The docking actuator 130 maintains an upward movement 510 of the docking head 110 until the docking sensor 460 detects contact between the docking head 110 and the docking plane 350. This third step aligns the vertical surfaces of the docking cone 410 and control spine 420 with the vertical inner surface of the docking plate 350. As a result of this alignment, the docking cone 410 and control spine 420 can transmit lateral forces to the inner surface of the docking plate 350, which causes horizontal and / rotational movement within the inventory holder 30. ).
FIG. 5G shows the movable drive device 20 and the inventory holder 30 during the fourth stage of the docking operation. In the illustrated embodiment, this fourth step is initiated by the docking sensor 460 detecting contact between the docking head 110 and the docking plate 350. After the docking sensor 460 detects contact between the docking head 110 and the docking plate 350, the docking actuator 130 can continue to raise the docking head 110. As the weight of the inventory holder 30 shifts from the leg 328 to the movable drive device 20, the inventory holder 30 begins to exert a downward force 540 on the movable drive device 20. The downward force 540 increases the traction between the motorized wheel 124 and the floor of the work space, improving the mobility of the movable drive unit 20. The movable drive device 20 then determines when sufficient force has been transferred to the motorized wheel 124 and terminates the docking operation. In this regard, some or all of the weight of the inventory holder 30 can be supported by the docking plate 350.

In step 610, the movable drive device 20 configures the drive module 120 so that the movable drive device 20 can roll.
In step 615, the movable drive device 20 activates the first stage of the docking operation. As mentioned above, the first stage of "activation" can represent that the movable drive device 20 continues to raise the docking head 110 after the apex of the docking cone 410 has entered the docking cavity 440. In step 620, the docking cavity 440 causes a translation 520 within the movable drive 20 to align the docking head 110 with the docking plate 350. In step 625, the movable drive device 20 detects the translation 520 at the docking head 110 and / or the movable drive device 20. In response, the movable drive device 20 propels the movable drive device 20 in the direction of the translation 520 in step 630 to actively assist in aligning the docking head 110 with the docking plate 350. As mentioned above, in certain embodiments, the mobile drive 20 is instead passive by configuring the drive module 120 to allow the mobile drive 20 to roll in the direction of translation 520. Only support can be provided.
In step 635, the movable drive device 20 activates a second stage of the docking operation. As with the first stage, "activating" the second stage may indicate that the movable drive 20 continues to raise the docking head 110 after the apex of the control spine 420 has entered the control cleft 450. .. In step 640, the control cleft 450 causes a rotational movement 530 within the docking head 110 to align the docking head 110 with the orientation of the docking plate 350. The movable drive device 20 detects the rotational movement 530 in step 645. In step 650, the movable drive device 20 is actively rotated in the direction of the rotational movement 530 to assist in the alignment of the docking head 110 and the docking plate 350. Again, in certain embodiments, the drive-moving device 20 is a drive module 120 or docking head to allow the docking head 110 and / or the movable drive device 20 to rotate in the direction of rotational movement 530. Only passive support can be provided by configuring 110.
In step 655, the docking head activates a third stage. The "activation" of the third stage may represent continuing to raise the docking head 110 after the docking head 110 and the docking plate 350 have been aligned. In step 660, the movable drive device detects contact between the docking head 110 and the docking plate 350.
The movable drive device 20 activates the fourth step in step 665 in response to the detection of this contact. The fourth stage of "activation" can represent keeping the docking head 110 raised after bringing the docking head 110 and the docking plate into contact with each other. In step 670, the movable drive 20 determines that there is sufficient downward force on the movable drive 20 to provide sufficient traction between the motorized wheel 124 and the floor. .. The movable drive device 20 starts moving the movable drive device 20 and the inventory holder in step 675 to complete the docking operation.
As mentioned above, the mobile drive device 20 can be further configured to detect a failed attempt to complete any or all of the steps shown in FIG. Further, the mobile drive device 20 can be configured to repeat any one or more failed steps until the failed steps are successfully completed or a predetermined maximum number of trials fail. For example, in a particular embodiment, if a particular step of the mobile drive 20 is not successfully completed, the mobile drive 20 repeats the appropriate steps up to three times and then again in the steps above. You can try to complete it. After three failed attempts, the mobile drive 20 can abort the docking attempt and contact the management device of inventory system 10 to notify the management device of the failed docking attempt.
The movable drive device 20 can also be configured to rotate and try docking again in response to detection of a failed docking attempt. For example, certain embodiments of the mobile drive device 20 may only be able to roll forward or backward along the axis defined by the motorized wheel 124. Thus, the docking plate 350 may be able to cause translation 520 only along its axis.
As a result, certain embodiments of the mobile drive device 20 may complete the first stage of docking by raising the docking head 110 until the apex of the control spine 420 enters the control cleft 450. This results in the alignment of the docking head 110 and the docking plate 350 along the first axis. The movable drive device 20 can lower the docking head 110 and rotate the motorized wheel 124 so as to define a second axis perpendicular to the first axis. The movable drive device 20 can then repeat the first stage of the docking operation. This provides an alignment of the docking head 110 and docking plate 350 along the second axis. The mobile drive device 20 can then complete the rest of the docking operation as described above. Part of this procedure can also be used while the inventory holder 30 is being unloaded at the storage location to ensure that the inventory holder 30 is aligned with the grid of the inventory system 10.
7A-7H show steps in the operation of a particular embodiment of the movable drive device 20 in moving the inventory holder 30. The movable drive device 20 can be configured to move the inventory holder 30 in any suitable manner. As a result, certain embodiments of the mobile drive device 20 can utilize moving techniques that, when used in the inventory system 10, provide a particular benefit. For example, FIGS. 7A-7H show specific embodiments of the mobile drive 20 that provide space-saving benefits when operating in inventory system 10. In particular, FIGS. 7A-7H show the movable drive 20 as the movable drive 20 moves the inventory holder 30 from the first position to the second position along a path that includes a 90 degree rotation. Shows the operation of. As illustrated, the inventory system 10 includes a plurality of grid positions 710a-710c that represent separate physical locations within the workspace associated with the inventory system 10. This procedure can also be used while the inventory holder 30 is being unloaded at the storage location to ensure that the inventory holder 30 fits into the grid.
FIG. 7A shows the starting location of the movable drive device 20 and the inventory holder 30. Initially, the movable drive 20 is in grid position 710b and the inventory holder 30 is in grid position 710a. As shown in FIG. 7B, the movable drive device 20 moves to grid position 710a and places itself under the inventory holder 30. At this point, the movable drive device 20 is undocked with the inventory holder 30, as shown by the absence of the docking head 110 in FIG. 7B. As shown in FIG. 7C, the movable drive device 20 then docks with the inventory holder 30, as shown by the schematic of the docking head 110. The movable drive device 20 then propels the movable drive device 20 and the inventory holder 30 to grid position 710b as shown in FIG. 7D. At grid position 710b, the movable drive device 20 undocks with the inventory holder 30 as shown in FIG. 7E. The movable drive device 20 then rotates as shown in FIG. 7F.
