Line Follower robot is a machine that follows a line, either a black line on white surface or vice-versa. Nowadays, every robot is done with the help of the microcontroller, and hence the circuit is too big and tough to understand and makes it costly. For these reasons, in this project we have developed an intelligent Line follower robot with a simple concept with simple circuitry. Basically, there are two types of line follower robots: one is black line follower which follows black line and second is white line follower which follows white line. Here we have designed the first one. Line follower actually senses the line and run over it.
A micro controller is an integrated circuit that is capable of running programs. There are many instances of those on the market today from a variety of manufacturers. The prices of these micro controllers keeps falling. In the hobbyist market, an open source architecture called "Arduino" that uses the Atmel range of processors has caught the imagination of countless folks. The boards containing these Atmel chips combined with a convention for connections and also a free set of development tools has lowered the entry point for playing with electronics to virtually nill. Unlike a PC, these processors are extremely low end with low amounts of ram and storage capabilities. They won't be replacing the desktop or laptop any time soon. For those who want more "oomph" in their processors, the folks over at Raspberry PI have developed a very cheap (~$45) board that is based on the ARM processors that has much more memory and uses micro SD for persistent data storage. These devices run a variant of the Linux operating system. I'm not going to talk further about the Raspberry PI as it is in the class of "computer" as opposed to microprocessor.
