High accuracy line following intelligent car based on infrared sensor

Abstract

This research aims to describe the design and construction of a line-following intelligent automobile using the TM4C123GH6PZ microcontroller as the central processing unit. The vehicle uses two MG310P20_7 motors, one motor driver circuit and a 12-gray sensor for propulsion, motor control and line detection. The sensors made the high-accuracy angler movement in tests, the vehicle is 91.85% stabile to follow the line, taking an average of 3.44 seconds to complete a 3-meter road. Therefore, this concept demonstrates how infrared sensors and sophisticated control algorithms can be used to be more stable in creating driverless vehicles.
