The Fraunhofer Institute shows off a robot at CeBIT that could take a digital photo and convert it into a drawing. Its day job is measuring the performance of reflective materials.
Fraunhofer's portrait-drawing robot
The Fraunhofer Institute usually uses this robot for gauging the quality of new reflective materials, but at the CeBIT show in Hanover, Germany, it used it to draw portraits. The robot took a digital photo of a person, processed it digitally, drew a line-art portrait, showed it off, erased it, then started over again.
