[0016] In one aspect, without limitation, the present disclosure is generally directed to reducing excessive labor and time in the installation of a moving area connected to a storage structure. This moving area can generally be configured to be usable by a mobile robot that retrieves totes of merchandise stored in a specific storage location within an adjacent storage structure that is part of an automated storage and retrieval system. This moving area can enable the robot to access different areas of the automated storage and retrieval system from the storage structure. The robot can use various features for navigation and position recognition, but these may need to be created at great cost and risk within a custom build. Typically, the construction of the moving area can be done on-site and can involve multiple layers of installation procedures that can cause multiple errors. The installation procedures can include the construction of a frame and a floor setting, followed by the construction of navigation features and posts for maneuvering the robot.

[0017] In one aspect, without limitation, the present disclosure utilizes the manufacturing of modular components in a factory setting using prefabricated panels (or tiles) that can be assembled efficiently and with low risk. Further, the present disclosure results in the manufacturing of guidelines on the panel surface for the movement of the robot. Additional features may be incorporated on the panel surface for the position recognition of the robot. This innovation enables a modular and scalable construction of the moving area, thereby reducing costs and eliminating assembly risks. It also reduces the amount of manufacturing work on-site.

[0018] Figures 1 and 2 show diagrams of an automated storage and retrieval system 100. In one form, this system 100 can be incorporated wholly or in part into an order fulfillment facility. The system 100 can include one or more storage structures 102 having a number of storage locations 104. Each storage structure 102 can include a y-z arrangement of horizontally aligned storage locations and vertically changing levels of a vertical tower. The mobile robot 108 can move between storage levels in the z-direction within a tower having changing levels. The storage structure 102 can form a pair of storage bays 110 that are arranged opposite each other and separated by a path 112. In one form, the path 112 can be in the form of a passageway, and the passageway 112 can have a width such that a mobile robot 108 moving within the passageway 112 can transfer a container to (or retrieve a container from) a storage bay 110 on either side of the passageway 112. Generally, the mobile robot 108 is assumed to be able to transport totes of merchandise from storage locations 104 to several designated areas for picking up the merchandise. In some forms, the mobile robot 108 can also carry a tote for containing merchandise that is returned to the storage structure 102.

[0019] Figures 1 and 2 show an example of a movement area 114, i.e., an In-Rack Transfer Plane (IRTP), which will be discussed in more detail below. The movement area 114 can be positioned at different vertical levels between storage structures 102. The movement area 114 enables the mobile robot 108 to access different passageways of the storage structure 102, access different storage structures, or access other areas of the system or facility.

[0020] As described above, the automated storage and retrieval system 100 may utilize several mobile robots 108 to transport totes or other product or order containers to and from storage locations 104. The term “tote” broadly refers to any type of container that can be used to hold goods. The mobile robots 108 may be self-guided and / or rail-guided to move horizontally and vertically within aisles 112 to transport totes or other product containers between the mobile robots 108 and storage locations 104. The mobile robots 108 may have access to storage shelves on either side of aisles 112 in the x-direction at a given level. As mentioned, the system 100 may also include a vertical tower with varying levels, in which the mobile robots 108 may move vertically in the z-direction between levels in storage locations 104.

[0021] Further details of storage structures, mobile robots, and various other embodiments of automated storage and retrieval systems that may be used are described, for example, in the following U.S. patents and patent applications: U.S. Patent No. 9,139,363, U.S. Patent No. 10,435,241, U.S. Patent No. 11,142,398, U.S. Patent No. 10,984,375, U.S. Patent No. 10,952,533, U.S. Patent No. 11,267,651, U.S. Patent Application No. 63 / 127,762, and U.S. Patent Application No. 17 / 957,266. Each of these patents and applications is incorporated herein by reference in whole.

