     FIELD 
     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 improved inventory storage and dispensing modules that can be assembled and configured by hand (without tools) and on-site, to support diverse product ranges, including small product samples and large, odd-sized, odd-shaped, light and heavy items, with components linked together via a virtual integrated network. 
     BACKGROUND 
     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 descriptions such as “automated retail,” “interactive retail,” and/or “interactive retail displays.” Such vending machines may be deployed within a variety of commercial or public settings. 
     In the vending arts, machines historically have a similar design and orientation that make it difficult or impossible to change machine sizes and configurations, inventory storage sizes and product form factors without rebuilding or redesigning the machine, or components contained therein. Typically machines are “one size fits all” or are customized for a fixed set of product sizes and dimensions. In other words, they are designed to a limiting group of specifications and lack the flexibility and re-configurability to accommodate drastic changes in inventory form factors, or a wide universe of products including very small thin items, or items with variable surfaces (protruding, bulging zones, irregular forms) without secondary packaging. 
     There are some models of traditional vending machines that have some flexibility to support the changing of inventory to different sized items, but they have limits when it comes to non-square or non-rectangle products, thin products or those that are much greater in one size dimension versus the others. In addition these predecessor systems generally allow objects to be dispensed in only 1-2 orientations (right side up, or upside down) limiting the capability to stock inventory and inventory shelves with maximum efficiency. 
     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 reconfigure these inventory and storage components in the field in a short period of time limiting machine downtime. 
     SUMMARY 
     The present system consists of a number of slats that make up a conveyor of any size, a number of dividers suitable to contain what is being dispensed, a housing, motor, pulleys, gears and a drive belt. In a preferred configuration, numerous inventory modules of various configurations are installed in 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 system that can accommodate a wide array of items all utilizing a common inventory storage and dispensing model design. 
     In accordance with one aspect of the present system, the design utilizes common inexpensive conveyor pieces (slats), dividers, gears, motors, pulleys, belts and fasteners to adjust to a wide range of configurations. 
     In accordance with another aspect of the present system, the conveyor slats used to form the conveyor can be created in any length. 
     In accordance with another aspect of the present system, the dividers can be placed at any distance apart within the constraints of one divider per slat and no greater than the entire length of the conveyor. 
     In accordance with another aspect of the present system, housings can be created to hold and contain as many conveyors as needed to hold items designated for dispensing. 
     In accordance with another aspect of the present system, housings can vary in density and accommodate as many levels as can fit within the unit&#39;s enclosure. 
     In accordance with another aspect of the present system, a simple plug-in relationship between conveyor parts is established for reconfiguration by hand versus a tool. 
     In accordance with another aspect of the present system, a unique forked ramp assists the transfer of items from the inventory storage mechanism to a collection or delivery area. This forked ramp reduces errors in product transfer by matching the angle of the ramp with the product divider. This mechanism allows dispensing items to smoothly transfer from a horizontal to an angled surface. 
     In accordance with another aspect of the present system, an inexpensive universal system of inventory parts has been developed to work in a modular configuration to assemble an inventory system. 
     The present system and design improves the efficiency of dispensing items by allowing a single design consisting of common parts to accommodate a wide range of product sizes and form factors. It also improves the reliability of dispensing items by accommodating for human error in stocking with mechanical sensors to deal with incorrectly spaced dividers and housing walls to contain items that may shift in position. Inventory storage efficiency is also improved by enabling items to be oriented in multiple directions versus just upright or inverted. This system and design cuts down on excess packaging waste by eliminating the need to repackage most odd-sized items. 
     The present system and design gives greater flexibility to the merchandising and storage capability of an automated retail machine, enabling a range of merchandise and product storage density to occur within the confines of an existing enclosure. Examples of this could be a machine stocked full of sample sizes vs. full sizes, or a mixture of products that may change frequently. The inventory system is able to accommodate these reconfigurations without any tools, reengineering, or significant reprograming of the system. The shelves are able to communicate their location by where the data and power connection is made. As the shelves are inserted into a rack, they make a power and data connection at that level. Depending on where this connection is made, the application can recognize and note the location. A series of connection points exist for possible shelve locations. 
