TECHNIQUE FOR DETERMINING A RADIUS OF A SPHERICALLY SHAPED SURFACE PORTION OF AN INSTRUMENT TIP

A method and device for determining a radius of a spherically shaped surface portion of a tip of an instrument. A first pose of a first tracker and a second pose of a second tracker may be determined while the spherically shaped surface portion is in abutment with a calibration structure. A reference position of a first reference point relative to the second tracker may be determined when the first tracker is in the first pose and the second tracker is in the second pose based on the first pose, the second pose, and a first predetermined relationship. A third pose of the first tracker and a fourth pose of the second tracker may be determined. The radius of the spherically shaped surface portion may be determined based on the third pose, a second predetermined relationship, a reference position, the fourth pose, and an opening angle.

20220117681 · 2022-04-21 ·

Devices, systems, and methods for automatically exchanging a first end-effector on a robot arm with a second end-effector housed in a docking station. The first end-effector has a clamp that either engages or disengages the robot arm based upon an application of force of the robot arm onto the end-effector. The clamp has a spring loaded clip that disengages the first end-effector to allow the robot arm to move away from the released first end-effector. The robot arm is configured to automatically move to a port of a docking station housing the desired second end-effector using magnetic coils on the robot arm and the docking station to guide the robot arm.

Apparatus and method for image guided accuracy verification

A method includes receiving during a first time interval associated with a path of motion of a dynamic body, image data associated with a plurality of images of the dynamic body. The plurality of images include an indication of a position of a first marker coupled to a garment at a first location, and a position of a second marker coupled to the garment at a second location. The garment is coupled to the dynamic body. During a second time interval, an image from the plurality of images is automatically identified that includes a position of the first marker that is substantially the same as a position of a first localization element relative to the dynamic body and a position of the second marker that is substantially the same as a position of the second localization element relative to the dynamic body.
