Yes, LMR IS an awesome website, but some may also be interested in one I found.
See: http://www.helloapps.com/index.html All the files and tutorials for getting into MRDS.
"Microsoft Robotics Develpement Studio" (Covering both versions 3 and 4,)
This website covers all aspects of robot system modeling including mesh design and science.
(I have a book on MRDS, but trust me, this website is easy compared to the book.)
When you get a chance, check it out.
