R22 and previous year's designs

[Bob Steele]

You are allowed to take ideas and designs that you have developed and rework them and use them
You just can't take a previous design and use it exactly like it was developed before kickoff.

You cannot EVER use a fabricated part from another robot. Even if you alter it.
It is only an altered design that you can use. You may reuse COTS parts if you have not altered them.

This, I believe, is what this states...
