Microduck is a 25cm, $399 open-source bipedal robot built by Hugging Face and Pollen Robotics. It’s designed for sim-to-real reinforcement learning. It ships with 7 pre-trained behaviors and an Apache 2.0 software stack you can clone, modify, and retrain.
Quite a week for @Hugging Face. Right after the reported big deal, they’re launching something very on-brand with Pollen Robotics: a $399 open-source biped you can train yourself.
It’s desk-sized — 25cm tall, under 800g — and already walks, picks things up, gets back up after a fall, and even roller-skates.
Congrats on launch number twenty. Apache 2.0 on the software stack of a $399 robot is a lot to give away.
the sim-to-real part is what i'd actually want to know more about. training in the browser sim and just dropping it onto the real robot sounds great in a demo but usually there's a gap - does it walk fine on the first try or does it need retraining once it's on actual hardware
Love that you made a real bipedal robot hackable under Apache 2.0, turning sim-to-real RL from a lab luxury into something anyone can retrain on their desk.

Hi everyone!
Reachy Mini has a new little buddy 🦆
Quite a week for @Hugging Face. Right after the reported big deal, they’re launching something very on-brand with Pollen Robotics: a $399 open-source biped you can train yourself.
It’s desk-sized — 25cm tall, under 800g — and already walks, picks things up, gets back up after a fall, and even roller-skates.
You can mess with how it moves in the browser first, then put the new behavior on the real robot.
The whole software stack is open under Apache 2.0.
Reachy is the one you talk to. This one you teach to walk!
