[0116] In some embodiments, the storage system further comprises an elevator 400, which comprises a ground operating platform 402 and a lifting conveying device (not shown in the figure), and the ground operating platform 402 can be used by the ground operator 502 to take or place the storage object, which can be, for example, the sorted goods placed on the ground operating platform 402 by the operator 502 after sorting the to-be-sorted goods transported to the ground operating platform 402. The lifting conveying device is used to transfer the storage object between the ground operating platform 402 and the retrieval robot 300 at the transfer opening 256.

[0117] As Figure 2 shown, in one implementation, the ground operating platform 402 is a semi-automatic operating platform, which comprises, for example, a conveying belt that can convey the storage object placed on the conveying belt by the operator 502 to the lifting conveying device, and the lifting conveying device lifts the storage object to the top of the storage unit 200 and then delivers it to the retrieval robot 300 at the transfer opening 256 at the edge of the platform track system 240. It can be understood that the storage system can be configured with multiple elevators 400 and multiple retrieval robots 300 to improve efficiency.

[0118] In other embodiments, the storage system further comprises a ladder for the operator to climb to the transfer opening 256 at the edge of the platform track system 240 to manually deliver the storage object to the retrieval robot 300. The delivered storage object can be, for example, the sorted goods sorted by the operator after the to-be-sorted goods are transported to the top of the storage unit.

[0119] In some embodiments, the warehousing system is equipped with an automated conveyor line that is height-matched to the platform track system 240. This automated conveyor line can be used to automatically deliver storage objects to the pick-up robot 300 at the sub-packing port 256, or to transport storage objects to an operator on a ladder, allowing the operator to manually deliver the storage objects to the pick-up robot 300 at the sub-packing port 256. For example, the automated conveyor line can transport goods to be sorted to the operator, who then delivers the sorted goods to the pick-up robot 300.

[0120] Figure 5 This diagram illustrates a block diagram of a pickup and delivery robot 300 according to an embodiment of this application. (See also...) Figure 5 As shown, the pickup and transport robot 300 includes:

[0121] The movable base 310 is used to drive the pick-up and drop robot 300 to move on the support surface, for example, to drive the pick-up and drop robot 300 to move along the platform track system 240;

[0122] The transfer device 330 includes a transfer member 337 and a first drive device 333 for driving the transfer member 337;

[0123] The lifting device 350 includes a lifting mechanism 351 and a second drive device 353 for driving the lifting mechanism 351. The lifting mechanism 351 is connected to the transfer device 330. The second drive device 353 is installed on the movable base 310 and is used to drive the lifting mechanism 351 to lower the transfer device 330 relative to the movable base 310 to a position corresponding to the target storage layer, so that the transfer member 337, driven by the first drive device 333, transfers the stored object between the transfer member 337 and the target storage layer.

[0124] In some embodiments, the transport robot also includes a control unit 360 for controlling the operation of the first drive unit 333 and the second drive unit 353 and controlling the movement of the movable base 310.

[0125] See Figure 6 In some embodiments, the movable base 310 includes a main body 312, a first drive wheel set 314 that can move in the same direction along a first direction, and a second drive wheel set 316 that can move in the same direction along a second direction. At least one of the first drive wheel set 314 and the second drive wheel set 316 is vertically mounted on the main body 312 so that the movable base 310 can move in the first direction or the second direction by alternately contacting the moving support surface.

[0126] In one specific implementation, the main body 312 of the movable base 310 is an annular body, extending through both ends along the lifting direction of the transfer device 330. The annular body has an inner annular wall, an outer annular wall, a top wall, and a bottom wall, which together define the internal receiving space 318 (e.g., Figure 11The internal accommodation space 318 can be used to accommodate a communication module, a power module, etc. of the picking robot 300, for example. The main body 312 is shown as a square ring body. It can be understood that the present application is not limited thereto, and the main body can also be a rectangular ring body, an oval ring body, etc. By setting the main body of the movable base as a ring body, the storage object can be loaded or unloaded from above the picking robot 300 when the transfer device 330 is in the retracted state.

