In this paper, a bionic self-energy high-altitude cleaning butler based on STM32 microcontroller is designed, combined with the cleaning function and self-energy design of bionic robots on the market, such a self-energy bionic high-altitude cleaning butler is produced. The steering gear control simulates the crawling action, and the lightweight design makes the robot easy to save and carry. The robot is inspired by the caterpillar. The realization of the caterpillar bionic function relies on the air pump to make the two suction cups adsorb in turn, and relies on the central steering gear to control the opening and closing rotation of the main body to realize various movements. At the same time, the steering gear at the suction cup can be turned at any time to adjust the forward direction of the robot. This function gives the robot high flexibility. The steering gear in the center of the robot controls the opening and closing and lifting of the two suction cups, which can cross a variety of obstacles, not only automatically cross the grid, clean the plane, curved glass exterior wall, but also remotely clean the designated area. Clean application field is broad, universal good. When cleaning the glass, one suction cup is fixed and adsorbed on the glass, and the other is wiped back and forth by the cleaning cloth beside the suction cup to achieve the cleaning effect. The robot can be used to clean a variety of smooth surfaces, such as: refrigerator surface, cabinet surface, blackboard surface, etc. The robot can replace manual cleaning, reducing the risk of manual cleaning the exterior walls of high-rise buildings, while saving energy and reducing carbon emissions. On this basis, considering that the working time of the robot may be relatively long, and the frequent charging of the battery may reduce the working efficiency of the robot, we have added a self-powered module on the above basis, using the cleanliness and renewability of solar energy. The power supply module has been modified and upgraded to increase the endurance, realizing dual-mode power supply and ensuring the sustainable operation of the robot.
