on the current location, the direction of travel, and/or the speed of themobile user device210. In some implementations,UAV platform230 may determine a waypoint (e.g., an anticipated location of the mobile user device210) for the flight path based on the current location, the direction of travel, and/or the speed of themobile user device210. The waypoint may include a location (e.g., a meeting location) whereUAV220 may rendezvous with themobile user device210 and deliver a payload to a user of themobile user device210. For example,UAV platform230 may determine that themobile user device210 will be at a particular location at a particular time based on the current location, the direction of travel, and/or the speed of themobile user device210. In such an example,UAV platform230 may calculate a flight path that causesUAV220 to arrive at the particular location before or around the particular time that themobile user device210 arrives at the particular location.UAV platform230 may provide, to themobile user device210, a notification indicating thatUAV220 will be at the particular location at the particular time (e.g., so that the user of themobile user device210 may stop at the particular location). In some implementations,UAV platform230 may provide, to themobile user device210, information indicating a proximity ofUAV220 to themobile user device210 so that the user may track the location ofUAV220.
In some implementations,UAV platform230 may determine, for the flight path and based on the current location, the direction of travel, and/or the speed of themobile user device210, thatUAV220 is to descend toward themobile user device210 whenUAV220 is a particular distance away from themobile user device210. For example, assume that themobile user device210 is provided in a vehicle traveling north on an interstate highway, and thatUAV platform230 determines thatUAV220 may fly to a rest stop (e.g., and remain airborne) on the interstate highway ahead of themobile user device210. In such an example, when themobile user device210 is within a particular distance of the rest stop,UAV220 may descend toward a location at the rest stop so that the user of themobile user device210 may receive a payload provided byUAV220.UAV platform230 may also provide, to themobile user device210, information indicating a proximity ofUAV220 to themobile user device210 so that the user may track the location ofUAV220 at the rest stop.
In some implementations,UAV platform230 may calculate, based on the current location, the direction of travel, and/or the speed of themobile user device210, a flight path that includes a destination location where themobile user device210 may retrieve a payload provided byUAV220. For example,UAV platform230 may calculate a destination location (e.g., along an anticipated travel path of the mobile user device210) that is associated with a partner entity, such as, for example, a convenience store, a big chain store, a fast food restaurant, a rest stop, a retail store, a parking lot, a restaurant, a grocery store, etc. An employee for the partner entity may receive a payload provided byUAV220, and may hold the payload until the user of themobile user device210 claims the payload. In such an example,UAV platform230 may provide, to themobile user device210, information indicating a location of the partner entity and a confirmation code (e.g., a bar code, a quick response (QR) code, a word, a numeric code, an alphabetical code, an alphanumeric code, etc.) or an authentication mechanism (e.g., a private and/or public encryption key, a certificate, a password, etc.). The user of themobile user device210 may utilize the confirmation code or the authentication mechanism to authenticate the user (e.g., to the partner entity) so that the user may receive the payload from the partner entity. In some implementations, the partner entity may be rewarded in some manner for accepting payloads on behalf of the user and/or on behalf of owners or operators ofUAVs220.
In some implementations,UAV platform230 may determine, for the flight path and based on the current location, the direction of travel, and/or the speed of themobile user device210, thatUAV220 is to search for a particular wireless local area network (WLAN) (e.g., an IEEE 802.15 (e.g., Bluetooth) network, an IEEE 802.11 (e.g., Wi-Fi) network, a near field communication (NFC) network, etc.) generated by themobile user device210. In such implementations,UAV220 may descend toward themobile user device210 whenUAV220 detects the particular WLAN. For example, themobile user device210 may generate a Wi-Fi signal andUAV220 may traverse the flight path untilUAV220 detects the Wi-Fi signal. WhenUAV220 detects the Wi-Fi signal,UAV220 may descend toward themobile user device210 and deliver the payload to the user of themobile user device210. In another example, if the user ofmobile user device210 is going hiking or mountain climbing in a desolate area, the user may instructUAV platform230 to sendUAVs220 to search for the user if a signal is not received from themobile user device210 for a particular amount of time (e.g., in hours, days, etc.). In such an example, after the particular amount of time, themobile user device210 may generate a Wi-Fi signal, andUAV platform230 may dispatchUAVs220 to search for the user based on the Wi-Fi signal. Such an arrangement may aid in search and rescue missions, especially in areas that are difficult to traverse by foot or by vehicle.
In some implementations,UAV platform230 may calculate the flight path from the origination location to the mobile destination location based on the capability information, the weather information, the air traffic information, the obstacle information, the regulatory information, the historical information, the current location of themobile user device210, the direction of travel of themobile user device210, and/or the speed of themobile user device210.
