Description

SHJ623 POW004 ver 2 - 1 - 266248/2 A UAV CARRIER TECHNICAL FIELD The invention relates to an Unmanned Aerial Vehicle (UAV) carrier.

BACKGROUND UAVs are commonly used nowadays to take part or to accomplish various missions or tasks that in the past required manned aircrafts. These missions may include civilian missions, such as: disaster relief, archeology, conservation (pollution monitoring, anti-poaching, etc.), law enforcement, and anti-terrorism missions. Commercial missions, such as: aerial surveillance, filmmaking, journalism, scientific research, surveying, cargo transport, and agriculture and many other relevant missions, that can be accomplished by an unmanned aircraft.

The UAVs may be fully autonomous in fulfilling their missions, they may be remotely piloted UAVs, controlled by human controllers from afar or they may have partial autonomous capabilities, requiring human intervention in some aspects of their mission.

Due to limitations in the amount of energy and in mission flight time of many UAVs, there is a need to carry at least one UAV to a geographical vicinity of a mission area, thereby eliminating the need for the at least one UAV to fly by consuming its own limited powers to the mission area. There is thus a need for a UAV carrier.

The UAV may rely on Global Positioning System (GPS) signal in order to maneuver to its target. In some cases, depending on GPS is impractical or impossible, such as: inside buildings, tunnels or other places with no GPS reception or when there are no accurate coordinates of the target or when the UAV has no GPS receiver. There is thus a need for the UAV to navigate without relying on GPS signals (or at least without solely relying thereon) and instead using navigation-enabling information coming from the UAV carrier.

As discussed above, many UAVs are limited in the amount of energy and mission flight time available to them. There is thus a need to elongate the mission time of the individual UAV by relying on energy coming from the UAV carrier.

SHJ623 POW004 ver 2 - 2 - 266248/2 There is thus a need in the art for a new UAV carrier that will be able to transport at least one UAV to its mission area and to support energy transfer from the UAV carrier to the at least one UAV during its mission.

It is to be noted that the terms UAV and drone are used herein interchangeably.

Han, K.S., 2017. Test and Evaluation of an Image-Matching Navigation System for a UAS Operating in a GPS-Denied Environment. Naval Postgraduate School, Monterey, United States, discloses that Without corrective updates from the Global Positioning System, navigational capabilities are degraded significantly when the inertial navigation system becomes the only source of an unmanned aerial vehicle’s movement estimate. Today, unmanned vehicles are easily equipped with a variety of passive sensors, such as video cameras, due to their increasingly lower prices and improvements in sensor SHJ623 POW004 ver 2 - 6 - 266248/2 resolution. The concept of using an image matching technique on an input video camera stream was demonstrated earlier with real flight data using a single low-grade onboard sensor. This technique works by matching the stream of data from the camera with a pre- stored depository of geo-referenced reference images to estimate the current attitude and position of an unmanned aerial vehicle (UAV). Preliminary results indicated that unfiltered position estimates can be accurate to the order of roughly 100 meters when flying at two kilometers above the surface and unfiltered orientation estimates are accurate to within a few degrees. This thesis examines developed algorithms on a suite of video data, seeking to reduce the errors in estimating attitude and position of a UAV. The data sets collected at King City and Camp Roberts, California, are also studied to discover the effect of altitude, terrain pattern, elevation map, light conditions, age of reference data and other parameters on estimation. This thesis concludes that in the absence of other sources of navigational information, imagery from a camera is a viable option to provide positional information to a UAV.

Conte, G. and Doherty, P., 2008, March. An integrated UAV navigation system based on aerial image matching. In Aerospace Conference, 2008 IEEE (pp. 1-10). IEEE, discloses exploring the possibility of using geo-referenced satellite or aerial images to augment an Unmanned Aerial Vehicle (UAV) navigation system in case of GPS failure.

A vision-based navigation system which combines inertial sensors, visual odometer and registration of a UAV on-board video to a given geo-referenced aerial image has been developed and tested on real flight-test data.

In other cases, UAV 120 can be transported to the mission area by a transport vehicle. For example, a truck may be loaded with UAV 120 at a central storage location and driven to the vicinity of the mission area 220. There the UAV 120 may be unloaded from the truck, activate its motors and fly to start fulfilling its missions in the nearby mission area 220.

In yet other cases, UAV carrier 110 can be used to carry and transport the UAV 120 to the vicinity of the mission area 220. It is to be noted, that UAV 120 is not necessarily carried to the mission area 220 by UAV carrier 110.

