     FIELD 
     The disclosed embodiments relate generally to mobile platforms and more particularly, but not exclusively, to methods, apparatus, and kits for assembling a mobile platform, such as an unmanned aerial vehicle. 
     BACKGROUND 
     Mobile platforms, such as manned vehicles and unmanned vehicles, can be used for performing surveillance, reconnaissance, and exploration tasks for military and civilian applications. For example, an unmanned aerial vehicle (UAV) may be outfitted with a functional payload, such as sensors for collecting data from the surrounding environment or a substance to be delivered to a destination. 
     A power device is a component installed on a mobile platform for providing power to a portion of, or all of, components on the mobile platform that consumes power. For example, a power device on a UAV may include a battery. Generally, during an operation of the UAV, the battery internally generates a significant amount of heat. For example, a lithium battery powering the UAV can have a surface temperature ranging from about 70 degrees Celsius to about 80 degrees Celsius. The high temperature may reduce the lifetime of the battery and other components of the UAV that are installed adjacent to the battery. When the UAV does not fully dissipate the heat generated by the battery, the battery may catch a fire even during a normal operation of the UAV. 
     In addition, the battery is one of the heaviest components on the UAV. In the event of an accident, e.g., when a UAV crashes to the ground, an impact force of the battery on the ground may cause the battery to explode or catch a fire, resulting in a complete destruction of the UAV. 
     Further, some UAVs have framework and other structural components that are made of carbon fiber board because carbon fiber board has advantages such as low weight and high tensile strength. The carbon fiber board also provides space for installing a battery of a UAV. The battery can be attached to the carbon fiber board using two methods. In one method, a slot is opened on a carbon fiber board for holding a fixing tape for fixing the battery on the carbon fiber board. In the other method, a slot is opened on a carbon fiber board, and a screw can be used for fixing a battery on the carbon fiber board via the slot. Both methods require complicated procedures for installing and uninstalling the battery and may require usage of special tools. 
     Moreover, slots opened on a carbon fiber board using common processes usually have rough edges that may pierce the battery, and carbon fiber board is a conductor. Thus, both methods may have safety issues for a user, such as electric short circuit. When a UAV crashes to the ground in an accident, the carbon fiber board may fold upon being subjected to an impact force. The folded carbon fiber board may have a sharp tip to pierce the battery and cause the battery to burn. 
     In view of the foregoing, there is a need for a method and apparatus for installing a power device on a mobile platform to achieve easy installation and desired heat dissipation of the power device, reduce damage caused by the power device during an accident, and/or improve the operating condition of the power device and the entire mobile platform.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     Since currently-available power device installation on a mobile platform is incapable of providing sufficient heat dissipation and operational safety, a method, apparatus, and/or kit that optimizes heat dissipation and operational safety can prove desirable and provide a basis for a wide range of mobile platform applications. Such a method, apparatus and/or kit, for example, can enable the mobile platform to operate in harsh operating conditions, such as in a dusty, corrosive, and/or humid environment, that require the mobile platform being air sealed in a housing. This result can be achieved, according to one embodiment disclosed herein, by a mobile platform  100  as illustrated in  FIG. 1 . 
     The mobile platform  100  may refer to any appropriate apparatus that is capable of moving over a distance. Exemplary mobile platforms can include, but are not limited, to automobiles, buses, trains, aircrafts, ships, and other types of vehicles. For illustrative purposes, the mobile platform can include an Unmanned Aerial Vehicle (UAV), and an operation may include a flight of the UAV. However, wherever a UAV is described in the disclosed methods, devices and systems, the UAV may be replaced by another appropriate mobile platform, and a flight may be replaced by another operation associated with a mobile platform, without deviating from the concept covered in the scope of the present disclosure. 
