[0015] FIG. 1A is a block diagram illustrating an unmanned aerial vehicle (UAV) according to an exemplary embodiment. The UAV 106 can include an inertial navigation system and one or more storage units. The autonomous UAV 106 can autonomously navigate aerially using motive assemblies 102. The motive assemblies 102 can be but are not limited to wheels, tracks, rotors, rotors with blades, and propellers. The UAV 106 can include a body 100 and multiple motive assemblies 102. In this non-limiting example, the motive assemblies can be secured to the body on the edges of the UAV 106.

[0016] The body 100 of the UAV 106 can include a storage unit. The storage unit can include a delivery mechanism. For example, the delivery mechanism may be, but is not limited to, a picking unit (not shown) such as electrically operated clamps, claw-type clips, hooks, electromagnets or other types of grasping mechanisms. The UAV 106 can include a controller 108a, and the inertial navigation system can include a GPS receiver 108b, accelerometer 108c and a gyroscope 108d. The UAV 106 can also include a motor 108e. The controller 108a can be programmed to control the operation of the GPS receiver 108b, accelerometer 108c, a gyroscope 108d, motor 108e, and drive assemblies 102 (e.g., via the motor 108e), in response to various inputs including inputs from the GPS receiver 108b, the accelerometer 108c, and the gyroscope 108d. The motor 108e can control the operation of the motive assemblies 102 directly and/or through one or more drive trains (e.g., gear assemblies and/or belts).

[0017] The GPS receiver 108b can be a L-band radio processor capable of solving the navigation equations in order to determine a position of the UAV 106, determine a velocity and precise time (PVT) by processing the signal broadcasted by GPS satellites. The accelerometer 180c and gyroscope 108d can determine the direction, orientation, position, acceleration, velocity, tilt, pitch, yaw, and roll of the UAV 106. In exemplary embodiments, the controller can implement one or more algorithms, such as a Kalman filter, for determining a position of the UAV. [0018] The UAV 106 can be configured to pick up physical objects 104 (e.g. a pill bottle) using the picking unit. The size of the physical objects 104 can be proportionate to the size of the UAV 106. The UAV 106 can pick up and carry the physical object 104 to a

predetermined location. In some embodiments, multiple UAVs can be configured to pick up a portion of a physical object and carry the physical object together, to a pre-determined location. The UAV 106 can receive instructions from a computing system 200 to deliver one or more physical objects stored in the storage unit to a specified delivery location. The computing system 200 will be discussed in further detail with reference to FIG. 2.

[0019] FIG. IB is a block diagram illustrating a UAV 106 that includes a temperature- controlled storage unit in an exemplary embodiment. In one embodiment, the storage unit 112 can include slots 118a-b on either side of the temperature -controlled storage unit. The temperature-controlled storage unit 112 can include a temperature detection sensor 116 and can be configured to store and house one or more physical objects in the interior volume 114. The temperature sensors 116 can be configured to detect the temperature of the interior volume of the storage unit 112 . The detected temperature can be encoded into

communication signals and transmitted to a computing system with which the UAV 106 is communicatively coupled. . A temperature-controlling device 124 located within the UAV 106 is configured to control the temperature of the interior volume 114 and the one or more physical objects being stored in the storage unit. The temperature controlling device 124 can be, but is not limited to, one or more of, on-off controllers, autotune PID controllers, multiloop controllers, safety limit controllers, other types of controllers and temperature switches. As explained further below, the temperature controlling device 124 may be mechanically and/or electrically coupled to, and controls, one or more barriers and/or devices in the UAV by which temperature controlling device 124 is able to control temperature within the interior volume of the UAV. The temperature-controlled storage unit 112 and the UAV 106 can be made of insulated material such as a fuselage made of a closed cell extruded polystyrene foam (an example of which is Styrofoam®) or machinable aerogel. The UAV 106 can also have an aerodynamic body shape which maximizes storage space and insulation capabilities.

