Abstract:
A vending arrangement for computerized vending machines, retail displays, automated retail stores, utilizes a centralized, robotic gantry associated with companion modules for vending a plurality of selectable products. The modularized design enables deployment of half-sized or larger, full sized machines. The robotic gantry is deployed in a centralized module disposed adjacent display and inventory modules. Inventory modules can be fitted to both gantry sides, and doors can be fitted to the gantry front or rear. The gantry comprises an internal, vertically displaceable elevator utilizing a central conveyor for laterally, horizontally moving selected items from associated display and inventory positions to a vending position. Computerized software enables the display and vending functions, and controls elevator movement to dispense products from twin sides of the gantry by appropriately controlling the conveyor.

     BACKGROUND 
       [0002]    1. Field 
         [0003]    The present system relates generally to automated and modularized vending machines that can be custom deployed in diverse configurations. More specifically, the present system relates to automated vending systems utilizing an improved robotic dispensing module and associated inventory modules that can be assembled and configured to create diverse vending arrangements, with components linked together via a virtual integrated network. 
         [0004]    2. Description of the Related Art 
         [0005]    Numerous vending machines exist for selling or vending diverse products through an automated, or ‘self-service’ format. Vending reached popularity in the late 1800&#39;s with coin-operated devices dispensing diverse merchandise. More recently vending machines have evolved to include robotic dispensing components, and/or PCs and virtual interfaces. These new vending platforms have emerged in the marketplace under the popular descriptions “automated retail,” “interactive retail,” and/or “interactive retail displays.” Such vending machines may be deployed within a variety of commercial or public settings. They typically include illuminated displays that seek to offer convenient purchasing. 
         [0006]    In the vending arts, machines historically have a similar design and orientation that make them unable to easily change machine sizes and configurations, inventory storage sizes and product form factors without rebuilding or redesigning the machine. Typically machines are “one size fits all”. There are some models of traditional vending machines that allow additional inventory areas to be added on, but these models do not utilize a robotic dispensing unit to move the product from the shelf to the collection area and rely on gravity (drop) systems. Because of the expense of robotic delivery systems and the configuration of these systems, these machines have been constrained to serving one user at a time through one side of the machine. In addition the machines come in a single size format and two machines have to be stacked adjacently to expand site capacity. In more modern robotic machines, the size of the machines tends to be larger than traditional vending machines and units cannot be reduced based on the robotic architecture and production of the machine. In all of these machines, the robotic dispensing system is built as a continuation of the inventory system and cannot be easily separated. 
         [0007]    The present system introduces a preferred mechanism for dispensing items in a vending machine or automated retail store. It is preferably used in conjunction with an isolated and centralized robotic dispensing system that can support multiple inventory areas and technologies within those areas. The present system provides the ability to collect items delivered from a variety of inventory dispensing systems from multiple sides. It also provides the ability to deliver these collected items to users out of multiple sides of the machine allowing more than one person to simultaneously conduct transactions within the same machine, or to function with one or more inventory cabinets without any major modifications to the mechanism. 
         [0008]    There is great value in having a common mechanism that can handle receiving merchandise from multiple inventory cabinets with various types of inventory tray dispensing mechanisms. 
         [0009]    Being able to use multiple types of inventory tray mechanisms with a single dispensing system allows a greater range of possible inventory that can be dispensed. Specialized inventory trays can be customized to fit merchandise of varying form factors and still use the common centralized robotic dispensing system with reliability. This allows the machine to adapt and evolve over time without having to redesign the end dispensing system saving cost and development time. 
         [0010]    These various inventory areas can be used with the same dispensing system allowing a great deal of flexibility in how the machine is configured. A machine can be composed of inventory elements, display units and a central dispensing area “strung together” enabling the machine footprint to grow/contract depending on environmental constraints. Inventory solutions can be updated and reconfigured to work with the central dispensing mechanism without significant customization of the dispensing mechanism, allowing for rapid accommodation of new types and amounts of merchandise for purchase or promotion. 
         [0011]    This central dispensing system design allows greater reliability of dispensing by providing a uniform broader surface area (landing pad) for products to dispense. It also reduces axes of motion by 1 (e.g. X, Y, and Z reduces to Y and Z motion) by eliminating excess movement through inefficient placement of inventory and robotic components. Elimination of excess movement reduces potential points of failure and additional calibration and programming, in addition to increasing power efficiency and delivery speed. This design affords the ability to dispense out of multiple sides of the machine allowing more than one user to use the machine at the same time. 
