4 Oct Here is a simple line following robot circuit designed using ATmega8 Microcontroller. It can be used in industrial and defense applications. You can try declaring sensor as volatile: volatile uint8_t sensor;. 4 Aug Hi all, I am new here and about to make a debut in robotics with a simple line follower robot. I have chose AVR ATmega8 as my microcontroller.

By Ashish Inamdar – November 29, 5: Its connected to the power supply and ground. But since PIND rlbot already defined as volatile “under the hood”, isn’t that sufficient for the compiler to suppress assumptions regarding the value of PIND and thus not optimize the assignment to sensor? This type of robot is run over a white surface which has an arbitrary path drawn over it by using back paint.

Or if you come to us for anyother folllower that may arise in your path? That makes uploading easy when you have to do it a lot. Avinash, I happened to see this tutorial. Similarly if control variable is less than 0 that means line is towards the right, so we need to take left turn to correct the error and bring the robot back to track.

I want the bot to take a reverse turn when the black line ends and follow the same line again. By venkatesh kosuri – December 22, And if any problems i will try my best to solve it on my own. You ll want to use atmega pins 2 and 3 for communication and not motor control because they re hardware serial.


By Dibyaranjan – July 6, 8: And how the bot behaves when we get a sharp 90 deg turn like sharp left turn in which sensor 1,2 and 3 are on line. For more information turning the robot please see differential drive mechanism.

But the problem is that our competitors are using a rpm motor…So we wanted to know that if you are having the same kit everything same but supporting a rpm usung its available with you please contact asap….

Line Follower using Atmega8 – General Discussions – RobotShop Community

Sir, would you please provide me the library files. Navigation Home Store Links. By Jalaj – February 8, 2: Switch on the robot and see the action.

The task of the robot is to run exactly along this painted path. By Jalaj – February 6, Leave a comment in a proper manner with sufficient details so that we can help you.


Place the robot over the line. Dear sir, i always follows your post and tutorials and like very much. By Rajesh Rajan – January 4, By raman – March 16, I planned on robit and then delaying the motor for 3 second and the switching them off but the robot has started to work haphazardly.

What should I do? By Avinash – April 21, Dear sir, I am looking for your address.

Line Following Robot using AVR ATmega8

Thank you for he elaborate instructions. The things which I need to know is: I am trying to build a Line follower robot using atmega8 which can park itself when both the infrared sensors detect black. How to handle such suitation. Otherwise I will have to purchase atmega 8. If you want to folkower for ATmega16 you have to change the connection and also the program. Take a 1 minute test. High Quality Metal Chassis. You can save lots of time and pay more attention in the program part that is more important.

By ashish – November 9, 8: Also put a 0.
