These calculations result in the reduction of total overall maximum speed (not using the full range when traveling in the forward/reverse direction) in favor of overall normalization of speed and yaw rate. "Beast Mode" basically allows the driver to override this control decision. |
As Ether noted this year the math in the provided holonomic drive VI's corrects for this already and no optimizations are required to achieve optimal drive output, though this was an issue last year.

This is something that we had trouble with the first time we used holonomic wheels also. Be careful that viewed from below your robot the rollers on your wheels form an O and not an X.

When it comes to the competition: to the engineering design challenge, we're NOT all winners -- some solutions are better than others. - JVN [more]
