I really like the idea of using the omni wheels in the middle. However, there is one thing that I noticed about this base that you might want to change.

Right now, the axes of the wheels on the mecanums, from the top, appear to be making an O or a diamond shape. That means the axes are making an X if you're looking at it from the bottom. You want the X to appear from the top rather than the bottom.

You would still be able to achieve the holonomic effect with the way your wheels are set up now, but it would be extremely easy for any team to rotate your robot by pushing on a corner of it.

All you have to do is switch the wheels front to back, or left to right, and you're good to go.

If I'm not mistaken, the software should be very similar, if not the same. I haven't worked with mecanum wheels for a couple years and when I did, I didn't do any coding, so that last bit may not be correct.
