Line Follower Obstacle Avoiding Robot Richa Chauhan

A Line Following Obstacle Avoiding Robot is a Robot which follows a distinguished colored path (black lined path) and if any obstruction is present/introduced in its path then the robot avoids its collision with the obstruction (usually by stopping before the obstruction or by changing path) using ultrasonic sensor, IR sensor and Arduino. These robots are pretty cheap and easy to design. Infrared Sensor is used to detect the black line on the path and Ultrasonic Sensor is used to detect obstructions on the path. The robot then responds to the sensor's reading and does something. This robot can follow a thick line of at least of 1 inch width perfectly and even follow the most complex path consisting of obtuse/acute angled turns and intersection of those black lines.
