We had a mecanum drive last year with great success. Balance is the key. Our drive only drifted a little and we had no encoders. We are using the same drive system this year with encoders. The mecanum wheels we purchased last year from AndyMark required a lot of work to assemble and modify. We did not find AndyMark wheels to be precisie enough, holes didn't line up, rollers were not perpendicular to their mounting plate sections. Where else, besides AndyMark, can we get 8" mecanum wheels?