     The present system provides a common inventory and storage design that can be configured in the field without additional tools or highly specialized labor. This facet provides a great advantage by decreasing additional materials, labor and the amount of components that need to be manufactured and assembled to create an inventory lane. 
     This is a pronounced advantage in both machine design and manufacturing given the retail marketplace is dynamic and the machine will be able to inexpensively respond to changing merchandising needs. In addition this is a pronounced advantage in supply chain operations given that more merchandise may be stocked in the machine due to optimization of orientation and density, and flexibility to accommodate multiple rows of popular items. In addition, with this design more merchandise can be accommodated without sacrificing the consumer experience given the inventory system can be housed behind a static product display. In addition, the capability to house more merchandise can decrease fulfillment trips and costs associated. In addition, this is a pronounced advantage in system operations and maintainability by decreasing the amount of specialized labor and tools necessary to reconfigure a machine in the field. 
     This new inventory storage and dispensing component design increases the flexibility in dispensing capability in product size, shape, and orientation. In addition, it decreases the time needed to reconfigure a system to dispense inventory of a different form factor. 
     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. 
     A basic object is to provide an improved design for product storage and dispensing that cost effectively increases versatility, efficiency, and reliability of the system while decreasing specialized support or tools to alter. 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. 
     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. 
     The present system provides a system and method to efficiently configure and deploy a vending system that accomplishes the following:
         a) To provide a system design that can efficiently and effectively dispense a wide range of items (various sizes, shapes and types) in an automated (self-service) platform.   b) To optimize the inventory storage space inside of an automated retail machine, vending machine or other type of self-service machine.   c) To provide a design for a single inventory storage and dispensing system to support a wide range of inventory in a flexible and easily configurable/alterable manner.   d) To provide a cost-effective inventory system design that increases the efficiency of product delivery by opening multiple transaction portals in a machine that utilizes the same centralized mechanism.   e) To provide an inventory system design that can accommodate very thin, standard, odd-shaped and variable sized inventory with high reliability, in variable densities and without secondary packaging.   f) To provide a system design that can optimize inventory storage density by providing the capability for products to be oriented in any way that enables more products to fit into storage based on popularity or business need.   g) To provide an intuitive system design that enables laypeople to reconfigure the inventory system with minimal training and without tools in order to update inventory storage.   h) To provide an inventory system design that increases the amount of flexibility in terms of product form factors and density of certain form factors in response to changing inventory needs in retail.   i) To provide an inexpensive and simplistic inventory system for automated retail by designing a system of common reusable parts.   j) To provide greater reliability in inventory dispensing in automated retail/vending platforms by creating an integrating forked ramp between the inventory and robotics dispenser.   k) To provide a reliable method to dispense a wide array of product samples within a vending or automated retail machine.   l) To provide a flexible inventory system design for automated retail and vending that enables accommodation of a broader range of form factors and to determine the necessary configuration to respond to these form factors of the system once deployed in the field.       

     These and other objects and advantages of the present system, along with features of novelty appurtenant thereto, will appear or become apparent in the course of the following descriptive sections.

     DETAILED DESCRIPTION 
     The present system introduces a preferred mechanism for storing and 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 capability to handle inventory of a wide range of form factors in size and shape, in a wide range of configurations. It also provides the ability to easily change the inventory configuration without any special tools quickly, efficiently and inexpensively. 
     There is great value in having a flexible inventory storage and dispensing mechanism that is easily reconfigured in the field by hand and with a standardized set of inexpensive parts. Some of the value adds include a wider range of products that can be accommodated without system redesign, decrease of development risks, decrease in costs associated with changes in merchandising and far fewer limits to merchandise/merchandising. 
