Abstract

A system for enabling spot cleaning includes a mobile computing device and a mobile cleaning robot. The mobile computing device includes at least one camera configured to capture images of an environment, and at least one data processor configured to (a) establish, based at least in part on first information provided by the at least one image sensor, a coordinate system in the environment, (b) determine, based at least in part on second information provided by the at least one camera, a first set of coordinates of a region at a first location, (c) determine, based at least in part on third information provided by the at least one camera, a second set of coordinates of a mobile cleaning robot at a second location, (d) send the first set of coordinates and second set of coordinates, or coordinates of the first location relative to the second location, to the mobile cleaning robot, and (e) send an instruction to the mobile cleaning robot to request the mobile cleaning robot to travel to the first location.

First claim

What is claimed is:

1. A method for spot cleaning using a mobile cleaning robot, the method comprising:
generating, by the mobile cleaning robot, an indication that a location in an interior environment was not cleaned by the mobile cleaning robot;
receiving, at the mobile cleaning robot, an indication of a user-defined path from a first location to a second location in the interior environment, wherein the second location corresponds to the location that was not cleaned by the mobile cleaning robot;
by the mobile cleaning robot, traversing a floor surface of the interior environment along the user-defined path from the first location to the second location; and
by the mobile cleaning robot, performing a cleaning operation at the second location.

2. The method of claim 1 , wherein the first location is a location of the mobile cleaning robot at the time of receiving the indication of the user-defined path.

3. The method of claim 1 , wherein receiving the indication of the user-defined path comprises receiving, from a mobile computing device, data representative of a virtual path defined by the user using the mobile computing device.

4. The method of claim 3 , wherein the virtual path corresponds to a drawing made by the user on a map presented on a display of the mobile computing device.

5. The method of claim 1 , wherein receiving the indication of the user-defined path comprises receiving, from a mobile computing device, coordinates corresponding to a path traveled by the user from the first location to the second location.

6. The method of claim 5 , wherein the coordinates are coordinates of the mobile computing device.

7. The method of claim 6 , wherein the coordinates of the mobile computing device are determined using visual-inertial odometry.

8. The method of claim 1 , wherein receiving the indication of the user-defined path comprises:
receiving an instruction to follow the user, and
responsive to receiving the instruction, determining a path traveled by the user from the first location to the second location.

9. The method of claim 8 , wherein determining the path traveled by the user from the first location to the second location comprises:
capturing images of the user while the user travels from the first location to the second location,
analyzing the images to identify the user, and
determining, from the images, a direction in which the user is moving.

10. A mobile cleaning robot comprising:
one or more processing devices configured to generate an indication that a location on a floor surface was not cleaned by the mobile cleaning robot;
a communication module configured to receive an indication of a user-defined path from a first location to a second location on the floor surface, wherein the second location corresponds to the location that was not cleaned by the mobile cleaning robot;
a drive operable to move the mobile cleaning robot across the floor surface along the user-defined path from the first location to the second location; and
a cleaning assembly configured to clean the floor surface at the second location.

11. The mobile cleaning robot of claim 10 , wherein the first location is a location of the mobile cleaning robot at the time of receiving the indication of the user-defined path.

12. The mobile cleaning robot of claim 10 , wherein the indication of the user-defined path comprises data received from a mobile computing device, the data representative of a virtual path defined by the user.

13. The mobile cleaning robot of claim 12 , wherein the virtual path corresponds to a drawing made by the user on a map presented on a display of the mobile computing device.

14. The mobile cleaning robot of claim 10 , wherein the indication of the user-defined path comprises data received from a mobile computing device, the data representative of coordinates corresponding to a path traveled by the user from the first location to the second location.

15. The mobile cleaning robot of claim 14 , wherein the coordinates are coordinates of the mobile computing device.

16. The mobile cleaning robot of claim 15 , wherein the coordinates of the mobile computing device are determined using visual-inertial odometry.

17. The mobile cleaning robot of claim 10 , wherein the indication of the user-defined path comprises an instruction to follow the user.

18. The mobile cleaning robot of claim 10 , further comprising a camera configured to capture images of the user while the user travels from the first location to the second location.

19. The mobile cleaning robot of claim 18 , further comprising an image analysis module configured to analyze the images to identify the user and determine a direction in which the user is moving.

20. A system for enabling spot cleaning, the system comprising:
a mobile computing device comprising at least one data processor communicatively coupled to a storage device storing processor-executable instructions, in which upon execution of the processor-executable instructions by the at least one data processor, the at least one data processor is configured to transmit, to a mobile cleaning robot, an indication of a user-defined path from a first location to a second location on a floor surface, and
the mobile cleaning robot comprising:
one or more processing devices configured to generate an indication that a location on the floor surface was not cleaned by the mobile cleaning robot;
a communication module configured to receive, from the mobile computing device, the indication of the user-defined path from the first location to the second location on the floor surface, wherein the second location corresponds to the location that was not cleaned by the mobile cleaning robot;
a drive operable to move the mobile cleaning robot along the user-defined path from the first location to the second location; and
a cleaning assembly configured to clean the floor surface at the second location.
