SADbot – Seasonally Affected Drawing Robot

SADbot, or the , is a solar-powered, interactive drawing machine created by Eyebeam artists and former ITP students Dustyn Roberts and Ben Leduc-Mills. In the photo above, two women pause to see a pen doodling across a canvas behind a window. When they touch little circles on the glass, the pen changes direction. SADbot uses an Arduino microcontroller, four photocell sensors, a battery, and two stepper motors to control two cables attached to a pen. The electronics receive power from solar panels on the building’s roof. But not only light powers the installation — it also affects SADbot’s behavior. Because it is solar powered, at night SADbot stops doodling and “goes to sleep.” But when the sun is out, SADbot lets people interact with it and doodles across a large canvas. ”People are only happy when it’s sunny,” says Roberts. “Just like our robot.” SADbot was displayed this summer at New York City’s Eyebeam studio, an artist’s hub dedicated to the convergence of art and technology. SADbot raised $1,175 of its $1,000 goal on Kickstarter. Roberts, who also teaches at NYU’s ITP school included SADbot in her recently published book, titled Making Things Move.
