Essentially 33 ran this drive this year.

Quite a few teams have run "butterfly" drives that have this + drop down tractions as a second mode.

We found that the robot tracks straight as on carpet the omnis still have appreciable lateral rolling resistance.

Our driver quickly figured out how to drift with it, and how to control those motions roughly.

In summary, it's more far more controllable than people assume.
