Abstract
Line follower robot constitutes one of the very crucial characteristics of robotics. A robotic system is the intelligent system that can follow whether it's a black-on-white contrasting colored surface or vice versa. The code is programmed in such a way that the robot runs automatically in alignment with the line. The robot designates the line with the help of optical sensor arrays, which enables it to keep its course. The ensemble of four sensors provides accurate and adaptable movement. The wheels on the machine are governed by the rotation of DC motors having gear box. The Atmega32-based Arduino device is utilized to operate and incorporate algorithms that govern motor rotational speed, enabling the device to commute all along the line flawlessly. The objective of this research is to apply the line-following algorithms and regulate the robot's direction and move through proper calibration of the control factors, resulting in better results. Also, an added LCD module is added to indicate by visualizing the trip distance of the system. The system can be used as a load carrier in factories, industries, etc.