A non-limiting example, for such a mission may be a disaster relief mission, wherein the mission area 220 is the area hit by the disaster (e.g. an earthquake, a fire, a flood, etc.). UAV 120 can be utilized to bring information or to perform other tasks in the mission area 220, without risking human operators. The UAV 120 may be used in this example to fly to specific UAV targets within the mission area 220 and perform various missions, such as taking video footage of specific objects within mission area 220.

UAV 120 can be fully autonomous in fulfilling its missions, it can be a remotely piloted UAV 120, controlled by human controllers from afar or UAV 120 can have partial SHJ623 POW004 ver 2 - 17 - 266248/2 autonomous capabilities, requiring human intervention in some aspects of its mission. In our example, the navigation of the UAV 120 to its targets might be made autonomously, based on image analysis performed by the UAV 120 or the navigation to the target might be made by a human controller, controlling UAV 120 from a distant location.

In some cases, UAV carrier 110 can be an unmanned vehicle, such as a UAV. In other cases, the UAV carrier 110 is an aerial vehicle. In these cases, the UAV carrier 110 can be flying or hoovering above a mission area 220 as the UAV 120 is fulfilling its missions. In addition, UAV carrier 110 can be fully autonomous. UAV carrier 110 can be remotely piloted, controlled by a human controller from afar or UAV carrier 110 can have partial autonomous capabilities, requiring human intervention in some aspects of its mission.

UAV carrier 110 can comprise one or more cameras 210. In some cases, each camera 210 can be connected to the UAV carrier's 110 body on an outer end of an interface arm extending outwards from the UAV carrier's 110 body. In other cases, cameras 210 can be connected on the outer part of the UAV carrier's 110 body itself. It yet some other cases, cameras 210 can be installed inside an internal part of the UAV carrier's 110 body wherein windows are located on the UAV carrier's 110 body in a way that enables cameras 210 to capture images from outside the UAV carrier 110. Cameras 210 can be installed in a way that they can capture images or video footage of mission area 220.

UAV 120 can rely on GPS signal in order to maneuver to its targets within the mission area 220, but in some cases, depending on GPS is impractical or impossible, such as: inside buildings, tunnels or other places with no GPS reception or when there are no accurate coordinates of the target or when the UAV 120 has no GPS receiver. In these cases, the UAV 120 can navigate to the target by relying on target identification information coming from the UAV carrier 110. This will enable the UAV 120 to reach its target without relying on an internal GPS receiver.

In some cases, the target identification information is a GPS signal. In these cases, the UAV 120 can analyze the GPS signal sent from the UAV carrier 110 in order to navigate to its target within the mission area 220 without the need for an internal GPS receiver.

SHJ623 POW004 ver 2 - 18 - 266248/2 In other cases, the target identification information are images or video footage of the mission area 220. In other cases, the target identification information is based on the images or video footage of the mission area 220 and can be a combination of one or more of: encoding of the images or video footage, vector information based on the images or video footage, outline of the contour of objects in the images or the video footage or any other information that is based on the images or video footage and can be used by the UAV 120 to identify the location and navigate to its targets. In these cases, the images or video footage may include a UAV target marking, marking a geographical location of a target for at least one UAV 120. The target identification information can be transmitted to the at least one UAV 120. The at least one UAV 120 can operate an internal camera to take one or more images of a sub portion of the mission area 230. The sub portion of the mission area 230 may be the area of mission area 220 where the target is located. The at least one UAV 120 can than navigate to its target by analyzing the target identification information and the one or more images of a sub portion of the mission area 230 to determine a spatial disposition from its respective targets. The analysis may be done for example by image analysis, comparing the target identification information and the images captured by the UAV 120. The at least one UAV 120 can than operate its motors to direct itself to its respective targets, based on the results of the analysis.

In the non-limiting illustrated example in Fig. 1 which continues our previous example, of a disaster relief mission, the UAV carrier 110 can be flying above the mission area 220. The UAV carrier can utilize its camera 210 to take images of the mission area.

