reachy-mini-cli

Agent and CLI for operating the Reachy Mini expressive robot — device setup, app management, and live runtime ops.

# Real mode (local robot: daemon binary + SDK):
uv tool install 'reachy-mini-cli[daemon]'
reachy-mini-cli quickstart      # copy-paste install + bring-up sequence
reachy-mini-cli daemon start    # bring the daemon up (wakes the robot)
reachy-mini-cli listen run      # orient the head toward sound (Ctrl-C to stop)

The installed command is reachy-mini-cli (short alias: reachy). New here? Read the Operating Reachy Mini guide — it covers bring-up, verification, and the one model you must understand before running two behaviors at once.

What Reachy Mini can do

Reachy Mini is an expressive desk robot — a movable head, two antennas, a rotating body, a USB mic array (with direction-of-arrival), a camera, and a speaker. reachy-mini-cli exposes each capability as a noun you run from a shell or an agent loop: hold the hardware (daemon), feel alive when idle (demo-mode), orient to sound (listen) or sight (vision), speak (say), think out loud and move in step with its thoughts (think), feel a head pat (pat), and fall asleep when left alone (sleep). listen run --live folds every live sense into one loop, and service makes one presence mode survive a reboot.

Noun map

The complete robot surface. Every noun supports --json; run reachy-mini-cli explain <noun> for the full flag reference.

Noun	What it does	Transport
daemon	Start/stop/status the local reachy-mini-daemon process	none (manages the process)
device	Daemon + live robot state (status, state)	http (default)
app	List / start / stop daemon apps	http
move	One-shot goto / wake / sleep animations	http (default)
demo-mode	Always-on "feel alive" idle loop (breathe, glances, sway)	sdk/http
behavior	50 Hz engine that composes named behaviors per channel	sdk/http
listen	Two-tier sound orienting (antenna lean → head/body turn); --live folds every sense into one loop	sdk default
vision	Turn toward motion or light (pure pixel math, no ML)	sdk default
say	Dumb TTS pipe: text → speaker	sdk default
think	LLM cognition loop: speaks + expresses; --export JSONL feed	sdk default
pat	Feel a head pat and lean into it (no touch sensor)	sdk only
sleep	Decay to sleep when idle; wake on sound / wake-word / pat	sdk default
service	Boot-persist exactly one presence mode (demo or live) via systemd --user	none (manages systemd)
whoami quickstart learn explain overview doctor cli	Agent-first introspection — no robot needed	—

⚠️ Before you run two behaviors at once, read the single-SDK-owner model. The robot serves one in-process SDK client and one motion queue, each a single resource: listen, think, sleep, vision, and pat are mutually exclusive on the sdk transport. This trips up humans and agents repeatedly. The conflict matrix and the two ways to compose behaviors anyway are in the guide.

Install

Profile	Install	For
Real mode (recommended)	uv tool install 'reachy-mini-cli[daemon]'	A local robot — pulls reachy-mini, so the sdk transport and daemon start work out of the box.
HTTP remote	pip install reachy-mini-cli	No local robot — numpy-only; talk to a daemon elsewhere with --transport http + REACHY_BASE_URL.

reachy-mini is an extra, not a base dep (its pycairo/gstreamer/pyaudio stack needs system libraries a bare box lacks). Running the sdk transport on a bare install exits 2 with a hint to install [sdk] — never a traceback. See Install profiles for the full rationale. reachy-cli remains a transitional alias that pulls in reachy-mini-cli.

Operating Reachy live

The full operating guide is docs/operating-reachy.md:

• Bring Reachy up live — install → daemon → verify → behavior
• The single-SDK-owner model — the conflict matrix + how to compose behaviors
• Transports — sdk vs http
• Boot persistence — make one presence (demo/live) survive a reboot via service
• Verify it's working
• The ~/.asoundrc mic-array gotcha — the most common silent failure
• Environment variables — every REACHY_* var in one table
• Troubleshooting — symptoms → fixes, exit codes
• Noun reference — each noun's sense, motion, and transport

Common commands

reachy-mini-cli daemon start                                   # bring the daemon up (wakes the robot)
reachy-mini-cli device status                                  # verify it answers
reachy-mini-cli move goto --z 10 --pitch -5 --duration 2       # one motion command
reachy-mini-cli demo-mode start                                # feel-alive idle loop (background)
reachy-mini-cli listen run                                     # orient to sound (sdk; Ctrl-C to stop)
reachy-mini-cli vision run                                     # orient to motion/light (sdk)
reachy-mini-cli say run "Hello from Reachy"                    # text-to-speech
reachy-mini-cli think run                                      # LLM cognition loop (speaks + moves)
reachy-mini-cli pat run                                        # feel a head pat and lean in
reachy-mini-cli sleep run                                      # fall asleep when idle, wake when addressed
reachy-mini-cli listen run --live                              # ALL senses in one loop (the "live presence" mode)
reachy-mini-cli daemon stop                                    # put it back down

The background nouns (demo-mode, listen, think, sleep) also expose start / stop / restart / status; the sense nouns also expose demo (no robot needed). See reachy-mini-cli explain <noun>.

