Surgical robot platform

A surgical robot system comprising:

• a robot base having a display;
• a robot arm coupled to the robot base, wherein movement of the robot arm is electronically controlled by the robot base;
• an end-effector, coupled to the robot arm, containing one or more end-effector tracking markers;
• a plurality of dynamic reference bases (DRB) each attached to a patient fixture instrument, respectively, wherein the plurality of dynamic reference bases each have one or more tracking markers indicating a position of the respective patient fixture instrument in a navigational space;
• a registration fixture, having one or more registration markers, indicating a location of a target anatomical structure in the navigational space and one or more registration fiducials indicating a location of the target anatomical structure in an image space;
• a first camera system and a second camera system, the first and second camera systems able to detect the one or more tracking markers of the plurality of dynamic reference bases;
• wherein the surgical robot system is configured to associate the location of the target anatomical structure with each of the patient fixture instruments in the navigational space and the image space taking into account (1) a relationship between the one or more registration markers and the one or more fiducials and (2) a relationship between the registration markers and the markers of the at least two dynamic reference bases, and
• wherein position data from each one of the first and second patient fixture instruments in navigation space is continuously given an accuracy weight and the position data from the more accurate patient fixture instrument is weighed more strongly than the position data from the less accurate patient fixture instrument for tracking patient anatomy without the need to recalibrate the dynamic reference bases.
