The question I had was "How are you getting the Colson wheels to move in an arc using cylinders that are pushing in a straight line?" The answer made sense but was simpler than I expected.

The cylinders are perpendicular to the centerline between the two mecanum wheels. The bracket which moves the Colson wheels swings on an arc which is centered above and below the mecanum centerline. The cylinder is positioned at the midpoint of this arc to minimize the error and then the bracket holes are oversized slightly to accomodate the error.
