Re: Problems with Vex Pro mecanum wheels

In logomotion, we also used machanuum wheels, and they strafed much better. An issue we are occuring is our gyro drifting this year too though.

Also, your robot being 28"x28" doesn't necessarily mean your wheelbase is a square (but it may very well be or "close enough").

Mecanum does not require that wheelbase and trackwidth be equal.

This is the first year ours was even close, and from what we could tell it made no difference whatsoever from a driver standpoint.

A drop of oil on each roller's axle can help a lot.

Also, during use the rollers can develop sharp edges on either side and sanding those down will keep the rollers from digging into the carpet when strafing.

FYI: I speak from experience with AM mecs, not vexpro.
