DELIVERY SYSTEM FIELD OF THE INVENTION

[0001] The present invention relates to a delivery system, and in particular to a delivery system using an Unmanned Aerial Vehicle ("UAV") to deliver goods to a receptacle.

BACKGROUND OF THE INVENTION

[0002] Drones or UAVs are being used for civil applications now, such as to film sports events or movies, and in agriculture. Attempts have also been made to use drones to deliver specific items, such as text books within a city. However, these attempts have been prevented due to the method being dissatisfactory and not in accordance with local laws. To deliver goods the Global Positioning System ("GPS") technology may be used to direct the UAV from the warehouse to a particular location. The person would need to know to go to the location at a particular time, and when they can see the UAV they move towards it to receive the goods, dropped into their hands.

[0003] There are significant difficulties and disadvantages with the existing drone delivery system attempts. At present the person must be home to collect the goods, or the goods may drop to the ground and be damaged or risk injury to children or animals in the vicinity. If articles are simply deposited at a location, this is insecure and the item may be taken by a person before the owner returns to collect the goods. Evidently there are many issues to try to safely and securely deliver the goods to the correct recipient, in an efficient manner which is cost effective to the operator.

[0004] GPS has limitations in that the accuracy is only within around 10 metres, not accurate enough for delivery to a predetermined location or without assistance from a person. Therefore the person must be at the location when the delivery is to take place, and this is generally inconvenient. Existing systems are simple, inaccurate and require interaction from the person; they must be home to take delivery of the goods or these will simply be dropped on the ground. It would be extremely useful for goods to be delivered to a very specific location, verify the correct location and deliver the goods to be kept securely for the owner until they return home.

[0005] The inventor has developed a significant improvement on the prior art whereby goods can be delivered precisely by a UAV to a secure container without the need for assistance by the recipient. In this way a person can have goods delivered safely and securely, while they are away from a location, say at work, for retrieval later. The applications of the invention, such as for on-line ordering of goods are immense. Imagine ordering a shirt to wear out in the evening at lunchtime or perhaps even on the train on the way home and it being delivered securely before you arrive home, ready to wear. Courier services in large cities with warehousing nearby can deliver quickly, but only if there is a person home to receive the goods and only within normal working hours. Use of UAVs and the subject invention extends the hours in which deliveries can be made, and removes the need for the person themselves to be home to receive the goods-a very significant advance over the prior art.

[0006] The following describes a non-limiting example of the invention being used with reference to use with a UAV or "drone". Clearly other similar unmanned or radio controlled aerial vehicles could be used instead. The invention relates to the delivery system, rather than the particular vehicle to which it is applied. Further, the current locating system, the GPS, is referred to throughout however, it is not intended that the locating system be limited to GPS should alternative systems be developed to provide the general positioning data.

[0007] For clarity, any prior art referred to herein, does not constitute an admission that the prior art forms part of the common general knowledge, in Australia or elsewhere.

[0008] It is an object of the present invention to provide a delivery system that at least ameliorates one or more of the aforementioned problems of the prior art. DISCLOSURE OF THE INVENTION

[0009] Accordingly, the present invention provides a delivery system for use with an unmanned aerial vehicle ("UAV") to deliver goods to a location, the delivery system including: a first part mounted to the UAV, including a carrier means for carrying the goods so they are carried with the UAV and a sensor means, in communication with the controls of the UAV; and a second part at the delivery location, including a receptacle for receiving the goods, at the delivery location, the receptacle including an opening for receipt of the goods, and locating means, associated with the receptacle, to provide location data of the opening of the receptacle to the sensor, wherein, the UAV can be directed to deliver goods carried in the carrier means to near the delivery location and on the sensor detecting the location means, communicates with the controls of the UAV to move the UAV to be substantially aligned with the opening of the receptacle for release of the goods therein.

