Users need to frequently bend over to pick up and store dirty clothes and manually hang them out to dry after washing, which is tedious and physically demanding. In addition, existing laundry baskets do not have mite removal and sterilization functions. Furthermore, sometimes users forget to check the pockets of their clothes, resulting in the presence of paper, plastic bags, documents, and other miscellaneous items in the pockets, which affects the washing machine and the washing effect. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and propose an intelligent full-process clothing management robot and its working method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The present invention discloses an intelligent full-process clothing management robot, comprising a mobile chassis, a robotic arm, a storage device, a clothes clamping device, a clothes drying device, a mite removal and sterilization device, a camera, and a connection device.

[0006] The storage device includes a housing, a clothes basket, an electrode array, a millimeter-wave radar array, and an NFC detection device. Both the housing and the clothes basket are cylindrical, with the clothes basket fixed inside the housing. The housing is driven to move by a mobile chassis. An electrode array is fixed to the inner wall of the housing, consisting of multiple electrodes arranged in an array. A millimeter-wave radar array and an NFC detection device are fixed to the bottom of the housing. The millimeter-wave radar array consists of multiple radar chips arranged in an array. The NFC detection device includes a transmitting coil and a receiving coil. An integrally formed mounting platform and a placement platform are provided on the outer edge of the top of the housing. A robotic arm is mounted on the mounting platform, and three integrally formed and spaced protrusions are provided on the placement platform.

[0007] The clothes clamping device includes a fixed base, an electric gripper, and an optical sensor, both of which are mounted on the fixed base. The clothes drying device includes a mounting frame and a spiral frame. The spiral frame and the mounting frame form a rotating pair and are driven to rotate by a drive motor. The spiral frame consists of an integrally formed spiral section and a U-shaped section. An opening 1 is provided on the mounting frame at the end of the spiral section away from the U-shaped section, and an opening 2 is provided at the position of the U-shaped section. The mite removal and sterilization device includes a fixed shell, ultraviolet lamps, a roller brush, a negative pressure fan, and a filter cartridge. Two ultraviolet lamps are fixed at a distance from the inlet of the fixed shell. The roller brush is located inside the fixed shell, forming a rotating pair with the fixed shell, and is driven to rotate by a drive motor. The inlet of the negative pressure fan is fixed to the outlet of the fixed shell through a dust suction channel, and the outlet of the negative pressure fan is fixed to the inlet of the filter cartridge.

[0008] The connection device includes an active connecting frame and three passive connecting frames. The active connecting frame is equipped with an electromagnet and a camera, and is driven to move by a robotic arm. Each passive connecting frame has a permanent magnet fixed on it and has a groove. The three passive connecting frames are respectively fixed to the fixed base, the housing of the negative pressure fan, and the mounting bracket. In the initial state, the clothes clamping device, the clothes drying device, and the mite removal and sterilization device are all placed on the placement platform, with each protrusion embedded in the groove of a passive connecting frame. The robotic arm, electric gripper, drive motor one, drive motor two, ultraviolet lamp, and negative pressure fan are all controlled by controller one. The signal output terminals of the camera, optical sensor, electrode array, millimeter-wave radar array, and NFC detection device are all connected to controller one, and controller one communicates with the washing machine and the mobile terminal.

[0009] Preferably, it also includes a stair-climbing device, which includes a catch, a base, a guide rail, a drive wheel assembly, and a guide wheel assembly. The catch and one end of the base form a sliding pair, and the catch is driven to rise and fall by a linear module mounted on the base. The other end of the base is fixed with a wheel cover, and a drive wheel assembly and several guide wheel assemblies are hinged on the base within the wheel cover. The drive wheel assembly consists of drive gears and driven wheels arranged at intervals, and the guide wheel assembly consists of two rollers arranged at intervals. A guide rail is provided between the drive gear and the driven wheel, and between the two rollers of each guide wheel assembly. The guide rail consists of an inclined section and horizontal sections integrally formed at both ends of the inclined section, and each guide rail forms a sliding pair with the wheel cover. A rack is fixed on the lower side of the guide rail located between the drive gear and the driven wheel. The driven wheel and each roller form a rolling friction pair with the corresponding guide rail. The drive gear meshes with the rack and is driven to rotate by a third drive motor. Both the third drive motor and the linear module are controlled by a second controller. A slot is provided on the lower surface of the mounting platform.

