I'm gonna have to disagree with you on one point here. If you use field-oriented driving controls, it probably makes it easier to learn to drive the bot, since it will always move in the direction the joystick is pointed. Combined with a spin control the driver is comfortable with, you've got an intuitively controlled omnidirectional drivetrain, and its driver doesn't need to think about which way it's facing to move somewhere.
