AxiDraw: Personal Writing and Drawing Machine

Posted in Robots, and Technology


The AxiDraw is a simple, modern, precise, and versatile pen plotter, capable of writing or drawing on almost any flat surface. It can write with your favorite fountain pens, permanent markers, and other writing implements to handle an endless variety of applications. Its unique design features a writing head that extends beyond the machine, making it possible to draw on objects bigger than the machine itself.

Axidraw is a “personal writing and drawing machine” created by Evil Mad Scientist

Evil Mad Scientist Laboratories have continued their great history of bringing amazing drawing robots to Makers everywhere with the AxiDraw. The AxiDraw joins the EMSL line that includes the always popular Eggbot and WaterColorBot. The AxiDraw is a flat pen-based drawing machine, capable of creating intricate art and even calligraphy.


The basic hardware will look familiar to 3D printing fans out there, with a small servo replacing the Z axis of this machine. Watching the product video, I was stunned by the quality of the drawing from the AxiDraw. This simple design looks like it could be a great starter platform for anyone interested in hacking with a drawing platform; add a cutting blade to make a desktop cutter or a laser diode to make a laser etcher, lots of possibilities.

The AxiDraw is an extremely versatile machine, designed to serve a wide variety of everyday and specialized drawing and writing needs. You can use it for almost any task that might normally be carried out with a handheld pen.



It allows you to use your computer to produce writing that appears to be handmade, complete with the unmistakable appearance of using a real pen (as opposed to an inkjet or laser printer) to address an envelope or sign one’s name. And it does so with precision approaching that of a skilled artist, and — just as importantly — using an arm that never gets tired.
