[0036] A transceiver 62 is in communication with the processor 60. The transceiver 62 is configured to wirelessly communicate with a personal electronic device 64 wherein the transceiver 62 is configured to receive signals from the personal electronic device 64 to actuate the processor 60 whereby the transceiver 62 is configured to facilitate moving the housing 12 to a location of a user 66. For example, as shown in FIG. 7, the personal electronic device 64 may include a user interface that facilitates communication with the transceiver 62. The user interface may include a “call” button that signals the transceiver 62 to actuate the processor 60 to actuate the pivot motor 30 and the plurality of rotational motors 40 to move the housing 12 toward the location of the user 66.

[0037] An infrared sensor 68 is in communication with the processor 60. The infrared sensor 68 is generally configured to emit a light beam that reflects off an obstacle 78. The infrared sensor 68 may be positioned on the top wall 16 of the housing 12 wherein the infrared sensor 68 faces outwardly past the front side 26 of the housing 12.

[0038] A photoelectric sensor 70 is in communication with the processor 60. The photoelectric sensor 70 is generally configured to detect the light beam when the light beam is reflected off the obstacle 78 wherein the infrared sensor 68 and the photoelectric sensor 70 are configured to inhibit the housing 12 from colliding with the obstacle 78 when the housing 12 is moving to the location of the user 66. The processor 60 may actuate the infrared sensor 68 and the photoelectric sensor 70 when the processor 60 actuates the pivot motor 30 and the plurality of rotational motors 40 to facilitate the housing 12 in moving around the obstacle 78. The photoelectric sensor 70 may be positioned on the top wall 16 of the housing 12, for example proximate to the infrared sensor 68, wherein the photoelectric sensor 70 faces outwardly past the front side 26 of the housing 12.

[0039] The obstacle 78 may be a piece of furniture, a wall, a person, or another obstacle 78 with which the housing 12 may collide while it is moving toward the location of the user 66. For example, when the infrared sensor 68 and the photoelectric sensor 70 detect that the light beam is reflecting off the obstacle 78 while the obstacle 78 is within a certain distance of the housing 12 (such as 2.0 feet), the processor 60 may actuate the pivot motor 30 to adjust the direction in which the housing 12 is moving so that the housing 12 does not collide with the obstacle 78.

[0040] A display screen 80 may be in communication with the processor 60. The display screen 80 is generally configured to display a customizable message 82. The transceiver 62 may be configured to receive the customizable message 82 from the personal electronic device 64 wherein the transceiver 62 is configured to facilitate the user in creating the customizable message 82 for display on the display screen 80. The display screen 80 may be a light emitting diode display screen. As shown in the Figures, the display screen 80 may be positioned on the top wall 16 of the housing 12. For example, the display screen 80 may surround the infrared sensor 68 and the photoelectric sensor 70. Accordingly, in certain embodiments, the infrared sensor 68 and the photoelectric sensor 70 may resemble a pair of eyes looking out from the top wall 16 through the display screen 80.

[0041] A power source 72 may be electrically coupled to the processor 60. The power source 72 may also be electrically coupled to the transceiver 62. The power source 72 may be a battery, such as a rechargeable battery.

[0042] A charging port 74 may be electrically coupled to the power source 72. The charging port 74 is generally configured to be electrically couplable to a docking station 75 wherein the charging port 74 is configured to transfer power from the docking station 75 to the power source 72. For example, as shown in FIG. 5, the docking station 75 may be positioned on a wall and electrically coupled to a power generator. In certain embodiments, the processor 60 may draw power directly from the docking station 75 while the charging port 74 is coupled to the docking station 75, rather than drawing power from the power source 72. In other embodiments, the processor 60 may inhibit the power source 72 from directing power to the refrigeration unit 50 while the charging port 74 is disconnected from the docking station 75 such that the power source 72 only directs power to the pivot motor 30, the plurality of rotational motors 40, the infrared sensor 68, and the photoelectric sensor 70. The processor 60 may be configured to actuate the refrigeration unit 50 while the charging port 74 is coupled to the docking station 75.

[0043] A plurality of shelves 76 may be positioned within the housing 12. The plurality of shelves 76 may be spaced from each other between the top wall 16 and the bottom wall 18 wherein the plurality of shelves 76 are configured to support an object that is positioned within the interior space 14 For example, the object may be a beverage container, as shown in FIG. 6, although food containers and other items are also contemplated.

[0044] In use, the infrared sensor 68 and the photoelectric sensor 70 can scan the room or area where the housing 12 is stored to learn where the obstacle 78 is located. In some embodiments, the processor 60 may have, or be in communication with, a memory unit that can store a location of the obstacle 78 whereby the motorized refrigeration device can learn a layout of the room or area where the housing 12 is being stored. Once the housing 12 disconnects from the docking station 75, the processor 60 may deactivate the refrigeration unit 50 to reduce the amount of power that is being drained from the power source 72. When the personal electronic device 64 signals the transceiver 62, the transceiver 62 signals the processor 60 to actuate the pivot motor 30 and the plurality of rotational motors 40. When the infrared sensor 68 and the photoelectric sensor 70 locate the obstacle 78, the processor 60 will signal the pivot motor 30 and the plurality of rotational motors 40 to adjust the direction in which the housing 12 is moving to inhibit the housing 12 from colliding with the obstacle 78 until the housing 12 arrives at the location of the user 66.

[0045] The processor 60 may automatically actuate the pivot motor 30 and the plurality of rotational motors 40 after a set amount of time to move the housing 12 back to the charging port 74. Alternatively, the user interface on the personal electronic device 64 may include a “home” or “return” button for signaling the processor 60 to actuate the pivot motor 30 and the plurality of rotational motors 40 to move the housing 12 back to the docking station 75. When the housing 12 is connected to the docking station 75, the processor 60 may actuate the refrigeration unit 50 to cool the interior space.

[0046] With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

[0047] Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
