Abstract :
Abstract: In this article, a new approach is presented to receive information and recognize colored lines by CNY70 transmitter and receiver sensors in wheeled line following robots. Here (racing track), the robot must follow a line with a width of approximately 1.8 cm, which can be black with a white background or vice versa with colored lines and different elements, and after passing the obstacles, it must achieve the necessary goals. These types of robots are mostly laboratory-based, and many scenarios and technologies can be implemented on them and after testing and if the results are obtained, they can be used in commercial, industrial, medical, etc. Those that bring patients to the intended units in hospitals using specified lines can be mentioned. From the observed laboratory results, due to the use of cheap sensors and the reduction of used electronic parts (elimination of op amp and potentiometer) with the same number of sensors, this method reduces energy consumption by 30% compared to other methods and significantly reduces costs. It makes more and more useful use of microcontroller bases.
