Sylvia Todd, a 12-year-old who happens to have this particular passion for robots, has come up with a robot that she has named as the WaterColorBot. The WaterColorBot happens to resemble a 3D printer from certain angles, and just as its name implies, it is capable of churning out artwork that uses watercolor paint, hence its namesake. It works this way – you hook up the WaterColorBot to your computer via USB, load the RoboPaint software, and the WaterColorBot will then “paint” whatever that you create from the software’s canvas itself. I guess there is no Ctrl-Z to get out of a messy spot here, is there?