[0022] Figure 3 shows a portion of the automated storage and retrieval system 100 with a portion of the storage structure removed for clarity. Figure 3 shows three stacked mobile areas 114 located at different vertical levels, i.e., between and connecting two storage structures 102A and 102B. As will be further described below, each mobile area 114 is generally in the form of a panel floor supported by a beam frame. The ends of each mobile area 114 are attached to the corresponding ends of each storage structure 102A and 102B to the support columns 116. In one embodiment, a mobile robot 108 is assumed to retrieve totes containing goods from storage locations 104 within each storage structure 102A and 102B. The movement area 114 allows the mobile robot 108, exiting the storage structure 102A through passage 112, to change direction and enter a different passage 112 within the same storage structure 102A, or to orient itself to enter a selected passage 112 within the second storage structure 102B, or to move to a different area within the automated storage and retrieval system 100 (such as a designated order pickup area).

[0023] Figure 4 shows another part of the automated storage and retrieval system 100 with a portion of the storage structure removed for clarity. Figure 4 shows two mobile areas 114 at different vertical levels adjacent to the storage structure 102. One end of each mobile area 114 is attached to a support column 116 at the corresponding end of the storage structure 102. The other end of each mobile area 114 is attached to another support column 116. The mobile areas 114 allow a mobile robot 108 exiting the passage 112 from the storage structure 102 to change direction and enter a different passage 112 within the same storage structure 102A, or to move to a different area within the automated storage and retrieval system 100 (such as a designated order pickup area).

[0024] Accordingly, in some embodiments, the automated storage and retrieval system 100 includes one or more storage structures 102 and a plurality of mobile robots 108. In one embodiment, the system 100 may include a first storage structure 102A that includes a plurality of storage locations 104 configured to store totes containing goods. The first storage structure 102A may include a plurality of passages 112, through which each storage location 104 is accessible. The system 100 may also include a plurality of mobile robots 108 configured to travel through the plurality of passages 112 of the first storage structure 102A. Each mobile robot 108 may be configured to access the storage locations 104 and place or retrieve totes from the storage locations 104. The system 100 may also include a second storage structure 102B that includes a plurality of storage locations 104 configured to store totes containing goods, the second storage structure 102B includes a plurality of passages 112, through which each storage location 104 is accessible.

[0025] Referring to Figure 5, a partially assembled mobile area 114 is shown. The drawing shows only the support ends of one or more storage structures 102. The mobile area 114 includes a frame section 118 and a floor 120. The frame section 118 includes several beams 122 that are attached to one or more storage structures 102. In the example of Figure 3, two ends of the beams are attached to the corresponding ends of storage structures 102A and 102B. In the example of Figure 4, one end of the beam is attached to the corresponding end of storage structure 102, while the other end of the beam is attached to a support column 116. Thus, the beams 122 of the frame section 118 support the floor 120.

[0026] Figures 6 and 7 show the assembled mobile area 114. In one embodiment, the mobile area 114 may consist of two types of panels: mobile panels 124 and connecting panels 126. In the drawings, in this particular example, there are four mobile panels 124. Each mobile panel 124 may include guidelines 128 extending along two centerlines of each mobile panel 124, thereby dividing each mobile panel 124 into four sections. These guidelines 128 enable guided movement by the mobile robot 108 along these centerlines, as will be further described below. The connecting panel 126 extends in a central strip between two sets of mobile panels 124. In this embodiment, panels 124 and 126 are fastened to each other by cleats 130, as also shown in Figure 8. These cleats 130 are optional, and in another embodiment, alternative fasteners may be used. Furthermore, as shown in Figure 7, a transition plate 132 may be provided to connect the passage 112 within the storage structure 102 to the guideline 128 of the panel 124 and align them. This transition plate 132 will be described in more detail below.