[0020] FIG. 1C illustrates an interior view of a temperature-controlled storage unit according to an exemplary embodiment. As mentioned above, the storage unit 112 can include an interior volume 114. The interior volume 114 can include multiple sensors 116. In some embodiments, the interior volume 114 can include at least one temperature controlling device 124. Alternatively, the temperature controlling device 124 can be disposed with respect to the temperature-controlled storage unit 112. The sensors 116 can be temperature sensors configured to detect the temperature of the interior volume 114 of the temperature-controlled storage unit 112. In some embodiments, the sensors 116 can be mechanical temperature sensors such as thermometers, or a bimettalic strip. Alternatively, the sensors 116 can be electrical temperature sensors such as thermistor, thermocouple, resistance thermometer or silicon bandgap temperature sensor. In one embodiment, the temperature controlling device 124 can be configured to communicate with a remote computing system and maintain a specified temperature inside the interior volume 114 of the temperature-controlled storage unit 112 based on the detected temperature determined by the sensor and product attributes determined by the remote computing system . The \detected temperature can be encoded into communication signals which are transmitted to the computing system 200. In one embodiment, the temperature sensor may communicate directly with the computing system 200. In another embodiment, the temperature sensor may provide the detected temperature reading to the temperature controlling device 124 which communicates with the computing system.

[0021] Upon receipt of the detected temperature, the computing system 200 may look up product attributes and determine that the products being stored in the storage unit 112 are not at a desired temperature. The computing system may instruct the temperature-controlling device to raise or lower the temperature of the interior volume 114 and the stored product 119. For example, in one embodiment, after receiving instruction, the temperature controlling device may send a signal that causes a barrier to alter or break to release coolant. In one embodiment, the temperature controlling device 124 can utilize an active coolant and take actions such as moving a barrier to release more coolant into a position within the UAV that allows more cooling to take place in the storage unit 112 . Exemplary active coolants may include, but are not limited to, ammonia, sulfur dioxide, hydrocarbons as well as water and alcohol spritzes. Alternatively, in some embodiments, temperature controlling devices 124 can utilize a passive coolant (e.g., a gel pack, dry ice, ice, combinations thereof, or the like) to adjust temperature within the interior volume. For example, the passive coolant may be stored in slots 118a and 118b in the UAV and the temperature controlling device may send a command to move or alter a barrier between the slots and the interior volume 114 of the storage unit 112 to allow a gel pac, dry ice or similar passive coolant to be exposed and therefore provide more cooling into the storage unit 112. In another embodiment, the temperature -controlling device may initiate an endothermic or exothermic reaction between reactants stored in the storage unit that raises or lowers the temperature in the interior volume 114.

[0022] As mentioned above, the temperature controlling device 124 is configured to regulate the temperature within the interior volume 114. In one embodiment, the temperature controlling device 124 can utilize a first reactive material, a second reactive material, a triggering mechanism, and a barrier. The barrier prevents mixing of the first and second reactive materials prior to a triggering event.

[0023] In an embodiment, a second barrier (a thermal transfer barrier) may separate the reactive material from the storage area. This thermal transfer barrier may be configurable to allow a measured rate of thermal transfer between the reactive material and the storage area. The thermal transfer barrier may be configured by selecting the size of the contact area (aperture/window). The reactive chamber may be composed of a material that serves to both contain the reactive materials as well as being thermally conductive. For example, the chamber may be composed of aluminum, copper or polymer/plastic. The reactive chamber may be configured to fit/slide into the storage container. In one embodiment, the amount of surface area in contact between the reactive chamber and storage chamber can be configured by changing the position of the reactive chamber. For example a tube within a tube that has a slot may turn the tube with the slot to adjust the surface area to be exposed.

[0024] In another embodiment, temperature can be further regulated by implementing more than one reactive chamber. Reactive chambers can be triggered in succession to extend the duration of the reaction or concurrently to provide a greater temperature gradient.

