The fastest and easiest way to build your first line follower robot.

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. All you need to add is a robot chassis, a battery, two motors with wheels & a ball caster.

How to reprogramme this.
A.R | Sep 7,2017 at 10:49 AM
The product is not meant to be reprogrammed. As we are not providing any circuit diagram of the product, reprogramming will be meaningless anyway.
Anindya11 | Sep 7,2017 at 07:06 PM
Can this detect sharp turns and line gaps?
A.R | Sep 9,2017 at 09:55 AM
can detect sharp turn, not line gap.
Techshopbd | Apr 4,2019 at 04:07 PM
We have added line gap and '+'intersection detection in the january 2019 firmware update. Now robot will go STRAIGHT over line gap and '+' intersection.
