This video shows the rear view of the planisphere using the nearly frictionless bearings used throughout the Astro-skeleton project. Since the machine has over 500 wheels, friction is our constant enemy. Only though the use of ceramic, oil free bearings can we accomplish the drive of this machine with a reasonably sized motor spring.
