Claim 9:
10. A method for scanning a shopping space comprising:
providing a locomotion system of a motorized unit configured to navigate the motorized unit in the shopping space and track a location of the motorized unit, the locomotion system comprises a locomotion controller, a motor, and a first transceiver;
providing a camera system of the motorized unit configured to capture images, the camera system comprises an image sensor, a second transceiver, and a camera processor configured to extract item identifiers from the images captured by the image sensor; and
providing a central computer system communicatively coupled to the locomotion system and the camera system over a wireless network;
receiving, at the central computer system, motorized unit location information from a first transceiver of a locomotion system of a motorized unit, the motorized unit location information comprises a plurality of sets of coordinates each associated with a timestamp;
receiving, at the central computer system, item identifier instances from a second transceiver of the camera system of the motorized unit, each item identifier instance being associated with a timestamp, and wherein the second transceiver communicates with a central computer system independent of the first transceiver; and
determining, at the central computer system, a location for each item identifier instance based on the timestamps associated with the item identifier instances received from the second transceiver and the timestamps associated with the plurality of sets of coordinates of the motorized unit location information received from the first transceiver, wherein the first transceiver and the second transceiver are both located on the motorized unit and both wirelessly transmit data to the central computer system remote to the motorized unit.
