If there are two of these, you could do that between the sides fairly easily.


But I can't think of many cases where a swerve would need to pivot around a specific point (that is, center of rotation) that isn't the center of the robot. Depending, of course, on the swerve, and what's on top of it. There have been some very good swerve drives that could not pivot at all. (They had other means of getting aligned with targets and all that--or not, as the case may be.)

we have used a off center pivot on our code before, (it would rotate around the two front corners dependent on which button is pushed) witch was insanely useful to pivot the robot around other robots, you could also use an off center pivot to "lock" the distance on to whatever goal the game has. off center pivot's has some uses, but not needed, just helpfull.
