I had never actually built a line-following robot until now for reasons unknown but I have to say the experience was enlightening. Getting a refresher in some analog circuit design did not hurt either.
Below is a test run of how well the line-following mini-tank works. It is suprising at how simplicity can meet functionality dead on!
Purpose & Overview of this project
The purpose of this project is to build a device that can sense the difference between black and white color so that the robot can follow a black line on a sheet of white paper.
The robot will be low cost and completely made in a DIY style. It will also be able to follow straight and curvy lines alike.
