Abstract

Systems, apparatuses, and methods for scanning a shopping space. The system pace comprises a locomotion system of a motorized unit, a camera system, and a central computer system. The central computer system is configured to receive motorized unit location information from the locomotion system, the motorized unit location information comprises a plurality of sets of coordinates each associated with a timestamp, receive item identifier instances from the camera system, wherein each item identifier instance is associated with a timestamp, and determine a location for each item identifier instance based on the timestamps associated of the item identifier instances and the timestamps associated with the plurality of sets of coordinates of the motorized unit location information.
