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?

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?

Redo91 · #6 07-02-2007, 17:39

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.

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.
