Neat!

It looks like with a drum on each second stage gear, that you would need air pressure to engage either gear set, regardless if it is low or high gear, is that correct? Seems like a big plus to that is you can shut off your air pressure after a match and the robot would roll freely with no motors engaged.

Based on the results of this off season project, do you see enough benefits to use this approach (instead of dog shifting) if the game requires a two speed drivetrain this year?
