DETAILED DESCRIPTION OF THE INVENTION

(17) Autonomous devices, systems and/or methods may perform one or more tasks without continuous outside control and/or intervention. An autonomous mobile robot, for example, may receive instructions to perform a certain task at a certain location. The mobile robot may subsequently determine and perform the operation(s) necessary to move to the location and/or complete the task based on, for example, its current location, surrounding obstacles, its operating environment, the type of task to be performed, etc. Such autonomous devices, systems and/or methods may also adapt to unknown, new and/or changing operating environments without additional outside control and/or intervention.

(18) Autonomous devices, systems and/or methods may be fully autonomous or semi-autonomous. The term fully autonomous is used to describe a device, system and/or method that may perform one or more tasks without, for example, any outside control and/or intervention. A fully autonomous mobile robot, for example, may perform a task without receiving instructions (e.g., vectors, commands, etc.) from a human operator during performance of the task. The term semi-autonomous is used to describe a device, system and/or method that may perform one or more tasks without, for example, continuous outside control. A semi-autonomous mobile robot, for example, may perform a task utilizing one or more periodic instructions from a human operator that bound and/or qualify the performance of the task. The instructions, for example, may provide an updated location of where the task is to be performed, identify an unknown obstacle, control the scope of the task, control when the task should be performed, etc.

(19) FIG. 1 illustrates an electro-mechanical mobile device 20 (e.g., an autonomous mobile robot) autonomously performing a task of loading one or more articles 22, 24, 26 and 28 onto one or more support surfaces 30, 32 and 34, where these articles may have different (or similar) shapes, sizes, weights, etc. Examples of articles include boxes, crates, containers, packages, barrels, canisters, luggage, chests, and amorphous bags, sacks and other such objects. Other examples of articles include electronic and/or mechanical devices and equipment, etc. Examples of support surfaces include pallets, cargo bay floors, warehouse floors, truck beds, ship hold floors, etc. Other examples of support surfaces include interior surfaces of support containers, boxes and the like in which the articles may be placed and subsequently transported and/or stored. The present invention of course is not limited to any particular article and/or support surface type or configuration.

(20) Briefly, the mobile device 20 may load one or more of the articles 22, 24, 26 and 28 onto a first of the support surfaces (e.g., the transport pallet 30), for example, by gathering the articles from one or more respective source pallets 36, 38, 40 and 42 and arranging the gathered articles onto the first support surface 30. Each of the source pallets 36, 38, 40 and 42 is located at a respective article pickup location, and may support (e.g., hold) similar types of articles; e.g., the source pallet 36 supports the articles 28, the source pallet 38 supports the articles 26, etc. Each of the support surfaces 30, 32 and 34 is located at a respective support surface location and may support one or more different types of articles. The articles loaded onto the first support surface 30 may be selected based on, for example, a destination of the first support surface, intended (e.g., medical, culinary, warfare/combat, humanitarian aid, etc.) use of the articles, etc. Subsequent to the loading, the mobile device 20 or another device (e.g., a fork lift, crane, conveyor, etc.) may move the loaded first support surface 30 onto a vehicle (e.g., a ship, train, truck, helicopter, airplane, submersible, spacecraft, etc.) for transport to another location (e.g., final destination), or into a building (e.g., warehouse, business, etc.) or other facility for storage or subsequent distribution.

(21) FIG. 2 is a system block diagram illustration of the mobile device 20. The mobile device 20 includes device electronics and/or mechanisms operable to (e.g., fully and/or semi-) autonomously perform one or more tasks such as, for example, loading article(s) onto support surface(s) as illustrated in FIG. 1. The device electronics and/or mechanisms may include a sensor system 44, a device interface system 46, memory 48, a mobile platform 50 (e.g., drive system), a manipulator system 52, and a controller 54. The present invention of course is not to be limited to the aforesaid electronics and/or mechanisms, and may include alternate electronics and/or mechanisms other than those specifically described herein as well as known or future equivalents thereof.

(22) The sensor system 44 is configured to survey the mobile device's surroundings and operating environment, and/or to receive location data. The sensor system 44 may include, for example, one or more location and/or proximity sensors that spatially locate (e.g., triangulate) the mobile device 20 relative to, for example, its surrounding environment, its geographic location, and/or one or more locators (e.g., RF tags, physical landmarks, etc.). Examples of location and/or proximity sensors include, but are not limited to, global positioning system (GPS) receivers, radar systems, sonar systems, infrared sensors, lasers, cameras, radio transceivers, etc. The sensor system 44 may additionally or alternatively include one or more cameras, one or more electro-acoustic transducers (e.g., microphones), etc.

