Many great attachment methods need more than the remaining 1/4" inside the plywood after using 3/4" plywood, thereby seemingly exceeding this 1" hard parts limit.
What am I missing here?
Is there not actually any limit to how far the "hard parts" can stick inside your robot? Can someone point me to some rule or clarification that indicates this?

emphasis mine.
Seems pretty clear to me. The 1" is counted from the frame perimeter.
I guess bumper attachment system can be ridiculously huge then, but at some point the bumpers will hit the 15lb limit.
