What motors are used to turn the wheels (either 1 motor for 2 wheels, or 1 motor for 1 wheel)?

2 modules use FP, 2 use drill
1 globe motor turns the two left wheels, the other globe turns the two right wheels

and most importantly, what kind of control sytem is used (what does each joystick do)?

I don't have much knowledge about the specific mechanical details, but I can help with the controls. Ours is controlled with two joysticks. If you leave the left stick alone, the right stick is simply the IFI single stick drive system. The left stick controls the wheel angle. If you move it half way left, all 4 wheels turn at a 45 degree angle left. Move it all the way left and they turn to 90 degrees left. We expanded the crab to turn 180 degrees each direction this year by using the negative-y axis. If the left stick is in the negative-x / negative-y corner (back & to the left) the wheels turn to 135 degrees left. Continue to full back with x in the middle and the wheels turn to 180 degrees left. Same for the right side. Once you crab past a certain point, the x-axis of the right joystick is ignored and all wheels drive at the same speed.
I may have confused you (that's what I get for being brief & writing this quickly) so ask questions if you have any. Some time over the summer I want to put together a formal description of our crab control, and hopefully it will make more sense.
If you're going to IRI (and if we go too) stop by our pits and we'll let you drive it.

If possible, it be awesome to have some pictures, but whatever you can come up with I'd really appreciate. Thank you very much.

We're still uploading our build season pictures, but hopefully when we're done we'll have some good ones that will help you out. Our gallery is at