[0010] The UAV may be any suitable drone or similar. The UAV may form part of the inventive product sold or may be separate and the inventive apparatus supplied separately. The UAV may be a 3DR IRIS (Trade mark) drone refer http://store.3drobotics.com/products/IRIS or based thereon. Any suitable form of UAV may be used to deliver the goods. Preferably, the UAV is a small, lightweight unmanned aerial vehicle of a known form which can be readily manoeuvred. Preferably, the UAV includes a control unit to control the movement of the UAV and a power supply to provide power to the UAV, including the controls. The control unit includes computer circuits and software to control the UAV as would be understood by the person skilled in the art. Preferably, the power supply and control unit of the UAV are protected by a housing. A mobile or wireless receiver and transmitter arrangement is preferably included so that signals can be sent and received by the UAV. The signal may be through the mobile phone network. [0011] Preferably, the UAV includes one or more propeller. Preferably, the UAV includes one or more blade units and it is the blade units that provide the propulsion and lift of the UAV. The UAV may, in an alternative form of the invention, be a small helicopter with a blades in a similar arrangement to known full size helicopters, used for transportation. Preferably, there are four blade units each including a propeller and a motor on an arm, controlled by the control unit and powered by the power unit of the UAV to provide propulsion and control of the height and direction of movement of the UAV. Preferably, each of the four blade units is controlled independently by the control unit to provide fine control of the height, movement and position of the UAV. In an alternative form of UAV, another form of propulsion or lift may be used instead and still fall within the remit of the invention.

[0012] Communication to the control unit enables the UAV to be controlled so as to be moved to a particular location, powered by the power supply. The controlling may include speed, height, and movement backwards, forwards, up, down and left and right. The communication may include instructions provided before commencing the delivery. Preferably, the communication is through a wireless network. The communication may be wireless communication through the mobile phone network. Preferably, the UAV includes a GPS. Preferably, the GPS unit included is mounted so as not to interfere with other components of the UAV or device. The GPS unit may be mounted on a stick or pole so as to project, somewhat from the body of the UAV. Preferably, predetermined coordinates can be communicated to the control unit and the UAV directed to go to a particular GPS location at the commencement of the delivery. The GPS may include software to look up the GPS coordinates of a particular delivery location. The GPS of the UAV may communicate directly with the GPS satellite system to determine the delivery location or initial data may be communicated to the control unit so that the UAV can move to the delivery location. Preferably, the UAV moves without further significant input or data from the start point to the delivery location controlled by the control unit to travel to the GPS coordinates. Preferably, the UAV moves from a warehouse to a delivery location completed untouched by a person. Most preferably, once the control instruction is input the UAV travels unaided from the warehouse to the point of delivery and following delivery returns to the warehouse. Multiple deliveries may also be possible on a single trip by the UAV, and in this case multiple location data is entered.

[0013] The goods may be any goods it may be desired to deliver to a location that can be comfortably carried by the UAV, and suitable for delivery in this manner. Most preferably, the goods are contained within a box. The goods may be put in a box prior to delivery or the goods may already be contained within a box. Preferably, the goods are lightweight goods, not prone to damage. The goods may be clothing. The goods may be consumables. The goods may be goods purchased through use of a credit card or account.

[0014] The delivery location may be any suitable location for delivery of goods. Preferably, the delivery location is an address provided by the person who orders the goods. The address may be a home address, work address or other address for receipt of the goods. The delivery location may be within a city boundary. The distance from the warehouse for delivery of the goods will depend on the length of journey that can comfortably be travelled by the UAV. The distance may be within a city or may be between cities or areas, wherever the UAV can be directed to deliver the goods. Preferably, the location can be given as GPS coordinates.

[0015] The first part denotes the parts of the system associated with the UAV. There may be a plurality of parts included in the first part. The first part may be mounted at different locations about the UAV. It is not intended that the first part be limited to a discrete item including both the carrier means and the sensor, eg these features may be mounted at different places on the UAV. In other forms of the invention the first part and the UAV are formed together, for example the carrier means may be the carrying of the goods within the body of the UAV. Preferably, however, the first part is carried beneath the UAV. The first part may take any suitable form. The first part, second part and UAV may be supplied together. Any of the first part, second part and UAV may be supplied separate from one another. The first part may be removably mounted to the underside of the UAV. The first part may be manufactured integrally with the UAV. The mounting of the first part may be the removable attachment of the carrier means and sensor to the UAV. The mounting may be by means of bolts or other strong and secure suitable fittings. The mounting may be by welding or a more permanent mounting to the UAV.

