I was able to find documents by first going to this page
http://archive.usfirst.org/roboticsp...control-system
and then clicking on the dead link, copying the name of the document from the dead link, googling for that, and finding another archived copy. For example
http://www.education.rec.ri.cmu.edu/...ation-0-5c.pdf
Might work for several of the documents?
