Humanoid robots are getting smaller, safer and closer

For decades, humanoid robots have lived behind safety cages in factories or deep inside research labs. Fauna Robotics, a New York-based robotics startup, says that era is ending. 

The company has introduced Sprout, a compact humanoid robot designed from the ground up to operate around people. Instead of adapting an industrial robot for public spaces, Fauna built Sprout specifically for homes, schools, offices, retail spaces and entertainment venues.

"Sprout is a humanoid platform designed from first principles to operate around people," the company said. "This is a new category of robot built for the spaces where we live, work, and play." That philosophy drives nearly every design choice behind Sprout.

ROBOTS LEARN 1,000 TASKS IN ONE DAY FROM A SINGLE DEMO

Fauna Robotics' founders started with a simple idea. If robots are going to become part of daily life, they must move naturally around humans and earn trust through safety and reliability. Most humanoid robots today focus on industrial efficiency or controlled research environments. Fauna is targeting a different reality. Service industries now make up the majority of the global workforce. At the same time, labor shortages continue to grow in healthcare, education, hospitality and eldercare. Sprout is designed to explore how humanoid robots could support those spaces without creating new safety risks or operational headaches.

HUMANOID ROBOT MAKES ARCHITECTURAL HISTORY BY DESIGNING A BUILDING

Standing about 3.5 feet tall, Sprout fits naturally into human spaces instead of towering over them. At roughly 50 pounds, it carries less kinetic energy during movement or contact, which makes close interaction safer by design. Lightweight materials and a soft-touch exterior further reduce risk. The design avoids sharp edges and limits pinch points, allowing the robot to operate near people without safety cages. Quiet motors and smooth movement also reduce noise and help Sprout feel less intimidating in shared spaces.

Rather than complex multi-fingered hands, Sprout uses simple one-degree-of-freedom grippers. This approach lowers weight and improves durability while still supporting practical tasks like object fetching, hand-offs, and basic shared-space interaction. Flexible arms and legs allow the robot to walk, kneel, and crawl. Sprout can also fall and recover without damaging sensitive components. In everyday environments, where conditions are rarely perfect, that resilience matters.

Under the hood, Sprout uses a highly articulated body with 29 degrees of freedom to support smooth movement and expressive gestures. Onboard NVIDIA compute provides the processing power needed for perception, navigation, and human-robot interaction without relying on external systems. A battery that supports several hours of active use makes Sprout practical for research, development, and real-world testing in shared human spaces.

Sprout's expressive face helps it communicate in a way people can quickly understand. Simple facial cues show what the robot is doing and how it is feeling, so you do not need technical knowledge to follow along. The robot can walk, kneel, crawl, and recover from falls, which helps it move naturally in everyday spaces. Because its motors are quiet, and its movements are smooth, Sprout feels less startling and more predictable when it is nearby. Behind the scenes, Sprout supports teleoperation, mapping and navigation. These tools give developers the building blocks to create interactions that feel intuitive and human, not stiff or mechanical.

ELON MUSK TEASES A FUTURE RUN BY ROBOTS

Sprout runs on a modular software system that is built to grow over time. Developers get stable controls along with tools for deployment, monitoring, and data collection, so they can focus on building new ideas instead of managing the robot itself. As new abilities improve, Fauna can add them through software updates rather than redesigning the hardware. This keeps costs down and helps Sprout stay useful longer as technology evolves. Fauna also kept sensing simple. Sprout uses head-mounted RGB-D sensors instead of wrist cameras, which reduces complexity and maintenance. At the same time, it still gives the robot a strong perception for moving and working safely in shared spaces.

Fauna positions Sprout as a developer-first humanoid platform rather than a finished consumer product. It is designed for developers who want to build and test applications on accessible hardware with full SDK access and built-in movement, perception, navigation, and expression. At the same time, enterprises can use Sprout to create next-generation AI applications that operate safely in places like retail, hospitality, and offices. Researchers can also use the platform to study locomotion, manipulation, autonomy, and human-robot interaction without building a robot from scratch. Together, these uses point to real-world deployments across retail and hospitality, consumer and home settings, research and education, and entertainment experiences.

Even if you never plan to build a robot, Sprout signals a shift in how robotics companies think about everyday life. Humanoid robots are no longer being designed only for factories and labs. Companies like Fauna are betting that the future of robotics depends on safety, trust, and natural interaction in human spaces. If successful, platforms like Sprout could lead to robots that assist in classrooms, support hospitality staff, help researchers move faster and create interactive experiences that feel less robotic and more human.

Sprout is not trying to replace workers or flood homes with machines overnight. Instead, Fauna is laying the groundwork for a future where humanoid robots earn their place through careful design and responsible deployment. By prioritizing safety, simplicity, and developer collaboration, Sprout represents a quieter but potentially more meaningful step forward in humanoid robotics. The real test will be how developers and researchers use the platform and whether people feel comfortable sharing space with robots like Sprout.