[0010] Preferably, the mobile chassis includes a frame and wheels. Multiple wheels are hinged on the frame and arranged at equal intervals. The frame is equipped with a laser radar and a positioning and navigation module. Each wheel is driven by its own servo motor. Each servo motor is controlled by a controller. The signal output terminals of the laser radar and the positioning and navigation module are connected to the controller.

[0011] Preferably, a humidity sensor and a fan are fixed to the inner wall of the clothes basket, and multiple ventilation holes are opened at the bottom of the clothes basket. The signal output terminal of the humidity sensor is connected to a controller, and the fan is controlled by the controller.

[0012] More preferably, the placement platform is equipped with a touch screen display, which is connected to the controller.

[0013] More preferably, the touch display screen is equipped with a voice interaction module.

[0014] The present invention discloses a working method for an intelligent end-to-end clothing management robot, as detailed below:

[0015] First, the dirty laundry is picked up. The robotic arm connects to the clamping device, and the camera identifies the location of each piece of dirty laundry. The moving chassis drives the frame to move the housing to the location of each piece of dirty laundry. The robotic arm drives the clamping device to move, so that the electric grippers of the clamping device can clamp the dirty laundry and send it into the laundry basket. When the electric grippers clamp the dirty laundry, the optical sensor identifies the material of the dirty laundry and sends the dirty laundry to the corresponding storage area in the laundry basket divided by partitions. When the dirty laundry enters the laundry basket, the electrode array detects whether there is metal in the dirty laundry, the millimeter-wave radar array detects whether there is paper or plastic sheet in the dirty laundry, and the NFC detection device detects whether there is an NFC card in the dirty laundry. When metal, paper, plastic sheet or NFC card is detected in the dirty laundry, the voice interaction module issues a foreign object alarm and notifies the user to pick it up.

[0016] After the dirty laundry is retrieved, the mobile chassis moves to the washing machine position. The washing machine door opens, the camera identifies the location of the dirty laundry in the basket, and the robotic arm drives the clamping device to move, causing the electric grippers of the clamping device to grab the dirty laundry in the basket and send it into the washing machine. The washing machine door closes, and the user sets the washing mode according to the fabric type. The washing machine then begins washing the dirty laundry. After washing is complete, the washing machine door opens, and the washing machine sends a washing completion command to the controller. The mobile terminal and voice interaction module issue a washing completion prompt, and the clothes begin to be dried. The drying process is as follows: the mobile chassis moves to the washing machine position, the robotic arm disconnects from the clamping device and connects to the drying device, and the user manually removes each garment from the washing machine and hangs it on the hanger. The user then manually hooks each hanger hook onto the spiral section of the auger through the opening. Simultaneously, the controller controls the drive motor to drive the auger to rotate intermittently. The spiral frame moves the spaced hangers towards the opening two. After the clothes are hung, the moving base moves the housing to the drying rod position. The camera identifies the position of the drying rod, and the robotic arm drives the clothes drying device to move the hangers and clothes so that the hanger hooks are above the drying rod. The controller controls the drive motor to drive the spiral frame to rotate forward, so that the hangers move sequentially to the U-shaped section of the spiral frame. When the hangers move to the U-shaped section of the spiral frame, as the spiral frame rotates, the hanger hooks detach from the U-shaped section and hang on the drying rod, completing the clothes drying process.

