BEAM is a good way too.

Just google line following robot. There is even BASIC code samples for such a robot. I am new to this too but doing your own research then asking specific questions you may have about a part of the process is a lot better. No one here would ever do you the disservice of doing the work for you. Cant wait to see your line following robot once you get it done! :)

I think a kit may be a good way to start building robots. I'm very interested in building robots and also a beginner. Several days ago, I bought the ASURO kit, according to the instruction, it can achieve the function of line_following after programmed, I'm ready to build it!!!!! English is not my native tongue, hehe

Your right, a line follower is a good way to start if your new to robots.

Although some black electrical tape on the foor is a popular choice and can be done with an IR detector or a LDR setup like Frits's. There are other ways, you could follow a laser beam or a string above the ground. You can also follow a wire under the ground which is an easy way to get your lawnmower or vacuum cleaner to follow a set pathway.

Reguardless of which line you want to follow the theory is still the same. Have a sensor either side of the line and adjust the speed of your drive motors so that the signal is the same from each sensor. If the robot drifts to one side then one sensor will get a stronger signal or the other sensor will loose the signal all together.

Well you can make one with BEAM if you really want to want to http://www.solarbotics.com/products/rbfb/ (I haven't read that book but apparently the whole book focuses on building a line following robot) Note: beam is good for beginners , but it can be a little bit fiddly and annoying trying to get a kajillion soldering joints to be perfect

Or you can make one using arduino

Or you can make one with picaxe 

Google it, and I bet you will find a ton of results

Posts that boil down to HELP ME don't typically get much help. Please create your own thread and post a specific item you need help on. Doing a little research first also goes a long way.
