Did you check the book : Robot Builder's Bonaza, Fourth edition, by Gordon McComb. http://www.mhprofessional.com/sites/RBB4/
I bought the book and I also have the first edition back in the 1990's.
So let see... your are learning electronics ? That is great. Build in steps, Learn in steps.
What about your programming skills ? You need that for the programming. Beging with small things first.
And what about your mechanical / construction skills ? You need that for the building and figure out the mechanical aspect of it.
Good luck. A long learning road ahead...