     Turning to  FIG. 1 , the mobile platform  100  is shown as including a control device  200  and a power device  500 . The control device  200  can include processing hardware for performing data acquisition, data processing, and any other functions and operations described herein for controlling an operation of the mobile platform  100 . Without limitation, the control device  200  can include one or more general purpose microprocessors (for example, single or multi-core processors), application-specific integrated circuits, application-specific instruction-set processors, graphics processing units, physics processing units, digital signal processing units, coprocessors, network processing units, audio processing units, encryption processing units, and the like. The control device  200 , for example, can include a processor (not shown) for performing at least a portion of, or all of, the disclosed functions of the control device  200 . Although described as including a single transceiver for purposes of illustration only, the control device  200  can include any suitable number of uniform and/or different processors. 
     Additionally and/or alternatively, the control device  200  can include a transceiver, which can include RF circuitry or any other appropriate hardware and any appropriate software instructing the hardware for receiving and/or transmitting data. For example, the transceiver can receive operational commands from a remote controller and send the operational commands to the processor to execute. The transceiver can transmit data generated by the processor, such as location and/or travel speed of the mobile platform  100 , to the remote controller. Although described as including a single transceiver for purposes of illustration only, the control device  200  can include any suitable number of uniform and/or different transceivers. 
     Additionally and/or alternatively, the control device  200  can include a sensor (not shown). The sensor can collect data of characteristics of the mobile platform  100  including, e.g., travel speed and/or posture of the mobile platform  100 , temperature and/or atmospheric pressure at a location of the mobile platform  100 . Exemplary sensors can include a location data unit, an odometer, an inertial measurement unit, an accelerometer, and the like. The sensor can send the collected data to the processor of the control device  200  for controlling the mobile platform  100  accordingly. Although described as including a single sensor for purposes of illustration only, the control device  200  can include any suitable number of uniform and/or different sensors. 
     The power device  500  in  FIG. 1  can include any device that supplies power to the control device  200  and/or other component(s) of the mobile platform  100 . The power device  500  can be installed outside the control device  200 . Further, the power device  500  can be coupled with the control device  200  via any suitable electrical and/or mechanical connections.

       FIG. 2  is a top level flow chart illustrating an embodiment of a method  2000  for assembling the mobile platform  100  (collectively shown in  FIG. 1 ). As shown in  FIG. 2 , the power device  500  is installed, at  2001 , outside the control device  200  coupled with the mobile platform  100 . By being located outside the control device  200 , the power device  500  is not surrounded by, and/or in physical contact with, processors, transceivers and/or other electronic components of the control device  200 . The power device  500  can be associated, at  2002 , with the mobile platform  100 . Associating the power device  500  with the mobile platform  100  can include forming connection between the power device  500  and the mobile platform so the power device  500  can provide power to the mobile platform and/or receive control signals from the mobile platform. Further, connection between the power device  500  and the mobile platform  100  can also enable the mobile platform  100  to carry the power device  500  during operation.

Exemplary operating positions may include a landing position, a pre-flight position, a flight position, and/or the like. 
     As shown in  FIG. 15 , the support member  400  can extend from the mobile platform  100  downwardly (or toward the ground). The power device  500  can be located on a skyward surface of the module  700 , between the module  700  and the control device  200 . The power device can be separate and/or detached from the housing  800  that encloses the control device  200 . Further, as illustrated in  FIG. 15 , the control device  200  and the motor  300  of the mobile platform  100  can be located above (closer to the sky than) the power device  500 . 
       FIG. 16  is a detail drawing of another alternative embodiment of the mobile platform of  FIG. 3 , wherein a perspective view of the mobile platform is shown to further illustrate details of the exemplary mobile platform  100 . As shown in  FIGS. 15 and 16 , an arm  310  connecting the control device  200  with the motor  300  can be folded. 
