Abstract

The systems and methods of automatically cleaning a wheel are disclosed herein. The systems and methods include a foreign matter detector arranged adjacent to the wheel, a cleaning device arranged adjacent to the wheel, one or more processors communicatively coupled to the foreign matter detector and the cleaning device; and a non-transitory, processor-readable storage medium communicatively coupled to the one or more processors. The non-transitory, processor-readable storage medium includes one or more programming instructions stored thereon that, when executed, cause the one or more processors to: receive a signal from the foreign matter detector, the signal being indicative of possible foreign matter present on a surface of the wheel, determine from the signal, whether foreign matter is present on the wheel, and direct the cleaning device to remove the foreign matter from the wheel.

First claim

What is claimed is:

1. A system, comprising:
a foreign matter detector coupled to a structure having a wheel;
a cleaning device coupled to the structure adjacent to the wheel without contacting the wheel;
a module communicatively coupled to the foreign matter detector and the cleaning device and configured to:
receive a signal from the foreign matter detector indicative of possible foreign matter present on the wheel;
determine, from the signal, that foreign matter is present on the wheel; and
direct the cleaning device to remove the foreign matter from the wheel without contacting the wheel.

2. The system of claim 1 , wherein the signal indicates an amount of foreign matter on the wheel and determining that foreign matter is present on the wheel comprises:
determining whether the amount of the foreign matter is greater than a threshold; and
directing the cleaning device to clean the wheel in response to the amount of the foreign matter exceeding the threshold.

3. The system of claim 1 , wherein the cleaning device comprises a vibration mechanism, a heater element, a solvent applicator, and/or a blower.

4. The system of claim 1 , wherein the structure is a wheelchair.

5. The system of claim 1 , wherein the structure is a mobile robot system.

6. The system of claim 1 , further comprising: a transition detector communicatively coupled to the module, wherein the module is further configured to:
receive a transition signal indicative of the wheel approaching a transition from an outdoor environment to an indoor environment; and
direct the cleaning device to clean the wheel in response to the transition signal.

7. The system of claim 1 , wherein the module is further configured to direct the cleaning device to clean the wheel until a sensed amount of the foreign matter is below a threshold.

8. A method of cleaning a wheel, the method comprising:
receiving a signal, by a module from a foreign matter detector coupled to a structure having the wheel, the signal indicative of possible foreign matter present on the wheel;
determining from the signal that foreign matter is present on the wheel; and
directing a cleaning device coupled to the structure and adjacent to the wheel without contacting the wheel to remove the foreign matter from the wheel without contacting the wheel wherein the module is communicatively coupled to the foreign matter detector and the cleaning device.

9. The method of claim 8 , wherein the signal indicates an amount of foreign matter on the wheel and determining that foreign matter is present on the wheel comprises:
determining whether the amount of the foreign matter is greater than a threshold; and
directing the cleaning device to clean the wheel in response to an amount of the foreign matter exceeding the threshold.

10. The method of claim 8 , further comprising:
receiving a transition signal indicative of the wheel approaching a transition from an outdoor environment to an indoor environment; and
directing the cleaning device to clean the wheel in response to the transition signal.

11. The method of claim 8 , further comprising:
directing the cleaning device to clean the wheel until a sensed amount of the foreign matter is below a threshold.

12. The method of claim 8 , further comprising:
receiving a user input signal requesting to clean the wheel; and
directing the cleaning device to clean the wheel in response to the user input signal being received.

13. A system for automatically cleaning one or more wheels, comprising:
a mobile utility machine having one or more wheels;
at least one foreign matter detector coupled to the mobile utility machine and positioned adjacent to the one or more wheels;
at least one cleaning device coupled to the mobile utility machine and arranged adjacent to at least one of the one or more wheels without contacting the at least one of the one or more wheels; and
a cleaning determination module communicatively coupled to the at least one foreign matter detector and the at least one cleaning device and configured to:
receive a signal from the at least one foreign matter detector indicative of possible foreign matter present on at least one of the one or more wheels,
determine from the signal that the foreign matter is present on at least one of the one or more wheels, and
direct the at least one cleaning device to remove the foreign matter from the at least one of the one or more wheels without contacting the at least one of the one or more wheels.

14. The system of claim 13 , wherein the signal indicates an amount of foreign matter on the at least one of the one or more wheels and determining that foreign matter is present on the at least one of the one or more wheels comprises:
determining whether the amount of the foreign matter is greater than a threshold; and
directing the at least one cleaning device to clean the one or more wheels in response to an amount of the foreign matter exceeding the threshold.

15. The system of claim 13 , wherein the at least one cleaning device comprises a vibration mechanism, a heater device, a solvent spraying device, and/or a blowing device.

16. The system of claim 13 , wherein the mobile utility machine is a mobile robot.

17. The system of claim 13 , wherein the mobile utility machine is a wheelchair.

18. The system of claim 13 , wherein the cleaning determination module is further configured to receive an image indicative of the foreign matter present on the at least one of the one or more wheels, determine an amount of the foreign matter on the at least one of the one or more wheels based on the image, determine whether the amount of the foreign matter is greater than a threshold, and direct the at least one cleaning device to clean the at least one of the one or more wheels when the amount of the foreign matter exceeds the threshold.

19. The system of claim 13 , further comprising: a user input device communicatively coupled to the cleaning determination module, wherein the cleaning determination module is further configured to receive a clean signal, from the user input device, and direct the at least one cleaning device to clean the at least one of the one or more wheels in response to receiving the clean signal.

20. The system of claim 13 , further comprising: a transition device communicatively coupled to the cleaning determination module, wherein the cleaning determination module is further configured to receive a transition signal, from the transition device, indicating that the mobile utility machine is approaching a transition from an outdoor environment to an indoor environment, and direct the at least one cleaning device to clean the at least one of the one or more wheels, in response to receiving the transition signal.
