The MK60FN1M0VLQ15 32bit microcontroller with cortex-M4 core is designed as the core control unit (MCU). The 0V7725 digital camera is used to extract the runway realtime image. With the Omron rotary encoder as the speed detection device, the brushless DC motor is used as the transmission, Steering control with a steering gear and 7.2 V lithium battery constitute the entire motion control system. In the software design, the slope of the image center line is used to find the best path. The PD control algorithm is used to deal with the steering gear and the PID control algorithm to adjust the speed of the DC motor. Thus completing the entire system of closedloop control.