The UAV carrier 110 can mark a specific target, for example: a window of a damaged building that was damaged in the disaster. A UAV 120 may be hovering above the mission area 220. The UAV 120 can have a mission to take video footage through the window. The video footage can be relayed to a disaster response headquarters and used to decide if and what kind of human assistance is required at the damaged building. In our example the UAV 120 cannot rely on an internal GPS to navigate to the window. The UAV 120 receives marked images or target identification information that is based on the images, for example: a contour of an object in the mission area 220, from the UAV carrier 110 and uses its own camera to take image of a sub portion of the mission area 230. The UAV 120 analyses the marked images and the images it has taken in order to determine SHJ623 POW004 ver 2 - 19 - 266248/2 the spatial disposition of the UAV 120 with respect to the window. The UAV 120 than activates its motors to maneuver itself to the windows and fulfill its mission.

In some cases, the target of a given UAV 120 may change during the mission, for various reasons. For example: a moving target, new information, more accurate target information. In these cases, the UAV carrier 110 may send updated target identification information, relaying the new geolocation of the target of the given UAV 120 to the given UAV 120. The given UAV 120 may than operate its internal camera to capture one or more images of an additional sub portion of the mission area 230. The given UAV 120 can than navigate to its new target by analyzing the additional target identification information and the one or more images of the additional sub portion of the mission area 230 to determine a spatial disposition from its current location to the respective new targets. The given UAV 120 can than operate its motors to direct itself to its respective new targets, based on the results of the analysis.

Continuing our previous example, the UAV's 120 target may change to another window of the same damaged building, for example: to get a better view of the inside of the damaged building. The UAV carrier 110 can than send UAV 120 updated images of the building, with the other window marked as a target. The UAV 120 can than capture additional pictures of the damaged building, and by analyzing them using image analysis, determine a spatial disposition to the other window, navigate to the other window and complete its mission.

In addition, the target identification information may include more than one target and an order of execution for the UAV 120 for fulfilling his missions within these targets.

For example, continuing our previous examples, the target identification information may be an image of the damaged building with markings of a number of windows through which the UAV 120 needs to take footage of the inside of the building. The target identification information will include an order of execution for the UAV 120 to start from a certain window, complete its task and then move to the next window and so on.

It is noted that in some cases the target identification can come from sources other than then camera 210 of the UAV carrier 110. For example, the target identification information can be aerial photographs of the mission area 220 obtained from satellites or other sources. In addition, the target identification information can be obtained in a SHJ623 POW004 ver 2 - 20 - 266248/2 preliminary stage and not during the mission. For example, aerial photographs of the mission area 220 that were pre-loaded to the UAV carrier 110 before the start of the mission.

Turning to Fig. 2. Fig 2 is a schematic illustration of at least one UAV maneuvering while wired to a UAV carrier, in accordance with the presently disclosed subject matter.

According to the presently disclosed subject matter, environment 300, includes a UAV carrier 110. UAV carrier 110 might be any vehicle. UAV carrier 110 might be a wheeled vehicle (e.g. a car, a truck, etc.), a tracked vehicle (e.g. a tractor, an armored tracked vehicle, a tank, etc.), a watercraft (e.g. a boat, a hovercraft, a submarine, etc.) or an aerial vehicle (e.g. a plane, a helicopter, a balloon, etc.) or any other type of vehicle.

Environment 300 further includes at least one UAV 120. UAV 120 may be a fixed-wing air vehicle, a vertical take-off and landing air vehicle, an helicopter, a quadcopter, a drone or any other type of unmanned air vehicle. UAV 120 is commonly used nowadays to take part or to accomplish various missions or tasks that in the past required manned aircrafts. UAV carrier 110 may carry and transport at least one UAV 120 to a location where its mission is to be fulfilled. When reaching the vicinity of the location of its mission, UAV 120 may be released from UAV carrier 110 to fly to its mission utilizing its own energy. It is to be noted, that UAV 120 is not necessarily carried by UAV carrier 110 to the location of its mission and may alternatively be flying to the location of its mission from a central storage location, by utilizing its own energy.

As discussed above, many UAVs are limited in the amount of energy and the mission flight time available to them. There is thus a need to elongate the mission time of the individual UAV by relying on energy coming from the UAV carrier. This can be achieved by one or more wire 310 that connects UAV 120 to the UAV carrier 110 during the mission. Wire 310 may transmit data between UAV 120 and UAV carrier 110, thereby saving the need for UAV 120 to have a wireless communication module. This can make UAV 120 lighter and more energy efficient than another UAV 120 that is not wired to UAV carrier 110 and does require a wireless communication module in order to receive and transmit data needed for its mission.

