Abstract
A surgical system and method involve a robotic system with a base and a localizer that monitors a tracker supported by the robotic system. Sensor(s) are coupled to the robotic system and/or the localizer. Controller(s) determine a relationship between the base and the localizer. The controller(s) monitor the relationship to detect an error related to one or both of the robotic system and the localizer. The controller(s) utilize the sensor(s) to determine a cause of the error.
Claims21
A surgical system comprising:
- a robotic system comprising a base;
- a localizer configured to monitor a tracker supported by the robotic system;
- one or more sensors coupled to one or both of the robotic system and the localizer;
- and
- one or more controllers coupled to the robotic system, the localizer, and the one or more sensors, wherein the one or more controllers are configured to:
- determine a relationship between the base and the localizer;
- monitor the relationship to detect an error related to one or both of the robotic system and the localizer;
- and
- utilize the one or more sensors to determine a cause of the error.
A method of operating a surgical system, the surgical system comprising a robotic system including a base, a localizer configured to monitor a tracker supported by the robotic system, one or more sensors coupled to one or both of the robotic system and the localizer, and one or more controllers coupled to the robotic system, the localizer, and the one or more sensors, the method comprising the one or more controllers:
- determining a relationship between the base and the localizer;
