I'm starting to develop some sketches of a crab drive for a future robot and I've been putting quite a bit of thought into the joystick configuration.

What's the most common setup you've seen? I've thought about a single joystick for translational control with a left/right joystick for rotational control.

What else have you seen at the competitions? I admit to not having paid much attention to what the experienced crab teams like Stangs do, so I'm hoping to get some ideas of how it's handled.

Suggestions on our team have ranged from a single joystick plus a dial control for orientation to twin joysticks that act in a way soas to mimic skid steering (to a degree).

So let's hear it - what's your control scheme?