(23) The device interface system 46 is configured to receive instructions (e.g., vectors, commands, etc.) in the form of control data from an operator and/or from a remote control system. The device interface system 46 may also be configured to communicate data to the operator and/or to the remote control system. The device interface system 46 may include a communication device and/or an operator interface. The communication device may include a cellular, satellite and/or radio transmitter, and/or a cellular, satellite and/or radio receiver. The operator interface may include one or more input and/or output (I/O) devices such as, for example, a display screen, a speaker, a touch screen, a keypad, a voice command system with an electro-acoustic transducer (e.g., microphone), etc.

(24) The memory 48 (e.g., a non-transitory computer readable medium) may be configured to store software (e.g., program instructions) for execution by the controller 54. The memory may include a volatile memory and/or a nonvolatile memory. Examples of a volatile memory may include a random access memory (RAM) such as a dynamic random access memory (DRAM), a static random access memory (SRAM), a synchronous dynamic random access memory (SDRAM), a video random access memory (VRAM), etc. Examples of a nonvolatile memory may include a read only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a computer hard drive, etc.

(25) The mobile platform 50 is configured to move the mobile device 20 to various locations within its operative environment. The mobile platform 50 may include one or more motorized and/or steerable propulsion devices such as, for example, motorized drive wheels, motorized track systems, etc. An embodiment of the mobile platform 50 with motorized drive wheels 56 is illustrated in FIG. 3. An embodiment of the mobile platform 50 with motorized (e.g., robotic and multi-linkage) track systems 58 is illustrated in FIG. 4. The present invention of course is not limited to the aforesaid mobile platform configurations and components.

(26) Referring again to FIG. 2, the manipulator system 52 includes one or more electronically, hydraulically, pneumatically and/or mechanically actuated manipulators 60, 62 and 64 configured to move one or more articles within the operative environment. Examples of a manipulator include, but are not limited to, a robotic manipulator arm (e.g., a multi-axis manipulator arm), a pallet jack, a lift platform, a conveyor system, a slide carriage, a crane, etc. In the specific embodiment illustrated in FIG. 3, the manipulator system 52 includes a plurality of robotic manipulator arms 60 and 62 and a pallet jack 64. Each of the robotic manipulator arms 60 and 62 includes an end effector 66 connected to one or more arm members 68 (e.g., linkages). Examples of an end effector include, but are not limited to, a gripping device, a suction device, an electromagnet, a winch, a clasp, etc. Alternative examples of a manipulator system are disclosed in U.S. Pat. Nos. 7,902,784; 7,719,222 and 7,348,747, each of which is hereby incorporated by reference in its entirety.

(27) Referring again to FIG. 2, the controller 54 may be implemented using hardware or a combination of hardware and software. The controller 54 may include one or more processing devices, analog and/or digital circuitry, etc. The controller 54 is in signal communication (e.g., hardwired or wirelessly connected) with the sensor system 44, the device interface system 46, the memory 48, the mobile platform 50 and the manipulator system 52.

(28) FIG. 5 is a flow diagram of a method for loading a plurality of the articles (e.g., the articles 22, 24, 26 and 28) on the first support surface 30 using the mobile device 20 illustrated in FIGS. 1 and 2. In step 500, the controller 54 receives control data (e.g., one or more vectors, commands, etc.) through the device interface system 46. The control data may include inventory data, location data, etc. The inventory data may, for example, identify the contents, types, states (e.g., amorphous or non-amorphous), masses and/or weights, dimensions, et cetera, of the articles to be arranged on the first support surface. The location data may, for example, identify the respective article pickup locations, and/or the respective support surface locations. Alternatively, the controller 54 may autonomously determine the article pickup locations and/or the support surface locations using the sensor system 44 where, for example, the articles and/or the support surfaces are configured with RF ID tags, locator beacons, etc. The controller 54 may alternatively and/or additionally identify the articles using image and shape recognition software. The control data may also include other types of data such as, for example, scheduling data that designates on which support surface(s) and by when and/or in which order the articles should be loaded.

