I'm not trying to denigrate what 192 did last year, because they made a gorgeous, highly functional gearbox, but it should also be asked "what advantage does 192's gearbox design hold over a COTS or modified COTS solution?"

Moving the motors out of the way isn't a good enough reason for most teams, IMO. What is all that extra work and potential compromise of reliability really buying you? An extra 8" in the interior of your robot that you probably don't really need anyways?

192 had the benefit of doing something similar (with worm gears) to OP's design in 2012. They didn't do it again after that. They have at least 4 revs of their 2014 gearbox (as I recall they made 2 prototypes in the 2012 offseason, plus the 2013 gearbox, then the 2014 gearbox).

There are so many better obstacles for most teams to tackle than making custom gearboxes. If 254 were starting a new team right now, I highly doubt we would make custom gearboxes. Maybe custom sideplates to get the right ratio, but that's about it. The stuff that's out there now is so high quality that if you have any question about your ability to solve every other aspect of the game challenge, you really shouldn't be going custom.
