Our line follower robot is the machine that is capable of detecting and following a line drawn on the floor and take necessary decision facing obstacles in its pathway. Generally, the path is predefined and which is visible like a black line on a white surface with a high contrasted color. Our robot senses the line with its infrared ray (IR) sensors that installed under the robot. After that, the data is transmitted to the processor by specific transition buses. Hence, the processor is going to decide the proper commands and then it sends them back to the driver and thus the path will be followed by the line follower robot. Our robot has three ultrasonic sensors connected with

the Arduino Uno which firstly measures the distance of obstacles and takes decisions for our line follower, whether to change its path following direction or not and all the conditions are been justified by doing  Arduino coding. The sensors and overall circuitry components are established with the Arduino Unoand these are connected through motor driver IC on a strong board chasis and powered by a rechargeable lithium battery. So, our robot is capable of passing messages, medication, and other necessary things from one place to another place.
