The Cleaning Robot Working at Height Final Based on the Principle of Negative Pressure Absorbtion

Abstract

To help people clean the window at high altitudes, we design a window cleaning robot. The robot should be able to walk on most glass walls according to designated routes. To achieve uniform speed, turning, automatic speed control and other functions, we firstly used C51 programming technology to control speed. Then, in order to improve the performance, we used STM32F103zet6 programming and we used PID algorithm. For the hardware, we used DC motor and air pump to achieve negative pressure for the purpose of walking along the window stably. Compared with the cleaning robot sold in the market nowadays, our robot can clean a vertical surface. This paper gives you the hardware and software design of this new robot.
