After seeing a couple really cool examples of "four degrees of freedom" biped out there, I decided that I would make some cool feet and make the robots a bit more creature-like. Current ideas for cool feet are beasty feet, mech-like feet, rock feet.. you know.

The preceding examples of this type of robot used the pcb as the mounting point for the servos, and I've made a generic baseplate with room for a mini breadboard or your own preferred platform. I've also added a "neck" servo for looking around and ultrasonic sensor for sight. I plan to make a housing and more creature feet for this as there is much potential for customization.

The code I'm using is a derivation of the functions and primitives written for uBipedino (tm) by user Ro-Bot-X on the Let's Make Robots site. It is the part of the robot that is in progress, as I am working to fine tune the ultrasonics.

The link to Ro-bot-X's wonderful creation is here: http://letsmakerobots.com/node/30394

Here is a video with some tips and tricks for assembly:

...and here is a video showing Aduped's first steps!



Print out the plastic pieces and bolt on the servos. I used foam tape to stick the feet on. I drilled out the holes on the servo horns a bit and used 2/56 x 5/16"L hardware to bolt everything on. For electronics I used an Arduino Nano, but there are many examples of PIC biped out on the nets too.

Pls send me the working code- [email protected] Thanks!

Hi i was wondering if u would plz send me ur code for the arduped to my email [email protected], i cant believe how cool ur robot is and i relli wanna make one. I am just getting started with arduino and C programming as i am an electronics technician and am new to programming. Would realli appreciate iit if u could send me the code, would help alot as i can only program sensors and make a servo move soo far. cheers:)

Pls Some body can give me the code. PLS.. im new. in 3D print. and im exploring using arduino but i dont know nothing about :) i can move one servo but i dont know how to start to walk.. pls helpme

One day I shall make this when I have spare servos lying around. Made a mount for a distance sensor for another project that might be useful here: http://www.thingiverse.com/thing:595454

Ultrasonic Distance sensor Servo mount

Great design!
Dunno if it's related to you, but http://handmadecircuits.comhandmadecircuits.com just shows an index?

Hi, Yes, I have handmadecircuits. Will fix links soon once Arduped v2 is up and rolling. I've made a new site at http://citizenscientificworkshop.comcitizenscientificworkshop.com that will host my stuff in the future.

hello, can you upload the feet separatly?


Hi! As in upload just the left or right foot in their own file? "A single foot" ?

yes please, a single foot, because I have a thing O matic and the platform is 100x100mm so I can
´t print the Biped puffyfeet archive




Your robot is lovely. I am also making a robot.
What plastic did you use (ABS/PLA)
amp; what printer?




My Sells Mendel and PLA.

The translucent green ?

Its an opaque green, and yeah, that's PLA

Thanks! I hope to put a few more up soon.