[0027] Therefore, in some forms, the system 100 may include a mobile area 114 adjacent to the first storage structure 102A, providing a mobile robot 108 with access to enter and exit the passage 112 of the storage structure 102. The mobile area 114 may include a frame portion 118 formed of a plurality of beams 122 configured for attachment to the first storage structure 102A. Furthermore, the system 100 may include a floor 120 supported by the frame portion 118, the floor 120 being formed of a plurality of panels collectively defining the floor 120. The floor 120 may include at least one panel 124 having one or more guidelines 128 at predetermined locations on the panel 124 to facilitate the movement of the mobile robot 108 over it.

[0028] Referring to Figure 9, a top view of panel 200 is shown. In one embodiment, panel 200 having the features described below is envisioned to be used in general in the mobile area 114 and the automated storage and retrieval system 100. These may be prefabricated in whole or in part and may be used modularly on the floor of the mobile area 114. In another embodiment, panel 200 is also envisioned to be used in other situations where it is desirable to provide a surface for the movement and navigation of a mobile robot.

[0029] Panel 200 may be roughly rectangular in shape and may include two guidelines 202 formed roughly along the horizontal and vertical centerlines of panel 200. In this configuration, the robot may move along one of the centerlines and then, at or approaching the intersection of the two centerlines, may move in a straight line or change direction. Although the guidelines 202 are shown to be formed along the horizontal and vertical centerlines of panel 200, it is also envisioned that other forms of guidelines may be used. For example, the guidelines 202 may be positioned at some predetermined non-perpendicular angle to the edges of the panel. Furthermore, it is also envisioned that the guidelines may take the form of a spaced pattern at predetermined locations on panel 200 that the robot can detect and use for navigation. Other robot guides are also available.

[0030] In one embodiment, the guideline 202 may be a magnetic guideline, and at least one groove is configured to receive a press-fit metal material to form one or more magnetic guidelines 202. In this embodiment, the magnetic guideline 202 may be created by pressing a magnetic material into a groove designed to capture a line in a press-fit without the need for adhesive. It is also envisioned that these magnetic guidelines 202 may be prefabricated elsewhere by the panel manufacturer before being shipped and installed to form the floor 120 of the moving area 114. In one embodiment, the panel may be partially formed of a resin material.

[0031] Referring to Figure 10, a schematic side view of panel 200 is shown in which a mobile robot 108 moves over panel 200. As can be seen, panel 200 includes magnetic guidelines 202 formed on the upper surface of panel 200. In one embodiment, it is assumed that the mobile robot 108 may include a magnetic sensor 109 that detects one or more magnetic guidelines 202 to facilitate the movement of the mobile robot 108 over panel 200. This magnetic sensor 109 may be a Hall effect sensor and may be located on the bottom of the mobile robot 108. In some situations, it may be desirable to use magnetic guidelines 202 rather than painted guidelines. Painted guidelines may tend to wear off over time and may not be detected by the mobile robot 108's optical sensors under certain conditions, such as when the mobile robot 108 moves in and out of a temperature-controlled environment. In these situations, the optical sensors used to follow painted lines may become cloudy and stop working.

[0032] Figure 9 also shows alignment features for aligning the panel 200 to a specific orientation, such as during installation in the moving area 114. In one embodiment, the panel 200 may include alignment features for aligning magnetic guidelines 202 in a predetermined manner with respect to a corresponding passage 112, the corresponding passage 112 being configured to allow a mobile robot 108 to exit from the passage 112 to the panel 200. These alignment features may include at least two mounting holes 208 at predetermined locations on the panel 200, each of which is configured to receive fasteners. As can be seen, in one embodiment, these mounting holes 208 may be located near the edges of the panel 200 corresponding to the long sides of a rectangle. These mounting holes 208 receive fasteners that secure the panel 200 to the beam 122 below.

