Pollen Robotics Opens Preorders for Microduck, a $399 Open-Source Biped Robot
The 25cm robot from the Hugging Face subsidiary has 15 motors and seven trained behaviors. Every policy can be retrained, and the full software stack is Apache 2.0 on GitHub.
Pollen Robotics, part of Hugging Face, opened preorders for its Microduck biped robot on August 27, 2026 1.
- The introductory price is $399 before taxes and shipping, with shipping planned before Christmas 2026. The company describes it as a 25cm open-source biped you train yourself with reinforcement learning 1
- The specifications list 15 motors, a height of 25cm, a camera plus LiDAR and two IMUs, and a 50Hz onboard policy loop. It can pick up objects weighing up to 800g with its beak 1
- Seven trained moves ship in the box, including walking, sitting and standing, kicking, scooping an object up, roller skating, and getting back up after a fall 1
Each behavior is a policy that can be retrained, with training done in physics simulation either on your own machine or on Hugging Face Jobs 1. The SDK, the MuJoCo simulation environment and the full reinforcement learning training stack are on GitHub at pollen-robotics/microduck under Apache 2.0 — meaning a full hardware-plus-software setup for trying reinforcement learning on a real robot starts at $399 1.