     In addition, the re-use of components to build and configure the inventory system lowers the amount of pieces that have to be manufactured, distributed and stored. Inventory trays can be configured to fit merchandise of varying form factors and still use common pieces without any special tools or new parts saving cost and configuration time. 
     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. 
     The flexibility in the inventory system also enables products to be oriented in the most efficient direction in order to increase the density of merchandise and optimize efficiency in the supply chain (hypothetically decreasing the amount of stocking trips to the machine given greater capability to accommodate inventory units). In addition, the flexibility of the inventory system permits items of greater popularity to be stocked at a greater density than less popular items. 
     The importance of increasing the flexibility and field-based reconfigurability of the system by a layperson is that the technology is more capable of handling the quick changes that occur in retail merchandising within discretionary, or trend areas. In other words, the inventory system is able to change with retail dynamics and facilitate merchandising the most popular products without limitations imposed by existing inventory systems on the market today. 
     The inventory system is flexible enough to accommodate a machine full of what has been designated by brand manufacturers as a “product sample or sachet or trial size” of a product. Typically this unit will come in two form factors, a thin foil packaged sachet, or a vial mounted on a small piece of cardboard. Other form factors could include small cylinders or boxes. The inventory system accommodates a wide universe of samples and full size products. The machine could also be reconfigured to accommodate all sample sizes, or all full sizes of the products (as long as the full sizes met the size requirements). 
     In addition, due to the robust and flexible divider design and connection with the robotics system, items that are odd-sized will typically not necessitate secondary packaging. The system goes further than existing inventory offerings to accommodate odd, bulky, squishy, irregularly surfaced or weighted items without hypothetically requiring secondary packaging (boxing) of these items.

     With initial reference directed to  FIGS. 1A-1I  of the appended drawings, a inventory storage and dispensing module  100  is adapted to be integrated into a vending machine or automated retail store. 
     A housing  101  contains a conveyor  102  that is driven by motor  103 . The motor  103  drives the conveyor  102  towards ramp  104  that facilitates the delivery of items stored on the conveyor  102 . 
       FIG. 1B  shows an isometric exploded view of the base inventory module. Conveyor  102  is made up of a series of conveyor pieces  105  (see  FIG. 1D ) and divider pieces  106  (see  FIG. 1E ). The conveyor  102  slides on smooth rub strips  107  that reduce friction. These are mounted to conveyor support  108  that sits in housing  101  to provide support for conveyor  102 . The conveyor  102  is driven by motor  103  that is mounted in motor bracket  109  and connected directly to pulley  110 . This pulley connects to the drive pulley  111  via belt  112 . A shaft  113  goes through pulley  111  and drive gear  114  and rides on two press-fit bearings  123 . The wiring for the motor  103  and stop switch  122  is routed out the housing through grommet  115  through E clips  116  and  117  secured to the shaft  113 . The other end of the conveyor  102  rides on another gear  114 . An optional hook  118  that is part of the housing  101  that will insert into a slot on the tray shelf  171  (see  FIG. 1I ) to secure it. These hooks  118  can be added or removed during manufacturing. Hole  125  provides an additional or alternative way to fasten the dispensing module  100  or lane to a tray. A screw such as a IA″ is inserted through the hole into a threaded component on the tray  171  holding the dispensing module  100  in place. There is an additional hole (not pictured) towards the back of the dispensing module  100  that secures the other end of the dispensing module  100 . Shaft  119  is inserted through the gear and rides on two press-ft bearings  124  pressed into housing  101  and secured by E clips  120  and  121 . Stop switch  122  is mounted to housing  101 . 
       FIG. 1C  shows a side view of the base inventory dispensing module  100 . In this view, the flag post of part  106  ( FIG. 1E ) can be seen activating stop switch  122  which sends the signal that the conveyor has advanced enough to properly dispense a product down ramp  104 . 
