Interesting. Could you elaborate on how it works.

Why did you opt to place your omni-wheels in the center as opposed to the edges like in a traditional holonomic drive?

I'll see if I can get a newer photo, this one was taken a couple days ago.

The outside wheels work like a normal tank drive, and by adding the center wheel, you get side travel. I am hoping that it will allow the robot to circle-strafe, making travel around the rack easier

Because this is not a normal holonomic drive.

Last year when our team was considering omni wheels, I also thought of using this 3-wheel system. The advantage to using 2 forward/back and one side is that typically you need less power going side to side. Having only three wheels eliminates the need for a fourth motor, and saves weight.

just curious-
are your electronics going to be attached to the metal plate at the bottom, or will there be some sort of separation between the two?

the electronics are going to be mounted on a plate above the drive

Yes, but why not place them in a triangular formation every 120º like teams have done with "kiwi-drives" in the past?

Ease of programming? Also, If they wanted to have it drive like a normal Tank, and have the side to side 'strafe' controlled by a different means than regular turning... it would be much easier with this configuration.
