Robots come in all shapes and sizes, from remote landers on distant planets to assembly arms working hard in auto plants. Of course, the definition is broad and can contain more frivolous entities, too. [smdavee]’s watercoloring ‘bots may not be particularly complex or sentient, but they’re a fun creative build.
The design is akin to that of the BristleBot, with a pager vibration motor allowing the ‘bot to wobble about on unsteady feet. In this case, a keyboard cap is used, with cottontips inserted in the base to act as legs. These are then dipped in watercolor paints, and the attached motor is then switched on to vibrate the ‘bot around the page.
It’s an easy build, and one that would be particularly well-suited to teaching young children basic electronic concepts. Plus, there’s the added fun of getting to make a mess with watercolors, too. If you’ve got a fun art robot hiding away in your garage, be sure to let us know. Video after the break.
I guess this is what you need to do if you don’t have a 2 year old to “draw” pictures for you
Why is this an article?
cuz it’s fun. people may be inspired to do this themselves, maybe with their kids. you clicked, didn’t you? if you don’t like it, cancel your subscription.
I like it!
What a fun, simple idea. My 5 year old daughter is super excited to make some of these tonight.
This makes me so happy to hear! I’ve been developing materials and provocations for these types of simple bots in collaboration with all ages, but especially 3-5 year olds most recently. In my post for this project, you’ll see some of the other materials my preschool, k-12, and adult tinkering students have used. Please share your daughter’s creation(s) if you like! I’d love to see them :)

My kid is too young for this but i’m going to save link hoping it wont dissaper in few years and do it for her too its such a neat fun idea. Please do more :)
I’m making these with my extra motors! What can I build on to them…
Thanks so much for posting this, Lewin! I’m honored by your kind words, and by those of the friendly commentators here. For more information on the build of these particular bots, here’s my Instructables post: https://www.instructables.com/id/Keyboard-Cap-Micro-Watercolor-Bots/
