SADbot: the Seasonally Affected Drawing robot

Posted by

SADbot was created for and installed in the window gallery at Eyebeam Art + Technology Center (when it was in the Chelsea neighborhood in NYC), in partnership with Ben Leduc-Mills (with funding through Kickstarter). It used two 18.5” x 13” solar panels to power two stepper motors which allow the control of a pen in two dimensions. SADbot takes input from people walking outside the gallery window through a set of sensors (photocells) up against the inside of the window that can tell how much light they’re getting. SADbot knows if someone is covering up one of the sensors, and will change from random drawing to drawing in the direction of the covered sensor.
