A scribble machine is a “vibrobot” (vibrating bot) with “legs” than make marks. This project describes one popular scribble machine design, but feel free to make yours with any materials in any shape or size.

Scribble machines work best on a large surface, so break out that big roll of paper and get marking! To avoid scribbling on everything, limit your machine’s range by surrounding it with a 2″+ wall of cardboard, or wood 2″x4″s.


Most scribble machines use pens, but any mark-making tool will work. Try chalk on cement, whiteboard markers on plastic, watercolors on paper… you can even make anti-scribble machines with erasers!

Thanks to The Tinkering Studio at the Exploratorium for introducing me, along with countless others, to scribble machines.