SHJ623 POW004 ver 2 - 21 - 266248/2 Additionally, or alternatively, wire 310 may be utilized to transfer electrical current from the UAV carrier to the UAV 120, thereby enabling the UAV 120 to enlengthen its mission time, relaying on energy coming from the UAV carrier 110. It is to be noted that wire 310 may be used to transfer both data and electrical current between UAV carrier 110 and the UAV 120.

A non-limiting example for such a mission may be a disaster relief mission, wherein an area is hit by a disaster (e.g. an earthquake, a fire, a flood, etc.) and the UAV 120 is utilized to bring information or to perform other tasks in the disaster hit area, without risking human operators. The UAV 120 may be used in this example to fly to specific objectives while connected to the UAV carrier with respective wires 310. Each wire 310 can transfer data between the UAV 120 and the UAV carrier. The wire 310 can optionally additionally, or alternatively, transfer electrical current from the UAV carrier 110 to the UAV 120.

Attention is drawn to Fig. 3, a block diagram schematically illustrating one example of a UAV carrier, in accordance with the presently disclosed subject matter.

According to certain examples of the presently disclosed subject matter, UAV carrier 110 may be any vehicle that can carry and transport at least one UAV 120.

SHJ623 POW004 ver 2 - 22 - 266248/2 UAV carrier 110 can further comprise, or be otherwise associated with, a data repository 415 (e.g. a database, a storage system, a memory including Read Only Memory – ROM, Random Access Memory – RAM, or any other type of memory, etc.) configured to store data, including inter alia navigational data, missions and targets information related to at least one UAV 120, wired manure information, etc. Data repository 415 can be further configured to enable retrieval and/or update and/or deletion of the stored data.

It is to be noted that in some cases, data repository 415 can be distributed, while the UAV carrier 110 has access to the information stored thereon, e.g. via a wireless network to which UAV carrier 110 is able to connect to.

UAV carrier 110 further comprises a controller 410. Controller 410 can be one or more processing units (e.g. central processing units), microprocessors, microcontrollers or any other computing devices or modules, including multiple and/or parallel and/or distributed processing units, which are adapted to independently or cooperatively process data for controlling relevant resources of the UAV carrier 110 and for enabling operations related to resources of the UAV carrier 110.

The controller 410 can comprise one or more of the following modules: target management module 435 and wired maneuver management module 440.

The wired maneuver management module 440 can be configured to perform a wired maneuvering process, as further detailed herein, inter alia with respect to Fig. 5.

According to certain examples of the presently disclosed subject matter, UAV 120 can comprise motors 460, capable of generating a lift for UAV 120. UAV 120 may additionally comprise of rotors 465, controlled by said motors 460 to rotate and provide said lift. In other cases, motors 460 are jet motors and can directly create lift for UAV 120. UAV 120 may be a fixed-wing air vehicle, a vertical take-off and landing air vehicle, a helicopter, a quadcopter, a drone or any other type of unmanned air vehicle. UAV 120 may be fully autonomous in fulfilling its missions, it may be remotely piloted, or it may have partial autonomous capabilities, requiring human intervention in some aspects of its mission.

SHJ623 POW004 ver 2 - 23 - 266248/2 UAV 120 can further comprise one or more cameras 475, each capable of capturing images of a sub portion of a mission area 230.

UAV 120 can further comprise, or be otherwise associated with, a data repository 480 (e.g. a database, a storage system, a memory including Read Only Memory – ROM, Random Access Memory – RAM, or any other type of memory, etc.) configured to store data, including inter alia navigational data, missions and targets information, wired manure information, etc. Data repository 480 can be further configured to enable retrieval and/or update and/or deletion of the stored data. It is to be noted that in some cases, data repository 480 can be distributed, while the UAV 120 has access to the information stored thereon, e.g. via a wireless network to which UAV 120 is able to connect to.

UAV 120 further comprises a controller 445. Controller 445 can be one or more processing units (e.g. central processing units), microprocessors, microcontrollers or any other computing devices or modules, including multiple and/or parallel and/or distributed processing units, which are adapted to independently or cooperatively process data for controlling relevant resources of the UAV 120 and for enabling operations related to resources of the UAV 120.

The controller 445 can comprise one or more of the following modules: image navigation management module 495 and wired maneuver management module 497.

According to some examples of the presently disclosed subject matter, image navigation management module 495 can be configured to perform a target management and image navigation process, as further detailed herein, inter alia with respect to Fig. 4.

