Artistic Robots

Deussen & Lindemeier's eDavid

A couple of years ago a video started spreading that showed an articulated robotic arm painting intricate portraits and landscapes. This robot was named eDavid and was the work of Oliver Deussen and David Lindemeier from the University of Konstanz. While many painting robots had proceeded eDavid, none painted with its delicacy or captured the imagination of such a wide audience. 

While the robot had remarkable precision it also seemed to have an artistic, almost impressionistic sensibility. So how did it go about creating its art?

When speaking of eDavid's, Deussen and Lindemeier see its paintings as more of a science than art. Their hypothesis is that "painting can be seen as an optimization process in which color is manually distributed on a canvas until one is able to recognize the content. - regardless if it is a representational painting or not." While humans handle this intuitively with a variety of processes that depend on the medium and its limitations, eDavid uses an "optimization process to find out to what extent human processes can be formulated using algorithms."

One of the processes they have nearly perfected is called feedback loops, a concept I use with my own robots and first heard about from painter Paul Klee. It is where you make a couple strokes, take a step back and look at them, adjustment your approach depending on how well those strokes accomplished your intent, then make more strokes based on the adjustment.  You do this over and over again until you finish a painting. Simple concept right? And almost mechanical, but it is how many artists paint.

So to emphasize how well the robot has become at painting with feedback loops, I leave you with my favorite eDavid creation.  Not sure what its title is, but how can you deny that the painting below looks and feels like it was painted by a skilled artist.

Mathew Stein's PumaPaint

I recently spoke with Mathew Stein about his painting robot PumaPaint. Way back in 1998 he equipped a Puma robotic arm with a brush, aimed a web-cam at it, and then invited the internet to crowdsource paintings with it. And he did all this before even crowdsourcing was even a word. In the first two years of the project alone over 25,000 unique users created 500 paintings. The robot continued creating crowdsourced painting for about 10 years.

I asked Mathew if he realized how ahead of its time his PumaPaint Project was.  He laughed and said he had not realized it until the New York Times wrote an article about him.

Oddly enough though, Mathew Stein, does not seam to consider himself an artist, or even realize that his project was an interactive performance art piece. For him it was about the technology and interaction with people around the world. Successful exhibitions in today's art scene are all about audience interaction and experimentation with new media. Without even setting out to do so, Mathew Steins' PumaPaint achieved both on a global scale.  People from around the world were able to use the newly emerging internet to control a teleoperated robotic arm and paint with each other. This would be a cool interactive exhibit by today's standards, and it was done 20 years ago.

Below are some examples of the crowdsourced art produced by PumaPaint. Mathew Stein considers the painting on the right from 2005 to be the single "most interesting piece from PumaPaint."

Whether or not Mathew Stein realizes he is an artist, I do. And much of my own robotic art has been inspired by his early work.
