The threaded tube 855 is threadedly connected to the end actuator 7, and different functional modules can be quickly replaced. It can also be expanded and installed such as an air detection module, which is used to detect indoor air quality and move to detect different areas, realizing multiple uses of one machine, enriching the functional connotation of home automation services, and meeting the diverse life needs of families.

[0053] Furthermore, the present invention is designed and applied in a smart home. The mounting plate 1 is mounted on the indoor ceiling. The length of the mounting plate 1 can be customized according to the size of the indoor space. The general standard length is 3-5 meters, which can be spliced ​​and extended. The fixed tube 55 is rotated. The fixed tube 55 rotates on the outer surface of the screw rod 54 and moves downward. When the fixed tube 55 moves downward, it drives the fixed seat 56 connected to its bearing to move downward. The fixed seat 56 drives the mechanical arm body 6 installed therewith to move downward. The mechanical arm body 6 drives the end effector 7 to move through the mounting structure 8, so that the size of the indoor space can be customized according to the size of the indoor space. The height of the mounting structure 8 is adjusted according to the height of the mounting structure 8, and the driver 51 is used to drive the wheel 52 to rotate. The wheel 52 is driven by the DC motor in the driver 51, and the motor power is 30-50W, so that the driver 51 and the wheel 52 can move quickly and smoothly on the hanging track 4. The trolley is equipped with a power module to provide power for the entire robot arm body 6. The power supply adopts a rechargeable lithium battery with a capacity of 50-100Ah, which can meet the continuous operation of the robot arm body 6 for 4-8 hours. The wheel 52 moves in the hanging track 4, so that it can be moved as needed;

[0054] The robot arm body 6 is connected by multiple joints, including shoulder joints, elbow joints and wrist joints. The shoulder joint adopts a rotary joint design, which can achieve 360-degree horizontal rotation. The wrist joint has rotation and pitch functions, and the rotation angle is 360 degrees. The joints of the robot arm body 6 are connected by high-strength alloy steel shafts. Precision bearings are installed at the connection between the shaft and the joint to reduce friction resistance and improve the flexibility and accuracy of joint movement.

[0055] Start the motor 825, the output end of the motor 825 drives the screw 11 fixedly connected thereto to rotate, the screw 11 drives the two displacement frames 12 threadedly connected thereto to move in opposite directions, the displacement frame 12 can drive the arc plate 13 fixedly connected thereto to move when it moves, the arc plate 13 can drive the slider 15 fixedly connected thereto to slide in the limiting groove 824 when it moves, thereby improving the displacement stability of the arc plate 13, when the arc plate 13 moves, it can drive the limiting rod 14 fixedly connected thereto to move out of the insertion hole 83 and the connecting hole 853, pull the second fixing plate 851, the second fixing plate 851 drives the insertion tube 852 fixedly connected thereto to slide in the insertion slot 84 and move out of the insertion slot 84, and then the end effector 7 and the threaded tube 855 are disassembled, so that they can be quickly replaced according to different functional requirements;

[0056] A variety of sensors are integrated on the robot body 6. The visual camera 9 is installed on the head of the robot arm. It uses a high-definition CMOS camera with a resolution of 1080p-4K and a field of view of 60-120 degrees to identify target objects, environmental features and obstacles. After the robot body 6 is started, the device first scans the indoor environment to obtain point cloud data of the surrounding environment, and combines the image information captured by the visual camera 9 to build an indoor environment map through the built-in SLAM algorithm to determine the position coordinates of the robot body 6 itself in the environment. During operation, the device monitors the surrounding obstacle information in real time, and the visual camera 9 continuously tracks the target object;

[0057] After the robot body 6 is started, it first obtains the point cloud data of the surrounding environment, and combines it with the image information captured by the visual camera 9 to build an indoor environment map, determine the position coordinates of the robot body 6 itself in the environment, and monitor the surrounding obstacle information in real time during operation, and the visual camera 9 continuously tracks the target object;

[0058] After receiving the user's instruction, the optimal movement path of the robot arm body 6 is planned according to the environmental information and the position of the target object. For example, if the instruction is to grab the water cup on the table in the living room, the device will calculate the collision-free path from the current position to the target position, and then move the trolley 5 to the appropriate position along the suspension track 4. Then, the joints of the robot arm body 6 move in sequence, adjust the posture of the end effector 7, align the grabbing module with the water cup, and finally grab the water cup and move it to the designated position according to the planned path. In the cleaning task, the end effector 7 is replaced with the cleaning structure, the mobile trolley 5 drives the robot arm body 6 to move to the area to be cleaned, and the wrist joint adjusts the angle of the cleaning structure so that the brush head contacts the cleaning surface. At the same time, the robot arm moves according to the preset cleaning trajectory to complete the cleaning work.

[0059] The device is controlled by a microprocessor, using a high-performance ARM chip with an operating frequency of 1-2GHz. The robot arm body 6 can be linked with other devices in the smart home system, such as connecting with a smart speaker to achieve voice interaction, and the user can directly issue commands through voice; linked with the smart door lock, when it detects that the owner has returned home, it automatically performs welcome tasks, such as turning on lights, playing music, etc. At the same time, the robot arm body 6 also has self-diagnosis and fault alarm functions. When a sensor or motor fails, it can send fault information to the user in time, and try to automatically repair or enter safety protection mode;

[0060] With its flexible suspension track 4 and the design of the robot arm body 6, the device can quickly move and adjust its posture in the indoor space, and can complete tasks such as large-area window cleaning and multi-area item sorting and storage in a short time. Its cleaning speed can be increased by 3-5 times compared with traditional manual cleaning methods, and the item sorting efficiency is increased by 2-4 times; in terms of item delivery, it can quickly deliver items between different rooms and different heights according to user instructions, avoiding the tedious process of manual handling, such as delivering food and drinks in family gatherings. The overall service efficiency is significantly improved compared with traditional methods, which can greatly save manpower and time costs.