         [0012]    It is thus desirable to provide a method and mechanism that enables a wide range of inventory to be dispensed to a user with a common end dispensing system. It is also desirable to be able to isolate this mechanism in a standalone structure that can be attached to one or more inventory areas. 
       SUMMARY 
       [0013]    The present system consists of a conveyor, product collection wings, elevator mechanism, and supports that make up a robotic gantry. In the present system&#39;s preferred configuration, it is connected to a series of physical merchandise displays, promotional/digital signage, automated mechanical/dispensing, and/or transactional modules that can be assembled and configured to create an automated retail store, vending unit, or interactive retail display of any size and link together via a virtual integrated network. The present system allows for a highly customizable vending machine of different sizes and configurations that can dispense a wide array of items all utilizing a common robotic dispensing module. 
         [0014]    In accordance with one aspect of the present system, there is a robotic elevator operated by one or more motors that delivers a landing platform to meet items that are located in various inventories. The elevator positions itself at a close height proximity that prevents items from being damaged as they are dispensed from their holding area onto the robotic platform. 
         [0015]    In accordance with another aspect of the present system, the platform consists of a conveyor that can rotate in either direction to move the collected item to a designated user collection area. 
         [0016]    In accordance with another aspect of the present system, the conveyor delivers the item into a secure designated collection area that consists of a space to receive the dispensed items and a method to secure the internal dispensing mechanism in order to prevent tampering by a user, or injury to the user. 
         [0017]    In accordance with another aspect of the present system, the inventory areas are attached to the centralized robotic dispensing mechanism. These inventory areas can vary in size to accommodate different product mixes but attach to the central robotic dispensing system in the same manner. 
         [0018]    In accordance with another aspect of the present system, the display areas can vary in size, configuration and appearance to fit the products or items being merchandised. 
         [0019]    This system and design improves the efficiency of dispensing items by allowing one or more inventory areas of various sizes to be attached to a centrally located and common robotic collection and dispensing system. Because of this design, there is no need for redundancy of expensive robotic components when increasing inventory size. By isolating the inventory retrieval and dispensing mechanism from the inventory storage area, a multitude of different inventory areas can be attached without the need to redesign this subcomponent when altering machine size or configuration. These inventory areas can employ various mechanisms that feed into the dispensing mechanism. These inventory areas can also alter to accommodate a wide range of items in quantity and size. 
         [0020]    The present system provides a common robotic dispensing system to service more than one user in parallel. By providing an isolated and centrally located mechanism, multiple users can engage with a system simultaneously. Purchased items are queued based on time of transaction and dispensed accordingly. This provides a great advantage by removing the constraint of one user at a machine at one time. This is a pronounced advantage in crowded or popular venues, where queues may form in front of machines. The dual-sided machine allows for almost double the users to be serviced in the same amount of time by providing two portals for transaction and product dispensing within a single machine platform. It also enables greater flexibility in merchandising/designing the machine in that each side of the machine can take on a different look/feel, but be accessed by the same robotic mechanism. 
         [0021]    The present system enables separation of the purchasing/transactional components of the vending platform with the dispensing components, allowing inventory and completion of the process to occur in a different location from the selection of merchandise and payment transaction. One such scenario: a physical space is inhabited by a central dispensing mechanism that attaches to adjacent inventory dispensing towers; users retrieve their purchases out of multiple sides of this mechanism after completing the transaction at screens. These screens can be integrated within this location or located remotely. 
         [0022]    This new centralized robotic vending mechanism increases the flexibility in dispensing capability in product size, shape, and orientation. In addition, it decreases the axes of motion and potential points of error by creating a more efficient mechanism and process of dispense. As a result, the machine&#39;s size, capacity and shape can change without duplication of expensive robotic components. This design also allows multiple users to simultaneously purchase items in the machine at two different parallel locations at the machine, while utilizing the same robotic dispensing mechanism. This doubles the service capacity of the machine. This also establishes a modular machine assembly convention whereby the robotic dispensing mechanisms are housed in one distinct section of the machine (the totem) and the inventory sections are separate segments that can affix to the totem to expand or contract depending on space and business considerations, without necessitating redesign of the machine&#39;s hardware or software. 
         [0023]    Objects of the present system are to provide a product vending machine, automated retail machine, or self-service machine where items are stored inside a secure area and delivered to a user upon a successful transaction in an automated manner. 