[0127] The first driving wheel set 314 and the second driving wheel set 316 are arranged at the bottom of the main body 312. The driving wheels of the first driving wheel set 314 are arranged at the bottom of the main body 312 in the same direction along the first movement direction of the movable base 310 and are driven by one or more driving motors arranged in the internal accommodation space 318. The driving wheels of the second driving wheel set 316 are arranged at the bottom of the main body 312 in the same direction along the second movement direction of the movable base 310 and are driven by another one or more driving motors arranged in the internal accommodation space 318. The first movement direction and the second movement direction can be perpendicular to each other, but the present application is not limited thereto. The first driving wheel set 314 is shown as including four driving wheels, and two driving wheels are arranged on each of a pair of parallel edges of the square main body 312. The second driving wheel set 316 is shown as including four driving wheels, and two driving wheels are arranged on each of another pair of parallel edges of the square main body 312. It can be understood that in other embodiments, the driving wheels on each edge of the square main body 312 can be configured as one or more than two, for example.

[0128] In some embodiments, the driving wheels of the first driving wheel set 314 and the second driving wheel set 316 are installed on the main body 312 in a liftable manner to contact or leave the movement support surface. The lifting direction of the driving wheels is the same as the lifting direction of the transfer device 330. Figure 7 The state in which the driving wheels of the first driving wheel set 314 contact the movement support surface and the driving wheels of the second driving wheel set 316 leave the movement support surface is shown. At this time, the first driving wheel set 314 can move the movable base 310 in the first movement direction in a forward or reverse direction, Figure 8 The state in which the driving wheels of the second driving wheel set 316 contact the movement support surface and the driving wheels of the first driving wheel set 314 leave the movement support surface is shown. At this time, the second driving wheel set 316 can move the movable base 310 in the second movement direction in a forward or reverse direction. It can be understood that the driving motors and the lifting mechanism of the first and second driving wheel sets 316 can be arranged in the internal accommodation space 318 of the main body 312.

[0129] In this way, by controlling the first and second driving wheel sets 314, 316 to alternately contact the movement support surface, the movable base 310 can be moved in different directions. When the retrieval robot 300 is working under the guidance of the platform track system 240 on the top of the storage unit 200, by controlling the first and second driving wheel sets 314, 316 to alternately contact the tracks of the first track set 242 and the tracks of the second track set 244, the retrieval robot 300 can be moved in the first direction X or in the second direction Y.

[0130] In some embodiments, one of the first and second driving wheel sets 314, 316 is mounted on the main body 312 in a manner that can be lifted, for example, each driving wheel of the first driving wheel set 314 is mounted on the main body 312 in a manner that can be lifted, when each driving wheel of the first driving wheel set 314 is lowered to a position below each driving wheel of the second driving wheel set 316, each driving wheel of the first driving wheel set 314 contacts the movement support surface, and each driving wheel of the second driving wheel set 316 is away from the movement support surface, at this time, the first driving wheel set 314 can move the movable base 310 in the first movement direction in a forward or reverse direction; when each driving wheel of the first driving wheel set 314 is raised to a position above each driving wheel of the second driving wheel set 316, each driving wheel of the first driving wheel set 314 is away from the movement support surface, and each driving wheel of the second driving wheel set 316 contacts the movement support surface, at this time, the second driving wheel set 316 can move the movable base 310 in the second movement direction in a forward or reverse direction. It can be understood that, as an alternative, each driving wheel of the second driving wheel set 316 can also be mounted on the main body 312 in a manner that can be lifted, by controlling the lifting of the second driving wheel set 316, the first and second driving wheel sets 314, 316 are controlled to alternately contact the movement support surface.

[0131] In some embodiments, the first and second driving wheel sets 314, 316 are switched from the tracks in the first track set 242 to the tracks in the second track set 244 by differential rotation.

[0132] In some embodiments, the transfer device 330 includes a base body, a transfer member, a first driving device, and a rolling support member driven by the first driving device, the rolling support member is supported by the base body, and the transfer member is in belt transmission connection with the rolling support member.