       FIG. 17  is a detail drawing of still another alternative embodiment of the mobile platform of  FIG. 3 , wherein the mobile platform has extended motor arms and the power device  500  is installed outside the control device  200  in accordance with the method  2000  of  FIG. 2 . In  FIG. 17 , the arm  310  connected to each motor  300  is extended, in comparison with the arm  310  being in  FIG. 16 . Further, the tape  702  in  FIGS. 15-16  is omitted in  FIG. 17 . 
       FIGS. 15-17  show the module  700  as having one skyward surface when the mobile platform  100  is in an operating position, and the power device  500  is installed on the skyward surface. However, the module  700  can have a different shape from the shape as shown in  FIGS. 15-17 , and the power device  500  can be installed on a surface of the module  700  facing any direction, without limitation. 
     In various embodiments, the power device  500  can be installed on a skyward surface of the module  700 . A skyward surface can refer to a surface completely or partially skyward. A completely skyward surface can face a direction pointing to the sky (i.e., a completely skyward direction) during normal operation of the mobile platform. A partially skyward surface can face a direction away from the completely skyward direction by an angle that is greater than 0 degree and less than 90 degrees. The module  700  can have multiple skyward surfaces when the mobile platform  100  is in a certain operating position, depending on the specific shape and specific orientation of the module  700 . 
     In various embodiments (e.g., in  FIGS. 15-17 ), the module  700  and the power device  500  are shown as not being enclosed in a housing  800  in an operating position. However, the mobile platform  100  can have multiple operating positions. A structure of the mobile platform  100  can be adjusted based on the specific positions. For example, a housing  800  can be configured to enclose the power device  500  and/or the module  700  when the mobile platform  100  is in a landing position when the mobile platform  100  lands on the ground. In a landing position, the power device  500  and/or the module  700  can be retrieved into the housing  800  by an elevator structure. In that case, the power device  500  and/or the module  700  can be released out of the housing  800  by the elevator structure in a flight position. 
     During an operation of the mobile platform  100 , the power device  500  can generate a significant amount of heat. If the power device  500  is positioned within an enclosed housing  800  where the heat cannot be dissipated sufficiently, the lifetime of the power device  500  can be significantly reduced. When a housing  800  encloses the power device  500  as well as the control device  200  and/or the motor  300 , the heat dissipation may be limited in such a way as to reduce the lifetime of devices of the control device  200  and/or the motor  300 , and even to start a fire. 
     Certain conventional mobile platforms, such as UAVs, enclose the power device  500  in a housing that has a partially open structure. That is, heat dissipation holes are opened on the housing for exchanging air between interior of the housing and exterior of the housing. However, for certain applications, the UAV may need to be operated in a harsh environment including, e.g., corrosive, dusty, and/or humid air. In those cases, air sealing the electronic components (e.g., control device, motor) of the UAV is desirable. The heat dissipation of an air sealed UAV can be significantly limited. The power device  500 , such as a battery, thus can become a safety hazard. A cooling system may be installed in the housing  800  to cool the power device. The cooling system can add significant weight to the UAV and thus considerably reduce flight time of the UAV. 
     According to the method  2000  of  FIG. 2  and mobile platform  100  of  FIGS. 3-17 , the power device  500  can be exposed to exterior environment of the mobile platform  100 . Thus, the power device  500  can have the generated heat quickly dissipated into the surrounding air. 
     Further, the power device  500  can be installed on the module  700  that can also be located outside a housing  800  and exposed to the exterior environment of the mobile platform  100 . In certain embodiments, the module  700  can include a container for holding one or more flowable substances, such as water, pesticide, and the like. Heating the flowable substances generally requires a great amount of heat. Therefore, the flowable substances in the module  700  can further cool down the power device  500 . 
     As shown in  FIGS. 6-14 , the power device  500  can be located in a recess  730  on the module  700 . The contact area between the power device and the module  700  can be adjusted by varying the size and shape of the recess  730 . A greater contact area can result in greater heat dissipation. In  FIGS. 5-14 , the contact area can range from the surface area of one side of the power device  500  to the surface area of multiple sides of the power device  500 . Thus, desired heat dissipation can be achieved. 
