So at Team Pronto we just finished fabricating some awesome mechanum wheels. After a week and a half of hard work, we finished attaching the rollers on today. The four wheels are made out of aluminum sheet for the outside plates, ply wood for the middle hub, and delrin plastic milled on lathes for the rollers.
Lots of fun, lots of hassle, lots of time, but in the end well worth it.
Good luck from team 3070!