(29) In step 502, the controller 54 autonomously models at least some of the articles (e.g., the articles 22, 24, 26 and 28) in a stable article arrangement on the first support surface 30. The term stable is used to describe an article arrangement having, for example, (i) a relatively low center of gravity, (ii) articles that are substantially supported by the support surface and/or other articles in the arrangement, (iii) articles that are (e.g., equally) balanced on the support surface and/or other articles in the arrangement, etc.

(30) FIG. 6 illustrates an embodiment of a stable article arrangement 70 modeled having a geometry that fits and is positioned within a perimeter 72 of the first support surface 30. Articles (e.g., base articles 74, free standing articles 76, etc.) contacting the first support surface 30 are substantially (e.g., completely) supported by the first support surface 30. Articles 78 and 80 stacked on one or more of the base articles 74 and/or intermediate articles 78 are substantially supported by the respective articles upon which they are stacked. A bottom surface of the intermediate stacked article 78, for example, is substantially (e.g., completely) supported by a top surface of the base article 74, and substantially parallel to the first support surface 30. In another example, each bottom corner of the stacked article 80 is supported by top surfaces of the base articles 74 and the intermediate stacked article 78. The stacked articles 78 and 80 may weigh less than the articles upon which they are stacked. The stacked articles 78 and 80 may also have smaller geometries (e.g., horizontal cross sectional areas, etc.) than the articles upon which they are stacked. In some embodiments, the base articles 74 may be staggered relative the stacked articles 80 to interlock the articles together with frictional forces. The present invention of course is not limited to any particular placement and/or arrangement of the articles.

(31) Referring again to FIGS. 1, 2 and 5, the stable article arrangement may be computationally modeled using a constrained optimization program or algorithm such as, for example, a Mix Integer Linear Program (MILP) constrained optimization program. The controller 54, for example, may input a plurality of given, fixed and/or variable parameters into a plurality of equality and/or inequality constraint equations, and subsequently solve the equations using the constrained optimization program. The parameters may be indicative of, for example, (i) a number of articles to be arranged on the support surface, (ii) dimensions of the articles and the support surface, (iii) weights and/or masses of the articles, (iv) dimensions between each article and one or more other articles and/or the support surface, (v) maximum dimensions for the article arrangement, etc. The constraint equations may be formulated to describe, for example, (i) spatial orientations of the articles relative to other articles and/or the support surface, (ii) relative positions of the articles relative to other articles and/or the support surface, (iii) the manner in which the articles are supported, (iv) the order in which the articles will be used at their destination, etc. The present invention of course is not limited to any particular type of optimization programs, parameters and/or constraint equation formulations.

(32) The stable article arrangement may also be modeled to efficiently load and tightly pack the articles 22, 24, 26 and 28 on the first support surface 30. The controller 54, for example, may iteratively change one or more of the parameter values within the constraint equations to model the articles in a plurality of different arrangements. The controller 54 may subsequently identify an optimum modeled article arrangement as, for example, the modeled article arrangement that (i) fits the greatest number of articles on the first support surface 30, (ii) has the greatest arrangement density, and/or (iii) has the greatest control volume density.

(33) The term arrangement density is used to describe a ratio of a collective volume of the articles in the modeled article arrangement to an overall volume of the modeled article arrangement. The collective volume may be determined by adding together volumes of the respective articles 22, 24, 26 and 28 in the modeled article arrangement. The overall volume may be determined by adding the collective volume to volumes of respective spaces (e.g., gaps) between the articles 22, 24, 26 and 28 in the modeled article arrangement. The controller 54 may utilize the arrangement density to identify the modeled article arrangement that packs the articles closest together.

(34) The term control volume density is used to describe a ratio of the collective volume to a control volume. The control volume may be given, or determined from a surface area of the support surface 30, and a control volume height (e.g., maximum vertical article arrangement height). The control volume height may be sized based on, for example, a height of a shipment container, a trailer, a cargo hold, etc. The control volume density may be utilized by the controller 54 to identify the modeled article arrangement that most efficiently packs the articles 22, 24, 26 and 28 within the control volume.

(35) In step 504, the controller 54 autonomously schedules the order in which the articles 22, 24, 26 and 28 in the optimum modeled article arrangement are to be gathered and moved to the first support surface 30 location. The controller 54, for example, may schedule the base articles to be gathered and moved before the stacked articles such that the stacked articles may be properly disposed on the base articles. In another example, the controller 54 may schedule the article proximate a back side of the first support surface to be gathered and moved before the articles proximate to a front side of the first support surface.

