Product Description

Interact with Otto & Control Your Robot with Modules

The Otto Expansion Builder Kit includes all the 3D printed plastic parts. Just open the box and start building right away. 

Expand your robot's capabilities with the Expansion kit INTERACT. Add tactile reactions through a series of input modules that allow for a myriad of playful activities. Turn your robot into an interactive friend that responds to its environment and promotes STEM+ A learning.

  • Push Button: Execute quick commands effortlessly with the push of a button.
  • Rotational Knob: Adjust brightness, speed levels, and more for precise control.
  • Step Rotation Input: Fine-tune multiple variables and codes with precise step rotation.
  • Proper Acceleration Measurement: Measure your robot's acceleration to create diverse reactions and engaging games.

Remember that each Expansion kit is designed to work only when used with the Starter kit. Use of the Starter kit is therefore required.

The Starter kit is not included in the Expansion kit packaging.

Group use: Up to 2
