Simple 2-Speed 6WD for teams with few manufacturing resources

2. The wider wheel actually makes it possible to use COTS spacers for the axles. A narrower wheel would require spacers that are longer than are available from McMaster-Carr. It's trivial to buy longer stock and cut it down, but I like shopping, not machining

I wouldn't say that it's better than 1114's KoS. I've seen only their brief video about the KoS assembly, so I am not even entirely sure of what their recommendation requires. This was just my stab at the idea of an enhance Kitbot.

There are few things about it that are clearly different; it uses a shifting transmission instead of those included in the kit, it uses 4" wheels rather than 6" wheels and the transmission mount and tensioner design suck

I THINK we may end up using this this year, that is is 1114 doesn't release their KoS soon! (Karthik, that's your cue!)

IMO, just get correctly sized chain and the tensioners won't be needed. Once again, great job! Now let's try and see how you can make this better, since improvement is always fun!

EDIT: Madison, is there any way possible to make the attached file Mac-friendly? I can't seem to open it, and now that I've downloaded it's like waiting for a game hint 4 days before kickoff!
