Omni-wheels and driver-centric drive

For angle a gyro would be most accurate. For more consistent drive encoders would be nice, but are not necessary for the effect that is desired.

However, a gyro to keep a constant front and encoders to maintain even speeds would result in a very nice and friendly base to the driver.

EDIT: Hmm... I didn't see where you said nonpowered... I'm not sure how well that works for angles, I bet it works well for distance/ location but I doubt it would give more precise angle readings than a gyro.
