No robot? No problem.

Try it in simulation

The Reachy Mini SDK ships with a MuJoCo-based simulator. The daemon runs locally and behaves exactly like a real Reachy Mini Lite over USB — apps, audio, and motion all work the same way. You can install Good Morning from the dashboard and watch a simulated robot wobble and speak.

1

Install the SDK with the simulator extra

curl -LsSf https://astral.sh/uv/install.sh | sh
uv venv reachy_mini_env --python 3.12
source reachy_mini_env/bin/activate
uv pip install "reachy-mini[mujoco]"

2

Start the daemon in simulation mode

# Linux / Windows
reachy-mini-daemon --sim

# macOS — MuJoCo's GUI needs the mjpython launcher
mjpython -m reachy_mini.daemon --sim

A 3D window opens showing the simulated robot. Leave it running.

3

Open the Reachy Mini desktop app

It auto-detects the running daemon and connects to the simulator instead of a physical robot. The dashboard shows the same simulated 3D view.
4

Install & start Good Morning

Discover Apps → search good-morning → Install → Start. Your browser opens at localhost:7860; click the button and the simulated robot will speak and move just like the real one.
