Claim 24:
25. A method of a controller to control operation of a robotic handler, the robotic handler including a sensor configured to generate a field detection signal when in a near vicinity of a fiducial beacon in a workspace of an automated apparatus for biological sample preparation, preprocessing and/or diagnostic assay performed by one or more analyzers of the automated apparatus, the method comprising:
controlling moving of the robotic handler in the workspace of the automated apparatus in a search pattern, the search pattern comprising first movement along a first axis in a first direction;
sensing, during the first movement of the search pattern, so as to receive, via the sensor coupled to the robotic handler, the field detection signal produced in a near vicinity of the fiducial beacon, and to determine a first count on the first axis correlating with a location of a first detection of the fiducial beacon during the first movement,
controlling moving of the robotic handler in the workspace of the automated apparatus in the search pattern, the search pattern comprising a second movement along the first axis in a second direction, the second direction opposite the first direction;
sensing, during the second movement of the search pattern, so as to receive, via the sensor coupled to the robotic handler, the field detection signal produced in a near vicinity of the fiducial beacon, and to determine a second count on the first axis correlating with a location of a second detection of the fiducial beacon during the second movement; and
calculating a third count on the first axis based on the first count and the second count, the third count correlating with a location of the fiducial beacon on the first axis.
