I think you are making this harder than it has to be.

What language are you using?

In LabVIEW, you don't have to use the polar form to use the gyro. You can use the gyro with the Cartesian form too. See attachment.

I know, we used cartesian last year but we had to keep zeroing the gyro

I want to use polar so we don't have to deal with the gyro

What I hear you saying is this:

1) last year, you had a mecanum drive

2) you used the LabVIEW holonomic Cartesian vi

3) you used a 3-axis joystick

4) you connected (Y, X, Z, and gyro) to (Y, X, rotate, and gyro) on the Cartesion vi

5) the gyro kept losing calibration

6) you think that switching to the polar form of the vi will solve your problem.


Is the above accurate?

[captainking]

yes

I don't understand what you mean. Do you want to use a gyro and "just have it work", or do you not want to use a gyro at all? There's no connection I can think of between using a gyro and the choice of polar vs. cartesian mecanum drive control.

If you don't want to use the gyro at all, you can wire (LabVIEW) a zero constant to gyro on the holonomic VI. It will then drive normally without any respect to the gyro/field orientation, just like simple tank/arcade/etc. drive. I found this by looking at the help page for that VI.