     Further, certain UAVs may be used for spraying the flowable substance(s), such as water and/or pesticide, contained in the module  700 . Thus, during an operation, the exterior air of the UAV can become corrosive and humid. A UAV thus needs to air seal various electronic components in a housing  800 . Locating the power device  500  out of the housing  800  and on the module  700  can fully utilize the module  700  to solve the heat dissipation problem without introducing additional equipment. On the other hand, the module  700  does not necessarily include the container  791  for holding the flowable substance. The module  700  can include the payload  790  and/or the power device support for supporting the power device  500 . 
     Further, as shown in  FIGS. 8-14 , installing the power device  500  on the module  700  advantageous utilizes simple and safe manual operations without a need for special tools. Danger of electrical short circuit can also be minimized. 
     Still further, as previously described, when the power device  500  and the module  700  are subjected to an impact force, the module  700  can function as a shock absorber for cushioning the impact force on the power device  500 . Damage to the power device  500  advantageously can be reduced. In the event of a crash of a UAV when the power device  500  and the module  700  fall to the ground, the module  700  may land between the power device  500  and the ground to absorb the shock in the crash and prevent the power device  500  from breaking apart or catching a fire. 
     In addition, the module  700  can be further coupled with the mobile platform  100  via a reinforcement structure (not shown). The reinforcement structure can be installed on a portion of the module  700  other than a position of the power device  500 , to avoid interfering with shock absorbing effect of the module  700  for the power device  500 . The reinforcement structure can include any conventional structures (e.g., metallic framework installed on edge of the module  700 ), to restrict movement of the module relative to the mobile platform  100  and increase structural strength of module  700 . 
     In addition, conventionally, a control device and a power device are enclosed in a common housing, and/or the power device is located above the control device. In the event of a crash, the power device can be subjected to a significant impact force and may transfer the impact force to the control device. In some cases, the power device can fall onto, and crush, the control device. However, in  FIGS. 15-17 , in an operating position of the mobile platform  100 , the control device  200  can be located above the power device  200 . As the module  700  may land between the power device  500  and the ground to absorb the shock for the power device  500 , the control device  200  and the motor  300  can fall on the power device  500 . The control device  200  is generally significantly lighter than the power device  500 , so damage to the control device  200  can be considerably reduced. 
     Protection to the mobile platform  100  can be further enhanced by releasing the power device  500  from the rest of the mobile platform  100  during a crash. A quick release mechanism can be used for associating the power device  500  with the mobile platform  100 . 
     In certain embodiments, the module  700  can be coupled with the mobile platform  100  using the quick release mechanism, so the power device  500  can be released from the mobile platform  100  when installed on the module  700 . 
       FIG. 18  is a detail drawing of still another alternative embodiment of the mobile platform  100  of  FIG. 3 , wherein an exploded-view diagram of the power device  500 , the module  700  and the support member  400  is shown.  FIG. 18  shows an assembly including the power device  500 , the module  700  and the support members  400  of  FIG. 3 . In  FIG. 18 , the module  700  can include two recessive slots (not shown) on each of the two opposite side surfaces, respectively. A fixing column stopper  762  can be plugged into the recessive slot. The fixing column stopper  762  can include a plug made of an elastic material, e.g., a rubber plug. The fixing column stopper  762  can include a concaved slot to receive a fixing column  763 . 
     The fixing column  763  can be connected to a support member  410  that is a portion of the support member  400 . The support member  410  can include a bar-shaped structure. For example, the support member  410  can be encircled in a fixture  764  having a hoop shape. The fixture  764  encircling the support member  410  can be connected to the fixing column  763  using a screw  765  (e.g., an M5 screw or the like). 
     Optionally, two adjacent support members  410  can be connected with each other via a crossbeam fixture  420 . The crossbeam fixture  420  can be shaped to include a spray bar fixture  421  used for holding a spray head or sprinkler head for spraying the liquid contained in the module  700 . 
