They say that there’s more to a Jackson Pollock painting than randomly scattering paint on a canvas, and the auction value of his work seems to verify that claim. If you want to create some more conventional artwork, however, but are missing the artistic muse that inspired Pollock, maybe you can put your creative energies to work building a robot that will create the art for you.
[Dane Kouttron] was able to get his hands on an old SCARA robotic arm, and was recently inspired to create a paintbrush-weilding robot with it for the 2nd Annual Robot Art competition. Getting one of these ancient (circa 1983) robots working again is no easy task though. [Dane] used LinuxCNC to help reverse engineer the robot’s controls and had to build a lot of supporting hardware to get the extremely heavy robot to work properly. The entire process took around two months, and everything from color selection to paint refill to the actual painting itself is completely automated.
Be sure to check out the video after the break to see the robot in action. The writeup goes into great detail about the robot, and includes everything from reverse engineering the encoders to auto-cleaning a paintbrush. If you don’t have a SCARA robot arm in your parts drawer, though, there are lots of other options to explore for robot-created artwork.
