I didn't really know which category this post would belong to, but here goes.
Me and a friend are getting interested in building toy robots, and I've been looking around the web for information. Mostly we find circuit diagrams and videos of stuff other people have done, but nothing that would help us understand the machine and roll our own.
Assuming we know nothing about electronics and stuff, can somebody give me a rough roadmap of what I should know before I'll be ready to make, say, a simple RC bot, or one of those line finder robots?
I don't want to pick up circuit diagrams and glue the pieces together. I want to understand the electronics behind the entire thing.
Are there any enthusiasts here who could help me out a bit? I don't frequent many other forums, so this is where I turned for help.