       FIG. 1D  shows a number of detailed illustrations of conveyor piece  105  ( FIG. 1B ) from different angles.  105 A is an angled elevation of the conveyor piece. Slots  130  exist at either side of the conveyor piece allowing the stop flag tabs  141  of the divider part  106  ( FIG. 1E ) to extend though the conveyor piece  105 . A slot  131  receives the divider connection tab  142  ( FIG. 1E ). Male tab  132  and female tabs  133  allow conveyor pieces  105  to be strung together in any length. This flexibility allows the conveyor  102  to grow or contract to any size required.  105 B is a bottom elevation of the conveyor piece  105 . In this view, the alignment of the male connection tabs  132  can be seen in relation to the female connection tabs  133 .  105 C shows the side elevation of the conveyor piece  105  and the vertical alignment of male connection tabs  132  with female connection tabs  133 .  105 D shows a cross-sectional side view of the conveyor piece  105 . 
       FIG. 1E  shows a number of detailed illustrations of divider piece  106  ( FIG. 1B ) from different angles. The divider piece  106  fits into conveyor piece  105  ( FIG. 1D ) providing the ability to create a dividing separation at any distance in increments of the conveyor depth. This feature provides great flexibility in adjusting the conveyor  102  on-site in the field to accommodate different inventory. This process requires no tools and can be accomplished while the conveyor is installed in the machine. Fork tabs  140  facilitate the handoff from the conveyor  102  to a receiving area. The fork tabs  140  pass through the ramp  104  ( FIGS. 1A and 1B ) to provide a smooth item handoff. The motor stop flag tabs  141  fit through slots  130  ( FIG. 1D ) in the conveyor piece  105 . These tabs  141  activate the stop motor switch  122  ( FIG. 1C ) as they pass over the switch  122 . This signals the application that the conveyor  102  has dispensed one item and to stop rotating the motor  103 . Connection tab  142  fits into slot  131  in the conveyor piece ( FIG. 1D ) securing the divider  106  to the conveyor piece  105 . The connection tab  142  includes two outwardly biased prongs each with a first ramped surface to introduce the tab  142  into the slot  130  and a second ramped surface to releasably retain the tab  142  in the slot  13 . The second ramped surface is preferably configured at a steeper angle to the longitude axis of the tab  142  than the first ramped surface. 
       FIG. 1F  shows an alternate configuration of the conveyor  102  illustrated in  FIGS. 1A through 1E . Here, the majority of the same components are used to create a dispensing module  150  that can hold larger products. By using a different motor bracket  156 , axels  154  and  155  and housing  151 , the same inventory design can be adjusted to handle items of any size (illustrated in  FIG. 1G ). Conveyors  102  fit inside a larger housing  151 . A wider forked ramp  152  helps guide dispensed products into a collection area. 
       FIG. 1G  shows an isometric exploded view of the dispensing module  150  in  FIG. 1F . This figure illustrates the similar components used and the ones that are modified to fit the larger housing  151 . There is a larger mounting bracket  153  that supports the conveyor. A larger shaft  154  houses two gears  114  that drive the conveyors  102 . A larger shaft  155  holds the gears  114  that secure the other ends of the conveyors. A longer motor bracket  156  positions the motor  103  at the right position to drive the assembly. 
       FIG. 1H  shows another alternate configuration of the inventory assembly. A different housing  161  is used that contain two conveyors  102  that are side by side. A different fork ramp  162  is used that fits the housing. 
       FIG. 1I  shows several conveyor lanes, i.e., dispensing modules  100  and  150  mounted on a shelf or inventory tray  171  in a support structure  170 . Conveyor lanes  100  and  150  are shown affixed to an inventory tray  171 , which are affixed to C-Channel upright side supports  172 . A rail support  173  spans the C-Channel upright side support  172  and fits into holes  174  and notches  175 . (rail support on other side not shown). The rail supports  173  can be placed in any of the holes and notches so they shelves can adjust to any height without any tools. 
     With additional reference directed to  FIGS. 2A and 2B , a vending machine constructed in accordance with the best mode of the present system 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  230  that is covered by control panel  211 . 
