Beschreibung
Zusammenfassung:	A storage and retrieval system including a storage structure having storage shelves, each storage shelf having slats for supporting stored items where the slats are spaced apart from each other by a predetermined distance, an autonomous transport vehicle including at least one sensor configured to sense each of the slats and output a signal indicating when a slat is sensed, and a controller for verifying a location of the autonomous transport vehicle within the storage structure based on at least the output signal.