The wired maneuver management module 497 can be configured to perform a wired maneuvering process, as further detailed herein, inter alia with respect to Fig. 5.

Fig. 4 is a flowchart illustrating one example of a sequence of operations carried out for navigating utilizing information from a UAV carrier, in accordance with the presently disclosed subject matter.

According to certain examples of the presently disclosed subject matter, UAV carrier 110 and UAV 120 can be configured to perform a target management and image navigation process 600, e.g. by UAV carrier 110 utilizing the target management module 435 and by UAV 120 utilizing the image navigation management module 495.

SHJ623 POW004 ver 2 - 24 - 266248/2 As detailed above, UAV 120 may rely on GPS signal in order to maneuver to its targets within the mission area 220 but in some cases depending on GPS is impractical or impossible. These cases may be: inside buildings, tunnels or other places with no GPS reception or when there are no accurate coordinates of the target or when the UAV 120 has no GPS receiver. In these cases, the UAV 120 can navigate to the target by relying on target identification information coming from the UAV carrier 110. This will enable the UAV 120 to reach its target without relying on an internal GPS receiver or in some cases, without solely relying on the internal GPS. In these cases, navigation can be achieved be a combination of relying on the internal GPS and of relying on the target identification information. It is to be noted that this will allow the UAV 120 to be lighter, as it does not require a GPS receiver. This will allow to UAV 120 to be more energy efficient and to have longer mission flight time for the same amount of available energy.

For this purpose, controller 410 of UAV carrier 110 can be configured to operate the one or more camera 210 to capture at least one image of a mission area 220 and identify, on the image, for the at least one UAV 120, a respective UAV target, being indicative of a destination of the respective UAV 120 (block 610). In some cases, the identification and marking of respective UAV targets on the images is done automatically by controller 410. In other cases, a human operator is involved in the process of identifying and marking respective UAV targets on the images.

In some cases, camera 210 has a wider angle of the mission area than an angle available to camera 475 of the UAV 120, as UAV carrier 110 can hover higher over the mission area 220 than the altitude of UAV 120 as it flies down to fulfill its mission within mission area 220. It is to be noted that in these cases, camera 475 will be able to capture a sub portion of the mission area 230 which is a smaller area, included within the boundaries of mission area 220. In some cases, camera 210 can have larger lenses, better focus, better range or other photographic parameters that are better than those of camera 475.

In the non-limiting illustrated example in Fig. 1, UAV carrier 110 can be hovering high above the disaster area (e.g. higher than the at least one UAV 120). Camera 210 is connected to the body of UAV carrier 110 having a wide angle of mission area 220. UAV SHJ623 POW004 ver 2 - 25 - 266248/2 carrier captures an image of a damaged building within mission area 220 and identify on the image a specific window which if the target for UAV 120.

After capturing at least one image of the mission area, controller 410 of UAV carrier 110 can be configured to send to the at least one UAV 120, respective target identification information, based on the image and on the respective UAV target (block 620).

In some cases, the target identification information may be the image itself along with the marking thereon, and/or an encoding of the image. For example, UAV carrier 110 may analyze the image, identify the contour of the target area and send UAV 120 just the contour and a marking of the target. In these cases, the communication between the UAV carrier 110 and UAV 120 requires less bandwidth than transmitting the entire image.

Controller 445 of UAV 120 can be further configured to receive the respective target identification information (block 630).

It is to be noted, that the sending and receiving of target identification information in blocks 620 and 630 above, can be continues. In some cases, this is due to changes in the missions of UAV 120. For example: a moving target, new information, more accurate target information. The change in the mission may arise from information received from UAV 120.

After receiving the respective target identification information, controller 445 of UAV 120 can be further configured to operate the one or more cameras 475 to capture navigation images of a sub portion of the mission area 230 (block 640).

Controller 445 of UAV 120 can be further configured to analyze the respective target identification information and the navigation images to determine a spatial disposition of the given UAV 120 with respect to the respective UAV target (block 650).

Based on the spatial disposition of the given UAV 120 with respect to the respective UAV target, controller 445 of UAV 120 can be configured to operate one or more of the motors 460 to direct the UAV 120 to the respective UAV target based on the results of the analysis (block 660).

In some cases, UAV 120 will be assigned one or more targets.

SHJ623 POW004 ver 2 - 26 - 266248/2 Continuing the non-limiting illustrated example in Fig. 1, at least one UAV 120 may be assigned the task of taking video footage of the window of the damaged house within mission area 220.

