Dave,
Much of the vibration that is transmitted is likely moving the frame for your turret so I am guessing that the camera is mounted somewhere on the turret frame. If you are using something that solidly attaches to the robot frame like a lazy susan bearing or some other low vibration mounting, getting the camera mounted as close to that point would eliminate much of the vibration in the camera. You would likely have more luck if you were to isolate the shooter from the turret as the camera does not contain enough mass to easily isolate it.