The live loop and boot persistence

listen run --live folds think + vision + sleep into listen's single loop (alongside the head-pat hook), so every live sense rides one SDK media session and one motion queue in one process — arbitrated by the sleep > pat > think priority flags. It is the supported way to run all the senses at once (one media owner; see the single-SDK-owner model below).

Add --transcribe and live cognition hears words: nearby speech is transcribed via the external STT service (model-gear / Parakeet at REACHY_STT_URL, default localhost:9002) and the recognised words flow into the think loop, so the robot reasons about what was said — not just that a sound came from the left. Off by default (the live loop is unchanged when off); --transcribe requires --live and the sdk transport. A self-mute window means the robot never transcribes its own voice, and an unreachable STT degrades to "no words" rather than stalling the loop. It is not a chat/turn-taking assistant — words are one more perception. The deployed live boot service runs with --transcribe on, so the on-robot presence hears words out of the box.

reachy-mini-cli listen run --live --transcribe                 # hear words + react to them

service makes one presence boot-persistent via systemd --user. Exactly one mode is enabled at a time — enabling one disables the sibling — and it auto-restarts on crash. The daemon is a boot dependency of both presence units.

reachy-mini-cli service install                                # write the systemd units (enable nothing)
reachy-mini-cli service enable live                            # boot-persist listen run --live (disables demo)
reachy-mini-cli service enable demo                            # switch to the idle demo loop (disables live)
reachy-mini-cli service status --json                          # which mode is enabled + daemon health
reachy-mini-cli service disable                                # stop the presence (daemon stays up)

A true machine-reboot check is manual: a systemctl --user service starts at boot only when the user has linger enabled (loginctl enable-linger $USER). See Boot persistence.

Export feed

think run --export - streams a live newline-delimited JSON (NDJSON) feed of what the robot is thinking / saying / feeling — one object per line. The renderer stays out of this repo by design (the export decoupling boundary): reachy-mini-cli emits a documented contract, a separate consumer renders it.

reachy-mini-cli think run --export -                              # all block types
reachy-mini-cli think run --export - --export-blocks message,emotion
reachy-mini-cli think run --export - | <your renderer>

Wire format: docs/export-schema.md. For the renderer boundary and the reference reterminal consumer, see Export feed & the external renderer.

What you get

• An agent-first CLI cited from teken (afi-cli).
• A mesh identity — culture.yaml (suffix + backend) and the matching prompt file (CLAUDE.md for backend: claude).
• The canonical guildmaster skill kit (11 skills) under .claude/skills/, vendored cite-don't-import. See docs/skill-sources.md.
• A build + deploy baseline — pytest, lint, the agent-first rubric gate, and PyPI Trusted Publishing wired into GitHub Actions.

Developer quickstart

For working on the repo itself (an editable checkout, not an end-user install):

uv sync --extra daemon                # recommended — SDK + the reachy-mini-daemon binary
uv sync                               # bare — numpy only; HTTP remote profile (--transport http)
uv run pytest -n auto                 # run the test suite
uv run reachy whoami                  # identity from culture.yaml
uv run reachy learn                   # self-teaching prompt (add --json)
uv run teken cli doctor . --strict    # the agent-first rubric gate CI runs

CLI (introspection)

The agent-first verbs that work with no robot attached:

Verb	What it does
whoami	Report this agent's nick, version, backend, model from culture.yaml.
quickstart	Print the copy-paste install + bring-up sequence.
learn	Print a structured self-teaching prompt.
explain <path>	Markdown docs for any noun/verb path.
overview	Read-only descriptive snapshot of the agent.
doctor	Check the agent-identity invariants (prompt-file-present, backend-consistency).
cli overview	Describe the CLI surface itself.

Every command supports --json. Results go to stdout, errors/diagnostics to stderr (never mixed). Exit codes: 0 success, 1 user error, 2 environment error, 3+ reserved.

Make it your own

1. Rename the package reachy/ and the reachy-mini-cli CLI/dist name throughout pyproject.toml, the package, tests/, and sonar-project.properties.
2. Edit culture.yaml with your suffix and backend.
3. Rewrite CLAUDE.md for your agent and run /init.
4. Re-vendor only the skills you need from guildmaster (see docs/skill-sources.md).

See CLAUDE.md for the full conventions (version-bump-every-PR, the cicd PR lane, deploy setup).
