Two CD-ROM drives combined into fledging drawbot
July 26th, 2018—
Even if you don’t have access to fancy tools like a 3D printer or CNC router, that doesn’t mean you can’t make something interesting. James, using only a “hot glue gun, some scissors, and a screwdriver,” was able to construct a rudimentary drawing robot that marks paper with a sharpie.
Two CD drives were creatively modified to form X, Y, and Z axes, letting him lower his writing instrument and draw. An Arduino Uno along with an Adafruit Motor Shield forms the controls for the device, and the structure is built out of LEGO bricks.
As of now it’s described as more of an “Etch A Sketch type thing,” but it looks like a great starting point for more advanced drawbots in the future! Code for the build is available on GitHub.
