Replica image 21b: first boot and SSH checks
The author fixes fresh-card startup and adds your own SSH key. Full motion acceptance remains unfinished, even though GitHub’s prerelease flag is false.

Substantive guide updates first, including new steps added to older articles.
Understand the October 17 updater fixes, diagnose metadata-size errors and inspect an exact-version dry run before a deliberate daemon upgrade.
Follow an eight-stage Open Duck Mini v2 build route covering parts, printing, servo IDs, assembly, wiring, Raspberry Pi setup, calibration and first walk.
Use a filled six-component Open Duck Mini v2 parts plan, author-listed EUR prices, printing quantities and a checklist for the remaining costs.
Walk in the official MicroDuck browser simulator, load a public policy by URL, check manifest compatibility and restore the built-in move.
Upgrade from 0.17.2 with the October 15 stable releases; inspect the local vet book, claim separate UDP pads and rediscover Beta boards safely.
Current keys, a short exercise and loading help.

Prepare the official MicroDuck RL environment with a pinned revision, Python 3.12, a CUDA check and a short training run before a longer experiment.
Export a MicroDuck checkpoint with observation normalization, select the correct playback input layout and inspect a policy package before sharing.
On an official MicroDuck, use duckctl from a laptop to distinguish Bluetooth discovery, missing Wi-Fi address and console signalling before changing settings.
Run the real MicroDuck daemons against a MuJoCo body, inspect health and motion with robotctl, measure real-time speed, and understand what this setup cannot test.
Check the official v8 velstand policy, update the separate policy set, identify persistent walk overrides, and reset one slot safely.
MicroDuck is a small biped robot introduced by Pollen Robotics for exploring learned body movements. The official project links its robot software, reinforcement learning framework and browser simulator.
Official MicroDuck introduction →MicroDuck Robot Community is an independent technical publication and maker community. It is not affiliated with Pollen Robotics, Hugging Face or emwstudio.
About this community →Begin with the official browser simulator to explore existing movements. Training new movements is a separate activity with its own software and compute requirements.
MicroDuck simulator guide →The DuckEMW results discussed here are author-reported simulation experiments. They are not measurements of physical robot performance verified by this site.
DuckEMW project and source record →A hand pushes the physical MicroDuck; the robot takes corrective steps to regain its balance.
