what exactly is nona-drive? I've heard a lot about it

Nona-drive is a 9 wheeled robot 5 omni wheels 4 "treaded" wheels. There is an omni wheel in the center of the robot that runs perpendicular with the rest of the wheels, then at each of the corners there is a "pivoting system" that lifts the treaded wheels off the ground so the omni wheel in the center of the robot will then be able to drive the robot on its axis.

Thats my basic shake down about the concept.

Any idea where we could find some pics or something? I'm intrigued!
Tried some google searches, couldn't find anything though...

This was the drive system that 148 and 217 developed and implemented this year.

You should check out this thread.

JVN also included some CAD renders of their (148's) robot in the build diary he made this year.

in the off season we experiment with different drive train and other ways to improve our robot for the off-season events so let me know what you think

Very well implemented, though I'd consider game-by-game whether you really need supershifters. Something lighter, depending on your ratio. We've put shifters on robots with omnis, but not often (or at least not wisely) and only after considering our exact strategy. You won't be pushing.

I'd also think hard about exactly how you--or rather, your drivers--want to control it. Consider it, design it, code, test it, and then test it again. And again... I've seen teams (ours included), regardless of programmer skill, have serious problems in this area with such agile drivetrains. Leave time for driver practice!

While your point is still completely valid, I'd just like to add that one of the benefits of a slide drive is how easy it is to control with the most rudimentary of code. If I didn't know better, I'd make one myself! o.0

it was easy to control anyone who know how to play first person shooter games like halo or call of duty could drive it. the drive run off the same controls on an xbox 360 controller left joystick is forward, back, right, and left and the right joystick is spin left or right
