An interactive robot that everyone can make, which can be programmed with Arduino or Blockly software, controlled by an app, and can be expanded.

Otto can walk, dance, make sounds, and avoid obstacles. You can write your own code for it and even customize it. It's completely open-source, compatible with Arduino, and can be 3D-printed. For more details, please visithttps://www.ottodiy.com/

Printing instructions

If you've purchased the Builder kit, you can skip this step. However, if you have the Maker kit, you'll need to 3D print the parts. Fortunately, Otto's design is well-suited for 3D printing, so you won't have any trouble if you follow the standard parameters below:

It is recommended to use an FDM 3D printer.
There's no need for supports or rafts.
Resolution: 0.3mm or 0.2mm, to achieve a better resolution
Fill density: 15%

All parts use a total of about 100 grams, equivalent to 35 meters of regular PLA with a thickness of 1.75 mm. Even with optimized settings, printing a complete set of Otto parts only takes about 5 hours, depending on your printer and slicing software.
