I hadn't considered that it would warp, thanks for pointing that out! I'll look into it. Our sponsor wasn't sure, they are primarily a steel outfit.

I neglected to mention that we are building this drive right now, the 2x1 entered machining yesterday. Unfortunately for swerve drives, we subscribe to the "swerve is never necessary" ethos. Even though I think your drives are pretty brilliant.

I'm assuming you are choosing to use a custom transmission because it fits your resources better than a COTS one, though if it doesn't I could always lead you to some sources about why COTS transmissions are a great solution.

All that aside it looks like a very promising design that will serve you well should you choose to use it for the 2015 season.

The strand thickness was fairly arbitrary, we weren't sure how thin we could go and still have torsional strength, looks like we can scale it down a fair bit (though not to your level....yet)


I'd prefer a COTS gearbox over this one, but we use the gearboxes to teach advanced CNC code to students. All of the CNC code used to mill these gearboxes is handwritten. The only other advantage to this gearbox for us is it sits much lower than a WCP or Vex gearbox in the frame. Personally, I'd like a 2-stage gearbox (16.8 FPS is high) w/ shifters, but team history precludes that effort for the time being.

It simplifies our drivebase, with belts we would need tensioning blocks and would also run the small risk of snapping a belt. We ran our drivebase without chain tensioners last year, and that's carrying over because it worked so well (71 matches, still within tolerance).
