Line Follower with Obstacle Avoiding Robot

An intelligent robot called a "line follower" finds and follows a visible line that is embedded in the floor. The predetermined route can be seen as a black line on a white background with sharply contrasted colours. It can recognize the existence of an obstruction and select a different route to its destination. The robot that detects a line and tries to move in the direction of the target can be programmed to follow instructions. Different sensors can be used to detect the line. The robot can identify the path it needs to take using infrared sensors. The ultrasonic sensor is a device that can detect the obstacle by measuring the distance using sound waves and avoiding collision.