As further shown inFIG. 4A,process400 may include generating flight path instructions for the flight path (block435). For example,UAV platform230 may generate flight path instructions for the flight path. In some implementations, the flight path instructions may include specific altitudes forUAV220 between fixed geographic coordinates (e.g., a first location and a second location); navigational information (e.g., travel east for three kilometers, then north for two kilometers, etc.); expected weather conditions (e.g., headwinds, tailwinds, temperatures, etc.); network information (e.g., locations of base stations of wireless network240); timing information (e.g., when to take off, when to perform certain navigational maneuvers, etc.); waypoint information (e.g., locations whereUAV220 may stop and recharge or refuel); etc. For example, the flight path instructions may include information that instructsUAV220 to fly forty-five degrees northeast for ten kilometers at an altitude of five-hundred meters, fly three-hundred and fifteen degrees northwest for ten kilometers at an altitude of four-hundred meters, etc.
As shown inFIG. 4B,process400 may include providing the flight path instructions to the UAV (block440). For example,UAV platform230 may provide the flight path instructions toUAV220. In some implementations,UAV220 may utilize the flight path instructions to travel via the flight path. For example,UAV220 may take off at a time specified by the flight path instructions, may travel a route and at altitudes specified by the flight path instructions, may detect and avoid any obstacles encountered in the flight path, etc. untilUAV220 arrives at the location of themobile user device210.
In some implementations, ifUAV220 includes sufficient computational resources (e.g., a sufficient degree of autonomy),UAV220 may utilize information provided by the flight path instructions to calculate a flight path forUAV220 and to generate flight path instructions. In such implementations, the flight path instructions provided byUAV platform230 may include less detailed information, andUAV220 may determine more detailed flight path instructions via the computational resources ofUAV220.
As further shown inFIG. 4B,process400 may include receiving feedback from the UAV and/or the mobile device, via network(s), during traversal of the flight path by the UAV (block445). For example, whileUAV220 is traveling along the flight path in accordance with the flight path instructions,UAV220 and/or themobile user device210 may provide feedback toUAV platform230 via one or more of networks240-260, andUAV platform230 may receive the feedback. In some implementations, the feedback may include information received by sensors ofUAV220, such as visual information received from electromagnetic spectrum sensors of UAV220 (e.g., images of obstacles), temperature information, wind conditions, etc. In some implementations,UAV220 may utilize such feedback to detect and avoid any unexpected obstacles encountered byUAV220 during traversal of the flight path. For example, ifUAV220 detects anotherUAV220 in the flight path,UAV220 may alter the flight path to avoid colliding with theother UAV220.
In some implementations, the feedback may include updates to the current location, the direction of travel, and/or the speed of themobile user device210. For example, if themobile user device210 is provided in a moving vehicle, the current location of themobile user device210 may constantly be updated and provided toUAV platform230 via the feedback. In another example, if the moving vehicle changes directions from north to east, the direction of travel of themobile user device210 may be updated (e.g., from north to east) and provided toUAV platform230 via the feedback. In still another example, if the moving vehicle slows down from fifty kilometers per hour to ten kilometers per hour, the speed of themobile user device210 may be updated (e.g., from fifty to ten kilometers per hour) and provided toUAV platform230 via the feedback.
As further shown inFIG. 4B,process400 may include determining whether to modify the flight path based on the feedback from the UAV and/or the mobile device (block450). For example,UAV platform230 may determine whether to modify the flight path based on the feedback. In some implementations,UAV platform230 may determine to not modify the flight path if the feedback indicates thatUAV220 will safely arrive at the location of themobile user device210. In some implementations,UAV platform230 may determine to modify the flight path if the feedback indicates thatUAV220 is in danger of colliding with an obstacle (e.g., anotherUAV220, a building, an airplane, etc.). In such implementations,UAV platform230 may modify the flight path so thatUAV220 avoids colliding with the obstacle and/or remains a safe distance from the obstacle.
In some implementations,UAV platform230 may determine to modify the flight path if the feedback indicates that the weather conditions may preventUAV220 from reaching the location of themobile user device210. For example, the wind conditions may change and cause the flight time ofUAV220 to increase to a point where the battery ofUAV220 will be depleted beforeUAV220 reaches the location of themobile user device210. In such an example,UAV platform230 may modify the flight path so thatUAV220 either stops to recharge or changes altitude to improve wind conditions. In another example, rain or ice may increase the weight ofUAV220 and/or its payload and may cause the battery ofUAV220 to work harder to a point where the battery ofUAV220 will be depleted beforeUAV220 reaches the location of themobile user device210. In such an example,UAV platform230 may modify the flight path so thatUAV220 stops to recharge before completing the flight path.
