Lesson 02 – Assembling the OTTO DIY Robot

As part of this lesson we will work towards assembling the OTTO DIY Robot.

The creators of Otto DIY robot have put together a few in-depth tutorials to help you learn more about the OTTO robot including assisting you with building the robot. Check out the learning material here –

  1. Learn how OTTO DIY robot works and what it’s made up of
  2. Build Your Own Robot @ OTTO School
  3. Learn how to design your own robot using 3D modelling and 3D printing software

The rest of the tutorial provides access to some of the older content which we had put together to help you get started with the build of the Otto DIY Robot.


Follow the approach in the video below if you’ve purchased the OTTO DIY kit from www.ottodiy.com.

Follow the approach in this video if you’ve purchased the individual parts from ebay/amazon and have 3d printed the other items yourself.

!!! Very Important !!!!! Calibration of the servos!!!!!!!

  1. Before you embed the Arduino Nano, Arduino Nano Extension board, servos and the other sensors into the 3D printed head/body of the robot please take a few minutes to calibrate the servos.
  2. Calibration of the servos ensures that all of them spin their heads in the same direction, at the same time.
  3. You know you’ve been successful when you are able to see all the servos spinning their heads in the same direction with the same amount of travel each time.
  4. If in doubt, look up the manual and revisit the video below.

Check out the tutorial below to calibrate the sensors before you connect them up to the robot.


Additional Content:  Here’s a few other videos on assembly of the OTTO DIY robot offering a slightly different perspective.

What is OTTO DIY – Otto is completely open source, Arduino compatible, 3D printable robot which you can put together yourself. This is robotics and opensource at it’s best. The robot was designed by Camilloa Parra as a social impact mission to create an inclusive environment for all kids. Learn more about OTTO DIY at www.ottodiy.com.
