Have you built your own Otto? Or any other robot? 

Here is the space to share your automated Projects and robot remixes! Make sure to use the Project tab to attach 3D print files, electronic wirings and codes including nice picture and videos

3D printing, robotics and programming

When Otto meets a dingbot ( then the result can only be a DingbOtto.
The secondary reason for designing this, other than I have a liking for small crazy robots, is to allow holding a bigger battery pack. My first Otto ran with no problem off an external power feed, even from a powerbank, but could not run off its internal 16340 battery. It would work with 2 servos attached, occasionally with 3, but never with 4. This holds a double 18650 battery shield. I will post a real photo rather than just renderings once I have finished painting the model. At the moment it is just a pile of PLA pieces.

Lee robot now FREE files for you to make your own!

This was the first winner of the Otto inventor program, Lee a robot design by @Ronny Martinez, it was selected by the community among many other great submissions,

Lee robot
Lee robot

Lee is very similar to Otto Humanoid but with the option to turn the head in this way you can verify obstacles around it.


Now the inventor wants to share it with the world!

Layer Height : 0.3mm or less / 

Raft  or Brim: Not required 

Support : Not required
Wall Line Count : 2 / Top Solid : 3 / Bottom Solid : 3
Infill Density : 20%
It takes around 15 hours to print.

Thanks Ronny

Otto Theremin

I suspect I am in a very small minority of people who know what a Theremin is. If you don't, Google it. Theremins are awesome.

Anyway, this is a VERY basic 'Theremin' for any Otto or bot build. Very silly, very funny - the way I like things.

I bet a squillion quid Bill SCHONFELDER wants this for Krob or BORK. All Blockly, just missing the Fritzing which I can put together during the England match.

3D model with code, Parametric customization with OpenSCAD

Ok finally had some extra time to push this topic forward.


Read what is about here. Basically you 3d model with code, which there are also some blockly initiatives for this:

We actually had it Otto 3D modeled here long time ago for the thingiverse customizer

Just look at some examples  @Martinperdeauxdid with OpenSCAD files attached for you to play with and you will get the point of how powerful this is.

the actual 3d printed models
the actual 3d printed models


This is a openscad API that allows to use it on the browser, another member @IrevDev is developing it

You can tinker with it at

It also Enables linking to external scad files so long as they return a plain text.

 Cadhub - Parts page

Start on an openscad customizer UI,


You can url reference to a file on Github

Linking to code on Github like this means that the link will stay up-to-date with the repo as it changes.

My dream is to make a super cool customization script for Otto robot where you can swap parts and change sizes and shapes easily keeping the functional elements and tolerances intact so that you are always sure when you 3d print is gonna work, this will be a a game changer in education, since for students the learning curve will be much more smooth. Like what my robot nation did for small figuring but with Otto technology we can actually make them move!

Welcome any opinions around this project.
