It will be quite a bit more reading I'm afraid.
http://en.wikipedia.org/wiki/Simultaneo ... nd_mapping - the obvious starting point.
http://www.ros.org/wiki/ - describes probably the most robust out of the box collection of programs. Your robot may or may not be in the supported list.
http://openslam.org/ - has many working algorithms for 'localization', ie finding out where you are.
There are many things you need to organize; what type of programming do you already know? If none, that is the first place to start, learn to program. You must figure out what works on your robot. With 'no idea how to start' I expect it would be a 4-5 year process to accumulate all the needed skills; programming of microcomputers, math in trigonometry and probability. For me, I had a very good understanding of what was needed, and all of the prerequisite skills, and I've been at it for 2 years.
If you have the skills;
http://www.amazon.com/s/ref=nb_sb_noss_ ... slam+robot provides plenty of choices. I read, and am still re-reading
http://ocw.mit.edu/courses/aeronautics- ... s_repo.pdf - over and over until I get it. I wish I could get a degree for it when I finally do.