         [0024]    A basic object is to provide an improved design for product dispensing that cost effectively increases versatility, efficiency, and reliability of the system. This includes, improved product containment systems to increase product storage capacity, ease and efficiency of product handling, dispensing, structural integrity, modularity, customization, shipping/assembly, access and loading of the machine. 
         [0025]    Another basic object of the present system is to provide a more effective and flexible vending machine design that can be adapted for its deployment environment by reusing a common dispensing component. 
         [0026]    The present system provides a system and method to efficiently configure and deploy a vending system that accomplishes the following:

No. 12/806,862, entitled “Modular Vending with Centralized Robotic Gantry” filed Aug. 23, 2010, by coinventors Darrell Mockus, Mara Segal, and Russell Greenberg, that was based upon a prior pending U.S. Provisional Application Ser. No. 61/237,604 filed Aug. 27, 2009, and entitled “System And Method For Dispensing Items In An Automated Retail Store Or Other Self-Service System (Including Vending And Self-Service Check-Out Or Kiosk Platforms)”: by co-inventors Darrell Scott Mockus, Mara Segal and Russell Greenberg, and priority based on said application is claimed. 
         [0074]    With initial reference directed to  FIGS. 1A-1E  of the appended drawings, a robotized gantry  100  is adapted to be integrated into a multiple-module vending machine or automated retail store (see vending machine  200 ,  FIGS. 2A and 2B ). Gantry  100  comprises a rigid, upright frame consisting of an upper square portion  101 , supported by vertical upright C-Channel support beams  102  attached to a gantry base  110 . An internal elevator comprises a transverse conveyor  105  resting upon an elevator conveyor tray  107  within the gantry  100 . Conveyor  105  comprises a flexible sheet looped and entrained about a pair of spaced apart rollers  105 B that are journalled in the frame at  120  ( FIG. 1D ). The elevator is supported by two brackets  109  disposed on opposite ends of conveyor tray  107 . The elevator, and thus conveyor  105  and tray  107  can be raised or lowered using pulleys  103  ( FIG. 1A ) that are attached atop the vertical support beams  102  and which entrain 9 mm wide and 3605 mm long belts  104 . 
         [0075]    Preferably conveyor tray  107  has a pair of retractable, product collection wings  106  that open in response to wing hinge assembly  108  when the elevator is in place to collect items that are dispensed from inventory area(s) in modules placed on either side of the dispensing gantry  100 . Wings  106  span the distance between the conveyor and the inventory shelves caused by the necessary existence of the frame structure to support the conveyor elevator. 
         [0076]      FIGS. 1C and 1D  clarify how gantry components are driven. The conveyor belt  105  is driven by a conveyor stepper motor  111  that uses a 9 mm. wide belt  121  ( FIG. 1E ) to power a drive pulley connected to a roller bar  112  and feeds the conveyor belt around the conveyor rollers  105 B that are journalled at  120 . The flexible conveyor fabric is wrapped around the conveyor drive roller  112  and the rollers  105 B. 
         [0077]    The generally rectangular product collection wings  106  are disposed on either side of the conveyor  105  to direct selected products upon the conveyor to vend. The retractable wings  106  are actuated by the wing motor  113  ( 514   FIG. 5 ) connected to the wing hinge assembly  108  ( FIG. 1A ) which comprises a wing drive shaft ( 124   FIG. 1F ) that distributes power from the motor to a series of levers  114  and  115  that are connected to hinges  116  secured to the product collection wings  106 . As the motor turns from the closed position, the support levers  115  are pulled downwardly, causing the upper portion of the levers  115  to slide within stabilizer follower slots ( FIG. 1B ) in hinges  116 . This opens the collection wings  106  to a predetermined width that allows the conveyor  105  to collect products from inventory areas attached to either side of the central gantry dispensing assembly  100 . The motor can be reversed to close the product collection wings. 
         [0078]    The elevator motor  117  ( 507   FIG. 5 ) is connected to a pulley wheel and uses a 9 mm. wide belt to drive the elevator drive shaft  118  turning two pulleys  129  mounted on either side of the subassembly that drives the elevator belt  104  which loops around the top pulleys  103  thereby raising or lowering the elevator. After a product is collected from the inventory shelf, the elevator is aligned with the collection area compartment behind the collection area opening  204  ( FIG. 2A ) in the totem door  211  ( FIG. 2A ). 
