Abstract
An apparatus includes a pick head configured to transfer sample containers to and from a sample group holder, at least one sensor connected to the pick head and configured to detect at least one predetermined feature of the sample group holder, and a controller configured to receive a detection signal from the at least one sensor corresponding to detection of the at least one predetermined feature, determine a change in a predetermined characteristic of the sample group holder based on a detected position of the at least one predetermined feature, and determine a location of one or more samples in the sample group holder to allow for the transfer of the one or more sample containers to and from the sample group holder based on the edge detection signal.
