This is my very first line following robot that is built around ATMEGA8. Construction and circuit are quite simple. Such a name- GOOFY is given because robot movements are somewhat clumsy. But hey! Its still working and doing his job very well! :)

There is two geared DC motors that are controlled using PWM. Tyres are the ones that are used in RC cars. Besides-these have a nifty looking. 

You may ask "Whats that tho pieces of metall on screws in front of robot? ". The thing is that batteries behind robot is a bit weighty so it lift the front with sensors (which means that sensors can not sense the line :( ). As a solution I added two screws and some parts from an old equipment in front of a base plate. Hahaaa- it works! :D 


Everything started with this: 

Here is a circuit if You're interested: 

Hope You like it! :)

That's a very cool robot!  I really like the acrylic base.  Did you make that yourself?



Yes. I cut the base with handsaw. A bit of work -and here it is! 


Nice Wheels mate, where did you get them from?
Thanks! :) These are RC Car model wheels. I get them from a local shop.
Oh :( They are really cool :) Hmm got to finde something like that ;)

The circuit diagram is not visible..please make it visible

plzz send me the circuit diagram on my mail as soon as possible, I am eager to make it my mail id is nileshhaldipur@gmail.com

thanks for ur help but the file has got an extension  .lay i just want to know which software supports it....

good job!
