Mug-O-Matic: A Modular Tiny CNC Drawing Robot



COMING TO KICKSTARTER Nov 1st 2018! (Click here to follow!)

 The Mug-O-Matic is a one of a kind DIY toy! A Tiny CNC Drawing Robot that can customize coffee mugs!

This bot can draw anything you want via manual controls, calculated algorithms, or even g-code. Mugs can be washed clean or the drawing can be made permanent by baking it in the oven.

The intent of the project is to produce a fun and accessible educational tool. One that encourages young folks to engage in tinkering and making things because those activities are powerful ways to learn and inspire people to pursue STEM careers.

To that end these robots are very hackable. They are entirely open source and offer an opportunity to play with Arduino, the most common and universally applicable hardware for physical computing. No soldering or bread-boarding required, controls are all plug-&-play. Robots can be assembled with nothing but a screwdriver and enthusiasm! (And the screwdriver is included in kit! 🙂 )

What makes this bot special is that it is designed to perform meaningful specific work as real robots do, rather than exist for ornamental sake. These are real mini-CNC tools in a fun package that allow you to make your own custom creations! What will you make?!

Interested to get your hands on one? Let me know, your support is valued!

To keep my offering simple, I’ve separated this section out a bit.  Much like transformers, there is a lot more than meets the eye to these little bots… 🙂

This open source project is currently in the running for the 2018 HackaDay Prize, so you can read all about its history and current development here.

From my research into the highly recommended book Invent to Learn​, kids learn by doing and are most engaged when they are able to independently experiment rather than just being told what to do. To that end, all components are modular so the parts can be rearranged to build lots of different things to facilitate experimentation!

The Mug-O-Matic is actually just one possible configuration from the Tiny_CNC__Collection. This means inspired students can mix, match, and build their own custom real robots!

License& License Intent:

-The assembled Mug-O-Matic toy robot will be for sale on and I do not want to create competition over sales of my own body of work. You may use the files to build a complete Mug-O-Matic for yourself, but you may not sell them.

-However. The software, the PCB design, and the 3d models of sub-assembly modules & individual components (linear actuator, pivot joint, brackets, etc) are free for you to use however you wish! Source files are provided!

Recommended Reading Material: 

You don’t have to buy any books to learn arduino. There are lots of free resources & videos online. But if you learn best with a book in hand then these are the go to’s:
