Mobile robot system

1. A method of operating a mobile robot, the method comprising:

receiving, at a data processing device, a layout map corresponding to an environment of the robot;

moving the robot in the environment to one or more layout map locations on the layout map;

recording, in non-transitory memory in communication with the data processing device, one or more robot map locations on a robot map, the robot map corresponding to the environment and produced by the robot;

determining, using the data processing device, a distortion between the robot map and the layout map using the recorded robot map locations of the robot map and the corresponding layout map locations of the layout map; and

applying, using the data processing device, the determined distortion to a target layout map location to determine a corresponding target robot map location.

2. The method of claim 1 , further comprising receiving, at the data processing device, the layout map from a cloud computing service.

3. The method of claim 2 , further comprising producing the layout map on an application executing on a remote computing device and storing the layout map on a remote cloud storage device using the cloud computing service.

4. The method of claim 1 , further comprising:

determining, using the data processing device, a scaling size, origin mapping, and rotation between the layout map and the robot map using existing layout map locations and recorded robot map locations; and

resolving, using the data processing device, a robot map location corresponding to the target layout map location.

5. The method of claim 4 , further comprising applying data processing device, an affine transformation to the determined scaling size, origin mapping, and rotation to resolve the target robot map location.

6. The method of claim 1 , further comprising determining, using the data processing device, a triangulation between layout map locations that bound the target layout map location.

7. The method of claim 6 , further comprising determining, using the data processing device, a scale, rotation, translation, and skew between a triangle mapped in the layout map and a corresponding triangle mapped in the robot map and applying the determined scale, rotation, translation, and skew to the target layout map location to determine the corresponding robot map point.

8. The method of claim 1 , further comprising:

determining, using the data processing device, distances between all layout map locations and the target layout map location;

determining, using the data processing device, a centroid of the layout map locations;

determining, using the data processing device, a centroid of all recorded robot map locations; and

for each layout map location, determining a rotation and a length scaling to transform a vector running from the layout map centroid to the target layout location into a vector running from the robot map centroid to the target robot map location.

9. The method of claim 1 , further comprising producing the robot map using a sensor system of the robot.

10. The method of claim 9 , further comprising

emitting light onto a scene of the environment;

receiving reflections of the emitted light off surfaces of the scene;

determining, using the data a distance of each reflecting surface; and

constructing, using the data processing device, a three-dimensional depth map of the scene.

11. The method of claim 10 , further comprising emitting a speckle pattern of light onto the scene and receiving reflections of the speckle pattern from the scene.

12. The method of claim 11 , further comprising storing, in the non-transitory memory, reference images of the speckle pattern as reflected off a reference object in the scene, the reference images captured at different distances from the reference object.

13. The method of claim 12 , further comprising capturing at least one target image of the speckle pattern as reflected off a target object in the scene and comparing the at least one target image with the reference images for determining a distance of the reflecting surfaces of the target object.

14. The method of claim 13 , further comprising determining a primary speckle pattern on the target object and computing at least one of a respective cross-correlation and a decorrelation between the primary speckle pattern and the speckle patterns of the reference images.

15. The method of claim 13 , further comprising maneuvering the robot with respect to the target object based on the determined distances of the reflecting surfaces of the target object.

16. The method of claim 10 , further comprising determining, using the data processing device, a time-of-flight between emitting the light and receiving the reflected light and determining, using the data processing device, a distance to the reflecting surfaces of the scene.

17. The method of claim 10 , further comprising emitting the light onto the scene in intermittent pulses.

18. The method of claim 17 , further comprising altering a frequency of the emitted light pulses.
