Dan,
Thanks for the publicity shots. The white castor wheels are used to keep the tracks off the floor in high-speed. If we need power and traction, the castors are raised and the tracks are engaged. Note the pot just above the rear wheel that gives feedback on castor position. We are driving the tracks with the Fisher-Price drives and the front wheels with drill motors. In years past we had shifted the transmissions on the drill motors to get two gears, but were never very happy with the reliability of that arrangement. We went with the "half-track" system in part because we couldn't fit full tracks within the twelve feet of belting that is allowed.
Greg
