Techniques For Detecting Errors Or Loss Of Accuracy In A Surgical Robotic System
Systems and methods for operating a robotic surgical system are provided. The system includes a surgical tool, a manipulator comprising links for controlling the tool, a navigation system comprising a tracker coupled to the manipulator or the tool and a localizer to monitor a state of the tracker. Controller(s) determine a raw (or lightly filtered) relationship between one or more components of the manipulator and one or more components of the navigation system by utilizing one or more of raw kinematic measurement data from the manipulator and raw navigation data from the navigation system. The controller(s) utilize the raw (or lightly filtered) relationship to determine whether an error has occurred relating to at least one of the manipulator and the navigation system.
Techniques For Detecting Errors Or Loss Of Accuracy In A Surgical Robotic System
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.
Laser-guided cutting assembly
A laser-guided cutting assembly for severing objects includes a work surface. A severing implement is operationally coupled to the work surface. The severing implement comprises at least one blade that is configured to cut an object that is positioned on the work surface. A display and a measurer are coupled to the work surface. The measurer is laser-enabled and is operationally coupled to the display. The measurer is configured to measure a first distance between the measurer and the blade, and to measure a second distance between the measurer and an end of the object that is positioned between the blade and the measurer. A portion of the object that is positioned between the blade and the measurer has a severable length equal to the first distance minus the second distance. The display is configured to report to a user the severable length of the object.
ROBOTIC SYSTEM AND METHOD OF MOVEMENT CONTROL USING SYNTHETIC ARRAY RADAR AND PASSIVE BEACONS
A system includes a moveable element adapted to move relative to a coordinate system defined for a robot, an object detection transceiver unit adapted to be mounted on the moveable element, and a controller. The controller controls the object detection transceiver unit to emit a signal and obtain a return signal for an operational cell of the robot at each of a series of predetermined positions to emulate a transceiver aperture larger than an aperture of the object detection transceiver unit. A location corresponding to a marker present in the operational cell is determined from the return signals. A predetermined operation is carried out where the predetermined operation includes using the determined location to guide movement of the robot.
Method and apparatus for laser projection, and machining method
A laser projection method including the steps of: irradiating, from a laser projection unit, a workpiece that is a measurement object, with a laser while controlling a plurality of mirror angles; imaging the workpiece with a stereo camera, extracting a contour of the workpiece, and calculating a three-dimensional coordinate; calculating a positional relationship between the laser projection unit and the workpiece by comparing the calculated three-dimensional coordinate of the workpiece contour with the minor angle; and performing coordinate transformation of CAD data information and drawing CAD data from the laser projection unit to the workpiece, based on the positional relationship between the laser projection unit and the workpiece. The machining method including the steps of: selecting a component of a tool; assembling the component; imaging the tool assembled; and determining whether or not a desired tool has been assembled.
Systems and methods for calibrating a LiDAR device
Systems and methods for calibrating a LiDAR device are disclosed. According to one embodiment, the system comprises a LiDAR device, a continuous curved target at a fixed distance from the LiDAR device, and a calibration controller operable to perform a reflectance over range calibration of the LiDAR device. The LiDAR device scans portions of the continuous curved target at different ranges during the calibration.
TECHNIQUES FOR DETECTING ERRORS OR LOSS OF ACCURACY IN A SURGICAL ROBOTIC SYSTEM
Systems and methods for operating a robotic surgical system are provided. The system includes a surgical tool, a manipulator comprising a base supporting links for controlling the tool, a navigation system comprising a tracker coupled to the tool and a localizer to monitor a state of the tracker. A controller acquires raw kinematic measurement data about a state of the tool relative to the base from the manipulator, known relationship data about the state of the tracker relative to the tool, and raw navigation data about the state of the tracker relative to the localizer from the navigation system. The controller combines this data to determine a raw relationship between the base and the localizer. The raw relationship is filtered for controlling the manipulator. The raw relationship or a less filtered version of the raw relationship is utilized to determine whether an error has occurred in the system.
