If robots are going to exist around people, they have to be designed differently.
Designed for builders across robotics, AI, academia, entertainment, retail, and hospitality, Sprout brings bipedal mobility, expressive interaction, and manipulation together in a lightweight, durable, and approachable package.
Its 29-DoF body, natural voice interface, and soft, human-centric design make it ideal for deploying robots in the same environments people live and work.
We’ve published our first technical report on Sprout.
Our paper outlines the design choices behind a lightweight, compliant humanoid platform built to operate safely in human environments and the system architecture that makes experimentation possible.

Sprout was designed with safety at its core.
If robots are going to exist closer to people, safety has to shape the entire system. It has to inform the materials we choose and the way our robot moves and responds in shared spaces.
Sprout was built with a safety-first design from the beginning. Its lightweight construction, compliant locomotion, and minimal pinch points are just a few of the many design choices that make Sprout trustworthy to be around.
For builders, researchers, and users of these robots, safety is what makes everything else possible.
What does it feel like to work with a humanoid robot in real environments?
Sprout is built to support long sessions of experimentation, interaction, and iteration in the same spaces people live and work. Its compact, lightweight humanoid form and compliant motion make it comfortable to operate around people, while still supporting full-body movement and manipulation.
With 29 degrees of freedom, integrated sensing, and whole-body control, Sprout enables locomotion, object interaction, and expressive behaviors that can be explored directly through hands-on use.
Developers can step into the robot through full-body VR, guide it through real spaces, and record synchronized motion and perception data along the way. Time spent with the robot turns into insight, data, and new ideas.
What would you try with Sprout?
Yesterday, we introduced Sprout.
Today, we wanted to share the story behind it.
From the beginning, our team focused on a simple question: what would it take for a robot to exist comfortably in human spaces?
Fauna began with a small team and early prototypes, learning by doing and refining what mattered most through real use. Over time, that process shaped how we think about humanoid robots and what it takes for them to leave the lab and operate in the world.
Sprout is the result of that work. A developer platform shaped deliberately, built to grow alongside the people who use it.
If you’re curious where this journey began and where it might lead next, you’re already part of the story.
Meet Sprout.
Today, we’re releasing a new kind of robotics platform. One designed to move out of the lab and into the real world, closer to the people who will shape what robots become next.
It’s built for builders. For people who want a strong foundation without starting from scratch. A robot you can work with, experiment on, and extend, without fighting the basics.
Sprout comes from a simple belief: robots should feel approachable, capable, and safe to be around. That belief has guided every decision we’ve made, step by step, capability by capability.
What will you build with Sprout?
