Hi,

I am starting in robotics, I already build a little robot with wheels that just goes forward, backwards and turn. I want to create more, but first I want to learn about it. Like what are the basic I need parts I need and what does it do. I know that there is a lot of information online, but I just don't know wich is the best that is free, can you guys help me? I have a good base in electrionics, I am a second year student in electrical engineering.

Thanks