[0016] The carrier means may take any suitable form. Preferably, the carrier means carries the goods below the UAV. If the UAV contained a body then the goods may be carried within the body instead. Preferably, the carrier means carries the goods by the goods being firmly held between two jaws or similar. The carrier means may act like a vice to hold the goods therebetween. Preferably, the carrier means is firmly and securely held in the carrier means so that the goods are transported from a first location to a second location. Preferably, the carrier means is adapted to securely carry the goods so as not to be released until it is desired to do so. The release may be by means of control from the controls of the UAV.

[0017] The carrier means preferably has a top and two side portions and the two side portions are adapted to firmly hold the goods between them. In one form of the invention the goods are contained in a box of a standard size and the carrier means are adapted to receive and firmly hold the box. In another form of the invention the carrier means may press against the sides of the goods or box to hold the goods in place. Preferably, the carrier means includes two parts that can be caused to press against the sides of the goods, when carried in a box. Preferably, two adjustable parts are included which can be adjusted in the horizontal plane such that the hold on the goods can be loosened and tightened and the distance between the two parts shortened and lengthened. In this way the goods can be surrounded, and as the two parts move together grip and hold the goods ready for delivery. Similarly, release of the goods can be achieved by reversal of the process eg release of the pressure. Preferably, the control unit controls the pressure applied by the two parts to the goods. Preferably, the goods are placed between the two parts and the two parts caused to move together to hold the goods therebetween. The firm hold may continue for the transportation only to be released on delivery of the goods. The release may only occur when the sensor senses that there has been alignment with the receptacle by use of the location means. The carrier means may include an adjustable part. The release may be any deployment whereby the goods enter the receptacle. The carrier means may be adapted to carry a box of variable width. The carrier means may include a part adaptable to firmly hold a box of any suitable width. Preferably, the hold of the carrier means is controlled by the control unit of the UAV. Alternatively, a separate control may be included together with a separate power supply, in another form of the invention.

[0018] The sensor means may take any suitable form to locate opening of the receptacle. Preferably, the sensor includes a part that is positioned below the UAV to facilitate "seeing" the locating means. Preferably, the sensor means is capable of capturing an image. Preferably, the sensor means includes a camera. Preferably, the sensor means can detect the location means and based on the "picture" received calculate the movement required to bring the UAV to the appropriate height and position for delivery of the goods. Known object or pattern identification technology may be used to recognise particular features. The sensor means of the invention may include image recognition software. The particular features may be an arrangement to form a shape, such as a square or other symbol or pattern, recognisable by the sensor and associated software.

[0019] Preferably, the sensor means is in communication with the control unit such that interpretation of the sensed data can cause control of the UAV. The UAV may, in this way be moved to the precise delivery location eg the opening of the receptacle. For example, on recognition of the receptacle by the sensor the UAV is controlled to move so as to align the "picture" of the receptacle to be centred within the view of the sensor. Further, as the receptacle is sensed this provides data as to how high the UAV is above the receptacle and so adjustments can also be made to lower the UAV, to be at a suitable height for delivery. [0020] Preferably, the second part is installed at the delivery location in a manner considered convenient by the consumer. The second part may be installed all together or separately. The second part generally defines the parts of the system associated with the delivery location. There may be a plurality of parts at the delivery location, loosely defined as the second part. Preferably, the receptacle and the locating means, of the second part, are installed together. Preferably, the receptacle and locating means are installed together at the precise location where delivery of the goods is desired.

[0021] Preferably, the receptacle is suitable for receipt of the goods therein. The receptacle may take any suitable form. The receptacle may be an opening to allow goods to be received therethrough. In this form of the invention the receptacle may be adapted to deliver goods to a suitable location within an abode, whereby further security or containment is not required. Preferably, the receptacle includes a funnel part to assist in guidance of goods into the receptacle and in particular into a secure part. Preferably, the receptacle has been installed at a predetermined height and position. The installation may be a professional installation. Preferably, the receptacle includes a secure part for keeping the goods secure until an authorised person accesses the goods for removal. Preferably, a key and lock system is used to prevent unauthorised access of the goods. Preferably, the receptacle includes a funnel part to guide the goods into a secure part which can only be accessed through use of a lock. The lock may be a conventional lock. The lock may be a mobile phone and cable powered lock developed by the inventor and subject of a separate international patent application PCT/AU2013/000484 in the name of the inventor. A mobile phone or other electronic device may be used to unlock the secure part. The secure part may be in the form of a secure cupboard with a funnel at the top into which the goods can be dropped from above and access is prevented other than through a locked door.