[0133] Referring to Figures 9 to 12In one implementation, the transfer device 330 is a belt 338 transfer device 330, which includes a drum support 332, a driving drum 334 and a driven drum 336 rotatably supported on the drum support 332, and a belt 338 installed on the driving drum 334 and the driven drum 336. The drum support 332 as the base of the transfer device 330 includes a pair of substantially parallel support rods. The driving drum 334 and the driven drum 336 are supported between the pair of support rods, and the pair of support rods, the driving drum 334 and the driven drum 336 make the transfer device 330 have a shape substantially consistent with the main body 312. The first driving device 333, for example, includes a drum motor, and the stator of the drum motor is arranged inside the driving drum 334, and the driving drum 334 serves as the rotor of the drum motor. The driving drum 334 rotates after the drum motor is powered, and the belt 338 moves under the rolling support of the driving drum 334 and the driven drum 336, so that the storage object can be unloaded from the belt 338 to the target storage layer, or loaded onto the belt 338. It can be understood that in other implementations, the first driving device 333 can also be other types of motors, for example, can be arranged outside the driving drum 334, and a transmission mechanism such as a speed reduction gear train can be arranged between the first driving device 333 and the driving drum 334.

[0134] In some embodiments, the top ends of the pair of support rods 332 are provided with a pair of baffles 339 extending along the moving direction of the belt, which are used to limit the storage object to avoid the storage object from falling off the belt, while not affecting the loading and unloading of the storage object.

[0135] In some embodiments, the lifting device 350 is a rope lifting device, which includes a lifting rope 352 and a second driving device 353. The second driving device 353 can include a driving motor, for example, a rotary motor, installed on the main body 312 of the movable base 310 and arranged in the internal receiving space 318 of the main body 312. The transfer device 330 is suspended at one end of the lifting rope 352, and the other end of the lifting rope 352 is directly or indirectly connected to the output end of the second driving device 353. When the second driving device 353 outputs rotation in a first direction, the lifting rope 352 is wound, and the transfer device 330 is lifted; when the second driving device 353 outputs rotation in a second direction, the lifting rope 352 is unwound, and the transfer device 330 is lowered. By controlling the output rotation amount of the second driving device 353, the winding or unwinding degree of the lifting rope 352 can be controlled, so that the lifting or lowering distance of the transfer device 330 can be controlled. It can be understood that the lifting rope 352 can be a cable, a chain, or a belt, etc.

[0136] As Figure 9 and 10As shown, in one specific implementation, the rope lifting device 350 includes four lifting ropes 352 arranged at the four top corners of the main body 312, and the pair of support rods 332 of the transfer device 330 are respectively hoisted at one end of the four lifting ropes 352, and the other end of the lifting ropes 352 is directly or indirectly connected to the output end of the corresponding second driving device 353; by synchronously winding or unwinding the four lifting ropes 352, the transfer device 330 can be stably lifted or lowered.

[0137] Further, referring to Figure 11 As shown, the vertical dimension of the transfer device 330 is smaller than the vertical dimension of the main body 312, and the overall transverse dimension of the transfer device 330 is smaller than the transverse dimension of the inner hole 313 formed by the inner ring wall 312a of the main body 312, so that the transfer device 330 does not interfere with the main body 312 during lifting, and when the lifting device 350 is in a fully retracted state (in the specific example described above, i.e., the lifting ropes 352 are in a fully wound state), the transfer device 330 is in a retracted state and is accommodated in the inner hole of the main body 312, and the picking and transporting robot 300 is in a flat state. In this way, the picking and transporting robot 300 is more compact in structure and more stable when moving on the platform track system 240.

[0138] In some embodiments, the transfer device 330 is provided with a guide 340 for sliding contact with an external guide rail to guide the lifting of the lifting device 350 and stabilize the transfer device 330 during lifting.

[0139] In the specific implementation as shown, the base body of the transfer device 330 is provided with a guide block 340, and the guide block 340 slides along the guide rail 212 provided on the support 210 of the storage unit 200 during lifting of the transfer device 330, limiting the lifting trajectory of the transfer device 330. It can be understood that the guide block 340 can be provided at part of the top corners or all four top corners of the transfer device 330.

[0140] In some embodiments, the main body 312 of the movable base 310 is provided with a battery 320 (as shown in Figure 5 As shown, for example, in the inner accommodation space 318, which can be used to power the control unit 360, the driving motors of the first driving wheel set 314 and the second driving wheel set 316, the lifting mechanism, and the second driving device 353. The transfer device 330 is provided with an energy storage device 342 (as shown in Figure 5 The energy storage device 342 can be a battery or a capacitor, etc., which can be arranged inside the driving drum 334 or inside the base body. It can be understood that in other embodiments, the picking and transporting robot can also not be provided with an energy storage device, and the first driving device is powered by the battery.

