I think it would be cool to make a robot that consumes a digital image and outputs a watercolor painting, and this project was the first step along that path. At its core, it’s a liquid handling robot that is a lot like those that are commonly used for biotechnology applications. The “canvas” here is a standard medical grade 384 well microplate. Instead of dispensing useful biological or chemical agents into the wells, my robot dispenses water mixed with a bit of CMYK printer dye and surfactant (more on that later). My script takes an image, and the robot re-creates that image by mixing dyes in a microwell plate.