[0025] The triggering event may be a signal and/or instruction received from the computing system 200 by the temperature controlling device 124. The triggering event automatically causes the triggering mechanism to alter or move the barrier to initiate at least partial mixing of the first and second reactive materials to produce a resulting reaction (e.g., an endothermic reaction or an exothermic reaction). The resulting reaction regulates the temperature within the interior volume 114 to maintain the temperature within the interior volume 114 at a desired temperature or temperature range. In one embodiment, the triggering mechanism for initiating the force to activate mixing the reactive materials may be a compressed spring. In an embodiment, the spring may be integrated into the removable reactive chamber and may be compressed during preparation/loading of the storage unit.

[0026] In an embodiment, the temperature controlling device 124 can utilize an endo thermic reaction system configured to produce an endothermic reaction upon mixing of the first and second reactive materials. The endothermic reaction reduces the temperature within the interior volume 114 by absorbing energy. In such embodiments, the first and second reactive materials can be liquids. In one embodiment, the first reactive material can be ammonium nitrate and second reactive material can be water. In one embodiment, the first reactive material for an endothermic reaction system can be selected from sodium chloride, sodium hydroxide, hydrogen chloride, ammonium chloride, potassium chloride, combinations thereof, or the like. In such an embodiment, water can be used as the second reactive material.

[0027] In one embodiment, the chamber or chambers in which the reactions take place may be removable, disposable and/or recyclable so as to allow for the removal of spent reactive material. The reactive material may be loaded and/or extracted as a cartridge for easy handling and environmental safety.

[0028] In an embodiment, the temperature controlling device 124 can utilize an exothermic reaction system configured to produce an exothermic reaction upon mixing of the first and second reactive materials. The exothermic reaction increases the temperature within the interior volume 114 by emitting energy. In such embodiments, the first and second reactive materials can be liquids. In one embodiment, the first reactive material can be calcium chloride and the second reactive materials can be water. In one embodiment, the first reactive material for an exothermic reaction system can be magnesium sulfate. In such an embodiment, water can be used as the second reactive material. In one embodiment, sodium acetate supercooled to a solid can be used by itself without a second reactive material.

[0029] In an embodiment, the temperature controlling device 124 can utilze a mechanical triggering mechanism to adjust the temperature inside the storage unit 112. In one embodiment, the mechanical triggering mechanism can be configured to move or break the barrier in response receiving an instruction from the computing system 200. Movement of the barrier, or breaking of the barrier, allows the first and second reactive materials to mix and generates the resulting reaction. In one embodiment, the first and second reactive materials can be kept together as a solid or liquid and a mechanical force delivered to the reactive materials can set the reaction in motion. For example, the mechanical triggering mechanism can be configured to generate a mechanical force to at least one of the first and second reactive materials in response receiving an instruction from the computing system 200 via the temperature controlling device 124. The mechanical force initiates mixing the first and second reactive materials and generates the resulting reaction.

[0030] Triggers for initiating mixing of the first and second reactive materials can be electrical or mechanical. For example, an electric signal can open a gate or initiate a force that can be triggered in response receiving an instruction from the computing system 200 via the temperature controlling device 124. Mechanical triggers can be automatic and based on the different expansion rates of metals due to temperature variations that activate a coil to wind or unwind. Such winding or unwinding of the coil can be a trigger by completing an electrical circuit that opens or breaks a gate or barrier is the conditions within the storage unit reach unacceptable levels.

[0031] In one embodiment, the temperature controlling device 124 can utilize a

thermoelectric device which creates a voltage when there is a different temperature on each side. An applied temperature gradient causes charge carriers in the interior volume of the storage unit 114 to diffuse from a hot side to a cold side or vice versa. The thermoelectric device can generate the thermoelectric effect, such as a Seebeck effect, a Peltier effect, or Thompson effect.

[0032] FIG. ID illustrates a block diagram of a coordinated decoupled delivery according to an exemplary embodiment. A UAV 106 that includes a temperature-controlled storage unit housing and storing a physical object can be transported to within a specified distance of a specified delivery location. A physical object can be loaded into the temperature-controlled storage unit and the UAV 106 can be loaded onto a temperature-controlled delivery vehicle 142. The temperature-controlled delivery vehicle 142 can include a temperature-controlled storage area 140. The temperature-controlled storage area 140 can maintain a specified temperature to assist in maintaining a specified temperature inside the storage unit. For example, the temperature-controlled storage area 140 can be refrigerated and/or heated.

