For instance, a permanent marker, brushes, spray paint, markers, and so on are used. These robots also use a variety of software tools to make the art, including a cool programming language called G-code designed for computers to control motors, usually motors connected to CNC (Computer Numeric Control) routers and 3D printers. However, the technology can also be harnessed to control a mobile robot’s movements. You’ll learn more about G-code later on in this chapter.
Finally, you’ll build the Rolling ‘Riter ...
