Pollen Robotics' $399 Microduck: open-source RL duck, HN's front page

Pollen Robotics, a Bordeaux robotics startup founded in 2016 and acquired by Hugging Face in April 2025, is betting that physical-AI learning belongs on people's desks, not only in well-funded labs. Its Aug 27, 2026 launch of Microduck - a 25 cm, 800 g open-source biped priced at $399 - puts a reinforcement-learning, sim-to-real development platform inside a toy-like duck that waddles, kicks a ball, roller-skates and picks itself up after falling.

The wedge is the price of failure. Training movement policies on real robots usually means expensive hardware and costly repairs; Microduck is cheap enough that a fall is a thud, and its behaviors are RL policies trained in the MuJoCo physics simulator and deployed directly to the robot. Pollen publishes the SDK, the robot software and the full RL training stack on GitHub under Apache-2.0, so retraining and sharing policies works the way sharing open models does.

The launch was an immediate developer-community event: the HN thread reached the front page on Aug 27, 2026 with 781 points and 252 comments, and TechCrunch, The Verge and Digital Trends covered it the same week. Preorders opened at $399 in four colors - cream, graphite, lavender and sky blue - with first deliveries promised before Christmas 2026.

As of Sept 2, 2026 the robot is in preorder, the GitHub repo has 693 forks, and Microduck joins Reachy Mini in Hugging Face's open-hardware line. The unanswered question is whether a cute, programmable robot becomes a mass-market way to learn physical AI - or stays a beloved developer toy.
