Design and Implementation of a Two-Car Tracking System

This paper designs a two-car tracking system. The leading car is composed of TI MCU MSP430F5529, gray sensor S301D, motor drive, DC reduction motor and Bluetooth module. On the basis of the above, an ultrasonic module is added to the following car to detect the distance between the two cars. The leading car and the following car communicate with each other through the Bluetooth module, they all use the gray sensor S301A to detect the runway position information and transmit it to the microcontroller. The two cars carry out communication and ranging according to different requirements of the system, program in C language, and continuously optimize the algorithm. At the same time, by optimizing the gray sensor position of the two cars and the structure of the two cars, they can jointly to achieve multiple tracking functions.
