Abstract

Claims (58)

1. A method, the method comprising:

transmitting a first signal to a perception system of a painting system to scan one or more surfaces of a wall assembly;

receiving sensor data from the perception system;

determining a relative position of the painting system and the one or more surfaces of the wall assembly based on the scanning; and

transmitting a second signal to a robotic arm of the painting system to move the robotic arm to apply a spray of paint from a painting end effector of the painting system to the one or more surfaces of the wall assembly based at least in part on the relative position, wherein the painting system creates a feathered paint edge by reducing an amount of the paint applied by the painting end effector at an edge of a first region of the one or more surfaces;

receiving further sensor data comprising paint flow rate data; and

transmitting a third signal to cause a flow of the paint through the painting end effector to reverse to clear a clog based on detecting a change in the further sensor data.

2. The method of claim 1 , further comprising:

transmitting a fourth signal to move the robotic arm to apply the spray of the paint from the painting end effector to the feathered paint edge and a second region of the one or more surfaces, wherein the second region is adjacent to the first region and the painting system blends the paint across the first region and the second region by reducing the amount of the paint applied by the painting end effector at the feathered paint edge.

3. The method of claim 1 , further comprising:

obtaining, from the perception system, paint application data identifying at least one of: one or more painted regions of the one or more surfaces, and one or more unpainted regions of the one or more surfaces.

4. The method of claim 1 , further comprising:

transmitting a fourth signal to a movement system to move the painting system to a location adjacent to the one or more surfaces of the wall assembly, wherein the movement compensates for error in the location relative to a target location.

5. The method of claim 1 , further comprising:

generating a map of the one or more surfaces of the wall assembly based at least in part on the scanning, wherein the determining the relative position of the painting system and the one or more surfaces of the wall assembly comprises determining a location of the painting system within the map.

6. The method of claim 1 , further comprising:

detecting a location of an object relative to the painting system; and

maintaining safety of the object by triggering a safety operation of the painting system based on the location of the object.

7. The method of claim 1 , further comprising:

initiating an application of the paint to the one or more surfaces of the wall assembly based on data obtained while the painting system was applying joint compound to one or more joints on the one or more surfaces of the wall assembly.

8. The method of claim 1 , further comprising:

transmitting a fourth signal to the robotic arm to move the robotic arm to blend the paint across adjacent painted regions by rolling the adjacent painted regions with a paint roller while the paint is wet.

9. A method, the method comprising:

transmitting a first signal to a perception system of a painting system to scan one or more surfaces of a wall assembly;

receiving sensor data from the perception system;

determining a relative position of the painting system and the one or more surfaces of the wall assembly based on the scanning;

transmitting a second signal to a robotic arm of the painting system to move the robotic arm to apply a spray of paint from a painting end effector of the painting system to the one or more surfaces of the wall assembly based at least in part on the relative position, wherein the painting system creates a feathered paint edge by reducing an amount of the paint applied by the painting end effector at an edge of a first region of the one or more surfaces;

receiving further sensor data comprising pressure data; and

transmitting a third signal to cause a flow of the paint through the painting end effector to reverse to clear a clog based on detecting a change in the further sensor data.

10. The method of claim 9 , further comprising:

transmitting a fourth signal to move the robotic arm to apply the spray of the paint from the painting end effector to the feathered paint edge and a second region of the one or more surfaces, wherein the second region is adjacent to the first region and the painting system blends the paint across the first region and the second region by reducing the amount of the paint applied by the painting end effector at the feathered paint edge.

11. The method of claim 9 , further comprising:

obtaining, from the perception system, paint application data identifying at least one of: one or more painted regions of the one or more surfaces, and one or more unpainted regions of the one or more surfaces.

12. The method of claim 9 , further comprising:

transmitting a fourth signal to a movement system to move the painting system to a location adjacent to the one or more surfaces of the wall assembly, wherein the movement compensates for error in the location relative to a target location.

13. The method of claim 9 , further comprising:

generating a map of the one or more surfaces of the wall assembly based at least in part on the scanning, wherein the determining the relative position of the painting system and the one or more surfaces of the wall assembly comprises determining a location of the painting system within the map.

14. The method of claim 9 , further comprising:

detecting a location of an object relative to the painting system; and

maintaining safety of the object by triggering a safety operation of the painting system based on the location of the object.

15. The method of claim 9 , further comprising:

initiating an application of the paint to the one or more surfaces of the wall assembly based on data obtained while the painting system was applying joint compound to one or more joints on the one or more surfaces of the wall assembly.

16. A method, the method comprising:

transmitting a first signal to a perception system of a painting system to scan one or more surfaces of a wall assembly;

receiving sensor data from the perception system;

determining a relative position of the painting system and the one or more surfaces of the wall assembly based on the scanning;

transmitting a second signal to a robotic arm of the painting system to move the robotic arm to apply a spray of paint from a painting end effector of the painting system to the one or more surfaces of the wall assembly based at least in part on the relative position, wherein the painting system creates a feathered paint edge by reducing an amount of the paint applied by the painting end effector at an edge of a first region of the one or more surfaces;

receiving further sensor data comprising image data; and

transmitting a third signal to cause a flow of the paint through the painting end effector to reverse to clear a clog based on detecting a change in the further sensor data.

17. The method of claim 16 , further comprising:

transmitting a fourth signal to move the robotic arm to apply the spray of the paint from the painting end effector to the feathered paint edge and a second region of the one or more surfaces, wherein the second region is adjacent to the first region and the painting system blends the paint across the first region and the second region by reducing the amount of the paint applied by the painting end effector at the feathered paint edge.
