Welcome to Otto Builders the community of Otto DIY robot, we share knowledge, solve problems and make all kinds of opensource robots.


Projects that can be added to make Otto starter modular. 

Different from current remixes of Ottos, Some of these could be made available as small expansion/extension boxes to add, physical expansion packs.

Good evening hello everyone....

Otto robot rotating head

Inspired by a video featured in this group, I have finished the extension so that Otto can move his head a little 45, 90 and 135 degrees, I could not achieve more travel, through the connection cables but it is a good start. compatible with version 10 and 11 of Otto body. however I have a rare vibration in the servo. 

I leave the video for you to observe the detail. Thanks. 

I attached the stl files, with the extension. Greetings.

We have spent over a year gathering feedback, testing and creating our greatest product... (More)

Birger T mission accomplished, we have the OLED expansion working and compatible with the previous ones. Bill SCHONFELDER you can also follow this modular approach for the laser, mp3 audio, neopixels other displays and so on.

Compatible with previous versions of Otto starter, plus and eyes. Even uses the same head as wheels.
Following Birger T suggestions here is another expansion having the arms to the front, including a new grip design for you to 3D print. Do you want them for for boxing :D? Note the clip on the back is for the Bluetooth module ;*

Legs you can use Ottoky ones alternatively. they are outside the body without elevating the center of gravity

Next will be the OLED display as alternative to the LED matrix but there are memory limitations for it... how are we gonna solve that?