[0033] In some embodiments, a user can request multiple physical objects to be delivered at a specified delivery location. At least one of the physical objects can be an object which needs a temperature-controlled environment. The computing system 200 can instruct a UAV 106 to deliver one or more physical objects which need a temperature-controlled environment to a specified delivery location. The at least one physical object can be loaded into the

temperature-controlled storage unit on the UAV 106 and the UAV 106 can be loaded into the temperature-controlled storage area 140 of the temperature-controlled delivery vehicle 142. The remaining physical objects can be loaded onto UAVs that do not have a temperature- controlled storage area and the UAVs can be loaded onto a delivery vehicle 146 which does not have a temperature-controlled environment. Alternatively, the remaining physical objects can be loaded onto the delivery vehicle without being loaded onto UAVs. The UAV 106 including a temperature-controlled storage unit can detect that the temperature-controlled delivery vehicle is within a specified distance of the specified delivery location. The UAV 106 can be ordered to be released from the temperature-controlled storage area 140 of the temperature-controlled delivery vehicle 142 by remote computer system 200 so that it can navigate to the delivery vehicle 146 containing the remaining physical objects for delivery. The UAV 106 can land on the roof of the delivery vehicle 146. Alternatively, in another embodiment, the roof of the delivery vehicle 146 can include a perforated screen and the UAV 106 can navigate inside the delivery vehicle through the perforated screen. The computing system 200 can time the release of the UAV 106 with the temperature-controlled product so that the delivery of all physical objects, including those that are not temperature- controlled, occurs at the same time.

[0034] FIG. IE illustrates a block diagram of a coordinated decoupled delivery with multiple catch sites according to an exemplary embodiment that allow the functional travel range of the UAV to be extended. In one embodiment, UAVs 106 including temperature-controlled storage units can be loaded onto a temperature-controlled delivery vehicle 142 including a temperature-controlled environment. Multiple delivery vehicles 146 without a temperature- controlled environment can be within a first specified radius 158 and a second specified radius 160 of the temperature-controlled delivery vehicle 142. In a non-limiting example the first specified radius can be 15 miles and the second specified radius can be 30 miles.

[0035] The UAVs 106 be instructed by the computing system 200 to deliver one or more physical objects to a specified delivery location. The UAVs 106 can detect that the temperature-controlled delivery vehicle is within a specified distance of the specified delivery location. The UAVs 106 can then be automatically be deployed from the temperature- controlled delivery vehicle 142 to navigate to one of the multiple delivery vehicles 146 which are not temperature-controlled. The delivery vehicles 146 can be catch sites for the UAVs 106. The UAVs can 106 land on the roof of the delivery vehicles 146. Alternatively, the roof of the delivery vehicles 146 can include a perforated screen and the UAVs 106 can navigate inside the delivery vehicles 146 through the perforated screen. The UAVs 106 can time their release so that the delivery of all physical objects to the same specified delivery location occurs at the same time. The UAVs 106 can also navigate to the appropriate delivery vehicle 146 which is navigating to the specified delivery location.

[0036] FIG. 2 is a block diagram illustrating a temperature-controlled delivery system according to an exemplary embodiment. The temperature-controlled delivery system 250 can include one or more databases 205, one or more servers 210, one or more computing systems 200, and UAVs 106. The UAVs 106 can include temperature-controlled storage units 112. The temperature-controlled storage units 112 can be configured to store and house one or more physical objects and can include sensors 116 and temperature-controlling devices 124. The sensors 116 can be temperature detection sensors configured to detect the temperatures of the interior volume of the temperature-controlled storage unit 112 and the one or more physical objects stored in the temperature-controlled storage unit 112. The temperature controlling devices 124 can be configured to control the temperature of the interior volume of the temperature-controlled storage unit 112. As noted above, the temperature -controlling devices may be, but are not limited to, one or more of, on-off controllers, autotune PID controllers, multiloop controllers, safety limit controllers, other types of controllers and temperature switches. In exemplary embodiments, the computing system 200 can be in communication with the databases 205, the server(s) 210, and the UAVs 106, via a communications network 215. The computing system 200 can implement at least one instance of a routing engine 220. The routing engine 220 may be an executable application or other executable process executed by the computing system 200. The routing engine 220 can implement the process of the temperature-controlled delivery system 250. The routing engine 220 will be described in detail herein.

