Paint repurposing system

1. A system comprising:

a reservoir configured to hold paint;

a sprayer coupled to the reservoir and configured to spray the paint onto a surface;

a controller circuit configured to selectively control a position of the sprayer relative to the substrate and to selectively deliver the paint to the surface to produce a workpiece formed of a plurality layers of the paint; and

a cutting attachment including a cutting blade configured to cut the workpiece;

wherein the controller circuit is configured to selectively control a position and rotation of the cutting blade relative to the substrate to carve the workpiece into a plurality of portions.

2. The system of claim 1 , further comprising:

a structure configured to secure the reservoir, the sprayer, and the control circuit, the structure including:

at least one frame element extending substantially vertically relative to the substrate; and

a crossbar coupled to the at least one frame element.

3. The system of claim 2 , further comprising:

a drive wheel coupled to the structure; and

a motor coupled to the drive wheel and to the controller circuit, the motor configured to turn the drive wheel to selectively adjust a position of the structure relative to the substrate.

4. The system of claim 2 , further comprising a plurality of grooves on at least one surface of the crossbar.

5. The system of claim 4 , further comprising a transverse alignment motor configured to couple the sprayer to the crossbar, the transverse alignment motor including a gear configured to engage one or more of the plurality of grooves and responsive to control signals from the controller circuit to move the sprayer relative to the crossbar to adjust a position of the sprayer relative to the substrate during operation.

6. The system of claim 2 , further comprising;

a first pulley positioned at a first end of the crossbar;

a second pulley positioned at a second end of the crossbar;

a string extending between the first pulley and the second pulley; and

a transverse alignment mechanism coupled to the sprayer and to the string, the transverse alignment mechanism configured to selectively position the sprayer relative to the substrate during operation.

7. The system of claim 6 , further comprising a motor coupled to one of the string and the transverse alignment mechanism and responsive to control signals from the controller circuit to adjust a position of the sprayer.

8. The system of claim 1 , further comprising a pump coupled to the reservoir and responsive to the controller circuit to deliver paint to the sprayer.

9. An apparatus comprising:

a reservoir configured to hold paint;

a structure including a crossbar extending parallel to a substrate to be painted and including at least one frame element extending substantially perpendicular to the substrate, the structure configured to move back in forth relative to the substrate and in a direction that is substantially perpendicular to the crossbar;

a sprayer coupled to the reservoir and configured to direct paint toward the substrate;

a transverse alignment mechanism coupled to the crossbar and to the sprayer, the transverse alignment mechanism configured to move the sprayer back and forth along the crossbar; and

a cutting attachment including a cutting blade configured to cut the workpiece.

10. The apparatus of claim 9 , further comprising a controller circuit configured to automatically control movement of the structure and movement of the transverse alignment mechanism.

11. The apparatus of claim 10 , further comprising a transverse alignment motor coupled to the transverse alignment mechanism and configured to adjust a position of the sprayer relative to the substrate in response to a control signal from the controller circuit.

12. The apparatus of claim 11 , further comprising:

a plurality of grooves on at least one surface of the crossbar; and

the transverse alignment motor including a gear configured to engage one or more of the plurality of grooves to move the sprayer relative to the crossbar to adjust a position of the sprayer relative to the substrate during operation.

13. The apparatus of claim 11 , further comprising;

a first pulley positioned at a first end of the crossbar;

a second pulley positioned at a second end of the crossbar;

a string extending between the first pulley and the second pulley; and

wherein the transverse alignment mechanism is coupled to the string and configured to selectively position the sprayer relative to the substrate during operation.

14. The apparatus of claim 10 , further comprising:

a drive wheel coupled to the structure and configured to contact the substrate; and

a drive motor coupled to the drive wheel and responsive to a control signal from the controller circuit to selectively turn the drive wheel to move the apparatus relative to the substrate.

15. The apparatus of claim 9 ,

wherein the controller circuit is configured to selectively control a position and rotation of the cutting blade relative to the substrate to carve the workpiece into a plurality of portions.
