using 6 sensor to track the line and 2 H-bridge to drive motor
You can make a simple robot .You can align 6 sensor to follow the line .
It is not very diffcult I've just finished it.

if you have finished it, send us some pics of it. and schem etc (email it to me if oyu dont want to make it so public. i'm just interested. dont worry, i wont build this my own as a school project or something else... i have my own bots.

thanks

may advice in 2 words:

1-use a microcontroller, it may be a litle tought in the begining, but once you get used to it, it will make things sooo much easier..

2-use a motor driver chip like the L293D. will save you lot of trouble.


if you want to build an orriginal line detector yourself, here is a simple, undertandable principle on working with IR here:
