Well, I’m wicked proud of this ‘bot. Dig it:
This cute little bristle bot is about 2″ large, costs ~$5 to make, and I’m amazed at how well it zips around my kitchen floor. It’s just two vibrating motors, two toothbrush heads, and a remote control pulled out of another robo-toy. I really want to see a little swarm of these guys with a little bit of intelligence, even if it’s just light-seeking or light-fearing.
I prototyped this guy in four days in hong kong, starting from scratch with my first bristlebot:
Then moving on to an R/C, steerable ‘bot made entirely out of mangled toothbrushes and hot glue
And then moving on up to 3D printed bodies. Square bodies don’t work so well, because the robot can only drive forward and turn, so it gets stuck. My third iteration is the circular ladybugbot
Here’s some video of the ladybugbot being adorable:
So, that’s the ladybugbot. It’s stunningly cheap and fast to build–the motors are fifty cents each, the bodies take about an hour to print out, and my latest and greatest prints come out of the makerbot complete with bristles and snap-mounts for the motors. I’d like to end up with some $5 ‘bots that have some smarts–enough to do basic communication and navigation. The future is coming, and it’s small, round, and pink!
If you like it, make one for yourself! You can use pretty much any vibrating motors you can get your hands on–I’ve been ripping mine out of cheap little vibrating toys, but there’s lots on ebay, in junk stores, and on hobbyist electronics sites like seeedstudios.com
I ripped the electronics out of a deskpet (http://www.mydeskpets.com/) to make my remote controller, and that gave me a cheap remote, motor controller and battery.
The 3D printed files are all up on thingiverse here: http://www.thingiverse.com/thing:12975
And the toothbrushes you can get at your preferred toothbrush retail location. Hold everything together with some dabs of hot glue, and away you go. If you make one or improve on it, let me know–I’d love to see more little pink robots in the world.