[0022] The receptacle may be made of any suitable strong material including strong plastic or metal, such as stainless steel. The receptacle may be any suitable shape. Preferably, the receptacle has a substantially square opening. Preferably, the opening is configured to be considerably bigger than the goods to be delivered. Where a funnel part is included the size of the opening into the funnel part may be considerably broader than the secure part for securely keeping the goods. Preferably, the opening has two pairs of opposed sides. Preferably, there are four corners to the opening defining a substantially square shape.

[0023] Preferably, the locating means are located about the opening of the receptacle. Preferably, the location means surround the opening of the receptacle. Preferably, the opening of the receptacle includes 4 locating means defining a substantially square shape. In alternative forms of the invention more or less locating means can be included. A plurality of locating means may be included defining an edge or shape. In this form of the invention the sensor means can "see" the substantially square shape when in the general location as directed by the GPS coordinates and based on the position of the square as seen by the sensor and the size the height to descend and the movement side to side can be determined by trigonometry and directions sent to the control unit so that the UAV follows those directions and moves to substantially align with the opening of the receptacle. The aligning may be to any location that enables delivery of the goods to the receptacle. Preferably, the locating means define a shape that can be sensed or seen by the sensor and calculations made to move the UAV to substantially align with the opening of the receptacle for delivery of the goods. The locating means may take any suitable form. The location tags may be points visible by the sensor. The locating means may be location tags chosen from the group: coloured balls, coloured parts on the edge of the receptacle, LEDs, lights or other visual means for detection by the sensor. In another form of the invention, the sensor can detect another form, a non-visual communication of the position and height of the receptacle opening to the UAV.

[0024] Preferably, identity tags are included to identify the particular receptacle. Preferably, the identity of the particular receptacle is verified before delivery. The receptacle may communicate other data, such as specific information on the height or angle of delivery to improve delivery of the goods. The identity tags may be light or other sequences recognisable by the sensor. The identify tags may be LEDs. The LEDs may be programmed to flash to communicate the identity. The LEDs may be used to communication the identity in any suitable manner. Preferably, the identity tags include one or more barcodes. Preferably, one or more barcodes is included on the receptacle. Preferably, one or more edge of the opening of the receptacle includes a barcode. Preferably, the barcode communicates data to the UAV. Preferably, the data includes identification data to verify that the receptacle is the correct receptacle to which the goods are to be delivered. The UAV may be pre-programmed with data against which the barcode data can be matched to check the identity of the receptacle before delivery. Preferably, the barcodes are included on one or more edge of the receptacle. Preferably, the barcodes are provided on all four edges of a square receptacle opening. Preferably, the barcodes provide identification data that can be verified by the sensor before the sensor uses the locating means to direct the UAV to the location of the opening of the receptacle.

[0025] The locating means may be associated with the receptacle in any suitable manner. Preferably, the location means are mounted are the edge of the opening of the receptacle. In other forms of the invention the location means could be mounted elsewhere and communicate information to the UAV to direct it to the opening. It is most preferable for the location means to define the opening of the receptacle in a way that can be sensed by the sensor. Other forms of location means and sensor may be used. For example, the sensor may detect radio signals, lights, laser points, or any suitable indication. Use of the square shape defined by the corners of the receptacle opening is however useful as the calculations for determining where the UAV is relative to the receptacle opening are standard and simple.

[0026] Preferably, the UAV is directed to move to substantially align with the opening before delivery. The alignment may be any suitable position for delivery of the goods. The alignment may be to enable release of the goods under gravity into the receptacle. The UAV may be directed to be substantially within the edges of the opening of the receptacle. The UAV may be directed to be directly above the centre of the receptacle opening, before delivery.

