Fuzzy logic control for a line following robot


Hi i need to do the programming with a QTR-8RC Reflectance Sensor Array. Can someone help me?

I'm sure there are many people who can help you. If you post a more specific question, you will probably get a more specific answer ;-)

I am constructing a line follower. I am having problem to program it using fuzzy logic.
The robot has QTR-8RC Reflectance Sensor Array as a sensor to detect the line which consists of 8 phototransistors .
It is using differential drive steering meaning that it will have independently powered  2 DC motors.
The speed of both motor vary using PWM to perform turns and straight line driving.
The idea to use fuzzy logic is keep the line on the centre of the robot that is at the fourth and fifth phototransistor. If it is to the left of the centre, the left motor will run faster and if to the right the right will run faster.
It is using l293D motor driver and a 16F877A microcontroller.

Please help me, i am doing it for my final year project BENG Mechatronics.