[0141] In some embodiments, the battery 320 of the movable base 310 charges the energy storage device 342 of the transfer device 330. Further, the transport robot 300 is configured such that the energy storage device 342 is electrically disconnected from the battery 320 when the transfer device 330 descends, and electrically connected to the battery 320 when the transfer device 330 is in the retracted state. Thus, when the transfer device 330 is in the retracted state, the battery 320 charges the energy storage device 342; after the transfer device 330 descends to the target position, the energy storage device 342 supplies power to the first drive device 333, causing the transfer member 337 to unload the stored object from the transfer device 330 or load the stored object onto the transfer device 330 under the drive of the first drive device 333.

[0142] like Figures 9 to 11 As shown, in one specific implementation, the transfer device 330 is provided with a first electrical connection terminal 344 connected to the energy storage device 342, and the movable base is provided with a second electrical connection terminal 346 that mates with the first electrical connection terminal 344. The second electrical connection terminal 346 is connected to the battery 320. When the transfer device 330 is in the retracted state, the first electrical connection terminal 344 and the second electrical connection terminal 346 are in contact with each other, making the energy storage device 342 and the battery 320 electrically connected. During the descent movement of the transfer device 330, the first electrical connection terminal 344 and the second electrical connection terminal 346 are separated from each other, making the energy storage device 342 and the battery 320 electrically disconnected. In the figure, the first electrical connection terminal 344 is an electrical connection contact head, and the second electrical connection terminal 346 is an electrical connection contact piece. Understandably, as an alternative, the first electrical connection terminal 344 can be an electrical contact piece, and the second electrical connection terminal 346 can be an electrical contact head; alternatively, the first electrical connection terminal 344 and the second electrical connection terminal 346 can also form other forms of electrical connection structures, such as plug-in type. The energy storage device 342 can be a supercapacitor, configured to provide the power required for one transfer by the transfer device 330 after charging.

[0143] In some embodiments, the vertical top end of the main body 312 of the movable base 310 is provided with an inwardly extending step 312b. The inner wall of the step 312b can be used to limit the storage object and prevent the storage object from falling out of the transport robot 300; the bottom wall of the step 312b can be used to limit the movement of the transfer device 330 in the upward direction.

[0144] like Figures 9 to 11 In the specific implementation shown, the second electrical connection end 346 is located on the bottom wall of the step 312b, and the first electrical connection end 344 is located on the top surface of the base of the transfer device 330 facing the bottom wall of the step 312b. When the transfer device 330 is in the retracted state, the first electrical connection end 344 and the second electrical connection end 346 are in contact and connected in the lifting direction of the transfer device 330.

[0145] In some embodiments, the transfer device is a tilting transfer device, including a base, a tilting disk, and a first drive device for driving the tilting disk. The first drive device is mounted on the base. After the lifting device lowers the transfer device to a position corresponding to the target storage layer, the first drive device drives the tilting disk to tilt, causing the stored object inside the tilting disk to fall into the target storage layer under its own gravity. It is understood that a transmission mechanism, such as a reduction gear, may be provided between the first drive device and the tilting disk.

[0146] In some embodiments, the transfer device is a fork transfer device, including a base, forks, and a first drive device for driving the forks. The first drive device is mounted on the base. After the lifting device lowers the transfer device to a position corresponding to the target storage layer, the first drive device drives the forks to translate, causing the forks to push the stored object laterally to the target storage layer. Alternatively, the first drive device drives the forks to translate to the target storage layer and then move in the opposite direction, causing the forks to pull the stored object from the target storage layer onto the transfer device.

[0147] In some embodiments, the transfer device is a roller transfer device.

[0148] Alternatively, in some embodiments, the lifting mechanism 351 includes a scissor mechanism. One end of the scissor mechanism is mounted to a movable base, and the other end is mounted to the transfer device. The scissor mechanism extends and retracts under the drive of a second drive device, thereby lowering or raising the transfer device. The second drive device may be a drive motor, but is not limited to this.

