Great timing Ken - you are correct as usual about this issue. This is what I hope for a spare parts rule;
Spare parts are clearly defined as any part that is used to replace an existing part. The part does not need to be an identical part made from the same materials, but does need to function with the same intent as the parts that they replaced. This allows improvements in durability, but not in functionality. These do not need to be completed and shipped with the robot. They may be created during the competition days (Thursday thru Saturday) and they may be created in advance and brought to the competition.
Additional parts are clearly defined as parts that add functionality. As long as they meet all of the other requirements for inspection, weight and size, they can be created and added during the competition days (Thursday thru Saturday) only.

Just my 2 cents worth on this - in advance