     As previously mentioned, the module  700  can include a holder  703  for holding the tape  702 . In one example, the holder  703  can include a hole defined by surface shape of the module  700  (as in  FIG. 10 ). In another example, the holder  703  can include one or more tape holder slots  704  formed adjacent to the recess  730 . The holder slots  704  can be defined by the surface shape of the container. A lock ring  705  can snap into the holder slots  704  to form a hole for the tape  702  to pass through. 
       FIG. 19  is a detail drawing of still another alternative embodiment of the mobile platform  100  of  FIG. 3 , wherein an assembly including the power device  500 , the module  700  and the support member  400  is shown. The mobile platform  100  can include the assembly in  FIG. 19  in an operating position. When the mobile platform  100  includes the assembly in FIG.  19  in a landing position, the support member  400  can be used as a landing support member of the mobile platform  100 . 
     When the mobile platform  100  lands on a ground, the support member  400  can tilt in such a way that the support member  410  is at an angle (i.e., an initial angle) relative to a groundwardly direction. For example, the angle can range from 10 degrees to 35 degrees. 
     In the event of a crash, upon touching the ground, the support member  410  can be subjected to an impact force. The support member  410  is coupled with the module  700  via the fixing column stopper  762  rather than a rigid connection. Therefore, when the impact force is equal to or greater than a predetermined impact force, the support member  410  can be tilted at an angle greater than the initial angle, pull the fixing column stopper  762  out of the recessive slot, and release the module  700 . Thus, the module  700  assembled with the power device  500  can be released from the rest of the mobile platform  100 , and falls separately from the control device  200  and the motor  300 . 
     Generally, when the mobile platform  100  includes a UAV, a total weight of the module  700  filled with a flowable substance and the power device  500  can be greater than a weight of the mobile platform  100 . In some cases, a total weight of an empty module  700  and the power device  500  can be greater than a weight of the rest of the mobile platform  100 . When the quick release mechanism is used, even when the power device  500  is still subjected to an impact force, the power device  500  does not transfer the impact force to the control device  200 . The control device  200  is much lighter than the power device  500  and the module  700 , so the crash may not result in a significant damage to the control device  200 . 
     Further, in the event when the power device  500  still catches a fire, the control device  200  is released from the power device  500  and can be prevented from being burned. Damage to the mobile platform  100  can thus be significantly reduced.  FIG. 20  is a detail drawing of still another alternative embodiment of the mobile platform  100  of  FIG. 3  once the power device  500 , the module  700  and the support member  400  are assembled. 
     The quick release mechanism can include mechanisms in addition/alternative to the structure shown in  FIG. 18 . For example, the power device  500  and/or the module  700  can be released upon being subjected to a threshold condition. The control device  200  and/or the motor can determine wither the threshold condition is met. 
     In one example, the support member  400  can be controlled by the control device  200  electronically. Via a sensor, the control device  200  can determine that a threshold condition is reached. The threshold condition can include, e.g., the mobile platform  100  is descending at a speed faster than a threshold descending speed. The control device  200  can then instruct the support member  400  to increase the tilting angle of the support member  410  to release the power device  500  and/or the module  700 . In another example, via a sensor, the control device  200  can determine that the support member  410  is touching the ground with an impact force greater than a threshold descending speed. The control device  200  can then increase the tilting angle of the support member  410  to release the power device  500  and/or the module  700 . 
     Further, to achieve a quick release mechanism, any electrical/mechanical connection can be used for associating the power device with the mobile platform  100 , not limited to the fixing column stopper  762  in  FIG. 18 . For example, the module  700  can rest on support rods or support platens installed on each support member  410 . The support member  410  can increase the tilting angle and/or move laterally away from the module  700  to release the module  700 . 