[0027] Preferably, once the UAV is aligned with receptacle opening the control unit is directed to release the goods. The release may be withdrawal of pressure on either side of the goods by the carrier means so that the goods fall down into the receptacle below. The release of the goods may be any suitable release so that the carrier means stops carrying the goods and instead they fall under gravity into the receptacle below. Preferably, the goods are only dropped a very short distance to prevent damage to the goods. The goods may be dropped within the receptacle opening. Where a funnel part is included the goods may be released into the funnel to guide the goods into the secure part. The guidance is gentle so the goods remain undamaged. A means may be included to recognise that there are goods in the receptacle. Preferably, the means is a pressure sensor which can be detected by the sensor of the first part.

[0028] Delivery of the goods is completed once the goods have been received in the receptacle. The UAV may then contain further instructions to direct the UAV to return to the warehouse or to go on to another destination. More than one piece of goods may be delivered at a particular location. Goods to multiple locations may performed in this way by repeating the process.

[0029] Accordingly in a variation the invention also provides a delivery system for use with an unmanned aerial vehicle ("UAV"), to deliver goods to a location, the UAV including a GPS, and control unit, and the delivery system including: a first part mounted to the UAV, including a carrier means for carrying the goods so they are carried with the UAV and a sensor means including a camera, in communication with the controls of the UAV; and a second part at the delivery location, including a receptacle for receiving the goods, at the delivery location, the receptacle including an opening for receipt of the goods into a funnel part and further into a secure part and locating means defining a shape, associated with the receptacle, to provide location data of the opening of the receptacle to the sensor, wherein, the UAV can be directed to deliver goods carried in the carrier means to near the delivery location and on the camera of the sensor detecting the shape defined by the location means, communicates with the controls of the UAV to move the UAV to be substantially aligned with the opening of the receptacle for release of the goods into the funnel part and the secure part to be kept secure until unlocked.

[0030] The UAV and first part may be supplied integrally, and used to deliver goods to the second part at the location.

[0031] Accordingly the invention also relates to a method of using a delivery system for use with a UAV, to deliver goods to a location, the UAV including a GPS and control unit, and the delivering system including a first part mounted to the UAV, including a carrier means for carrying the goods so they are carried with the UAV and a sensor means in communication with the controls of the UAV; and a second part at the delivery location, including a receptacle for receiving the goods, at the delivery location, the receptacle including an opening for receipt of the goods and locating means associated with the receptacle, to provide location data of the opening of the receptacle to the sensor, the method including the following steps: a) Carrying goods in the carrier means; b) Instructing the UAV to travel to a particular GPS coordinate; c) Sensing the location means; d) Calculating the moves required to bring the carrier means to be substantially aligned with the opening of the receptacle; e) Directing the UAV controls to make the calculated moves; f) Releasing of the goods into the opening of the receptacle. [0032] Preferably, there is a further initial step to pick the goods at the warehouse. Alternatively, the goods may be first boxed. The goods may be first put by hand into the carrier means.

[0033] A further verification step may be included. Barcodes may be included on the receptacle to identify the particular receptacle. The sensor may read the barcodes and check against a predetermined barcode to verify that the receptacle is the correct on for delivery.

[0034] Preferably, there is a further step of unlocking the receptacle in order that the goods can be accessed. The unlocking may be by use of a mobile phone. The unlocking may be by use of a mobile phone, and cable to supply the power and instruction.

[0035] A further step of directing the UAV to another location may be included after the goods have been delivered. The another location may be for delivery of further goods. The another location may be to return to a warehouse or the control centre.

[0036] The delivery system of the method may be include delivery system of the invention, as described above in any of its forms or variants.

INDUSTRIAL APPLICABILITY

DETAILED DESCRIPTION OF THE INVENTION INCLUDING A BEST MODE

[0045] Referring to Figures 1 to 6, a preferred embodiment of the invention will be described, where delivery system 1 is used with UAV 10, also known as a "drone" to deliver goods 12 to receptacle 14. Importantly receptacle 14 has been previously installed at a predetermined location by a skilled professional with the height and position complying with the very specific requirements of the system. UAV 10 is of a known form including a power source, GPS and control unit, none of which are illustrated, so that UAV 10 can be moved around, between locations. The GPS is installed on a stalk for convenience of use and so as not to interfere with the other components of the UAV and invention.