It is to be noted that, with reference to Fig. 4, some of the blocks can be integrated into a consolidated block or can be broken down to a few blocks and/or other blocks may be added. Furthermore, in some cases, the blocks can be performed in a different order than described herein (for example, block 640 can be performed before block 610, etc.).

It is to be further noted that some of the blocks are optional. It should be also noted that whilst the flow diagram is described also with reference to the system elements that realizes them, this is by no means binding, and the blocks can be performed by elements other than those described herein.

Fig. 5 a flowchart illustrating one example of a sequence of operations carried out for preforming maneuvers while wired, in accordance with the presently disclosed subject matter.

According to certain examples of the presently disclosed subject matter, UAV carrier 110 and UAV 120 can be configured to perform a wired maneuvering process 700, e.g. by UAV carrier 110 utilizing the wired maneuver management module 440 and by UAV 120 utilizing the wired maneuver management module 497.

As detailed above, many UAVs are limited in the amount of energy and the mission flight time available to them. In order to elongate the mission time of the individual UAV 120 a wire 310 is used to enable UAV 120 to rely on energy and data coming from the UAV carrier 110.

UAV 120 is configured to take into consideration the position and placement in space of the wire 310 connecting it to the UAV carrier 110 in order for UAV 120 to preform maneuvers without entangling wire 310. It is to be noted, that UAV carrier 110 can also take into consideration the positions and placement in space of the one or more wires 310, connecting the at least one UAV 120 to the UAV carrier 110, in order for UAV carrier 110 to preform its maneuvers without entangling the one or more wires 310.

For this purpose, UAV 120 can be configured to perform maneuvers irrespective of maneuvers of the UAV carrier 110 during performance of a mission (block 710).

SHJ623 POW004 ver 2 - 27 - 266248/2 Continuing the non-limiting illustrated example in Fig. 2, UAV 120 is flying to its targets while connected to the UAV carrier with respective wires 310. When maneuvering, UAV 120 takes into consideration the position and placement in space of their respective wire 310, so that the wires 310 will not get entangled with one another.

In this example, UAV carrier 110 will also take into consideration the position and placement in space of all wires 310 connecting UAV 120 to it, when maneuvering itself.

Wire 310 may transmit data between UAV 120 and UAV carrier 110, thereby saving the need for UAV 120 to have a wireless communication module. This can make UAV 120 lighter and more energy efficient than another UAV 120 that is not wired to UAV carrier 110 and does require a wireless communication module in order to receive and transmit data needed for its mission.

In some cases, wire 310 may be utilized to transfer electrical current from the power supply 425 of UAV carrier 110 to the respective UAV 120, thereby enabling the UAV 120 to enlengthen its mission time, relaying on the energy coming from power supply 425. In these cases, the electrical current received by UAV 120 through wire 310 may be utilized to charge battery 485.

In other cases, the electrical current received by UAV 120 through wire 310 may be utilized to power the UAV 120 directly. In these cases, UAV 120 may not need battery 485, thus making UAV 120 lighter and more energy efficient than another UAV 120 that is not wired to UAV carrier 110 and does require a battery 485.

It is to be noted that in some cases, a given UAV 120 can be connected to UAV carrier 110 with one or more wires 310. In these cases, each wire 310 can transmit electrical current, digital data or both between the UAV carrier 110 and the given UAV 120.

For this purpose, UAV 120 can be configured to receive at least one of an electrical current or digital data from the UAV carrier 110 through the respective wires 310, during performance of the mission (block 720).

In the non-limiting illustrated example in Fig. 2, a given UAV 120 receives both data and electrical current through the wire 310, connecting the given UAV 120 to the UAV carrier 110, so that the given UAV 120 does not require a wireless communication SHJ623 POW004 ver 2 - 28 - 266248/2 module and does not require a battery 485, thus making UAV 120 lighter than a UAV 120 that does require those modules.

It is to be noted that, with reference to Fig. 5, some of the blocks can be integrated into a consolidated block or can be broken down to a few blocks and/or other blocks may be added. Furthermore, in some cases, the blocks can be performed in a different order than described herein (for example, block 720 can be performed before block 710). It is to be further noted that some of the blocks are optional. It should be also noted that whilst the flow diagram is described also with reference to the system elements that realizes them, this is by no means binding, and the blocks can be performed by elements other than those described herein.