         [0079]      FIG. 1E  provides additional reference for  FIGS. 1A through 1D  in relation to the mechanisms that drive the conveyor belt in the robotic gantry. Parts and components have been removed for clarity. In this view, the belt  121  that drives the pulley  122  connected to roller bar  112  is illustrated. The conveyor  105  is threaded under roller bar  112  and over auxiliary roller bars  123 . 
         [0080]      FIG. 1F  provides additional reference for  FIGS. 1A through 1D  in relation to the mechanisms that operate the product collection wings  106  in the robotic gantry. Parts and components have been removed for clarity. When motor  113  is actuated from a closed position, drive shaft  124  rotates causing levers  125  to rotate. This causes levers  127  that are connected to levers  125  to contract because of their connection to hinges  126 . These levers are connected to lever  115  at point  128  pulling down forcing the lever connection point to slide in the slot in hinge  116 . Crossbar  114  keeps the power distribution even. When the motor is reversed back to the starting position, the levers move in the opposite direction causing the product collection wings  106  to close. 
         [0081]      FIG. 1G  provides additional reference for  FIGS. 1A through 1D  in relation to the mechanisms that operate the elevator in the robotic gantry. Parts and components have been removed for clarity. Motor  117  is connected to pulley  130  which drives belt  131  connected to pulley  132 . Pulley  132  is affixed with two set screws driven into flat spots on elevator drive shaft  118 . A support  135  provides additional shaft support between the couplers. The shaft is connected at either end to couplers  119  that deliver power to the belt pulley mechanisms  129 . The couplers  119  each have two flex points that allow the gantry to compensate for any torque on the assembly. The couplers  119  are helical beam couplings that each have two sets of spiral slots, a feature that provides compensation for parallel misalignment, angular misalignment or axial motion issues by flexing to these forces while maintaining a connection on both ends without compromising the coupler integrity. This way, the machine will continue to operate even if the drive shaft gets pulled out of alignment due to natural forces attributed to the installation environment or through warping due to age and wear. This feature greatly increases the mechanism&#39;s ability to perform under structure strain and natural wear. Both ends of the elevator belt  104  are attached to clamp  136 . There is one clamp on each side of the gantry (only one side is visible in the diagram). These clamps are attached to supports  134 . This clamp pinches the ends each belt  104  and causes the gantry to be attached to a fixed point on the belt. As the pulley assemblies drive the elevator belt in either direction, the gantry raises or lowers the entire elevator assembly accordingly. Supports  109  keep the elevator platform level. The elevator tray has a hinge coupler support  133  that consists of a pin and a series of rubber O-rings that fit inside a shaft. This mechanism allows the tray to have some flexibility to compensate for irregular weight distribution of heavy products and natural torque that can occur because of the installation location of the machine and wear and tear on the components that will occur over time. This feature is assisted by the design where the supports only connect on one side of the gantry allowing for additional stress on the frame to occur without impeding the elevator. There is great advantage to having this flexibility built into the gantry mechanism as the inability to compensate for these common forces in automated retailing installations can cause the dispensing mechanism to fail. The alternative of providing a very rigid support structure is cost prohibitive and can add significant weight to the machine that in turn causes logistic issues. 
         [0082]    With additional reference directed to  FIGS. 2A and 2B , a vending machine constructed in accordance with the best mode of the invention has been generally designated by the reference numeral  200  ( FIG. 2A ). Much of the hardware details are explained in the aforementioned pending applications that have been incorporated by reference herein. Display module  210  can be attached with a hinge to an inventory area covered by control panel  211 , comprised of a rigid upright cabinet, or the module  210  can be mounted to a solid structure as a stand-alone retail display. The display module  210  forms a door hinged to an adjacent cabinet such as an inventory cabinet  212 A adjacent gantry  100  that is covered by control column  211 . 
         [0083]    A variety of door configurations known in the art can be employed. For example, the display doors can be smaller or larger, and they can be located on one or both sides of the control column  211 . The display doors can have multiple square, oval, circular, diamond-shaped, rectangular or any other geometrically shaped windows. Alternatively, the display area can have one large display window with shelves inside.

A USB connection connects the product weight sensor  484  such as Sartorius (part number FF03 VF3959) that is located in the collection area to determine the presence of a dispensed item. 
