Make a line follower robot without writing code and without making complex circuit connections :)

EasyLFR is the fastest, easiest and most convenient way to build a line follower robot. Even with zero experience, you can built a line follower in the shortest possible time using it, without writing a single line of code.


We know how hard it is to build your first line follower robot. Learning, writing and testing those tedious codes takes a huge amount of time. And those complicated circuit connections can go wrong at any time. So, just get an Easy LFR and avoid all of them. 


Programmed microcontroller, motor driver, push buttons, graphical OLED display- everything has been included in this compact controller board. There's a line sensor array too, included with it. You'll need to add a robot chassis, a battery, two motors with wheels & a ball caster along with this product to make a line follower robot.

Check the "Documents" section for User Manual of EasyLFR.

Q: How to reprogramme this. Questioned by ShaanNabid, 02-Sep-2017

The product is not meant to be reprogrammed. As we are not providing any circuit diagram of the product, reprogramming will be meaningless anyway. Answered by A.R, 07-Sep-2017 10:49 AM

Q: Can this detect sharp turns and line gaps? Questioned by Anindya11, 07-Sep-2017

can detect sharp turn, not line gap. Answered by A.R, 09-Sep-2017 09:55 AM

We have added line gap and '+'intersection detection in the january 2019 firmware update. Now robot will go STRAIGHT over line gap and '+' intersection. Answered by techshopbd, 04-Apr-2019 16:07 PM