[0046] Four blade units, 16, 18, 20 and 22 are included, each including an arm, on which a rotary blade or propeller is mounted on its individual motor; these parts are evident, for example from Figure 5, and are not labelled separately. Rotary blades 16, 18, 10 and 22 are of a known, form, of the known form of drone as would be readily understood by a person skilled in the art. It is the rotary blades of blade units 16, 18, 20 and 22 which provide the movement forward and back, up and down and side to side so that UAV 10 can be directed as required. Each blade unit is controlled individually by the control unit, powered by the power source, of UAV 10 and can also be controlled remotely. UAV 10 is illustrated as an adapted form of the 3DR IRIS (Trade mark) drone refer http://store.3drobotics.com/products/IRIS. The particular brand of UAV or drone can be varied to any suitable UAV, it is the carrier and delivery method that is subject of the invention. However, it is envisaged that a specialised UAV or drone may be provided that is purpose built to include the delivery system and such a UAV or drone certainly falls within the scope of the disclosed invention.

[0047] A GPS is included which enable coordinates to be entered into the control unit so that UAV 10 is taken to a particular GPS location. For example, ordering goods at a particular location may be linked to a GPS coordinate data look-up program and the appropriate GPS coordinate for the delivery address entered in the control unit. On activation UAV 10 will then travel to the GPS coordinates of the location, either with or without human direction depending on the nature of the journey. The difficulty of course is that GPS is only accurate within about 5 to 10 metres or so depending on the location and technology used. It is for this reason that the subject invention includes means to further control UAV 10 on arrival at the GPS location to line up to a precise location where it is desired to deliver goods 12.

[0048] Once UAV 10 arrives at the predetermined GPS location, as recognised by the GPS system, mounted externally, sensor 20 UAV 10 will be directed to be at a suitable height, such as 20 metres high, above the height of receptacle 14 At this height the whole area of the delivery GPS coordinates will be "visible" by sensor 24. Sensor 24 is adapted to sense, locate and identify receptacle 14 by means identification tags on each corner of receptacle 14 and barcodes along each side. UAV 10 will be directed to move close enough to receptacle 14 to read the barcodes and verify that receptacle 14 is correct. A zoom camera can be used to increase the distance that the barcodes can be read. If it is found that the receptacle is not correct UAV 10 is moved back up again to "look" for another receptacle and check the barcodes for verification. Together use of barcodes verify that receptacle 14 is the correct receptacle for delivery and the identification tags assist to align UAV 10 so that the goods can be dropped in and delivered safely and securely. Corner 26, has identification tag 26a, with barcode 27 lying on the edge of receptacle 14 between corner 26 and corner 28. Corner 28 also has identification tag 28a, and barcode 29 lying on the edge of receptacle 14 between corner 28 and corner 30, with identification tag 30a. Similarly, barcode 31 lies between corner 30 and 32, with identification tag 32a and barcode 33 lies on the edge between corner 32 and first corner 26. The data denoted by bars of barcodes 27, 29, 31 and 33 cannot be seen in the illustrations, however these are of the usual form. It is intended that the information is of a sufficient size that the barcodes are readily visible by sensor 24 at the usual flight height, say 20 metres. Software for reading barcodes is well known and is incorporated into sensor 24 and associated computer circuits. Once the verification data of the barcode has been read, secondary information may also be communicated. Generally there is a standard procedure for delivery, common to all receptacles and locations. However, secondary information may be provided for alignment to give a particular angle or height adjustment instruction as was found previously to improve receipt of goods 12, in receptacle 14. The adaptation could also be to avoid an obstacle that impairs approaches or access to receptacle 14 in a particular direction. For example if a tree blocks an approach from one direction this information can be stored to improve subsequent deliveries. The secondary information can be changed over time to adjust and improve delivery to the specific receptacle.

[0049] Barcodes have been around for a long time and are a simple technology for creating a visible, readable number that can be logged or read electronically. Other forms of verifying or identifying the particular receptacle could be used instead.