[0033] In one embodiment, these mounting holes 208 align the magnetic guideline 202 with the corresponding passage. In other words, in one embodiment, the mounting holes 208 make it possible to precisely position the magnetic guideline 202 of the panel 200 at the center of the passage centerline of the storage structure 102. Furthermore, this alignment feature can be used to make installation easier and reduce installation errors by allowing the panel 200 to be installed in only a specific orientation. For example, as shown in Figure 9, the mounting holes 208 may be arranged so that the panel 200 can be installed in only one of two orientations, i.e., with its long side parallel to the end of the storage structure 102. In other words, there may be two sets of mounting holes 208, each set located adjacent to the edge of the long side, thereby allowing the panel 200 to be installed in one of two orientations. This arrangement of mounting holes is asymmetrical in that it is not possible to install the panel 200 in the other two orientations, thereby reducing installation errors. Alternatively, as another example, the mounting holes 208 may be arranged so that the panel 200 can be installed in exactly one orientation. In one embodiment, it is also envisioned that these mounting holes 208 may be formed elsewhere by the panel manufacturer before being shipped and installed to form the floor 120 of the moving area 114.

[0034] Figure 9 also shows two sets of fastening holes 210 arranged parallel to each other. In some embodiments, these two sets of fastening holes 210 are also envisioned to be used as a substitute for the cleats 130 described above. This pattern of fastening holes 210 may allow the panel 200 to be fastened to the beam 122 using standard self-tapping screws. Again, in one embodiment, these fastening holes 210 are also envisioned to be formed by the panel manufacturer before installation.

[0035] Panel 200 may include features to assist navigation by the mobile robot 108. For example, panel 200 may include at least one reference marker 212 applied to the upper surface of panel 200. As shown in Figure 9, in one embodiment, two reference markers 212 may be formed near the center of panel 200. In this embodiment, the two reference markers 212 are positioned in an oblique orientation with respect to the horizontal magnetic guideline 202 and the vertical magnetic guideline 202. Furthermore, in this embodiment, they are in opposing quadrants on the opposite side of panel 200, as defined by the horizontal magnetic guideline 202 and the vertical magnetic guideline 202, and are generally symmetrical with respect to the center. This symmetrical arrangement makes it possible to install panel 200 in one of two orientations (one orientation being 180 degrees to the other).

[0036] In one embodiment, it is assumed that grooves can be cut into the panel 200 during its prefabrication and before its installation. After the panel is installed, reference markers in the form of reference magnets can be placed in these grooves. In other words, the reference markers 212 can be applied or formed after the panel 200 is installed.

[0037] These reference markers 212 can be used as reference points to enable the mobile robot 108 to locate its position and assist in navigation. Generally, these reference points are assumed to be detectable by the mobile robot 108's imaging sensors. In other words, the reference markers 212 are configured to facilitate position determination and navigation by the mobile robot moving on the floor 120 of the mobile area 114. While an example of reference marker type and arrangement is shown, it should be understood that other types and arrangements may be used.

[0038] Another feature that can be used as a navigation aid is an RFID tag 214. The RFID tag 214 can be used in addition to, or as a substitute for, the reference marker 212. For example, as shown in Figure 9, the top surface of the panel 200 includes markings 213 for drilling holes for the installation of (one or more) RFID tags 214. These markings may be arranged symmetrically with respect to the center of the panel 200 so as to allow the panel 200 to be installed in one of two orientations. Furthermore, in one embodiment, these markings are applied during the prefabrication of the panel 200.

[0039] Furthermore, as shown in Figure 10, it is assumed that the RFID tags 214 can generally be applied to the bottom surface, or underside, of the panel 200. In one embodiment, holes are drilled through the panel 200 to allow the RFID tags 214 to be applied to the bottom surface after the panel 200 has been installed. The panel 200 may include at least one RFID tag 214 applied to the bottom surface of the panel 200. The RFID tags 214 are configured to facilitate position determination and navigation by a mobile robot moving on the floor 120.

[0040] As described above, the automated storage and retrieval system 100 may include a transition plate 132. Figure 11 is a partial top view of a panel 200 connected to the transition plate 132, and Figure 12 is a partial perspective view of the panel 200 connected to the transition plate 132. In one embodiment, the transition plate 132 is located midway between the panel 200 and the corresponding passage 112 of the storage structure 102.