[0149] Alternatively, in some embodiments, the lifting mechanism 351 includes a multi-stage telescopic mechanism. In one specific implementation, the multi-stage telescopic mechanism includes at least two telescopic arms that are slidably connected in sequence, and the at least two telescopic arms perform nested telescopic movements relative to the movable base under the drive of a second drive device. Alternatively, in some embodiments, the first drive device is configured to drive the transfer member to move forward or backward, such that when the transfer member moves forward, it unloads the stored object from the transfer device to one side, and when it moves backward, it unloads the stored object from the transfer device to the other side; or, it loads the stored object from one side into the transfer device when the transfer member moves forward, and loads the stored object from the other side into the transfer device when it moves backward.

[0150] See Figure 12As shown, in a specific example, the first grid region 252 is located between two adjacent second grid regions 254. One of the two adjacent second grid regions 254 has a first storage column 220A below it, and the other has a second storage column 220B below it. The first drive device 333 of the pick-up and drop robot 300 is configured to drive the transfer member (shown as belt 338 in the figure) to move in both forward and reverse directions, so that when the transfer member 337 moves in the forward direction, it unloads the stored object from the transfer device 330 to the target storage layer of the first storage column 220A, and when it moves in the reverse direction, it unloads the stored object from the transfer device 330 to the target storage layer of the second storage column 220B; or, when the transfer member 337 moves in the forward direction, it loads the stored object of the target storage layer of the first storage column 220A to the transfer device 330, and when it moves in the reverse direction, it loads the stored object of the target storage layer of the second storage column 220B to the transfer device 330.

[0151] One embodiment of this application also provides a warehousing method, which can be applied, for example but not limited to, the management equipment or pick-up and drop-off robot described above, the method comprising:

[0152] The retrieval robot equipped with a transfer device is controlled to move along the track system on top of the storage unit to the target position, so as to control the retrieval robot to lower the transfer device to the position corresponding to the target storage layer of the target storage column on the side of the target position, so as to transfer the stored objects between the target storage layer and the target storage layer.

[0153] Understandably, when the above method is applied to management equipment, the management equipment sends scheduling instructions to the pick-up and drop-off robot, which responds to the instructions and moves along the track system to the target location. The management equipment can select a suitable pick-up and drop-off robot from multiple robots for scheduling according to a preset strategy. Understandably, the management equipment may include one or more management terminals and / or one or more management servers. The scheduling instructions sent by the management equipment to the pick-up and drop-off robot are not limited to a single instruction, but may also be a combination of multiple instructions.

[0154] Understandably, when the above method is applied to a pickup robot, the pickup robot receives scheduling instructions sent by the management device and moves along the track system to the target position in response to the scheduling instructions.

[0155] The warehousing method of this application can be applied, for example, to the sorting process. Another embodiment of the warehousing method of this application includes:

[0156] SA10 controls a pick-up robot equipped with a transfer device to retrieve sorted goods at a transfer port located at the edge of a track system at the top of the storage unit.

[0157] In some embodiments, the objects to be sorted are transported to a predetermined feeding position at the top of the storage unit so that the sorted goods are separated from the objects to be sorted and placed into a pick-up robot at the transfer port.

[0158] In some embodiments, the objects to be sorted are transported to a predetermined feeding position on the ground control platform of the elevator, and the lifting conveyor that controls the elevator transfers the sorted goods separated from the objects to be sorted from the ground control platform to the transfer port. The predetermined feeding position on the ground control platform can be on the ground control platform or at a location next to the ground control platform.

[0159] SA20: Obtain the location information of the sorted goods to be delivered, including information on the target storage column and the target storage layer.

[0160] SA30 controls the transport robot to move along the track system to the target location adjacent to the target storage column.

[0161] SA40 controls the transport robot to lower the transfer device to the position corresponding to the target storage layer of the target storage column to the side of the target location.

[0162] In some embodiments, the transport robot can determine the descent distance of the transfer device based on the target storage layer information, and control the lifting device for raising and lowering the transfer device accordingly based on the descent distance.

