Students get to learn about how sensors work and are also taught how to make various sensors of their own and integrate them with an Arduino board to implement various algorithms to build an efficient line follower, capable enough of participating in the various robotic events going around. This workshop brushes your skills in Analog Electronics and introduces you to the exciting world of Autonomous Robotics after going through a brief introduction to programming in Arduino. The design process would allow the robot to detect white and black surfaces, travel along a 3 m straight line with a constant acceleration, and permit acceleration with a smartphone sensor by the Phyphox application. Hence, the processor is going to decide the proper commands and then it sends them to the driver and thus the path will be followed by the line follower robot. This research aims to develop a simple line-follower robot with constant acceleration motion as an educational tool. The path may be visible like a black line on a white surface or may be reverse of that or it can be. After that, the data is transmitted to the processor by specific transition buses. The line follower is an autonomous robot that detects and follows a line. This project presents the line follower robot called The Bug built by our team Resistor 2K20 for RoboTEC 2020 student competition. In this project, LM3S811 which is ARM cortex-3 based microcontroller is chosen as the main controller to react towards. This printed circuit acts as the chassis of the robot. Unlike the previous one, I have made the design of the printed circuit using EasyEDA. Definitely, this kind of robot should sense the line with its infrared ray (IR) sensors that installed under the robot. This paper presents the development of a line follower wheeled mobile robot. This is my second Line Follower Robot (Version 4). Generally, the path is predefined and can be either visible like a black line on a white surface with a high contrasting color or it can be invisible like a magnetic field. Thesecond one is that the completion time should be as shortas possible. The rstrequirement is that the robot should complete the track. A line follower robot is a mobile machine that can detect and follow the line drawn on the floor. the controller algorithm for a differential wheeled robot to follow specic path.
