1 . A cart for transporting a plurality of items at a product storage facility, the cart comprising:
a frame;
wheels mounted to and supporting the frame;
at least one support member mounted to the frame and configured to support ambient-temperature items thereon;
a refrigerator compartment mounted to at least one of the frame and the at least one support member and configured to store chilled items therein; and
a freezer compartment mounted to at least one of the frame and the at least one support member and configured to store frozen items therein.
2 . The cart of claim 1 , wherein the at least one support member is configured to support a plurality of bags containing the ambient-temperature items therein.
3 . The cart of claim 1 , wherein the refrigerator compartment and the freezer compartment are non-detachably mounted to at least one of the frame and the at least one support member.
4 . The cart of claim 3 , further comprising at least one power source configured to provide electrical power to at least one of the refrigerator compartment and the freezer compartment.
5 . The cart of claim 3 , wherein each of the refrigerator compartment and the freezer compartment includes a temperature sensor, and wherein each of the refrigerator compartment and the freezer compartment is configured to be:
in standby mode when the temperature sensor detects that a temperature in an interior of a respective one of the refrigerator compartment and the freezer compartment is at or below a minimum temperature required by the chilled items or the frozen items; and
in active cooling mode when the temperature sensor detects that the temperature in the interior of the respective one of the refrigerator compartment and the freezer compartment is above the minimum temperature required by the chilled items or the frozen items.
6 . The cart of claim 1 , wherein the cart includes a first light coupled to the frame and configured to turn on to indicate that a given one of the items is to be loaded onto the cart.
7 . The cart of claim 6 , wherein the first light is configured to turn on to indicate that the given one of the items is to be removed from the cart.
8 . The cart of claim 6 , wherein the cart includes a plurality of second lights, each of the second lights being positioned adjacent a respective one of the at least one support member, the refrigerator compartment and the freezer compartment, and wherein one of the second lights is configured to turn on to indicate whether the given one of the items is to be loaded onto the at least one support member, into the refrigerator compartment, or into the freezer compartment.
9 . The cart of claim 1 , wherein the cart is configured to be coupled to a robotic transport unit including a processor-based control circuit and configured to:
mechanically engage the cart and to move the cart about the product storage facility when mechanically engaged to the cart; and
mechanically disengage from the cart and to move toward and mechanically engage a second cart for moving the second cart about the product storage facility.
10 . The cart of claim 9 , wherein the robotic transport unit includes a transceiver configured to receive a control signal that causes the control circuit to cause movement of the wheels of the cart and navigate the cart to a destination indicated in the control signal.
11 . A method for transporting a plurality of items at a product storage facility via a cart that includes wheels mounted to and supporting a frame, the method comprising:
supporting, on at least one support member of a cart, one or more ambient-temperature items;
storing, within a refrigerator compartment mounted to at least one of the frame and the at least one support member, one or more chilled items;
storing, within a freezer compartment mounted to at least one of the frame and the at least one support member, one or more frozen items; and
transporting the plurality of items at the product storage facility via the cart.
12 . The method of claim 11 , wherein the refrigerator compartment and freezer compartment are non-detachably mounted to at least one of the frame and the at least one support member.
13 . The method of claim 12 , further comprising providing electrical power to at least one of the refrigerator compartment and the freezer compartment via at least one power source.
14 . The method of claim 12 , each of the refrigerator compartment and the freezer compartment includes a temperature sensor, and further comprising:
keeping the refrigerator compartment or the freezer compartment in standby mode when the temperature sensor detects that a temperature in an interior of a respective one of the refrigerator compartment and the freezer compartment is at or below a minimum temperature required by the chilled items or the frozen items; and
switching the first storage compartment or the second storage compartment to active cooling mode when the temperature sensor detects that the temperature in the interior of the respective one of the refrigerator compartment and the freezer compartment is above the minimum temperature required by the chilled items or the frozen items.
15 . The method of claim 11 , further comprising turning on a first light coupled to the frame of the cart in a first color to indicate that one of the items is to be loaded onto the cart.
16 . The method of claim 15 , further comprising turning on the first light in a second color to indicate that one of the items is to be removed from the cart.
17 . The method of claim 15 , further comprising providing the cart with a plurality of second lights, each of the second lights being positioned adjacent a respective one of the at least one support member, the refrigerator compartment and the freezer compartment, and wherein one of the second lights is configured to turn on to indicate whether a given one of the items is to be loaded onto the at least one support member, into the refrigerator compartment, or into the freezer compartment.
18 . The method of claim 11 , further comprising:
providing a robotic transport unit including a processor-based control circuit and, by the robotic transport unit:
mechanically engaging the cart to move the cart about the product storage facility when mechanically engaged to the cart; and
mechanically disengaging from the cart to move toward and mechanically engage a second cart for moving the second cart about the product storage facility.
19 . The method of claim 18 , further comprising providing the robotic transport unit with a transceiver configured to receive a control signal that causes the control circuit to cause movement of the wheels of the cart and navigate the cart to a destination indicated in the control signal.
20 . A method for transporting a plurality of items at a product storage facility, the method comprising:
transporting the plurality of items at the product storage facility via a cart, the cart including:
a frame;
wheels mounted to and supporting the frame;
at least one support member mounted to the frame and configured to support ambient-temperature items thereon;
a refrigerator compartment mounted to at least one of the frame and the at least one support member and configured to store chilled items therein; and
a freezer compartment mounted to at least one of the frame and the at least one support member and configured to store frozen items therein.