(36) In step 506, the mobile device 20 autonomously gathers one or more of the articles (e.g., the article 28) in the optimum modeled article arrangement. The controller 54, for example, may signal the mobile platform 50 to move the mobile device 20 to the article 28 pickup location. The controller 54 may subsequently signal the manipulator system 52 to pick up the article 28 with one or more of the robotic manipulator arms (e.g., the manipulator arm 60). The end effector 66, for example, may engage (e.g., grip) the article 28 utilizing one of a plurality of (e.g., predetermined) article engagement (e.g., gripping) techniques, and the arm member 68 may lift the article 28 off of the respective source pallet 36. In another example, the controller 54 may signal the manipulator system 52 to pick up one of the articles with the first robotic manipulator arm 60, and to pick up another one of the articles with the second robotic manipulator arm 62.

(37) The controller 54 may select the article engagement technique used to engage (e.g., grip, push, etc.) the article(s) based on, for example, the type and/or state of the article 28 being gathered, the orientation of the article 28 relative to the source pallet 36 and/or the mobile device 20, how the article is to be moved (e.g., lifted, pushed, cradled, etc.), etc. Each of the article engagement techniques may define, for example, a specific gripping force or range of gripping forces, a relative end effector spatial orientation, how far to open the (e.g., gripping) end effectors 66, etc. The controller 54, for example, may select a gripping technique that uses a relatively large gripping force to grasp a heavy article, and a relatively small gripping force to grasp a light or fragile article or an article having an amorphous state. FIGS. 7 and 8 illustrate a plurality of autonomous mobile robots utilizing various examples of the gripping techniques.

(38) Referring again to FIGS. 1, 2 and 5, in step 508, the mobile device 20 autonomously moves the gathered article(s) from the respective article pickup location(s) to the first support surface 30 location. The controller 54, for example, may signal the mobile platform 50 to move the mobile device 20 from the first article pickup location to the first support surface location.

(39) In step 510, the mobile device 20 autonomously arranges the gathered article(s) on the first support surface 30 according to the optimum modeled article arrangement. The controller 54, for example, may signal the manipulator system 52 to place the article 28 in a particular position and orientation on the first support surface 30 using, for example, the robotic manipulator arm 60 holding the article 28.

(40) In step 512, the mobile device 20 may repeat the steps 506, 508 and 510 to gather, move and arrange the remaining articles of the optimum modeled article arrangement.

(41) In step 514, the mobile device 20 may autonomously secure the articles 22, 24, 26 and 28 together and/or to the first support surface 30. The mobile device 20, for example, may utilize the manipulator system 52 to wrap the articles together in packaging material such as, for example, shrink wrap, transparent or non-transparent plastic wrap, etc. In another example, the mobile device 20 may utilize the manipulator system 52 to secure the article arrangement to the first support surface 30 with, for example, tie down straps.

(42) In some embodiments, the step 508 may be omitted from the method of FIG. 5 where, for example, the articles 22, 24, 26 and 28 may be respectively gathered and subsequently (e.g., immediately) arranged on the first support surface 30. Such an embodiment is illustrated in FIGS. 9A-9F where the pallet jack 64 is engaged with a pallet 82 that defines the first support surface 30. In other embodiments, the pallet 82 may be utilized to temporarily hold the gathered article(s) during movement of the article(s) between the article pickup location(s) and the first support surface location; i.e., where the step 508 is not omitted.

(43) In some embodiments, where the articles identified in the step 500 cannot fit within the control volume of a single support surface, the controller 54 may model a first grouping of the articles in a first stable article arrangement on the first support surface, a second grouping of the articles in a second stable article arrangement on a second support surface, etc. The controller 54 may also utilize the constrained optimization program to reduce (e.g., minimize) the number of support surfaces necessary to hold the identified articles. In such an embodiment, the mobile device 20 may perform the steps 506, 508 and 510 iteratively for each of the modeled article arrangements, or substantially concurrently in a manner that reduces (e.g., minimizes) loading time. The loading time may be minimized, for example, by gathering and arranging a similar type of the articles onto a plurality of the support surfaces before beginning the gathering and arranging of another type of the articles. Alternatively, the mobile device 20 may signal a second mobile device to load the second support surface while the mobile device 20 loads the first support surface, etc.

