Piccolo CNC Drawing Bot: Budding Robotic Artist (3 pics + video)
This tiny stand-alone robot provides an open-source platform for digital fabrication, on a small scale. Piccolo is powered by an Arduino board, and supports movement along X, Y or Z axes. Simply attach a pen, pencil, brush or possibly even an X-Acto knife as its drawing medium. Piccolo can then access uploaded libraries which allow it to create drawings. Multiple small ‘bots can even be synchronized together to create larger illustrations or paintings.