[0017] After the user determines that the clothes are dry, they send a collection and mite-removal / sterilization command to controller 1 via their mobile device. Each garment is then collected and sterilized sequentially. The process for each garment is as follows: the mobile chassis moves to the drying rod position; the camera identifies the drying rod's location; the robotic arm drives the drying device to move, positioning the U-shaped section to the side of the drying rod; controller 1 controls drive motor 1 to reverse the spiral frame, causing the U-shaped section to hook a hanger hook; the robotic arm drives the drying device to remove the hanger hook from the drying rod; the mobile chassis moves to the platform position; the camera identifies the platform's surface; the robotic arm drives the drying device to move the corresponding hanger, laying the clothes flat on the platform surface; controller 1 controls drive motor 1 to rotate the spiral frame clockwise, causing the hanger hook to detach from the U-shaped section; the robotic arm disconnects from the drying device. The connection is established and connected to the mite removal and sterilization device. The robotic arm moves the device, bringing the inlet of the fixed shell into contact with the surface of the garment. The robotic arm drives the device in a reciprocating motion, and during this motion, the ultraviolet lamps are activated for a preset time to kill live mites and bacteria on the garment. Then, controller one controls drive motor two to rotate the roller brush, which peels off mite carcasses and dander from the garment. Simultaneously, a negative pressure fan operates, transporting the peeled mite carcasses and dander through a suction channel to a filter cartridge for filtration. This process continues until the mite removal and sterilization of the garment is complete. The user manually hangs the garment in the wardrobe. The robotic arm then disconnects from the mite removal and sterilization device and connects to the clothes drying device. After completing the mite removal and sterilization of the last garment, the robotic arm disconnects from the mite removal and sterilization device and is no longer connected to the clothes drying device.

[0018] Preferably, when the electrode array detects whether there is metal in the laundry, each electrode is energized to generate an electromagnetic field. When metal is mixed in with the laundry, the eddy current effect of the metal changes the local magnetic field distribution, causing a change in current between adjacent electrodes. The presence of metal in the laundry is determined based on the generated current change signal. When the millimeter-wave radar array detects whether there is paper or plastic sheet in the laundry, since there is a difference in millimeter-wave reflectivity between clothing and paper or plastic sheet, when paper or plastic sheet is mixed in with the laundry, the millimeter-wave radar array captures the reflected signal and analyzes the difference in the intensity of the reflected signal to distinguish between clothing and paper or plastic sheet. When the NFC detection device detects whether there is an NFC card in the laundry, the active transmitting coil of the NFC detection device continuously transmits a signal. When an NFC card is mixed in with the laundry, the passive coil inside the NFC card generates an induced power and feeds back a signal. The receiving coil of the NFC detection device receives the feedback signal and determines that an NFC card is present.

[0019] Preferably, the connection process between the robotic arm and the clothes clamping device, clothes drying device, or mite-removing and sterilizing device is as follows: The electromagnet on the active connecting frame is energized to generate magnetic force. The robotic arm drives the active connecting frame to move the electromagnet closer to the driven connecting frame on the clothes clamping device, clothes drying device, or mite-removing and sterilizing device, causing the electromagnet to be magnetically attracted to the permanent magnet on the corresponding driven connecting frame. The robotic arm then drives the active connecting frame to move the entire clothes clamping device, clothes drying device, or mite-removing and sterilizing device upwards a predetermined distance via the electromagnet, the corresponding permanent magnet, and the corresponding driven connecting frame, causing the groove on the corresponding driven connecting frame to disengage from the corresponding protrusion. The process of connecting the robotic arm to the clothes clamping device, clothes drying device, or mite removal and sterilization device is as follows: The robotic arm drives the active connecting frame to move the entire clothes clamping device, clothes drying device, or mite removal and sterilization device to the initial position through the electromagnet, the corresponding permanent magnet, and the corresponding driven connecting frame, so that the corresponding boss is embedded in the groove of the corresponding driven connecting frame. The electromagnet on the active connecting frame is de-energized, the magnetic force disappears, and the connection between the electromagnet and the permanent magnet on the corresponding driven connecting frame is broken, thereby completing the disconnection of the robotic arm from the clothes clamping device, clothes drying device, or mite removal and sterilization device.

