| Abstract: | Based on two microcontrollers, 89C52 and 89C2051, the model vehicle can race intelligently by detecting black lines on the ground. Reflecting-infrared sensors are applied to detect black lines, and photoelectric switchers are used in speed and distance detection. By introducing PWM to the system, we are able to control motor revolving speed dynamically and precisely. And one of the most striking features of the design is its software algorithm which enables the vehicle to stop at the final line with high accuracy. |
