Re: pic: OMNI Drive

Team 341 did a variation of this in 2007 and 2008.
However, we placed the wheels at the corners.
Our nickname for this configuration was "Z-drive".

If you do this, you have to be resigned to the fact that everyone can push you around at will.

We were OK playing a "run and gun" game in 2007. It allowed us to always face the goal with the tubes and just drive sideways. Then in 2008 you were not allowed to contact each other, so we did not have to worry about defenders.

We won the Philly Regional with this drive configuration in those two years.
That being said, it has a limited range of uses for most games.

Ether answered in the previous post. √2 - 1 =~ 40%.

And thanks for keeping us honest, Ether!

Re: pic: OMNI Drive

If you haven't built a holonomic drivetrain before, don't design one in the middle of build season. Just use a tank drive. If you're really set on it, then i would suggest mecanums, which can be added to a standard chassis fairly easily, or, if you really want the omnis, put them in the corners diagonally.
