We are attempting octocanum this year. We have working field centric & shifting control.

As of late, with our practice robot,
We have broken three VEXpro mecanum 4" rollers and
here are a couple questions we are facing at the moment.

How to reduce stress on the mecanum rollers ?
a. proper amount of frame flexiblity ?
b. slop in the axles (using churro vs VEXpro black hex)
c. limiting power of wheels during strafing to avoid stress on rollers
