Abstract

A method of cleaning an area using an automatic cleaning device may include receiving, from a video camera, information associated with an edge located on a surface, determining, by an automatic cleaning device, a position of the automatic cleaning device on the surface relative to the edge and using the received information to move the automatic cleaning device from the determined position along a path so that the automatic cleaning device cleans the surface along the path. The path may be substantially parallel to the edge, and the edge may be located a distance from a reference point on the automatic cleaning device during movement of the automatic cleaning device.

Claims (39)

1. A method of cleaning an area using an automatic cleaning device, the method comprising:

receiving, from a video camera, information associated with an edge located on a surface of the area, wherein the edge is substantially straight;

by an automatic cleaning device, using the information received from the video camera to determine a position of the automatic cleaning device on the surface relative to the edge;

receiving positional information from a sensor of the automatic cleaning device;

comparing the determined position using the information received from the video camera with the positional information received from the sensor to determine which has a least amount of error relative to a current position of the automatic cleaning device, wherein the current position is determined using a digital map of the area; and

if the determined position has the least amount of error, using the received information to move the automatic cleaning device from the determined position along a path so that the automatic cleaning device cleans the surface along the path, wherein the path is substantially parallel to the edge, wherein the edge is located a distance from a reference point on the automatic cleaning device during movement of the automatic cleaning device;

otherwise using the positional information from the sensor to adjust a position of the automatic cleaning device.

2. The method of claim 1 , wherein the receiving information comprises receiving information in response to a request for information from the automatic cleaning device to the video camera.

3. The method of claim 1 , wherein the receiving information comprising receiving one or more of the following:

a slope associated with the edge;

an intercept associated with the edge; and

an error associated with the edge.

4. The method of claim 1 , wherein the receiving information associated with an edge comprises continuously receiving information from the video camera over a period of time.

5. The method of claim 1 , wherein cleaning the surface along the path comprises:

determining one or more characteristics associated with the surface along the path;

determining a cleaning method based on the determined one or more characteristics; and

applying the cleaning method to the surface along the path.

6. The method of claim 5 , wherein determining one or more characteristics comprises determining that surface along the path comprises one or more of the following:

hard wood flooring;

tile flooring;

carpeting;

a high-traffic area; and

a low-traffic area.

7. The method of claim 5 , wherein applying a cleaning method comprises performing one or more of the following:

vacuuming the surface along the path;

scrubbing the surface along the path; and

waxing the surface along the path.

8. The method of claim 1 , wherein the edge corresponds to one or more of the following:

an edge between two adjoining rooms,

an edge of a carpet on the surface of the area;

an edge between different floor types on the surface of the area.

9. A method of cleaning an area using an automatic cleaning device, the method comprising:

receiving, from a video camera, information associated with an edge located on a surface of the area, wherein the edge is substantially straight;

by an automatic cleaning device, using the information received from the video camera to determine a position of the automatic cleaning device on the surface relative to the edge;

receiving positional information from a sensor of the automatic cleaning device, and

comparing the determined position using the information received from the video camera with the positional information received from the sensor to determine which has a least amount of error relative to a current position of the automatic cleaning device, wherein the current position is determined using a digital map of the area; and

if the determined position has the least amount of error, using the received information to adjust the determined position of the automatic cleaning device based on a proximity of the automatic cleaning device to the edge;

otherwise using the positional information from the sensor to adjust a position of the automatic cleaning device.

10. The method of claim 9 , wherein receiving information associated with an edge comprises receiving information associated with an edge located substantially perpendicular to the automatic cleaning device's movement.