     A variety of door configurations can be employed. For example, the display modules  210  can be smaller or larger, and they can be located on one or both sides of the control panel  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 customizable, lighted logo area  201  ( FIG. 2A ) is disposed at the top of control panel  211 . Touch screen display  202  is located below area  201 . Panel  203  locates the machine payment system, coin acceptor machine or the like. Additionally panel  203  can secure a receipt printer, keypad, headphone jack, fingerprint scanner or other access device. The product retrieval area  204  is disposed beneath the panel  203  in a conventional collection area compartment (not shown). A key lock  205 , which can be mechanical or electrical such as a punch-key lock, is disposed beneath the face of the display module  210 . One or more motion sensors  214  are disposed within smaller display tubes within the display module  210  interior. A plurality of generally circular product viewing areas  207  and a plurality of generally diamond shaped viewing areas  206  are defined upon the outer the face of the casing  208  that are aligned with internal display tubes behind the product viewing surface areas, though the shape of the viewing areas may alter with various merchandising concepts. However, the convention of framing merchandising offerings is consistent to enable intuitive interfacing whether a physical or virtual representation of the merchandise display. An exterior antenna  209  connects to a wireless modem inside the machine providing connectivity. Inventory shelves  213  may be mounted in the inventory cabinet  212 . These inventory shelves  213  may contain any mechanism such as the dispensing modules  100  and  150  discussed above or other conveyors or spiral vending systems as long as they can push a product off the edge of the inventory tray. 
     Speakers  215  are mounted in the panel  211 . A camera  216  capable of capturing video and still images is also mounted in the panel  211 . The machine components are set on casters  217  with feet that can be retracted for moving or lowered to position a machine in a deployed location. 
       FIG. 2B  shows a standard configuration of the assembly. The robotized modular gantry  230  is shown connected to an inventory cabinet  212 A by bolting the upright C-Channel structures  232  of the modular gantry  230  to upright C-Channel beams  219  which are then affixed to the upright C-Channel structures  220  of the inventory cabinet  212 A using additional bolts. Power and controls are routed to the modular gantry  230  via a wiring harness (not depicted) located on the bottom of the modular gantry  230 . The CPU and power supplies (detailed in  FIGS. 4 and 5 ) are located in the bottom of the main inventory cabinet that is attached to a modular gantry  230 . A second inventory cabinet  2128  can also be attached to the other side of the robotized modular gantry  230  using the same method of bolting the upright supports of the inventory cabinets  220  and the upright supports  232  of the gantry  230  to a common upright C-Channel support  219 . 
     Display modules  210  can be attached to the inventory cabinets via a piano hinge  218  running the full height of the door. The necessary electrical and control wiring connects via a wiring harness  221  located on the interior of the inventory cabinet near the hinge connection.

The necessary electrical and control wiring connect to a wiring harness located in the interior of the control panel  211  (wiring harness not depicted). 
     With primary reference directed to  FIG. 3 , a system consisting of a plurality of automated retail machines connected via a data connection to a centralized, backend operations center system has been designated by the reference numeral  300 . At least one automated retail machine  301  is deployed in a physical environment accessible by a consumer who can interact with the machine  301  directly. There can be any number of machines  301 , all connected to a single, remote logical operations center  330  via the Internet  320  (or a private network). The operations center  330  can physically reside in a number of locations to meet redundancy and scaling requirements. 
     The machine software is composed of a number of segments that all work in concert to provide an integrated system. Logical area  302  provides the interface to deal with all of the machine&#39;s peripherals such as sensors, keypads, printers and touch screen. Area  303  handles the monitoring of the machine and the notifications the machine provides to administrative users when their attention is required. Area  304  controls the reporting and logging on the machine. All events on the machine are logged and recorded so they can be analyzed later for marketing, sales and troubleshooting analysis. Logical area  305  is responsible for handling the machine&#39;s lighting controls. 
