Line Follower Robot in 8 hours max(Scratch Build including C++ ,+ code)
We will create a line following robot around the QTR8D from scratch, no plans, no ideas! Just improvise the whole build -- this is great practice.
We make the chassis from cheap Styrene, all the components (H-Bridge), Pi 3 motors and wheels I had laying around. The QTR8D was the only thing I specially ordered for this project.
I really wanted to make the QTR8 and Motor libraries myself, for this device to test my own algorithm idea, so I refrained from using pre-build motor and qtr8 libraries. Only pigpio library was used to avoid low-level GPIO calls (we done that I the last assembler video ;) )
