The black line's detection principle is that the infrared emitter tubes emit light to the pavement, the infrared light encounters the white bottom to be reflected, the receiving tube receives the reflected light, the output low level after the Schmitt trigger is shaped, and when the infrared light encounters the black line, the receiving tube does not receive the
