Who is Otto?

An interactive robot that anyone can make!
Otto walks, dances, makes sounds and avoids obstacles.

Is completely open source, Arduino compatible, 3D printable, and with a social impact mission to create an inclusive environment for all kids.

Otto was inspired by another robot BoB the BiPed and programmed using code from another open source biped robot Zowi.


Otto's differences are in the assembled size (11cm x 7cm x12cm), cleaner integration of components and expressions. Using off the shelf and 3D printed parts, simple electronics connections (almost no welding required), and basic coding skills, you will be able to build your own cute Otto friend in as little as two hours!

Otto is design using Autodesk 123D Design software you can modify it for customization or further improvements!

Gather all the off the shelf parts that you'll need for this assembly.

List of parts:

Arduino Nano, preferable with the pins already weld it
Arduino Nano Shield I/O Extension Board Expansion XD-212
Mini usb cable. (most Arduino dealers provide the cable)
HC-06 Bluetooth Board Module (4-Pin)
HC-SR04 Ultrasound sensor.
Mini servo SG90 9g x6 (each one should come with 2 pointed screws and one small screw).
5V Buzzer.
Female to Female breadboard connectors cable 10cm x 10.
4 AA (6V) Battery case
1.5V AA batteries x4.
Mini cross screwdriver. important magnetized
And then you only need to 3D print 8 parts in total:

3D printed head.
3D printed body.
3D printed left arm.
3D printed right arm.
3D printed left leg.
3D printed right leg.
3D printed left foot.
3D printed right foot.

For the programming:

Download & Install Arduino IDE:
Copy Oscillator libraries to C:\Users\user\Documents\Arduino\libraries (or wherever your library folder is installed):
Finally open & upload OTTO_smooth_criminal.ino code to your Arduino Nano for dancing Otto.

Doesn't Matter








Recommended to use a FDM 3D printer with PLA material. You can print individually piece by piece to match the colors of the original design or optionally print all at the same time.

Hi, have u a github with ino file including arms ? and have u a connects schemes ?

Thanks !

Hi Jason you have one of the coolest remix of Otto DIY feel free to join the group of Otto builders and add your thing thingiverse.com/groups/ottodiy/

Have joined, thank you for your invitation.

Hello, my son chose your robot as his first diy robot. The arms are a great add to a great robot. We have all the parts but the switch. Which switch did you use?

Hi, Thanks for your comment, I use simple switch for that, I have a photo for your refence http://www.jasonworkshop.com/2016/09/20160904.html?m=1
Enjoy your robot!

Hello, have you a scheme to see where the arms connect? thank you! Nice Job!!!

I connected arms to pin6 and pin7, then you need to modify the firmware, if you are a maker, you should be know the fun of DIY.

im very new with arduino so... i have made the arm version... just i have no idea how to get the arm moving at all... now my otto just move around with the arm not moving...

Great Job, so is considered as remix of Otto? http://www.thingiverse.com/thing:1568652

Otto DIY build your own robot

Yes, Thank you for your excellent design ^_^

your video is great i have seen other arms but in other direction to execute punches
