Abstract
Surgical systems and methods are disclosed, including, in one embodiment, a system having a coupling system disposed on a distal end portion of a surgical robot arm that secures a navigation array to the robot arm in a plurality of different orientations. The system further includes a navigation system configured to determine a precise location of the distal end portion by measuring a precise location of the navigation array by visually observing the navigation array, receiving a location of the coupling system via one or more encoders in the robot arm, determining the orientation of the navigation array relative to the robot arm based on the visual observation of the navigation array and the received location of the coupling system, 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.
