Basically, yes. The omni-wheels are mounted at 120° angles ot the center of the robot. BTW, if you would like to see a video of one of these in action, here is a video of a kiwi drive robot from Team 857 in 2002.

Re: The Annual Drives Platform Poll

So what's up with 10WD+?

I think we'll end up with 12 wheels, but only 6 will be powered.

No swerve drive yet? I thought that would be a popular solution this year...

Re: The Annual Drives Platform Poll

Someone please describe the difference between Crab and Swerve. And while you're at it, tell us what omni means. I'm lost. I thought Omni, crab, and swerve meant essentially the same thing.

Crab and Swerve are the same thing, Both have "modules" which turn in relation to another. As omni's do not require the drive to move, just the wheel..

Crab/Swerve:

Re: The Annual Drives Platform Poll

We are using the Crab Drive meathod on our robot. Also I was wondering the efficiency of the Kiwi Drive system. See the video I believe it would be easy to trap or "Pin" this robot on the sides not even needing a corner. Could someone that is using it explain maybe?
