The 2005-2006 kit drivetrain was a sheetmetal frame designed by a college student (John V-Neun, you might've heard of him) with a single-speed gearbox designed by Paul Copioli (you might've heard of him too). This was the first time you could order all the parts online in a non-obnoxious manner, through IFI Robotics. (The internal spur gears were sourced from an upstart company in Indiana called AndyMark.) The molded hubs on this drive system that clamped around the kit Skyway wheels (remember those?) established the 1.875" bolt circle as a de facto standard for FRC that remains today. (The cast housing and metric-sized output shaft on the gearbox? Not so much.) I don't remember when the original AM Toughbox came out, but I know we were evaluating it during the 2006 season. It became part of the Kit of Parts in 2009 and 2010.

But yes, the original AM Shifter does trace its lineage back to designs introduced by the TechnoKats. Many of the shifting parts have carried over to successive designs, even as things like external output shafts, servo shifting, room for more motors, and encoders have been added.

Yeah I should have clarified that I was mainly speaking of the AM shifter... as I among many others know the former technokat that designed it as a student on 45.

The tough box came out in 2008 KOP. 2007 had the same setup as 2006. I thought they were AM gearboxes because of common gears... I was obviously wrong.

2007 did not have the same gearbox as any other year. That was the year of the BaneBots 56mm gearbox, which in as-shipped-in-the-kit form was not remotely ready for the task of playing a very physical game like Rack 'N Roll. (Whether they were ready after the fixes that went out was a rather subjective matter that depended on your application.)

You are correct that the Toughbox first entered the kit in 2008. We used SuperShifters that year on 1618, so those sat off to the side.

That's interesting. On 1747 as a freshman in 2008 I remember finding 4 old KOP gearboxes cases made of cast metal; their rookie year was 2006 and they at that point had never used stock gearboxes (AM Shifter Gen2's in 2006 and 2007). Thus it made sense for 2 to be 2006 and 2 to be 2007. I hadn't even heard of Banebots doing KOP gearboxes although given the era I could see them being awful (chipped gear city)... My guess is two of the castings must have been 2005 ones that were "gifted" by 461 when the team was founded.

Sorry for the misinformation.
