Claim 11:
12. A surgical method comprising:
positioning a navigation array attached to a coupling system of a distal end portion of a surgical robot arm in an orientation of a plurality of different orientations defined by the coupling system;
determining a location of the coupling system of the surgical robot arm using one or more encoders of the surgical robot arm; and
determining a precise location of the distal end portion of the surgical robot arm using a navigation system by:
measuring a precise location of the navigation array by visually observing the navigation array,
receiving the location of the coupling system via the one or more encoders,
determining the orientation of the navigation array based on the visual observation and the received location of the coupling system, the orientation of the navigation array defining a precise location of the coupling system based on the determined precise location of the navigation array, and
determining the precise location of the distal end portion of the surgical robot arm based on a known spatial relationship between the distal end portion and the coupling system.
