Fraunhofer: The Artist Sketching Robot


Could robots be replacing artists in the future? A new invention called the Fraunhofer robot could do so.

This industrial robot is able to draw a portrait of a person in as little as ten minutes. First, it looks at its subject with the help of a camera. Then, it takes a pencil to sketch an image of the subject, producing a likely replica of a human-drawn portrait.

To achieve this, the Fraunhofer robot makes use of edge-processing technology. This software tries to analyze the contrasts in a camera image and sends messages to the robotic arm for it to move across paper.

The idea is simple, but the team behind it at Fraunhofer Institute for Optronics, System Technologies and Image Exploitation IOSB have as well encountered some difficulties in its algorithm.

For instance, they had to┬ámodify the directions for the robot for it to ignore small wrinkles on the subject’s face. On the other hand, it had to be sensitive enough to catch the details of the human eye.

The Fraunhofer team, however, sees other uses for the robot than art. In fact, the invention is used for studying the optical reflections of different kinds of materials. With its software, it is able to measure how much a particular material reflects light.
