This robot was designed to have human-like focus. It looks first at the subject, then at the paper, and wiggles its little robot arm to make marks with a Bic pen. From this, a portrait is produced.
It’s normal to assume that creative work is an emotional process, but observational drawing is more like this studious robot here. Drawing is look, measure, mark. Look, measure, mark. (Repeat.) It’s a gentle engagement; look, measure, mark, repeat. When I draw, I resemble this robot. This robot that was designed to draw like me.