[0163] In some embodiments, the retrieval robot can detect in real time whether it has reached the target storage layer during the descent. For example, it can detect preset marks corresponding to each storage layer set on the shelf or support during the descent, or detect preset marks on the cargo boxes of each storage layer, until the preset mark corresponding to the target storage layer is detected, then it is determined that the target descent position has been reached.

[0164] SA50 controls the transfer device to unload sorted goods to the target storage layer, for example, unloading a box containing sorted goods to the target storage layer, or unloading sorted goods into a box at the target storage layer.

[0165] The above embodiments will be further described below with reference to several specific application scenarios.

[0166] In one application, multiple orders can be aggregated into a single aggregate order. The types and / or quantities of goods required for the aggregate order are tallied to obtain the corresponding goods to be sorted. Then, the goods required for each order are sorted from the goods to be sorted into the corresponding order boxes. Correspondingly, another embodiment of the warehousing method of this application includes:

[0167] SB10. Based on multiple orders, determine the types and / or quantities of goods required.

[0168] SB20. According to the type and / or data of the required goods, the corresponding objects to be sorted are transported to the predetermined feeding position so that the sorted goods are separated from the objects to be sorted and placed into the pick-up and drop-off robot at the transfer port.

[0169] SB30: Obtain the target storage column and target storage layer corresponding to the target order that needs to be sorted among multiple orders.

[0170] SB40: Control the transport robot to move along the track system to the target location adjacent to the target storage column.

[0171] SB50: Control the transport robot to lower the transfer device to the position corresponding to the target storage layer of the target storage column to the side of the target position.

[0172] SB60, Control the transfer device to unload order boxes containing sorted goods to the target storage layer, or unload sorted goods to order boxes in the target storage layer.

[0173] In another application, single SKU items can be sorted into multiple order boxes. Correspondingly, another embodiment of the warehousing method of this application includes:

[0174] SC10: Transporting a sorting object containing multiple items of the same SKU to a predetermined feeding position so that the SKU items are sorted from the sorting object and placed into a pick-up robot at the transfer port.

[0175] SC20. Obtain information about the target storage column and target storage layer corresponding to the target order that requires the SKU product among multiple orders.

[0176] SC30 controls the transport robot to move along the track system to the target location adjacent to the target storage column.

[0177] SC40 controls the transport robot to lower the transfer device to the position corresponding to the target storage layer of the target storage column to the side of the target location.

[0178] SC50 controls the transfer device to unload SKU products into the order box at the target storage layer.

[0179] In another application, various types of goods can be sorted according to the goal of one SKU per box, multiple items of the same SKU per box, or one type of product per box. Correspondingly, another embodiment of the warehousing method of this application includes:

[0180] SD10 transports a sorting object containing multiple types of goods to a predetermined feeding position so that the sorted goods are separated from the sorting object and placed into the pick-up and drop-off robot at the transfer port.

[0181] SD20: Obtain the target storage column and target storage layer corresponding to the sorted object. The sorted object can be sorted goods or a sorting box containing sorted goods; for example, a sorted goods can be a single SKU.

[0182] SD30 controls the transport robot to move along the track system to the target location adjacent to the target storage column.

[0183] SD40 controls the transport robot to lower the transfer device to the position corresponding to the target storage layer of the target storage column to the side of the target location.

[0184] SD50 controls the transfer device to unload the sorted objects to the target storage layer or the target sorting box at the target storage layer.

[0185] For example, if the sorted item is a single SKU, the transfer device unloads the SKU to a target storage layer, which is used solely to store this SKU.

[0186] For example, if the sorted item is a single SKU, the transfer device unloads the SKU into a target sorting box in the target storage layer. This target sorting box is used to store goods of the same type or the same SKU.

[0187] For example, after sorting, the object is a sorting box containing the sorted goods, and the transfer device unloads the sorting box to the target storage layer.

[0188] In some embodiments, the track system includes a first track group extending along a first direction and a second track group extending along a second direction. The first track group and the second track group together form multiple grids on the top of the storage unit. The multiple grids form a first grid area and a second grid area. Multiple storage columns are distributed below the second grid area, and the storage columns have multiple storage layers.