[0037] In an example embodiment, one or more portions of the communications network 215 can be an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless wide area network (WW AN), a metropolitan area network (MAN), a portion of the Internet, a portion of the Public Switched Telephone Network (PSTN), a cellular telephone network, a wireless network, a WiFi network, a WiMax network, any other type of network, or a combination of two or more such networks.

[0038] The computing system 200 includes one or more computers or processors configured to communicate with the databases 205, and UAVs 106 via the network 215. The computing system 200 hosts one or more applications configured to interact with one or more components of the temperature-controlled delivery system 250. The databases 205 may store information/data, as described herein. For example, the databases 205 can include a locations database 225, physical objects database 230. The locations database 225 can include information associated with addresses and/or GPS coordinates of delivery locations. The physical objects database 230 can store information associated for physical object such as optimal temperatures. The databases 205 and server 210 can be located at one or more geographically distributed locations from each other or from the computing system 200. Alternatively, the databases 205 can be included within server 210 or computing system 200.

[0039] In exemplary embodiments, the computing system 200 can process instructions to retrieve one or more physical objects from a facility. The computing system 200 can execute the routing engine 220 in response to receiving the instructions. The instructions can include identifiers associated with the physical objects and a delivery location. The routing engine 220 can query the locations database 225 to retrieve the GPS coordinates of the delivery location. The physical objects can be retrieved and can be loaded onto a temperature- controlled storage unit 112 of a UAVs 106. In some embodiments, the routing engine 220 can instruct one or more UAVs 106 to navigate to the locations of the physical objects and to retrieve the physical objects from the facility.

[0040] The routing engine 220 can transmit instructions to the UAVs 106 to navigate to a specified location based on the GPS coordinates and to deliver the physical object at the delivery location. The physical object can be at a specified temperature when placed in the temperature-controlled storage unit 112. The sensors 116 can detect the temperature of the interior volume of the temperature-controlled storage unit 112 and the temperature of the physical object. The detected temperature may be encoded into communication signals and communication signals may be transmitted to the computing system 200. The computing system 200 can execute the routing engine 220 in response to receiving the communication signals. The routing engine 220 can decode the temperatures from the communication signals. The routing engine 220 can also determine that the temperature of the interior volume of the temperature-controlled storage unit 112 is greater than or less than a desired temperature of the physical object listed in the database. The routing engine 220 can control the temperature controlling device 124 to adjust the temperature of the interior volume of the temperature-controlled storage unit 112 to the determined ideal temperature and verify the temperature of the physical object.

[0041] In some embodiments, the routing engine 220 can receive the identifier of the physical object, prior to depositing the physical object in the temperature-controlled storage unit 112 (i.e. the identifier can be included in the instructions). The sensors 116 can detect a temperature of the interior volume of the temperature-controlled storage unit 112 and a temperature of the physical object, once the physical object is deposited in the temperature- controlled storage unit 112. The sensors 116 can determine when a change in temperature in the interior volume occurs that is greater that is greater than a specified threshold amount (e.g. one or two degrees). Based on exceeding the threshold, the sensors can encode the temperatures of the interior volume and the physical object into communication signals and transmit the communication signals to the computing system 200. The routing engine 220 can decode the temperatures from the communication signals. The routing engine 220 can query the physical objects database 230 using the identifier, to retrieve information associated with the physical object deposited in the temperature-controlled storage unit 112. The information can include, name, type of object, size, weight, dimensions and ideal storage temperatures. The routing engine 220 can determine an ideal temperature at which to store the physical object based on the retrieved set of information. The routing engine 220 can control the temperature controlling device 106 to adjust the temperature of the interior volume of the temperature-controlled storage unit 112 to the determine ideal temperature.

