Two-Axis DrawBot

July 11, 2020

Some time back, I worked on a two-axis drawing robot that could draw digital artworks using a pen. See the image below.

I guess a printer could something, but I think there is some kind of authenticity present in art pieces drawn using pens or pencils. I used two stepper motors, one for the x-axis and another for the y-axis, to move a pen and create precise drawings based of coordinated generated from an input image.

The main operating principle was actually fairly simple. We get a simple SVG image, then convert the outlines to coordinates, which will then be used to generate a path connecting each of the points. This path directs the pen’s movement, creating a physical representation of the digital art.
