Richard, our robot can drive any direction it wants to, and at the same time rotate. Much like the videos Madison posted.

If the point of rotation happens to be translating as you rotate, you are pulling off a very tricky move--that sort of motion is usually reserved for things like frisbees, not stuff that stays on the ground.
The point of rotation is not a point we directly control, it is determined by the combination of x, y and rotation inputs. It is only ever on the robot when our translation speed is very slow or nonexistant (which I guess is true of all FRC robots).
