Hugging Face Unveils $399 Open-Source Bipedal Robot Microduck

Episode 1 · Hugging Face and Pollen Robotics Launch $399 Open-Source Bipedal Robot Microduck (2026-08-27, 65 posts)

On August 27, Hugging Face co-founder Thom Wolf and Pollen Robotics launched Microduck, a $399 open-source bipedal robot, with preorders opening the same day and shipping expected before Christmas 2026. Positioned as the first truly accessible reinforcement learning robot, its full hardware and software stack is Apache-2.0 licensed, dramatically lowering the cost barrier for bipedal robotics research. Demand exceeded expectations, with a Pollen engineer on Reddit reporting one unit sold every 5 seconds on average.

Confirmed

• Microduck is a 25 cm (about 10-inch) tall, sub-800g open-source bipedal robot with 15 actuators and multiple sensors (camera, microphone, speaker, ToF LiDAR, IMU, NFC, Bluetooth, WiFi), featuring an openable "duck bill" and roller skates on its feet
• A collaboration between Pollen Robotics and Hugging Face (tomaarsen noted the announcement by HF CEO Clem), priced at $399, preorders opened August 27 with delivery before Christmas 2026; the official page contains an easter egg (m17)
• It centers on a Sim2Real reinforcement learning workflow with local or remote training, one-click deployment to the real robot, and an open-source SDK
• Works out of the box with multiple pretrained policies (Thom Wolf says 10+; rohanpaulai cites 7), demonstrating walking, sitting, grasping with its bill, self-recovery from falls, roller skating, and even singing
• Per LKama07 relaying a Pollen engineer on Reddit, preorders averaged one unit every 5 seconds, far exceeding expectations; the Reddit community also noted unexpectedly good simulation quality

Why it matters

• Many commenters (tomaarsen, mishig25, reachvb, Hesamation, Terminator857, etc.) view it as the first truly accessible open-source RL robot, making bipedal robotics affordable for individuals; some call it "the Raspberry Pi of the AI era," and DeryaTR relayed the view that it is "the ChatGPT moment for robotics"
• Combining open hardware with a Sim2Real training pipeline, it aims to democratize physical AI and world-model research; rohanpaulai notes it marks Hugging Face's expansion from its model hub business into open-source robotic hardware
• The preorder pace (one unit every 5 seconds) signals that community demand for low-cost open-source real-robot platforms far exceeds expectations
