Abstract
Technologies for calibrating a pan tilt unit with a robot include a robot controller to move a camera of the pan tilt unit about a first rotational axis of the pan tilt unit to at least three different first axis positions. The robot controller records a first set of positions of a monitored component of the robot in a frame of reference of the robot and a position of the camera in a frame of reference of the pan tilt unit during a period in which the monitored component is within a field of view of the camera for each of the at least three different first axis positions. Further, the robot controller moves the camera about a second rotational axis of the pan tilt unit to at least three different second axis positions and records a second set of positions of the monitored component in the frame of reference of the robot and a position of the camera in the frame of reference of the pan tilt unit during a period in which the monitored component is within a field of view of the camera for each of the at least three different second axis positions. Further, the robot controller determines a transformation from the frame of reference of the robot to the frame of reference of the pan til…