[0020] Preferably, both ends of each guide rail of the stair climbing device are fixed to the wall. When climbing the stair, the movable chassis drives the housing to move to the base position of the stair climbing device, so that the slot on the lower surface of the mounting platform is aligned with the latch of the stair climbing device. The linear module drives the latch to rise a preset distance, so that the latch is inserted into the slot, and drives the mounting platform and the housing to rise. The movable chassis is no longer in contact with the ground. The controller two controls the drive motor three to drive the drive gear to rotate. The drive gear meshes with the rack. The base drives the housing to move along each guide rail until it reaches the corresponding floor. The linear module drives the latch to lower the housing. The latch returns to its original position and disengages from the slot. The movable chassis contacts the ground, completing the stair climbing operation.

[0021] The present invention has the following beneficial effects:

[0022] 1. This invention offers diverse functions. Through the coordinated operation of multiple modules—sensing, execution, control, and interaction—it efficiently achieves automatic collection of clothing, debris identification, intelligent washing, automatic drying, and mite removal and sterilization, with a high degree of intelligence. Specifically, this invention uses a camera to identify the location of dirty clothes, and a moving chassis drives the housing to move a robotic arm to the location of the dirty clothes. The robotic arm then drives the clamping device to move, causing the electric grippers of the clamping device to clamp the dirty clothes and deliver them to the laundry basket, thus achieving automatic collection of clothing. The clamping device is equipped with an optical sensor that can identify the material of the clothing for selecting the subsequent washing mode. Furthermore, the housing is equipped with an electrode array and millimeter-sized... The invention employs a radar array and an NFC detection device to detect metal, paper or plastic flakes, and NFC cards in dirty clothes, respectively, preventing them from affecting the subsequent washing process and washing results, thus achieving debris identification on the clothes. Furthermore, the invention communicates with the washing machine; the moving chassis drives the robotic arm to the washing machine's position, and the robotic arm drives the clamping device to move, causing the electric grippers to clamp the dirty clothes in the clothes basket and send them into the washing machine. The washing machine then uses the received washing mode to wash the clothes, thus achieving intelligent washing and delivery. After washing, the user hangs the clothes on the hangers and hooks the hanger hooks onto the spiral section of the spiral rack in the drying device connected to the robotic arm. Simultaneously, a drive motor drives the spiral frame to rotate intermittently forward, causing each hanger to move intermittently towards the U-shaped section closest to the spiral frame. The moving chassis drives the robotic arm to the drying rod position. The robotic arm drives the drying device to move, and simultaneously, a drive motor drives the spiral frame to rotate forward, causing the moving chassis to move along the drying rod, causing each hanger hook to move sequentially onto the U-shaped section and detach sequentially, hanging on the drying rod. After the clothes are dried, the robotic arm drives the drying device to move until the U-shaped section is located to the side of the drying rod. Then, a drive motor drives the spiral frame to rotate in reverse, causing the U-shaped section to hook the hanger hooks and remove them from the drying rod, thus achieving automatic clothes drying. Each time a hanger is removed... The mobile chassis drives the robotic arm to the platform position. The robotic arm then drives the clothes drying device to move, laying the clothes on the hangers flat on the platform. The first drive motor drives the spiral frame to rotate forward, causing the U-shaped section to disengage from the hanger hooks. Then, the robotic arm disconnects from the clothes drying device and connects to the mite removal and sterilization device, driving the device to move back and forth along the surface of the clothes. During this reciprocating movement, the ultraviolet lamp of the mite removal and sterilization device first kills live mites and bacteria on the clothes. Then, the second drive motor drives the roller brush to rotate, peeling off the mite corpses and dander from the clothes. The negative pressure fan operates, transporting the peeled mite corpses and dander through the dust suction channel to the filter cartridge for filtration, thereby achieving mite removal and sterilization of the clothes.

