C would be at -, A towards -. D towards+.
right? with B still at neutral. so then the robot would be doing the same thing.
rotating counterclockwise with B at the axis.
so now comes the place where a little more imagination is req'd.
now move the stick the same way as before(b as the axis counterclockwise) but now move the axis of rotation a little closer to the A stick. so A-,C-,D+ but B is only slightly towards +.
guess what? the robot does the same thing. the axis it is rotating at is a little above B but a littel towards A too. and it is shuffling towards NE too. i think. i confused myself slightly. forgive me. its a friday night. but i just wanted to prove you COULD translate and rotate at the same time. NO problem. just a matter of driver getting used to.

Build it and prove me wrong. I'm certain that you will not be able to drive along a straight line while rotating at the same time. You may be able to approximate it but it would take a driver savant to keep track of the orientation and keep the translation along the same vector.
