Design and Implementation of the Maze Patrolling with Three Branch Roads by the Smart Car Based on 51 Single Chip Microcomputer

Abstract

With the rapid development of technology, the application of artificial intelligence technology in life is becoming more and more extensive, and intelligent robots play an important role in life. A smart car that can carry out the maze patrolling of three branch roads is designed. This smart car is mainly controlled by the STC89C52 chip and driven by the L298N chip. In this work, the ground information is firstly collected and transformed by the 4-channel TCRT5000 infrared reflection sensor module. Then, TCRT5000 infrared reflection sensor module converts the collected ground information into digital signals and transmits them to the main control chip. Finally, the recognition of the road and the control command such as go forward, turn left and turn right can be implemented through the main control chip. The power system of the smart car is composed of the L298N motor drive module and two DC motors. The main control chip controls the rotation speed and steering of the two DC motors separately, and uses the principle of differential steering to achieve left and right steering. The design uses sensor technology and uses C language for programming, so that the car automatically recognizes the three-way road. This design can be used in driverless vehicles and artificial intelligence related fields.
