Disney Research Creates a Wheeled Robot That Recreates Tablet Sketches as Giant Beach Drawings

Paul Beardsley of Disney Research Zurich and a team from the Swiss Federal Institute of Technology have teamed up to create a small wheeled robot that drags a rake behind it to create giant sketches on beach sand mapped out via a smartphone or tablet. The robot, which debuted at the Techfest conference in Bombay, India in December 2015, takes around 10 minutes to complete the individual sketches.