     Logical area  306  is the Inventory Management application. It allows administrative users on location to manage the inventory. This includes restocking the machine with replacement merchandise and changing the merchandise that is sold inside the machine. Administrative users can set the location of stored merchandise and the quantity. 
     Logical area  307  is the retail store application. It is the primary area that consumers use to interface with the system. Logical area  308  handles the controls required to physically dispense items that are purchased on the machine or physically dispense samples that are requested by a consumer. This area reads the data files that tell the machine how many and what types of inventory systems are connected to the machine. Logical area  309  controls the inventory management system allowing authorized administrative users to configure and manage the physical inventory in the machine. Area  310  controls the payment processing on the machine. It manages the communication from the machine to external systems that authorize and process payments made on the machine. Area  311  is an administrative system that allows an authorized user to manage the content on the machine. This logical area handles the virtual administrative user interface described previously. The content can consist of text, images, video and any configuration files that determine the user&#39;s interaction with the machine. 
     The latter applications interface with the system through an application layer designated in  FIG. 3  by the reference numeral  312 . This application layer  312  handles the communication between all of these routines and the computer&#39;s operating system  313 . Layer  312  provides security and lower level messaging capabilities. It also provides stability in monitoring the processes, ensuring they are active and properly functioning. Logical area  331  is the user database repository that resides in the operations center  330 . This repository is responsible for storing all of the registered user data that is described in the following figures. It is logically a single repository but physically can represent numerous hardware machines that run an integrated database. The campaign and promotions database and repository  332  stores all of the sales, promotions, specials, campaigns and deals that are executed on the system. Both of these databases directly interface with the real-time management system  333  that handles real-time requests described in later figures. Logical area  334  aggregates data across all of the databases and data repositories to perform inventory and sales reporting. The marketing management system  335  is used by administrative marketing personnel to manage the marketing messaging that occurs on the system; messages are deployed either to machines or to any ecommerce or digital portals. Logical area  336  monitors the deployed machines described in  FIG. 2 , and provides the tools to observe current status, troubleshoot errors and make remote fixes. Logical area  337  represents the general user interface portion of the system. This area has web tools that allow users to manage their profiles and purchase products, items and services. The content repository database  338  contains all of the content displayed on the machines and in the web portal. Logical area  339  is an aggregate of current and historical sales and usage databases comprised of the logs and reports produced by all of the machines in the field and the web portals.

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. 
       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 ( FIGS. 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. 
     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 . 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 . A Moons-brand stepper motor (part number Moons P/N 24HS5403-01N) is suitable for stepper  509 . 
     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  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). A proximity sensor  214  ( FIG. 2A ) such as a Digi Watchport/D part number 301-1146-01 is connected to the CPU  450 .  532  is a door sensor and actuator such as Hamlin&#39;s position and movement sensor (part 59125) and actuator (part 57125) which are connected to the CPU  450 . 
     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. 
     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 . 
     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 . 
     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. 
     Step  709  uses this information to move the elevator tray assembly of the gantry  230  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 are expanded to create an extended landing area that will catch products coming off the inventory trays  213  ( FIG. 2A ). 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. 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. 2A ) to collect their product. Step  719  monitors signals from the product weight sensor  484  ( FIG. 4 ) and 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 . 
     With reference directed to  FIG. 8 , an alternative vending machine  800  constructed in accordance with the best mode of the present system 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 . 
     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 panel  211  affixed to both sides of the central robotic gantry  230 . This configuration allows the unit to serve two people at the same time. 
     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  230 . 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. 
     With reference directed to  FIG. 11 , another configuration of a vending machine  1100  utilizes the centralized robotic dispensing gantry  230  with one inventory cabinet and two display modules  210  and two vertical control panels  211 . As in  FIG. 9 , this configuration allows for two users to simultaneously interact with the machine while using only one robotic dispensing mechanism and sharing a common inventory cabinet. 
     It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims.
