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.)
