Method comprising:providing at least one vertical lift having at least one shelf (1000) having support fingers (1000F); providing reference datums (1620) on at least one wall (1100) adjacent the least one vertical lift, the reference datums (1620) being substantially aligned with the support fingers (1000F);sensing each of the reference datums with at least one sensor (700, 701) of an autonomous transport vehicle (110);aligning transfer arm fingers (110F) of a transfer arm (110A) of the autonomous transport vehicle (110) with spaces located between the support fingers (1000F) of the at least one shelf (1000) based on the determined location of the autonomous transport vehicle (110); and determining, with a controller, a location of the autonomous transport vehicle (110) relative to the support fingers (1000F) based on the output signal from the at least one sensor (700, 701). |
