Design and implementation of an electromagnetic tracing intelligent vehicle based on STC32

This article takes the National College Student Smart Car Competition as the background and designs and produces an electromagnetic tracking car based on the STC32 chip. On the basis of not violating the competition rules, in order to improve the running stability and speed of the car, the hardware uses a DRV8701E driver board to drive the motor and a four-inductor arrangement to collect the inductance signal; the tracking algorithm uses a ratio algorithm and Fuzzy PID handles electromagnetic values. The experimental results show that the car has good tracking effect and strong anti-interference ability, and can successfully complete various requirements in smart car competitions.