         [0096]      FIG. 5  illustrates a detailed power distribution arrangement  500 . Because of the various components needed, power has to be converted to different voltages and currents throughout the entire system. The system is wired so that it can run from standard 110 V.A.C. power used in North America. It can be converted to run from 220 V.A.C. for deployments where necessary. Power from line-in  455  supplied through plug  452  ( FIG. 4 ) powers a main junction box  453  with multiple outlets ( FIG. 4 ,  5 ) that powers UPS  454  which conditions source power, and outputs to computer  450  line  456 . Power is available to accessories through main junction box  453  and Ground-fault current interrupt AC line-in  455 . An additional AC outlet strip  501  such as Triplite&#39;s six position power strip (part number TLM606NC) powers LED lighting circuits  502  and a touch system  503 . Power is first converted to 5 volts to run the lighting board logic using a converter  540 . Another converter,  541 , converts the AC into 24 Volt power to run the lights and touch system. 
         [0097]    An open frame power supply  505  ( FIG. 5 ) provides 24 VDC, 6.3 A, at 150 watts. Power supply  505  powers Y-controller  506  such as the Arcus Advanced Motion Driver+Controller USB/RS485 (part number Arcus ACE-SDE), that connects to Y axis stepper motor  507  ( 117   FIGS. 1C &amp; 1D ). A suitable stepper  507  can be a Moons-brand stepper motor (part number Moons P/N 24HS5403-01N). Power supply  505  also connects to a conveyor controller  508 , which can be an Arcus-brand Advanced Motion Driver+Controller USB/RS485 (part number Arcus ACE-SDE), that connects to a conveyor stepper  509  ( 111  in  FIG. 1C  and  FIG. 1D ). A Moons-brand stepper motor (part number Moons P/N 24HS5403-01N) is suitable for stepper  509 . 
         [0098]    Power supply  505  ( FIG. 5 ) also powers dispenser controller  510 , dispenser door control  511 , and vending controller  512 . Controller  510  powers collection wing motor  514  ( 113   FIGS. 1C and 1D ) and door motor  515 . Motors  514  and  515  can be Canon-brand DC gear motors (part number 05S026-DG16). Controller  512  operates conveyor motors  516  such as Micro-Drives DC Gear Motor (Part Number M32P0264YSGT4). The logo space  201  ( FIG. 2 ) is illuminated by lighting  518  ( FIG. 5 ) powered by supply  505 . Supply  505  also powers LCD touch screen block  520  ( FIG. 5 ) such as a Kristel 22″ Widescreen (16:10) LCD Touch Monitor with USB connection for the touch panel. UPS  454  ( FIG. 5 ) also powers an AC outlet strip  522  that in turn powers a receipt printer power supply  523  such as Epson&#39;s 24 VDC power supply (part number PS-180) that energizes receipt printer  524  such as Epson&#39;s EU-T300 Thermal Printer, an audio power supply that powers audio amplifier  527  such a Happ Controls Kiosk 2-Channel Amplifier with enclosure (part number 49-5140-100), and a low voltage cell modem power supply  530  that runs cellular modem  531  such as Multitech&#39;s Verizon CDMA cellular modem (part number MTCBA-C-IP-N3-NAM).

         [0099]    Subroutine  600  ( FIG. 6 ) illustrates the preferred method of initializing the machine and inventory and dispensing system at system runtime. The process begins at step  601  when the system application is launched. Step  602  reads in and parses the lighting XML file  603 . The lighting file contains a sequence of lighting sequences to be performed for various user actions on the system such as selecting a product or category, adding to the virtual shopping bag and removing it from the shopping bag. These lighting sequences dictate both the onscreen coloring of products in the virtual display and the lighting of products in the physical display. These values are cached in local memory as an application variable. Step  604  checks if there are any fatal errors. Fatal errors are ones that prevent the system from allowing a user to complete a transaction. All errors are logged using the reporting and logging system  303  ( FIG. 3 ). Non-fatal errors are noted in the log file so they can be examined later to correct the issue. If the error is fatal, the process goes to step  605  where the user is notified of an error and given customer support information and an alert notification is sent out to the notification system  303  ( FIG. 3 ). The system is placed in an idle state where the touch screen will display a message noting that the machine is currently not in service. The system will attempt to recover in step  606  by attempting to start the application process again and reinitialize the system. If there are no fatal errors, the process continues to step  607  that reads in and parses the planogram file  608 . The planogram file contains the product identification number, or item identification number, a product name and a Boolean value if it is active or not for each display slot number. These values are cached in local memory as an application variable. Step  609  checks if there are any fatal errors. If there are fatal errors, it routes to step  605 , otherwise the process continues at step  610 . Step  610  reads in all of the inventory XML files. These files instruct the system on what inventory cabinets are attached to the machine and what inventory is in what inventory slots. Each inventory slot is designated by the cabinet it is located in, the shelf it is on, the size of the inventory slot and the motors that drive the dispensing mechanism. Using this information, the application can determine the shelf location (height). The XML file information is cached and then accessed during product dispensing to guide the robotic gantry elevator to the correct shelf height to collect a product. 
