Sprout (Creator Edition)

Fauna Robotics of New York designed the Sprout to live among people rather than on a factory floor, and the numbers reflect it: 107 cm tall, only 22.7 kg, a soft outer shell, minimised pinch points and compliant motors with limited joint torque. The Creator Edition is documented in a technical report dated 26 January 2026 (arXiv 2601.18963).

The biped has 29 degrees of freedom: six per arm, five per leg, two in the neck and one in each gripper, a simple single-axis design with a rubberised inner face. Computing runs on an NVIDIA Jetson AGX Orin with 64 GB of memory and a 1 TB SSD. Vision comes from a ZED 2i stereo camera and four time-of-flight sensors, supported by a torso IMU and a directional microphone array.

A swappable battery lasts 3 to 3.5 hours according to the maker. The software is a modular autonomy stack with a full SDK plus whole-body teleoperation, which positions the Sprout as a platform for research, development, teaching and creative projects in everyday environments. Lifting capacity and walking speed are not published.

The robot is shipping; orders go through a request form and the price is on request. In the class of lightweight research bipeds the usual reference point is the Unitree G1.