[0023] 2. The modular design of the robotic arm with the clothes clamping device, clothes drying device and mite removal and sterilization device in this invention facilitates independent repair or replacement, reduces maintenance costs, and the robotic arm can be connected to the clothes clamping device, clothes drying device or mite removal and sterilization device through a magnetic connection device, which enables quick replacement of the end effector.

[0024] 3. This invention also has the ability to move across floors, facilitating flexible movement in multi-story residential buildings. Specifically, this invention uses a stair-climbing device installed on the side of the staircase. To climb the stairs, the moving chassis drives the housing to move to the base position of the stair-climbing device. The linear module on the base drives the latch to rise, so that the latch is inserted into the slot of the mounting platform on the housing, and drives the mounting platform and housing to rise, so that the moving chassis is no longer in contact with the ground. The drive motor drives the drive gear to rotate, and the drive gear meshes with the rack on the corresponding guide rail. The base moves along each guide rail, so that the base drives the housing to move along the guide rail, thereby realizing the stair-climbing function. Attached Figure Description

[0046] The present invention discloses a working method for an intelligent end-to-end clothing management robot, as detailed below:

[0047] First, the dirty laundry is picked up. The robotic arm 3 is connected to the clamping device 4. The camera 8 identifies the location of each piece of dirty laundry. The controller 1 controls each servo motor to synchronously drive each wheel, moving the frame and housing 2-1 to the location of each piece of dirty laundry. The robotic arm 3 drives the clamping device 4 to move, so that the electric gripper of the clamping device 4 clamps the dirty laundry and sends it into the laundry basket. When the electric gripper clamps the dirty laundry, the optical sensor identifies the material of the dirty laundry and sends the dirty laundry to the corresponding storage area. When the dirty laundry enters the laundry basket, the electrode array 2-3 detects whether there is metal in the dirty laundry, the millimeter-wave radar array 2-4 detects whether there is paper or plastic sheet in the dirty laundry, and the NFC detection device 2-5 detects whether there is an NFC card in the dirty laundry. When metal, paper, plastic sheet or NFC card is detected in the dirty laundry, the voice interaction module issues a foreign object alarm and notifies the user to pick it up. In this system, when electrode array 2-3 detects the presence of metal in the laundry, each electrode is energized to generate an electromagnetic field. When metal is mixed in with the laundry, the eddy current effect of the metal changes the local magnetic field distribution, causing a change in current between adjacent electrodes. The presence of metal in the laundry is determined based on the generated current change signal. When millimeter-wave radar array 2-4 detects the presence of paper or plastic sheets in the laundry, due to the difference in millimeter-wave reflectivity between clothing and paper or plastic sheets, when paper or plastic sheets are mixed in with the laundry, millimeter-wave radar array 2-4 captures the reflected signal and analyzes the difference in the intensity of the reflected signal to distinguish between clothing and paper or plastic sheets. When NFC detection device 2-5 detects the presence of NFC cards in the laundry, the active transmitting coil of NFC detection device 2-5 continuously emits a low-frequency signal. When an NFC card is mixed in with the laundry, the passive coil inside the NFC card generates an induced power and feeds back a signal. The receiving coil of NFC detection device 2-5 receives the feedback signal and determines that an NFC card is present.

