Re: Omni Wheels Survey

Wildstang has used a variety of different designs for omni wheels over the years. We scratch build our own and have modified the design each time we used them. This year we used two driven omni (we call them BUPODfor Biased UniPlanar Omni Directional) and two crab drive modules for four wheel drive. In crab from side to side we had to add some software to help the robot drive straight which we called "Drive Straight". The omni wheels tend to go where they want when they are not driving.