[0042] In some embodiments, a routing engine 220 can receive instructions to retrieve and deliver a first and second physical object to a delivery location. The instructions can include a first and second identifier associated with the first and second physical object respectively. The sensors 116 can detect a temperature of the interior volume in response to the first and second physical object being deposited in the temperature-controlled storage unit 112 of the UAV 106. The sensors 116 can determine if the temperature subsequently changes by more than a specified threshold amount. Based on the temperature change exceeding the threshold amount the temperature may be encoded into communication signals (by either the sensors, temperature-controlling device or other device in the storage unit equipped with network communication ability) and transmitted to the computing system 200. The computing system 200 can execute the routing engine 220 in response to receiving the communication signals. The routing engine 220 can decode the temperatures of the interior volume, first physical object and/or the second physical object from the communication signals. The routing engine 220 can query the physical objects database 230 using the first and second identifier to retrieve information associated with the first and second physical object. The information can include, name, type of object, size, weight, dimensions and ideal storage temperatures. The routing engine 220 can calculate an ideal temperature to store both the first and second physical objects based on the retrieved information of the first and second physical objects. The routing engine 220 can control the temperature controlling device 106 to adjust the temperature of the interior volume of the temperature-controlled storage unit 112 to the calculated ideal temperature.

[0043] In some embodiments, a routing engine 220 can receive a request for multiple physical objects to be delivered at a specified delivery location. At least one of the physical objects can be an object which needs a temperature-controlled environment. The at least one physical object can be loaded into the temperature-controlled storage unit 112 on the UAV 106 and the UAV 106 can be loaded into the temperature-controlled storage area a temperature-controlled delivery vehicle. The routing engine 106 can instruct the UAV 106 to deliver the physical object to a specified location. The instructions can include an

identification of the delivery vehicle which is navigating to the specified delivery location. The remaining physical objects can be loaded onto UAVs that do not have a temperature- controlled environment and the UAVs can be loaded onto a delivery vehicle which does not have a temperature-controlled environment. Alternatively, the remaining physical objects can be loaded onto the delivery vehicle without being loaded onto UAVs. The UAV 106 including a temperature-controlled storage unit 112 can detect that the temperature-controlled delivery vehicle is within a specified distance of the specified delivery location. The UAV 106 can be instructed by the computing system 200 to be released from the temperature- controlled storage area of the temperature-controlled delivery vehicle and can identify and navigate to the delivery vehicle containing the remaining physical objects for delivery. The UAV 106 can land on the roof of the delivery vehicle. Alternatively, the roof of the delivery vehicle can be a perforated screen and the UAV 106 can navigate inside the delivery vehicle through the perforated screen. The computing system 200 can time the release of the UAV 106 so that the delivery of all physical object occurs at the same time.

[0044] As a non- limiting example, the temperature-controlled delivery system 250 can be implemented in a retail store. The computing system 200 can receive instructions to retrieve one or more products from a retail store. The computing system 200 can execute the routing engine 220 in response to receiving the instructions. The instructions can include identifiers associated with the products and a delivery location. The routing engine 220 can query the locations database 225 to retrieve the GPS coordinates of the delivery location. The products can be retrieved and can be loaded onto a temperature-controlled storage unit 112 of a UAVs 106. In some embodiments, the routing engine 220 can instruct one or more UAVs 106 to navigate to the locations of the products and to retrieve the products from the retail store.

