Laser-based servo detection system for smart car

In this paper, A laser-based servo detection system and its servo control algorithm are proposed to overcome the disadvantage that smart car based on fixed sensors could easily lose road information when tracking at a high speed. To fix a laser sensor on a servo actuator, MCU (Micro Controller Unit) can process the feedbacks of the sensor and then control the servo to adjust the direction of the sensor to detect road. Thus the closed-loop control ensures that the system can track the road automatically. Experiments in this paper show that smart cars based on servo detection system can achieve lower tracking error and a higher average speed when compared to those based on fixed sensors. Therefore, the laser-based servo detection system not only improves smart car´s speed but also promotes its systemic stability.
