Abstract

Claims (40)

1 . A computer implemented method for determining item availability in a shopping space comprising:

receiving, at a control circuit, a request for an item for purchase;

causing, via the control circuit, a motorized transport unit having a locomotion system to travel to a display space in a shopping space, the display space intended to stock multiple items, including the item for purchase;

capturing, via one or more sensors of the motorized transport unit, image data of at least a portion of the display space;

based on the image data obtained during the capturing step, determining, via the control circuit, whether the item for purchase is available in the display space; and

in the event the item is not available in the display space, determining, with the control circuit, an alternative display space for the item for purchase;

causing a locomotion system of the motorized transport unit to travel to the alternative display space; and

determining, based on additional image data captured by the motorized transport unit at the alternative display space, whether the item for purchase is available at the alternative display space.

2 . The method of claim 1 , wherein the request for the item for purchase comprises a verbal command issued to the motorized transport unit, a shopping list entered at a user interface device, or an item selected through the user interface device.

3 . The method of claim 1 , wherein the one or more sensors of the motorized transport unit further captures a barcode scan, a radio frequency identification (RFID) scan, and/or an environmental temperature of the display space.

4 . The method of claim 1 , wherein the determining that the item is available in the display space is based on a presence of the item, an appearance of the item, an expiration date of the item, an appearance of the display space, and/or a storage environment of the item.

5 . The method of claim 1 , further comprising: instructing the motorized transport unit to travel to the alternative display space.

6 . A system for determining item availability in a shopping space comprising:

a communication device configured to communicate with a motorized transport unit including a locomotion system;

an inventory database storing inventory information of a plurality of items available for purchase in the shopping space; and

a control circuit coupled to the communication device and the inventory database, the control circuit being configured to:

receive a request for an item for purchase;

cause the motorized transport unit to travel a display space in the shopping space, the display space intended to stock multiple items, including the item for purchase;

receive, from via one or more sensors of the motorized transport unit, image data of at least a portion of the display space;

based on the image data obtained during the capturing step, determine, whether the item for purchase is available in the display space; and

in the event the item is not available in the display space, determine an alternative display space for the item for purchase and cause the motorized transport unit to travel to the alternative display space; and

determine, based on additional image data captured by the motorized transport unit at the alternative display space, whether the item for purchase is available at the alternative display space.

7 . The system of claim 6 , wherein the request for the item for purchase comprises one or more of: a verbal command issued to the motorized transport unit, a shopping list entered at a user interface device, and an item selected through the user interface device.

8 . The system of claim 6 , wherein the one or more sensors of the motorized transport unit further captures a barcode scan, a radio frequency identification (RFID) scan, and/or an environmental temperature of the display space.

9 . The system of claim 6 , wherein the determination that the item is available in the display space is based one or more of: a presence of the item, an appearance of the item, an expiration date of the item, an appearance of the display space, and a storage environment of the item.

10 . The system of claim 6 , wherein the control circuit is further configured to instruct the motorized transport unit to travel to the alternative display space.

11 . An apparatus for determining item availability in a shopping space comprising:

a wireless transceiver configured to communicate with a central computer system;

a motorized wheel system;

a user interface device;

a sensor;

a control circuit coupled to the wireless transceiver, the motorized wheel system, the user interface device, and the sensor, the control circuit being configured to:

travel, via the motorized wheel system and according to a determined route, to a display space in a shopping space stocking multiple items, including an item for purchase requested by a user;

captured, via the sensor, image data of at least a portion of the display space;

in the event the item is not available in the display space based on the image data, cause the motorized wheel system to travel to an alternative display space for the item for purchase; and

determine, based on additional image data captured by the sensor the alternative display space, whether the item for purchase is available at the alternative display space.

12 . The apparatus of claim 11 , wherein the determined route to the display space is received from the central computer system.

13 . The apparatus of claim 11 , wherein the determined route to the display space is determined by the control circuit in response to a location of the display space received from the control circuit.

14 . The apparatus of claim 11 , further comprising one or more sensors for capturing a barcode scan, a radio frequency identification (RFID) scan, and/or an environmental temperature of the display space.

15 . The apparatus of claim 11 , wherein the determination that the item is available in the display space is based one or more of: a presence of the item, an appearance of the item, an expiration date of the item, an appearance of the display space, and a storage environment of the item.
