Fauna Robotics
Fauna Robotics is a New York company that built Sprout, a small, friendly humanoid robot for developers, researchers and educators, and was acquired by Amazon in March 2026. It was founded in 2024 by Rob Cochran, its chief executive and formerly of CTRL-labs, and Josh Merel, its chief technology officer and a former DeepMind research scientist. Sprout is about 107 cm tall and 22.7 kg, padded in soft foam, with 29 degrees of freedom including articulated eyebrows, an NVIDIA Jetson AGX Orin computer and a swappable battery that runs for about three to three and a half hours. Its compliant motors and soft exterior are designed so people can safely work around it at home, in schools and in labs. Fauna launched Sprout on 27 January 2026 as a Creator Edition, with early users including Disney, Boston Dynamics, UC San Diego and NYU, and it has been reported at about US$50,000. Fauna raised about US$16.6 million before Amazon acquired it.
π‘Notable Achievement: Fauna Robotics created Sprout, a friendly 3.5-foot humanoid featuring a soft foam exterior and torque-limited compliant joints designed for everyday human spaces, which led to the startup's landmark acquisition by Amazon in March 2026.
What Does Fauna Robotics Do?
Fauna Robotics is solving the humanoid 'deployment gap' by proving that human-scale robots do not need to be heavy, intimidating, or dangerous industrial machines. Founded by roboticists from Harvard and the Salk Institute, Fauna created Sproutβa delightful, lightweight 3.5-foot humanoid wrapped in soft foam and engineered specifically to share living spaces safely with people. Now part of Amazon's robotics ecosystem following its landmark March 2026 acquisition, Fauna Robotics combines approachable mechanical compliance with cutting-edge physical AI, laying the groundwork for safe, everyday household humanoid assistants.

Sprout
Manufactured by Fauna Robotics
Sprout by Fauna Robotics is a compact, lightweight humanoid robot designed for safe human interaction and developer-friendly applications in research, education, and commercial development. Standing at 107 cm tall and weighing 22.7 kg, it features 29 degrees of freedom for full-body articulation, including 6 DoF arms with floor-to-countertop reach, 5 DoF compliant legs for low-impact bipedal locomotion, and a 2 DoF neck for expressive gaze. Equipped with NVIDIA Jetson AGX Orin compute, ZED 2i stereoscopic vision, time-of-flight sensors, IMU, microphone array, and a full-color 360-degree facial LED array with motorized eyebrows, Sprout enables out-of-the-box mapping, navigation, voice interaction, walking, kneeling, crawling, jumping, dancing, and fall recovery. Its soft deformable exterior, back-drivable motors, and dedicated safety subsystem ensure collaborative operation in shared human spaces, while swappable batteries provide 3-3.5 hours runtime and LEGO-compatible customization fosters modular innovation in manipulation, task planning, and human-robot interaction.
