A PID controlled Fast Line following Robot

This is a basic Line follower based on PID Algorithm. The robot base is home made PCB. The robot is running at 1.2 m/Sec. The PID configuration is still in progress. I believe with a good PID value it can go up to 1.5 m/sec. Robot consists of two 6 volts motors running at 9 volts through adjustable voltage regulator.

I made the robot round shaped as it will perform two functions

1. Line following

2. Line maze solving

Maze solving code is still in progress.

Parts Used are

Microcontroller - Atmega328 PU running at 20MHz

Motor Driver-TB6612FNG

Sensor-Pololu QTR 8A

 

The Pololu QTR 8A has 8 IR sensors of which 6 are used as Atmega328 PU DIP package has only 6 ADC channels.
