I believe he did, in the original post. It's implicit, but the x and y directions definitely imply two wheels:

We're going to try adding small, non-driven wheels in the center of the robot, perpendicular to each other. Each one will be on a pneumatic powered arm and be connected to an encoder so we can measure how far the robot has traveled in the x and y directions.
