The design of?the lower computer system?is a 52 microcontroller?as the control core,?the use of?CPU?model for STC12C5A60S2,?with the?sensor has?an ultrasonic sensor HC-SR04,2?infrared?tracking sensor?LM393,?and a?combination of?2?motor drive and?power supply?module?in one?module,?the?dual motor drive?module adopts the?new original L298Nthe driver chip,?using the 5V?voltage?regulator module?block AMS1117-5V?high precision regulator,?and?steering Futaba?S3003 used to?the full range of?distance perception,?control mechanism of?car?is composed of two DC motors?and L298N driver?chip consists of?two drive?four?wheel car,?so?DC motor?can be directly controlled?by the STC12C5A60S2?input port?IO port. Based sensor design of car, simple structure, low cost,
