Re: Custom Vs. COTS Transmissions

If we were to go to the effort and expense of developing and building our own transmission (a good thing), it would glorified scrap at the end of the season (bummer). If we just bought a COTS transmission and didn't modify it (normal business practice, but not as much of a learning experience), we would be free to re-use it in the future. This is a big disincentive against making anything you can buy. Perhaps FIRST could set some allowance for "legacy" fabricated parts - by weight, parts count, dollar value, etc.
If we were to invest in a pair of COTS shifting transmissions and then we drilled one new mounting hole in each (heaven forbid we deburred or lightened the gears) they would be unusable for future games. Perhaps FIRST could set some standards for minimum allowable modifications for re-use of COTS items - i.e., drilling holes, shortening motor shafts, etc.
I know that its easy to recycle a design by making some meaninglessly trivial modification, but that just encourages "gaming the system". Perhaps FIRST could allow re-use of designs that had been publicly posted.
I like the FRC supplier base that has developed in recent years, and we take advantage of it. However, when combined with existing FIRST rules, it creates some negative and unintended incentives. I hope FIRST will consider allowing limited re-use of legacy designs & hardware that teams creat or enhance with their own brains & hands.
Besides, the unique requirements for each game put a natural limit on the number and type of items that are worth re-cycling.

as of 2011, they do allow re-use of custom designs that are publicly available, as they are then considered cots