[0048] After completing the dirty laundry retrieval, the mobile chassis 1 plans its path to the washing machine location via the positioning and navigation module. The controller controls each servo motor to synchronously drive the frame and move the housing 2-1 to the washing machine location. The washing machine door opens (either opened by the user, by the clamping device 4, or automatically). The camera 8 identifies the location of the dirty laundry in the laundry basket. The robotic arm 3 drives the clamping device 4 to move, so that the electric grippers of the clamping device 4 clamp the dirty laundry in a single storage area of ​​the laundry basket and send it into the washing machine (for convenience, it can also be set to send the dirty laundry from multiple or all storage areas into the washing machine). The washing machine door closes (either closed by the user, by the clamping device 4, or automatically). The user sets the washing mode for the clothes according to the material of the clothes via a mobile terminal or touch screen. The controller sends the washing mode to the washing machine, and the washing machine begins washing the dirty laundry.

[0049] After the washing machine finishes washing the dirty clothes, the washing machine door opens, and the washing machine sends a washing completion command to the controller. The mobile terminal and voice interaction module issue a washing completion prompt, and the clothes begin to be dried. The drying process is as follows: the mobile chassis 1 plans its path to the washing machine position through the positioning and navigation module. The controller controls each servo motor to synchronously drive each wheel, moving the frame and housing 2-1 to the washing machine position. The robotic arm 3 disconnects from the clothes clamping device 4 and connects to the clothes drying device 5. The user manually takes each garment out of the washing machine and hangs it on the hanger, and manually hooks each hanger hook onto the spiral section of the spiral frame 5-2 through the opening 1. At the same time, the controller controls the drive motor to drive the spiral frame 5-2 to rotate intermittently forward, and the spiral frame 5-2 drives the spaced hangers. The machine moves towards the direction of opening two until all clothes in the washing machine are removed. The moving chassis 1 plans its path to the drying rack position through the positioning and navigation module. The controller controls each servo motor to synchronously drive the frame and move the housing 2-1 to the drying rack position. The camera 8 identifies the position of the drying rack. The robotic arm 3 drives the clothes drying device 5 to move each hanger and each piece of clothing, so that each hanger hook is positioned above the drying rack. The controller controls the drive motor to drive the spiral frame 5-2 to rotate forward, so that each hanger moves sequentially to the U-shaped section of the spiral frame 5-2. When the hanger moves to the U-shaped section of the spiral frame 5-2, as the spiral frame 5-2 rotates and the moving chassis 1 moves along the drying rack, each hanger hook disengages from the U-shaped section and hangs on the drying rack, thus realizing the drying of clothes.

[0050] After the user determines that the clothes are dry, they send a collection and mite-removal / sterilization command to the controller via a mobile device. Each garment is then collected and sterilized sequentially. The process for each garment is as follows: the mobile chassis 1 plans its path to the drying rack using a positioning and navigation module; the controller controls the servo motors to synchronously drive the wheels, moving the frame and housing 2-1 to the drying rack position; the camera 8 identifies the drying rack position; and the robotic arm 3 drives the drying device 5 to move, positioning the U-shaped section to the side of the drying rack. The controller 1 controls the drive motor 1 to drive the spiral frame 5-2 to reverse, causing the U-shaped segment to hook a clothes hanger hook. The robotic arm 3 drives the clothes drying device 5 to remove a clothes hanger hook from the drying rod. The moving chassis 1 plans its movement path to the platform position through the positioning and navigation module. The controller 1 controls each servo motor to synchronously drive the frame housing 2-1 to move to the platform position. The camera 8 identifies the position on the platform surface. The robotic arm 3 drives the clothes drying device 5 to move the corresponding clothes hanger, so that the clothes on the hanger are laid flat on the platform surface. The controller 1 controls the drive motor 1 to reverse the spiral frame 5 to hook a clothes hanger hook. The controller 1 controls the drive motor to move the spiral frame 5 to the platform position. The controller 1 controls the spiral frame 5 to the platform position. The controller 1 controls the spiral frame 2-2 to move the spiral frame 5 to the platform position. The controller 1 controls the spiral frame 2-2 ... The first drive unit rotates the spiral frame 5-2 clockwise, causing the clothes hanger hook to detach from the U-shaped section. The robotic arm 3 disconnects from the clothes drying device 5 and connects to the mite-removing and sterilizing device 6. The robotic arm 3 moves the mite-removing and sterilizing device 6, bringing the entrance of the fixed shell 6-1 in the device to the surface of the clothing. The robotic arm 3 drives the device to move back and forth, and during this back-and-forth movement, each ultraviolet lamp 6-2 is activated for a preset time to kill live mites and bacteria on the clothing. Then, the controller controls the second drive motor to... The rotating brush 6-3 removes mite carcasses and dander from the clothing. Simultaneously, the negative pressure fan 6-5 operates, transporting the removed mite carcasses and dander through the suction channel to the filter cartridge 6-6 for filtration until the mite removal and sterilization of the clothing is completed. The user then manually hangs the clothing in the wardrobe. The robotic arm 3 disconnects from the mite removal and sterilization device 6 and connects to the clothes drying device 5. After completing the mite removal and sterilization of the last garment, the robotic arm 3 disconnects from the mite removal and sterilization device 6 and is no longer connected to the clothes drying device 5.