     Moreover, the power device  500  and/or the module  700  can be coupled to the mobile platform  100  without using the support member  400 , and the quick release mechanism can also function. For example, the module  700  can be connected to a fixture located on the external wall of the housing  800 . The fixture can be controlled by the control device  200  to release the module  700  upon being subjected to the predetermined impact force, or when the sensor detects that a threshold condition is reached. 
     As previously described, the module  700  can include a container for holding a flowable substance. When the container contains the liquid, heat dissipation for the power device can be improved. However, when the container is partially filled with the liquid, the liquid can drift or shake with motion of the mobile platform  100 . When the mobile platform  100  changes travel direction, the center of mass of the mobile platform  100  needs to be changed within a short time. Inertia of the liquid can cause the mobile platform  100  to lose balance and even fall to the ground. 
     Thus, an anti-drift structure can be installed in the module  700  to obstruct the movement of the liquid. In the present disclosure, wherever a liquid is described in the disclosed methods, apparatus and systems, the liquid may be replaced by another flowable substance, without deviating from the concept covered in the scope of the present disclosure. 
     The anti-drift structure can include a spacer board fixed at one or more locations within the module  700 .  FIG. 21  is an exemplary structure diagram of an alternative embodiment of the module  700  of  FIG. 3 , wherein the module  700  has a spacer board installed therein. The module  700  can have one or more spacer board  770  installed therein. Each spacer board  770  can be installed at a regular interval or random interval, and can be parallel or tilted relative to one or more other spacer boards  770 . One or more holes  771  can be formed within each spacer board  770 . In certain embodiments, between two adjacent spacer boards  770 , the position of the holes can be misaligned. That is, a liquid may encounter obstacle when drifting in a direction vertical to the spacer boards  700  and moving from each spacer board  700  through the holes  771 . The holes  771  on each spacer board  770  can include any arrangement for achieving anti-drift effect based on the movement of the mobile platform  100 , without limitation. 
     Additionally and/or alternatively, the anti-drift structure can also include one or more hollow structures.  FIG. 22  is a detail drawing of an embodiment of hollow structures  780  adapted to be placed in the module  700  of  FIG. 3 . The hollow structure  780  can thus be also referred to as an internal structure  780 . The hollow structure  780  can include a shell  782  and one or more holes  781  thereon. Liquid can penetrate into the hollow structure  780  via the hole  781 . Because liquid has to drift through the hole  781 , the hollow structure  780  can partially block the liquid from drifting freely and thus restrict movement of the liquid. 
     The anti-drift structure is not limited to the hollow structures  780  illustrated in  FIG. 22 . For example, the anti-drift structure can include porous structures. A porous structure does not necessarily include the shell  782  and/or the holes  781  shown in  FIG. 22 . A porous structure can include a solid that is has any shape and/or size. An interior of the porous structure can include multiple pores for enabling a liquid to permeate the porous structure. The porous structure can inhibit the liquid from drifting freely and thus restrict movement of the liquid. 
     In certain embodiments, the hollow structure  780  can have a size (e.g., a diameter when the hollow structure includes a sphere) less than a size of the opening of the module  700  (covered by the lid  701  in  FIG. 8 ). Thus, the hollow structure  780  can be placed into and removed out of the module  700  as desired. As a non-limiting example, the hollow structure  780  can have a diameter ranging from 60 mm to 100 mm. The number of hollow structures  780  in the module  700  is not limited in the present disclosure. The hollow structures  780  can partially and/or completely fill the interior of the module  700 . 
     The number of holes  781  on the hollow structure  780  and size of the holes  781  can be adjusted according to specific requirements of the anti-drift function of a specific mobile platform  100  and size/shape of the module  700 , without limitation. As a non-limiting example, the hollow structure  780  can have the number of holes  781  ranging from 5 to 30, and the hole  781  can have a diameter ranging from 5 mm to 15 mm. In general, a hole  781  having a great size may have less anti-drift effect, and a hole  781  having a small size may result in liquid residue in the hole when the liquid needs to be depleted from the module  700 . The size of the hole  781  can be optimized based on viscosity of the liquid and requirements of the anti-drift ability. 
