Abstract
A medical system includes a robot with a robotic arm, a flange control unit coupled to the robotic arm's distal end and including a laser, a navigation system with a camera to capture surface images, and an electronic processor. The processor performs a calibration routine by controlling the arm to move to a first position, activating the laser to illuminate a first surface point, processing an image of a tracked pointer at the first point to determine a first tool center point, moving the arm to a second position, illuminating a second point, processing an image to determine a second tool center point, and determining a calibrated tool center point based on the first and second points. The processor may control the arm based on the calibrated tool center point.
