YDDR: 10 lb drive base

As functions approach asymptotes they may produce results that are mathematically sound, yet physically meaningless.

Each gearbox is roughly 1.05 lbs, friction driven directly off a NEO for a free speed of roughly 10.25 ft/s.

Ummmm for varying definitions of gearbox, sure.

I do see a whole lot of non-structural metal in those side pieces, maybe consider taking a holesaw to them?

Never, just wrap another rubber band around the NEO shaft every few matches :smiley:

Can you even call it a gearbox when there are no gears?

Finally a CD drivetrain that’s truly innovative.

Fill those keyways up with epoxy

If you switched to Falcons with spline shafts, and spring mounted the motor to maintain normal force between the shaft and wheel, this could be quite effective.

This wouldn’t be the first FRC drivetrain with friction drive

The Mighty Mouse!

You got some balls to say that…

[Sorry… I just could NOT resist that one.]

I don’t know what you’re talking about, this work of art has been around for almost 10 years:

I’m really tired of all those ridiculous designs people have posted. Thank you for sharing your innovative and highly competitive design (watch out guys guarantee 254 and 1678 are switching to this drive train next year)
