LFR <-- Olin's TCP/IP Network Stack You'll need to tell us what you know and what you need to know, and what you've done and what you need to do. Nobody here is going to do your project for you (probably :-) ) but you can expect lots of useful input IF you are willing to explain everything well and in adequate detail AND if you listen to what yuou are told and don't ignore good advice and keep trying to do things which are unproductive (That's not based on what you've said so far - MOST people who come here needing a lot of help tend to not tell us enough and not listen to advice given and don't try suggested ideas before asking the same question again. You can do better than the average person by doing it right from the start)= .. All that said, Google has lots and lots and lots of advice on line followin= g robots. Many many people build then because they are relatively easy to do and fun when they work. Here are just a few of ther many pages that Google knows about: PIC Excellent http://linefollower-robot.blogspot.com/ Excellent tutorial.