         [0100]    The dispensing motor information is used by the dispenser control to turn on the motor that dispenses the product until a mechanical switch is activated determining the product has been dispensed to the gantry elevator. Because of the centralized layout of the robotic gantry, it does not matter which inventory system is connected or even what side from which the product is being dispensed. It only matters what shelf the product is on so the elevator can move to the correct height to collect the product. Step  610  reads in all of the screen templates  611  that determine the layout of the visual selection interface. Step  612  checks if there are any fatal errors. If there are fatal errors, it routes to step  605 , otherwise the process continues at step  613 . Step  613  reads in all of the screen templates  611  that determine the layout of the user interface and all of the screen asset files  614  associated with the screen templates  611 . 
         [0101]    These asset files can be images or extended markup files that represent buttons, header banners graphics that fit into header areas, directions or instructions that are displayed in designated areas, image map files that determine which area on an image corresponds represents which area on the physical facade or images representing the physical façade. These assets are cached into local memory in the application. Step  615  checks if there are any fatal errors. If there are fatal errors, it routes to step  605 , otherwise the process continues at step  616 . Step  616  reads and parses the product catalog files  617 . The product catalog stores all of information, graphics, specifications, prices and rich media elements (e.g. video, audio, etc.) for each item or product in the system. Each element is organized according to its identification number. These elements can be stored in a database or organized in a file folder system. These items are cached in application memory. Step  618  checks if there are any fatal errors. If there are fatal errors, it routes to step  605 , otherwise the process continues at step  619 . Step  619  reads in all of the system audio files  620  and the file that the stores the actions with which each audio file is associated. Audio files can be of any format, compressed or uncompressed such as WAV, AIFF, MPEG, etc. An XML file stores the name of the application event and the sound file name and location. Step  621  checks if there are any fatal errors. If there are fatal errors, it routes to step  905 , otherwise the process continues at step  622 . Step  622  does a system wide hardware check by communicating with the system peripherals and controllers  302  and  308  ( FIG. 3 ). Step  623  checks if there are any fatal errors. If there are fatal errors, it routes to step  605 , otherwise the process continues at step  624 . Step  624  launches the application display on the touch screen interface. The system then waits for user input  625 . 
         [0102]    Subroutine  700  ( FIG. 7 ) illustrates the preferred runtime method the machine uses to dispense items to an end user during a user session. The process begins at step  701  after a user completed a transaction that purchases the merchandise about to be vended. This process assumes that a separate process has already checked that the inventory is available for vending and it has been paid for. The routine is passed a list of items to be dispensed. For items that have multiple quantities, each item is listed as a separate item. Step  702  reads this list into the process memory. Step  703  determines if the dispensing system is busy processing another request. If the dispensing system is busy for any reason, step  704  pings the resource until it is free and then directs the process to step  708  where the first (or next) item in the list is read. Step  705  is a timer that monitors step  704  to determine if the wait for the resource times out to a preset time. If it does time out, the process is considered to have an error and it directs control to step  706  that sends out an alert using the notification system designated by  303  ( FIG. 3 ). Step  707  attempts the recovery of the system by running any preprogrammed diagnostics and self repairing routines that check and restart power and communication links to the system. If the system cannot automatically recover, the machines goes into an idle state and a message is displayed on the main screen indicating the machine is currently out of service preventing users from using the system. If the system resources are free, step  708  reads the next item to be vended from the list and retrieves its associative information into memory. This information was originally loaded into the system as the inventory XML file  611  ( FIG. 6 ) read into memory in step  610 . The item, or product id is used to retrieve this information. Information associated with the identification number includes the item&#39;s location in the inventory system (shelf height and corresponding elevator position represented as the position the elevator needs to be in to properly collect the dispensed product), the dispensing motors associated with vending the item from the inventory shelf and item details such as its name to prompt the user, and its weight and dimensions which are used in conjunction with the product weight sensor  484  ( FIG. 6 ) to determine a successful vend. 
         [0103]    Step  709  uses this information to move the elevator tray assembly  107  ( FIG. 1A ) to the correct shelf height for the current item being vended. The elevator height is determined by preset position values that tell the stepper motor where to position itself on the vertical aspect of the gantry. The stepper motor has an encoder that communicates with the controller to verify the position. This combination of hardware allows the software to set a height value and have the stepper motor and the stepper controller ensure the correct position is attained. If there is a detectable error with the elevator mechanics, an error message is generated and sent out by step  706 . Step  707  will again try to recover if possible. If the elevator assembly reaches the correct height and position as designated by the product information record, the product collection wings  106  ( FIGS. 1A and 1B ) are expanded to create an extended landing area that will catch products coming off the inventory trays  213  ( FIG. 2 ). If an error in this process is detected, an error message is generated and step  706  will send out an alert. Otherwise, if the elevator is in position and the production collection wings are extended, step  711  will use the information retrieved in the product record to activate the motor(s) associated with that item of inventory. A mechanical switch is used to indicate that the motor has revolved enough times to properly dispense the product or item off the shelf at which point it falls on to the product collection wings and into the conveyor  105  ( FIGS. 1A and 1B ). Errors are again detected if present and routed to the notification system in step  706 . Step  712  retracts the product collection wings so the elevator can freely move up and down in the dispensing assembly. This step also assists in positioning the product on the conveyor where it can be delivered to the user later in the process. Any detected errors in this step are routed to step  706 . If there are no errors, step  713  moved the elevator gantry to the user collection area. The movement of the elevator mechanically opens up the product collection area by activating levers that open the top and back of the area. If no errors are detected, step  714  notes which control activated the dispensing process. This is only relevant when the machine is configured for dual sided vending (see  FIGS. 9 and 11 ). Step  715  then spins the conveyor in the direction of the user that initiated the dispensing process. If no errors were detected, step  716  repositions the elevator that reverses the mechanical operation that opened the back of the collection area and closed it sealing off the internal components of the machine from the user. If no errors were detected, step  717  turns on the lights in the collection area  204  ( FIG. 2 ) and opens the exterior collection area door. Step  718  prompts the user on the screen  202  ( FIG. 2 ) to collect their product. Step  719  monitors signals from the product weight sensor  484  ( FIG. 4 ) records the weight and matches it against the product weight information stored in the inventory XML file  611  ( FIG. 6 ). This sensor could also be a motion or light curtain sensor. If the item was not removed for a preset amount of time, the user is prompted again to collect their item in step  718 . If user does not collect their product after a set number of attempts, an error is generated. If the sensor determines the user has removed their item, the process continues to step  720  where the exterior door is closed and the product collection area lights are turned off. The system again monitors for any mechanical errors in this process (line to step  706  not shown). Step  721  determines if there are any additional items in the list of items to be vended. If there are additional items to be vended, the process routes back to step  703  where it begins again for the next item. If there are no more items to be vended, the process ends at step  722 . 
         [0104]    With reference directed to  FIG. 8 , an alternative vending machine  800  constructed in accordance with the best mode of the invention incorporates a variant on the display module designated as  210  in  FIG. 2A . In this version the display module has a plurality of generally square product viewing areas  801  that present an alternative display, different from the diamond and circle display windows designated at  206  and  207  respectively in  FIG. 2A . 
         [0105]    With reference directed to  FIG. 9 , an alternative  900  ( FIG. 9 ) shows an alternative configuration of the machine where it has been outfitted to dispense merchandise out of both the front and back of the machine. This machine has display modules  210  affixed to both sides of the inventory cabinet  212 . It also has a vertical control column  211  affixed to both sides of the central robotic gantry  100 . This configuration allows the unit to serve two people at the same time. 
         [0106]    With reference directed to  FIG. 10 , alternative machine  1000  represents a similar configuration but with only one inventory cabinet  212  and display module  210 . These are once again attached to the common centralized robotic dispensing gantry  100 . In this configuration a simple metal plate  1001  (not shown) cut the size of the dispensing system tower is affixed to the side where the inventory cabinet was attached in  FIG. 8  using the same bolts to secure the system.
