[0015] Example: The following is in conjunction with the appendix Figure 1-2The present invention will be described in further detail below.

[0016] The flying painting and rust removal robot consists of a base unit 10 and a flying unit 20. The electric cable reel 12 on the base unit 10 is connected to the power interface of the flying unit 20, providing power to the flying unit 20 via the cable. The flying unit 20 can rise away from or descend towards the base unit 10. Two vertical lidar sensors 60 are installed on the standby platform 11 of the base unit 10, and corresponding lidar sensors 60 are located at the bottom of the flying unit 20. The vertical lidar sensors 60 on the base unit 10 and the lidar sensors 60 at the bottom of the flying unit 20 sense each other, ensuring not only smooth takeoff and accurate landing of the flying unit 20, but also assisting in autonomous attitude adjustment during operation, ensuring it does not deviate from its position and maintaining a relatively vertical state between the base unit 10 and the flying unit 20. This is because the flying unit 20's power is delivered via cable, and this design facilitates cable retraction and deployment. Simultaneously, two tilt sensors 22 are installed on the top of the flying unit 20 to maintain its balance during movement.

[0017] The flight unit 20 is equipped with six lift fans 21 within its open space, capable of basic ascent, descent, and hovering maneuvers. The fans' output angle is adjustable, allowing for additional movements such as forward, backward, and left / right shifting, enhancing its flexibility. Inside the cabinet with a roller shutter door, the flight unit 20 houses a dedicated multi-axis robotic arm 30. This robotic arm 30 can move freely within a fixed range along the X, Y, and Z axes, including but not limited to extending and retracting the cabinet and full-angle rotation. A detachable laser gun head for rust removal can be mounted on the robotic arm 30, which can also be replaced with a specially designed paint spray gun, switching between rust removal and painting functions to meet operational needs. Eight lidar sensors 60 and scanning lenses 70 are evenly and rationally arranged around the flight unit 20 according to its casing dimensions. These components work together to scan the work site in real time, and the flight unit 20 autonomously plans the work grid area based on the scene. The lift fans 21 and the gantry robotic arm 30 then operate autonomously according to the grid area's location. The lidar sensors 60 and scanning lenses 70 are essential hardware support. The flight unit 20 is also equipped with necessary electronic components, such as a laser generator 23 that supports laser gun head operation, a transformer 50 for use with cables, a water cooler 24 for enhanced heat dissipation, a flight control system 40 with six motor drivers, and necessary wires and connectors. The flight control system 40 is equipped with AI intelligent algorithms, which can not only process and respond to collected information such as environmental conditions and real-time equipment status, but also automatically plan the operation route, area and steps, which is the key to autonomous operation. It can also intervene and control the individual lift fan 21 through the motor drivers to flexibly operate the attitude and movement of the flight unit 20.

[0018] The base unit 10 is designed as a vehicle structure, with four drive wheels mounted on the chassis, capable of carrying the flight unit 20 or moving short distances independently. An electric cable reel 12 with wound cables is located on the area outside the standby platform 11 of the base unit 10, surrounded by guardrails. Optionally, a driving control box 13 is installed at this end to control the movement, power supply, and laser positioning of the base unit 10. Eight lidar sensors 60 and scanning lenses 70 are also correspondingly installed around the base unit 10, primarily for confirming road conditions and preventing collisions with obstacles. The base unit 10 operates fully automatically, moving with the flight unit 20 from the current grid area to the next subdivided grid area as needed. An electrical storage box is located at the bottom of the base unit 10, including a built-in backup emergency battery pack 14, a transformer 50, and a drive controller. A tool storage box is also provided at the bottom of the base unit 10 for storing work tools, emergency fire extinguishers, and other equipment. The base unit 10 is connected to an external AC 380V mains power supply. The main power supply is transformed to 600V by the transformer 50 inside the base unit 10 and transmitted to the transformer 50 of the flight unit 20 via cable. The voltage is then boosted to 800V and the DC 12V voltage required by the flight control system 40. In the event of a sudden interruption of the external power supply, the backup emergency battery pack 14 built into the base unit 10 will supply power to the transformer 50 with a millisecond-level response speed to ensure that the flight unit 20 can land safely.

[0019] It should be noted that this specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
