You can't, the only place that sells mecanums for FIRST robots is andymark. There are other companies that use mecanums but for the most part they simply use them in their own vehicles and don't sell the wheel separate. In addition these compainies make things like forlifts and you aren't going to find a small enough wheel.
For the actuall control I would strongly suggest using a gyro instead of encoders, the code is easier and it isn't suseptible to slipping. I have done a holonomic for the past 3 years and last year ours was a rock, it didn't drift, it went in a perfectly straight line and overall just ran extremely well and we didn't use encoders, just a gyro.
I know I exaggerated a bit, but NASA put a man on the moon with less processing than some FRC bots. Think about that for a minute. - JesseK [more]