In some implementations,UAV platform230 may determine to modify the flight path if the feedback indicates that the direction of travel and/or the speed of themobile user device210 has changed. For example, if themobile user device210 is provided in a moving vehicle that changes directions from north to east, the original flight path may causeUAV220 to not rendezvous with themobile user device210. In such an example,UAV platform230 may modify the flight path so thatUAV220 travels in a direction (e.g., east instead of north) that enablesUAV220 to rendezvous with themobile user device210. In another example, if the moving vehicle slows down from fifty kilometers per hour to ten kilometers per hour, the original flight path may causeUAV220 to fly too far ahead of themobile user device210. In such an example,UAV platform230 may modify the flight path so thatUAV220 slows down to ensure thatUAV220 does not fly too far ahead of the mobile user device210 (e.g., and rendezvous with the mobile user device210).
As further shown inFIG. 4B, if the flight path is to be modified (block450—YES),process400 may include generating modified flight path instructions based on the feedback (block455). For example, ifUAV platform230 determines that the flight path is be modified,UAV platform230 may modify the flight path based on the feedback (e.g., as described above). In some implementations,UAV platform230 may generate modified flight path instructions for the modified flight path based on the feedback. In some implementations, the modified flight path instructions may modify the flight path instructions based on the feedback. For example, the flight path instructions may be modified so thatUAV220 avoids colliding with an obstacle and/or remains a safe distance from the obstacle, stops to recharge, changes altitude to improve wind conditions, etc. In another example, the flight path instructions may be modified so thatUAV220 changes direction (e.g., to match a directional change of the mobile user device210) and rendezvous with themobile user device210.
As further shown inFIG. 4B,process400 may include providing the modified flight path instructions to the UAV (block460). For example,UAV platform230 may provide the modified flight path instructions toUAV220. In some implementations,UAV220 may utilize the modified flight path instructions to travel along the modified flight path. For example,UAV220 may stop and recharge according to the modified flight instructions, may adjust a route and/or altitudes according to the modified flight path instructions, may detect and avoid any obstacles encountered in the modified flight path, etc. untilUAV220 arrives at the location of themobile user device210. In some implementations,UAV220 may continue to provide further feedback toUAV platform230 during traversal of the modified flight path, andUAV platform230 may or may not further modify the flight path based on the further feedback.
As further shown inFIG. 4B,process400 may include receiving a notification that the UAV arrived at the location of the mobile device (block465). For example,UAV220 may continue along the flight path (or the modified flight path) based on the flight path instructions (or the modified flight path instructions) untilUAV220 arrives at the location themobile user device210. WhenUAV220 arrives at the location of themobile user device210,UAV220 may provide a notification toUAV platform230, via one or more of networks240-260. In some implementations, the notification may indicate thatUAV220 has safely arrived at the location of themobile user device210. Additionally, or alternatively, themobile user device210 may generate the notification, and may provide the notification toUAV platform230.
AlthoughFIGS. 4A and 4B shows example blocks ofprocess400, in some implementations,process400 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted inFIGS. 4A and 4B. Additionally, or alternatively, two or more of the blocks ofprocess400 may be performed in parallel.
FIGS. 5A-5E are diagrams of an example500 relating toexample process400 shown inFIGS. 4A and 4B. Assume that a first user device210 (e.g., a tablet210) is associated with a first user (e.g., an employee at a delivery company) that is located at an origination location (e.g., Washington, D.C.), as shown inFIG. 5A. Further, assume that a second user device210 (e.g., a smart phone210) is associated with a second user (e.g., Bob) that is currently located at a location (e.g., Fairfax, Va.), but is traveling in a car in a particular direction (e.g., towards Gainesville, Va.). Previously, assume that Bob instructedsmart phone210 to request delivery of a package to Bob based on a current location of smart phone210 (e.g., a mobile destination location). For example,smart phone210 may inform tablet210 (e.g., via one or more servers associated with the delivery company) and the employee that the package is to be delivered to Bob at an anticipated location ofsmart phone210. Further, assume that the employee wants to utilizeUAV220 to fly the package from Washington, D.C. to the anticipated location ofsmart phone210 in order to deliver the package to Bob.
As further shown inFIG. 5A,UAV platform230 anddata storage235 may communicate withwireless network240,satellite network250, and/orother networks260.Wireless network240,satellite network250, and/orother networks260 may provide, todata storage235,information505, such as capability information associated withUAV220, weather information associated with a geographical region (e.g., that includes a geographical location of Washington, D.C., a geographical location of Fairfax, Va., and geographical locations between and around Washington and Fairfax), air traffic information associated with the geographical region, obstacle information associated with the geographical region, regulatory information associated with the geographical region, historical information associated with the geographical region, etc.
