We are using Holonomic Mecanum drive this year and it functions fine without using a PID loop to adjust the wheel speeds (although we did that last year for traction-control ).

Good Luck!
Hi lscime,

Thanks for sharing your experience with mecanum without closed-loop control of drive wheels. I think that's what we are going to settle for this year because giving our brand-new software guys another task would be too much at this point I think.