       FIG. 23  is a detail drawing of an alternative embodiment of the module  700  of  FIG. 3 , wherein a perspective view of the module  700  is shown.  FIG. 23  illustrates the module  700  as having therein hollow structures of  FIG. 22 . For illustrative purposes, a portion of the interior of the module  700  is opened to show the hollow structure  780  placed in the module  700 . 
       FIG. 24  is a detail drawing of another alternative embodiment of the module  700  of  FIG. 3 , wherein a side view of the module  700  is shown.  FIG. 24  illustrates the module  700  as having therein hollow structures  780  of  FIG. 22 . For illustrative purposes, a portion of the interior of the module  700  is opened to show the hollow structure  780  placed in the module  700 . 
       FIG. 22  illustrates the hollow structure  780  as a hollow sphere. However, the hollow structure  780  can also have other geometric bodies such as ellipsoid, cube, and the like, without limitation. 
     Optionally, the container can have a lowest-level position  706  (as shown in  FIG. 26 ). The lowest-level position  706  can be located at a lowest point (i.e., a point closest to the ground) of the container when the mobile platform  100  is in an operating position. Thus, liquid remaining in the container can flow to the lowest-level position  706 . The liquid can thus be completely drained via an opening at the lowest-level position  706 . 
     Although  FIG. 3  illustrates the module  700  as including the payload  790 , the module  700  does not necessarily include only the payload  790 . Alternatively and/or additionally, the module  700  can include a power device support. For example,  FIG. 25  is a top level block diagram illustrating an alternative embodiment of the mobile platform  100  with the power device  500  and the module  700 . The module  700  can include a power device support  792 . The power device support  792  can comprise any structure for holding and/or otherwise supporting the power device  500 . Exemplary structures for holding and/or otherwise supporting the power device  500  can include a box, a shelf, a cradle, a support frame, and/or the like, without limitation. In one example, the power device support  792  can be installed on, and/or integrated with, the payload  790  and hold and/or otherwise support the power device  500 . In another example, the power device support  792  can be used for holding and/or otherwise supporting the power device  500  and can be connected to the mobile platform  100  without the need of connecting with the payload  790 . 
     Various embodiments also provide a method for manufacturing the module  700  in  FIG. 3 . The method can include forming a container adapted to hold a flowable substance. A portion of, or all of, the disclosed structures for installing the power device  500  on the module  700  and coupling the module  700  to the mobile platform  100 , and the spacer boards  770  can be formed as an integral part of the container by shaping the shell of the container. In a non-limiting example, the container can be made of a material including a polymer, e.g., polyvinyl chloride, polyethylene, polystyrene, and/or the like. Materials other than polymer can also be used. In a non-limiting example, the shell of the container can be made of a material having a Young&#39;s Modulus less than 20 GPa. The method can include making the container using a blow molding process, a compression molding process, and/or other conventional molding processes. 
     Further, the method for manufacturing the module  700  can further include manufacturing the hollow structures  780  adapted to be placed in the container. The hollow structures  780  can be made of a material, different from, similar to, or the same as the material of the container and can be made using a process similar to or the same as the manufacturing process for making the container. 
     Although  FIGS. 8-20  illustrates the power device  500  as being exposed to the external operating environment of the mobile platform  100 , the power device  500  can be located outside the control device  200  without necessarily being exposed to the external operating environment of the mobile platform  100 . 
     For example,  FIG. 26  is a block diagram illustrating another alternative embodiment of the mobile platform  100  of  FIG. 3 , wherein the power device  500  is installed in a power housing  890 . The power housing  890  can communicate with the support member  400  (as shown in  FIG. 3 ). The support member  400  is illustrated as including a first support member  411  and a second support member  412 . For example, the first support member  411  and/or the second support member  412  can have a bar-shaped structure, or any other structures, without limitation. Although described as communicating with two support members  411 ,  412  for purposes of illustration only, the power housing  890  can communicate with one support member, or any suitable number of uniform and/or different support members. 
