at least one camera able to detect the plurality of fixed tracking markers and the moveable tracking marker on the instrument, wherein the robot determines a position or movement of the moveable tracking marker to determine a level of expansion of the implant,
wherein the implant is an expandable interbody fusion device positioned between adjacent vertebral bodies,
and wherein the surgical robot system correlates the position of the moveable tracking marker to a particular position, orientation, and height of the expandable interbody fusion device and determines the height of the expandable interbody fusion device based on the location of the moveable tracking marker.
