A repurposed robot finds a new career in portraiture.
By Alex Hutchinson
An industrial machine has abandoned its day job to become an artist. Researchers at the Centre for Art and Media in Karlsruhe, Germany, have taught a robot normally used to analyse the optical reflection of materials such as car paint or safety vests to render portraits. The robot records an image with its camera, then applies edge-processing software to search for key facial lines. It sketches those in pencil, producing a reasonable likeness in roughly 10 minutes.