     The support members  411  and  412  can have a hollow and/or porous interior so air can flow therein. The power housing  890  can communicate with the housing  800  that encloses the control device  200 . An air duct  850  can connect the power housing  890  and the housing  800 . Thus, the support members  411  and  412 , the air duct  850 , the power housing  890 , and the housing  800  can form an air-sealed chamber  860 . 
     An air outlet  830  can be opened on the support members  411  and/or  412 . An air inlet  840  can be opened on the housing  800 . A pump  810  can be installed in the housing  800  for forming an air flow  820 . The pump  810  can draw air from the external operating environment of the mobile platform  100 . The air can enter the chamber  860  via the air inlet  840 . The pump  810  can pressure the air into the power housing  890 . The air can thus exit the chamber  860  via the air outlet  830 . 
     Although described as being located in the housing  800  for purposes of illustration only, the pump  810  can be located in any suitable locations in the mobile platform  100 . For example, the motor  300  (as shown in  FIG. 3 ) can be enclosed in a housing that communicates with the housing  800 . The pump  810  can be in the housing enclosing the motor  300 . Additionally and/or alternatively, the pump  810  can be integrated with the motor  300 . Regardless of the location of the pump  810 , the pump  810  can be configured to generate the air flow  820  that can traverse the power housing  890 . 
     As shown in  FIG. 26 , the power device  500  can be enclosed in the power housing  890 . The power device connection  510  connecting the power device  500  and the power interface  600  can be enclosed in the air duct  850 . Thus, in a harsh operating environment, the power device connection  510  and the power device  500  can be protected. Meanwhile, the air flow  820  can enter the power housing  890  from the housing  800 . The power device  500  can be generally at a higher temperature than the control device  200  during operation of the mobile platform  100 . Therefore, the air flow  820  from the housing  800  can be cooler than the power device  500 , thereby effectively reducing the temperature of the power device  500 . 
     Although described as connecting the power housing  890  with the housing  800  enclosing the control device  200  for purposes of illustration only, the air duct  850  can connect the power housing  890  with a housing enclosing any other component of the mobile platform  100 . For example, the air duct  850  can connect the power housing  890  with the housing enclosing the motor  300 . The air flow  820  can enter the power housing  890  from the housing enclosing the motor  300 . 
     The power housing  890  does not necessarily connect with the housing  800  via the air duct  850 . In certain cases, the air duct  850  can be omitted. For example, the support member  400  can be configured to connect the power housing  890  with the housing  800 .  FIG. 27  is a block diagram illustrating an alternative embodiment of the mobile platform of  FIG. 26 , wherein the air flow  820  enters the power housing  890  via the first support member  411  and exits the power housing  890  via the second support member  412 . As shown in  FIG. 27 , the pump  810  can be configured to pump the air flow  820  into the power housing  890  via the first support member  411 . The air flow  820  can traverse the power housing  890  to cool the power device  500 , and then exit via the air outlet opened on the second support member  412 . 
     As shown in  FIG. 27 , the first support member  411  and the second support member  412  can be coupled with the power housing  890  via a connection  430 . The connection  430  can be configured to enable the quick release mechanism as shown in  FIG. 18 . Thus, when the first support member  411  and/or the second support member  412  are subjected to an impact force, and/or the control device  200  detects that a preset threshold condition is met, the power housing  890  can be released from the mobile platform  100 , to reduce damage to the control device  200  during an accident. 
     Various embodiments also provide a kit for assembling a mobile platform. The kit can include one or more of the control device  200 , the module  700 , and the power device  500  as illustrated in  FIGS. 1-27 .
