    Abstract: A navigation system includes a first and second tracker supports independently affixed to a rigid object and separated by a distance. A first plurality of trackable elements are secured to the first tracker support and a second plurality of trackable elements are secured to the second tracker support. A localizer tracks the trackable elements and controller(s) define a tracking arrangement to be tracked based on a combination of the first and second plurality of trackable elements. A geometry of the tracking arrangement is registered relative to the rigid object and the controller(s) track the rigid object by detecting the registered geometry. The controller(s) identify a condition wherein at least one trackable element has been displaced relative to the registered geometry, and in response, generate an instruction to a manipulator controller to interrupt operation of a robotic manipulator.

    Abstract: A physical model configured to be physically altered by a surgical instrument for providing feedback related to a surgical plan specific to an anatomy of a patient. The physical model has a body including a physical volume representative of the anatomy of the patient and a geometrical feature embedded within the physical volume wherein the geometrical feature is visually distinct from a remainder of the physical volume and wherein the geometrical feature has parameters that are based on the surgical plan. The physical volume is configured to be at least partially removed by the surgical instrument such that the geometrical feature is configured to be exposed for providing visual feedback about an accuracy of the surgical plan and/or an accuracy of the surgical instrument in carrying out the surgical plan.

    Abstract: A navigation system is disclosed which comprises a tracker having a trackable feature, a localizer configured to track states of the trackable feature within a field of view, an illumination assembly operable to direct light within the field of view, and a controller coupled to the localizer and to the illumination assembly. The controller is configured to receive the tracked states from the localizer, to determine a status condition of the tracker based on the tracked states received from the localizer, and to control the illumination assembly to direct light at the tracker such that light reflected by the tracker from the illumination assembly is visible to a user of the navigation system to communicate the status condition of the tracker.