As further shown inFIG. 5A, the employee may instruct tablet210 (or UAV220) to generate arequest510 for a flight path (e.g., from Washington, D.C. to the location of smart phone210) forUAV220, and to providerequest510 toUAV platform230.Request510 may include credentials515 (e.g., a serial number, an identifier of a UICC, etc. of UAV220) associated withUAV220, orcredentials515 may be provided separately fromrequest510 toUAV platform230.UAV platform230 may utilizecredentials515 to determine whetherUAV220 is authenticated for utilizingUAV platform230 and/or one or more of networks240-260, and is registered with an appropriate authority for use. For example,UAV platform230 may comparecredentials515 with information provided indata storage235 in order to determine whetherUAV220 is authenticated for utilizingUAV platform230 and/or one or more of networks240-260, and is registered with an appropriate authority.
As shown inFIG. 5B,UAV platform230 may retrievecapability information520 associated withUAV220 and other information525 (e.g., weather information, air traffic information, obstacle information, regulatory information, and/or historical information) fromdata storage235 based on component information of UAV220 (e.g., provided with request510). As further shown, assume thatUAV platform230 determines thatUAV220 is authenticated for utilizingUAV platform230 and/or one or more of networks240-260, and is registered with an appropriate authority, as indicated byreference number530. Further, assume thatUAV platform230 provides, to networks240-260, amessage535 indicating thatUAV220 is authenticated to use one or more of networks240-260.UAV220 may connect with one or more of networks240-260 based on the authentication ofUAV220, as indicated byreference number540.
As shown inFIG. 5C,UAV platform230 may receive, fromsmart phone210 and via one or more of networks240-260, a current location, a direction of travel, and a speed associated withsmart phone210, as indicated byreference number545.UAV platform230 may calculate aflight path550 from Washington. D.C. to the anticipated location ofsmart phone210 based oncapability information520,other information525, and/or the current location, the direction of travel, and/or the speed associated withsmart phone210. As further shown inFIG. 5C,UAV platform230 may generateflight path instructions555 forflight path550, and may provideflight path instructions555 toUAV220, via one or more of networks240-260.Flight path instructions555 may includeinformation instructing UAV220 to fly north at zero degrees for ten kilometers, fly northeast at forty degrees for three kilometers, at an altitude of one-thousand meters, etc.UAV220 may take off from Washington, D.C., and may travelflight path550 based onflight path instructions555.
WhileUAV220 is traveling alongflight path550, assume that the car, in which Bob andsmart phone210 are traveling, changes direction and begins heading toward another direction (e.g., towards Vienna, Va.), as shown inFIG. 5D.Smart phone210 may provideinformation560 associated with the direction change toUAV platform230, via one or more of networks240-260.UAV platform230 and/orUAV220 may calculate a modifiedflight path565 based oninformation560.Modified flight path565 may enableUAV220 to accommodate for the direction change ofsmart phone210. As further shown inFIG. 5D,UAV platform230 and/orUAV220 may generate modifiedflight path instructions570 for modifiedflight path565.UAV platform230 may provide modifiedflight path instructions570 to UAV220 (e.g., via one or more of networks240-260).UAV220 may travel modifiedflight path565 based on modifiedflight path instructions570.
As shown inFIG. 5E,UAV platform230 may providenavigation information575 tosmart phone210, via one or more of networks240-260, andsmart phone210 may displaynavigation information575 to Bob.Navigation information575 may provide, to Bob, a location whereUAV220 will meet Bob so that Bob may receive the package (e.g., at a rest stop along a highway in Vienna, Va.).UAV220 may travel to the location specified by navigation instructions575 (e.g., the rest stop in Vienna, Va.), and may meet Bob. WhenUAV220 arrives at the location specified bynavigation instructions575,UAV220 may leave the package at a location where Bob may retrieve the package.UAV220 and/or smart phone210 (e.g., via Bob's input or detection of the presence of UAV220) may generate anotification580 indicating that the package was received by Bob, and may providenotification580 toUAV platform230. After delivering the package to Bob.UAV220 may traverse a return flight path585 (e.g., provided byUAV platform230 to UAV220) untilUAV220 arrives back at the origination location in Washington, D.C.
As indicated above,FIGS. 5A-5E are provided merely as an example. Other examples are possible and may differ from what was described with regard toFIGS. 5A-5E.
