Claim 13:
14. A processor-readable medium, having stored thereon processor-executable instructions which, when executed by a processor, cause the processor to control operation of a controller 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 processor-executable instructions comprising:
a control module configured to control moving, via the controller, the robotic handler in the workspace of the automated apparatus, the moving comprising a search pattern, the search pattern comprising first movement along a first axis in a first direction, the search pattern further comprising a second movement along the first axis in a second direction, the second direction opposite the first direction;
a sensing module configured to control, during the search pattern, receiving, via the sensor coupled to the robotic handler, the field detection signal produced in a near vicinity of the fiducial beacon, the sensing module configured 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, the sensing module further configured 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
a position calculating module configured to calculate 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.