[0050] Once sensor 24 has verified via at least one of barcodes 27, 29, 31 and 33 that receptacle 14 is the correct receptacle for delivery, the alignment can commence. Sensor 24, at the suitable height is also within visual communication of tags 26a, 28a, 30a, and 32a of corners 26, 28, 30 and 32, respectively. Tags 26a, 28, 30a, and 32a as illustrated are balls which can be seen and recognised by sensor 24 through sensor 24 taking a picture, using known image recognition software. For example, a check shape may be included of a square defined by the tags and once the sensor senses a matching picture controls are adjusted to zoom in closer for delivery.

[0051] Based on the known height and location of the verified receptacle 14 and the picture taken by sensor 24 the location of receptacle 14 relative to the current UAV 10 location can be accurately calculated using standard trigonometry. The required moves of UAV 10 are calculated and communicated via the control unit so that blade units 16, 18, 20 and 22 can be adjusted accordingly by varying their speed. The height and side-to-side movement of UAV is therefore changed to move UAV 10 towards receptacle 14. Other forms of tags could be used, for example, coloured balls, different shaped items, anything that can be "seen" by the sensor and the data can provide sufficient information for UAV 10 to calculate its relative position and be controlled to automatically line up with the opening of receptacle 14. LED or other forms of sensor can also be used. In these forms of tag, the lights can provide the alignment square to enable delivery within the check shape, which leads to receptacle 14.

[0052] During the process sensor 24 is continually scanning to adjust and correct the calculated movements, based on the positions of tags 26a, 28, 30a, and 32a as seen as the picture taken by sensor 24. As illustrated sensor 24 includes a camera that recognises the pre-programmed arrangement of tags, the size of square determining the height of UAV 10 relative to receptacle 14. The position within the viewfinder assists to line up precisely with the opening for delivery. Suitable calculations and controls are then given to instruct the fine movement of UAV 10 to line up with the opening of receptacle 14. Therefore, any necessary correction or adjustment to the calculations as UAV gets closer to the opening of receptacle 14, can be made so that there is an accurate alignment for example the square gets bigger and aligns in the viewfinder. Once a particular view of the square is achieved that will send a signal to UAV 10 that alignment has occurred and goods 12 can be released into the opening.

[0053] Receptacle 14 can be seen to have a receiving part 34 and a secure part 36. Receiving part 34 has a wide opening accessible only from above, which feeds down into secure part 36. Secure part 36 is in the form of a secure cabinet which can only be accessed through locked door 38 and opened through use of handle 40. Opening 42 links receiving part 34 to secure part 36.

[0054] Holder 44 is the part that holds goods 12 by applying pressure across its width. Power for the holding is supplied by the power supply of the UAV as illustrated as there is a common power source. Readily the single power source could be replaced, with individual power sources for the difference aspects. On closing of the circuit on instruction from the control unit the grip of the holder can be released and goods 12 will fall under gravity. Assuming the alignment has occurred goods 12 will be released into receptacle 14 for collection. In other forms of the invention the release may be replaced with alignment to a predetermined position and deployment of the goods in a way not utilising direct gravity.

[0055] In use, GPS will align UAV 10 generally with the location but would not be sufficient to align goods 12 for delivery. Instead, use of sensor 24 reads the barcodes to identify and verify that the receptacle is the correct one for delivery, and then through calculating the tag arrangement sends further controls to control UAV 10. In this way precise alignment sufficient to enable delivery of goods 12 is possible. Goods are delivered, by release of holder 44 so goods pass into receiving part 34. Receiving part 34 is in the form of a funnel to direct goods 12 gently through opening 42 and into secure part 36. Although not shown, a closure may be used to open in response to control of the delivery system and close again after the goods have been safely delivered into secure part 36. It is intended that secure part 36 is secure until the intended recipient of goods 12 returns and can unlock door 38 and gain access. A secure mobile lock may be used to prevent unauthorised access to the cabinet without a suitable cable, powered by the mobile phone. Other security measures can also be used including conventional locks and key pad controlled access. In other forms of the invention the security may be that the delivery is into a secure home, and no further security may be necessary in this form of the invention. [0056] The inventor has though careful development provided a clever and secure means for items to be delivered to a location without the need for the recipient to be present. The security of verifying the receptacle, aligning and then delivering to a secure cabinet is an invention of great benefit. [0057] It will be apparent to a person skilled in the art that changes may be made to the embodiment disclosed herein without departing from the spirit and scope of the invention in its various aspects.