(44) In some embodiments, the constraint equations used in the step 502 may be weighted in order to arrange certain types of the articles at certain positions within the modeled article arrangement. Such weighting may be useful, for example, where certain types of the articles are scheduled to be unpacked at a final destination before other types of the articles, are scheduled to be removed mid-transit, etc.

(45) In alternate embodiments, a remote control system may be provided that autonomously controls one or more mobile devices to load one or more support surfaces. The control system, for example, may perform the steps 500, 502 and 504 and subsequently autonomously coordinate and signal a first of the mobile devices and a second of the mobile devices to gather and arrange respective articles on the first support surface. In another example, the control system may autonomously coordinate and signal the first of the mobile devices and the second of the mobile devices to gather and arrange respective articles on different support surfaces that are to be transported to and/or stored in, for example, the same location. In some embodiments, the control system may select which of the mobile devices loads which of the support surfaces based on, for example, the mobile device's proximity to the article pickup locations and/or support surface locations, the mobile device's load capacities or fuel/battery level, etc.

(46) During transportation, warehousing and/or storage of a loaded support surface, one or more articles in an article arrangement 84 on the support surface may be damaged, stolen, replaced with other articles, or otherwise tampered with, which may alter the geometry and appearance of the article arrangement as illustrated in FIGS. 10A and 10B. The geometry and appearance of the article arrangement 84 may change, for example, where (i) one of the perimeter articles is missing, (ii) one of the articles is replaced with an article having a different size or physical appearance, (iii) the packaging material wrapped around the article arrangement is removed and replaced with different packaging material or wrapped in a different manner, etc.

(47) FIG. 11 illustrates a system 86 for monitoring articles in an article arrangement on a loaded support surface. The system 86 may include the mobile device 20 and an article inspection system 88. The article inspection system 88 includes a processing device 90 that is in signal communication with a communication device 92 as well as a camera 94, a printer 96 and/or a display screen 98. The mobile device 20 may be located at a first location (e.g., an article distribution/loading facility, etc.), and the article inspection system 88 may be located at a second location (e.g., an article receiving facility, another article distribution/loading facility, a final destination, etc.).

(48) FIG. 12 is a flow diagram of a method for monitoring the articles in an article arrangement using the system 86 of FIG. 11. In step 1200, the mobile device 20 performs the method of FIG. 5 to arrange the articles on the support surface according to an autonomously modeled article arrangement.

(49) In step 1202, the controller 54 (see FIG. 2) generates image data from the modeled article arrangement, where the image data is indicative of an image of the arranged articles on the loaded support surface. The imaged data may be generated, for example, by processing the modeled article arrangement with given or determined dimensions and geometries of the articles in the modeled article arrangement. The controller 54 may also fit a surface to the modeled article arrangement to represent the packaging material wrapped around the articles in the step 514 (see, e.g., FIGS. 10A and 10B). It is contemplated that image data may include a datum that establishes an image coordinate system for the image.

(50) In step 1204, the mobile device 20 transmits the image data to the processing device 90 through the communication device 92. The image data may be transmitted before, after and/or during the transportation of the loaded support surface from the first location to the second location.

(51) In step 1206, the image data received by the processing device 90 is utilized to inspect the arranged articles on the loaded support surface at the second location. The processing device 90, for example, may signal the printer 96 to print the image of the arranged articles. An inspector, security guard, dock worker, government employee, etc. may subsequently visually compare the arranged articles on the loaded support surface to the printed image to determine whether any of the articles are damaged, tampered with, missing, etc. In another example, the processing device 90 may signal the display screen 98 to display the image of the arranged articles such that it may be visually compared to the arranged articles on the loaded support surface.

(52) In other embodiments, the processing device 90 may receive second image data from the camera 94, where the second image data is indicative of a second image of the arranged articles on the loaded support surface at the second location. The processing device 90 may subsequently compare one or more image characteristics between the first image data and the second image data to determine whether any of the articles are damaged, tampered with, missing, etc. The image characteristics may be compared utilizing, for example, image and/or shape recognition software. In some embodiments, the inspection system 88 may autonomously generate the second image data with the camera 94 and compare the first and second image data where, for example, the inspection system 88 is configured as the mobile device 20 described above.
