I have found some small tutorial about creating line following robot.I think,it is a small practical for beginners like me.

if you wish to start learning about PIC or Robotics,i think this may important to you.But,this is not a complete,step by step tutorial.it is not big problem to beginners.
Get a inductive start for your tour.

As i know,this tutorial provide by Vidyaloka College of Galle as their A/L group project.

This tutorial has three .pdf file which included details about robot
LECTURE 1.pdf has some basic information about technique of robot,electronic components that will use,....
LECTURE 2.pdf has PIC Micro controller Programing using MikroC.(PWM,Coding....)
LECTURE 3.pdf introducing tools which are use.