[0051] The connection process between the robotic arm 3 and the clothes clamping device 4, clothes drying device 5, or mite removal and sterilization device 6 is as follows: the electromagnet on the active connecting frame is energized to generate magnetic force. The robotic arm 3 drives the active connecting frame to move the electromagnet towards the driven connecting frame on the clothes clamping device 4, clothes drying device 5, or mite removal and sterilization device 6, so that the electromagnet and the permanent magnet on the corresponding driven connecting frame are attracted by magnetic force. The robotic arm 3 drives the active connecting frame to move the entire clothes clamping device 4, clothes drying device 5, or mite removal and sterilization device 6 upward a preset distance through the electromagnet, the corresponding permanent magnet, and the corresponding driven connecting frame, so that the groove of the corresponding driven connecting frame is disengaged from the corresponding boss, thereby completing the connection between the robotic arm 3 and the clothes clamping device 4, clothes drying device 5, or mite removal and sterilization device 6.

[0052] The disconnection process between the robotic arm 3 and the clothes clamping device 4, clothes drying device 5, or mite removal and sterilization device 6 is as follows: The robotic arm 3 drives the active connecting frame to move the entire clothes clamping device 4, clothes drying device 5, or mite removal and sterilization device 6 to the initial position through the electromagnet, the corresponding permanent magnet, and the corresponding driven connecting frame, so that the corresponding boss is embedded in the groove of the corresponding driven connecting frame. The electromagnet on the active connecting frame is de-energized, the magnetic force disappears, and the connection between the electromagnet and the permanent magnet on the corresponding driven connecting frame is disconnected, thereby completing the disconnection between the robotic arm 3 and the clothes clamping device 4, clothes drying device 5, or mite removal and sterilization device 6.

[0053] In this system, a stair-climbing device is installed on the side of the staircase. Both ends of the guide rails 9-3 of the stair-climbing device are fixed to the wall. When climbing the stairs, the mobile chassis 1 plans its path to the base position of the stair-climbing device through the positioning and navigation module. Controller 1 controls each servo motor to synchronously drive each wheel, moving the frame and housing 2-1 to the base position of the stair-climbing device, so that the slot on the lower surface of the mounting platform is aligned with the latch 9-1 of the stair-climbing device. The linear module drives the latch 9-1 to rise a preset distance, so that the latch 9-1 is inserted into the slot, and drives the mounting platform and housing 2-1 to rise. All wheels are out of contact with the ground. Controller 2 controls the drive motor 3 to drive the drive gear to rotate. The drive gear meshes with the rack, and the base 9-2 moves the housing 2-1 along each guide rail until it reaches the corresponding floor. The linear module drives the latch 9-1 to descend, and the latch 9-1 returns to its original position, disengaging from the slot. All wheels are in contact with the ground, completing the stair-climbing operation.