[0189] In some embodiments, before controlling the pick-up robot with a transfer device to move along the track system on top of the storage unit to the target position on the track system, the method further includes:

[0190] Determine the target storage column corresponding to the stored object; and,

[0191] Based on the pre-stored map data of the track system, the corresponding data of multiple storage columns and grids in the second grid area, the target grid adjacent to the target storage column in the first grid area is determined. The target grid is the target position of the transport robot moving along the track system.

[0192] The map data of the orbital system includes distribution data of multiple grids, distribution data of the first and second orbital groups, distribution data of the first grid area, and distribution data of the second grid area.

[0193] In some embodiments, controlling a pickup robot equipped with a transfer device to move along a track system atop a storage unit to a target position on the track system includes:

[0194] The movement path of the pickup robot on the track system is determined based on the distribution data of the target grid adjacent to the target storage column in the first grid region, the first track group, and the second track group, as well as the current position of the pickup robot; and,

[0195] Control the pick-up and transport robot to move to the target grid according to the motion path.

[0196] In some embodiments, the warehousing method further includes controlling a retrieval robot to load or unload the stored objects at a transfer port located at the edge of the track system. By controlling the retrieval robot to load or unload the stored objects at the top of the storage unit, allowing the retrieval robot to move only within the top track system of the storage unit, the turnover rate of the retrieval robot can be improved, thereby increasing the efficiency of inventory or retrieval.

[0197] In some embodiments, the warehousing method further includes controlling a pickup robot to load or unload stored objects from above at a transfer port located at the edge of the track system. For example, when the pickup robot is configured as... Figures 6 to 10 In the structure shown, at the transfer port 256, the transfer mechanism of the pick-up and drop robot 300 retracts into the annular body of the movable base, and the stored object can be loaded into the transfer device or unloaded from the transfer device through the opening at the upper end of the annular body.

[0198] In some embodiments, the warehousing method further includes transferring the stored object between a pick-up robot at a sub-packaging port and a ground control panel or automated conveyor line.

[0199] In some embodiments, the warehousing method further includes: determining whether each storage location in the shelf has completed the loading or unloading of the corresponding stored object; if so, issuing a move shelf instruction; wherein the shelf is an integrated movable shelf formed by one or more storage columns. For example, after each storage location in the shelf has completed the placement of the corresponding stored object, a move shelf notification is issued to instruct operator 504 to move the shelf out for further processing; for example, in an application where the shelf is used as a seeding wall, the goods in the seeding wall are seeded into the corresponding order box; for example, in an application where the shelf stores order boxes, the shelf is moved to the verification and packaging area.

[0200] In some embodiments, the retrieval robot has a first drive wheel set that can move in the same direction as a first direction, and a second drive wheel set that can move in the same direction as a second direction; controlling the retrieval robot with a transfer device to move along a track system on top of the storage unit includes:

[0201] Control the first drive wheel set to leave the track system's track, and control the second drive wheel set to drive the pick-up and drop robot to move along the track in the second track set; or,

[0202] Control the second drive wheel group to leave the track of the track system, and control the first drive wheel group to drive the pick-up and transport robot to move along the track in the first track group.

[0203] In some embodiments, the method further includes: controlling the transport robot to charge the energy storage device of the transfer device during its movement along the track system. For example, when using the transport robot shown in the figure, during the movement of the transport robot along the track system, the first connecting end contacts the second connecting end, and the battery of the transport robot charges the energy storage device so that the energy storage device can provide sufficient power to the first drive device when the transfer device performs the next transfer, so that the first drive device can drive the transfer component to complete the transfer.

[0204] In some embodiments, the method further includes: determining the transfer direction of the transfer device based on the adjacency relationship between the target location and the target storage column, so as to control the transfer device to transfer the stored object between the target storage layer according to the transfer direction. For example, using... Figures 6 to 10 In the case of the transport robot shown in the figure, when the transport robot is located at mark 4 and the target storage column is 4_L (meaning the target position is adjacent to the right side of the target storage column), and the determined unloading direction is to the left, the drive roller can be rotated counterclockwise, and the drive belt can be moved to the left to unload the stored object into the target storage column 4_L. If the transport robot is located at mark 4 and the target storage column is 4_R (meaning the target position is adjacent to the left side of the target storage column), and the determined unloading direction is to the right, the drive roller can be rotated clockwise, and the drive belt can be moved to the right to unload the stored object into the target storage column 4_R.