[0045] The routing engine 220 can transmit instructions to the UAVs 106 to navigate to a specified location based on the GPS coordinates to deliver the product at the delivery location. The product can be of a specified temperature when placed in the temperature- controlled storage unit 112. The sensors 116 can detect the temperature of the interior volume of the temperature-controlled storage unit 112 and the temperature of the product. The sensors 116 can detect a change in temperature of the interior volume that is greater than a specified threshold amount. The sensors 116 can encode the temperature into communication signals and transmit the communication signals to the computing system 200. The computing system 200 can execute the routing engine 220 in response to receiving the communication signals. The routing engine 220 can decode the temperatures from the communication signals. . The routing engine 220 can determine an ideal temperature for storing the product in the temperature-controlled storage unit 112. The routing engine 220 can control the temperature controlling device 124 to adjust the temperature of the interior volume of the temperature-controlled storage unit 112 to the determined ideal temperature.

[0046] In one embodiment, instead of the sensor or the temperature controlling device on the UAV determining that a temperature change of the interior volume exceeds a threshold amount, the temperature may just be periodically detected and transmitted to the remote computing system which analyzes the temperature to make sure it is still within a change threshold. In the event the temperature is determined to have undergone a change exceeding the threshold, the computing system may determine the ideal temperature for stored physical objects and instruct the temperature-controlling device as described herein. [0047] In some embodiments, the routing engine 220 can receive the identifier of the product, prior to depositing the product in the temperature-controlled storage unit 112 (i.e. the identifier can be included in the instructions). The sensors 116 can detect a temperature of the interior volume of the temperature-controlled storage unit 112 and a temperature of the product, once the physical object is deposited in the temperature-controlled storage unit 112. The sensors 116 can determine if the change in temperature is greater than a specified threshold amount. The sensors can encode the detected temperature of the interior volume into communication signals and transmit the communication signals to the computing system 200. The routing engine 220 can decode the temperatures from the communication signals. The routing engine 220 can query the physical objects database 230 using the identifier, to retrieve information associated with the product deposited in the temperature-controlled storage unit 112. The information can include, name, type of object, size, weight, dimensions and ideal storage temperatures. The routing engine 220 can determine an ideal temperature at which to store the product based on the retrieved set of information. The routing engine 220 can control the temperature controlling device 106 to adjust the temperature of the interior volume of the temperature-controlled storage unit 112 to the determine ideal temperature.

[0048] In some embodiments, a routing engine 220 can receive instructions to retrieve and deliver a first and second product to a delivery location. The instructions can include a first and second identifier associated with the first and second products respectively. The sensors 116 can detect a temperature of the interior volume, the first product and the second product, in response to the first and second products being deposited in the temperature-controlled storage unit 112 of the UAV 106. The sensors 116 can determine the change in temperatures of the interior volume, first and/or second products is greater than a specified threshold amount. The sensors 116 can encode the temperatures into communication signals and transmit the communication signals to the computing system 200. The computing system 200 can execute the routing engine 220 in response to receiving the communication signals. The routing engine 220 can decode the temperatures of the interior volume, first physical object and/or second physical object from the communication signals. The routing engine 220 can query the physical objects database 230 using the first and second identifier to retrieve information associated with the first and second products. The information can include, name, type of object, size, weight, dimensions and ideal storage temperatures. The routing engine 220 can calculate an ideal temperature to store both the first and second products based on the retrieved information of the first and second products. The routing engine 220 can control the temperature controlling device 106 to adjust the temperature of the interior volume of the temperature-controlled storage unit 112 to the calculated ideal temperature.

[0049] In one embodiment, the sensors 116 can detect the outside temperature at a specific altitude, while the UAV is aerially en route to a specified destination. The sensors 116 can encode the outside temperatures into communication signals and transmit the communication signals to the computing system 200. The computing system 200 can execute the routing engine 220 in response to receiving the communication signals. The routing engine 220 can decode the outside temperatures. The routing engine 220 can query the physical objects database 230 using the first and second identifier to retrieve information associated with the first and second products. The routing engine 220 can calculate an ideal temperature to store both the first and second products based on the retrieved information of the first and second products. The routing engine 220 can control the temperature controlling device 106 to adjust the temperature of the interior volume of the temperature-controlled storage unit 112 to the calculated ideal temperature, based on the detected outside temperature.
