Control a Reachy Mini robot (by Pollen Robotics / Hugging Face) via its REST API and SSH. Use for any request involving the Reachy Mini robot — moving the head, body, or antennas; playing emotions or dances; capturing camera snapshots; adjusting volume; managing apps; checking robot status; or any physical robot interaction. The robot has a 6-DoF head, 360° body rotation, two animated antennas, a wide-angle camera (with non-disruptive WebRTC snapshot), 4-mic array, and speaker.

Reachy Mini Robot Control

Quick Start

Use the CLI script or

curl

to control the robot. The script lives at:

~/clawd/skills/reachy-mini/scripts/reachy.sh

Set the robot IP via

REACHY_HOST

env var or

--host

flag. Default:

192.168.8.17

Common Commands

reachy.sh status                    # Daemon status, version, IP
reachy.sh state                     # Full robot state
reachy.sh wake-up                   # Wake the robot
reachy.sh sleep                     # Put to sleep
reachy.sh snap                      # Camera snapshot → /tmp/reachy_snap.jpg
reachy.sh snap /path/to/photo.jpg   # Snapshot to custom path
reachy.sh play-emotion cheerful1    # Play an emotion
reachy.sh play-dance groovy_sway_and_roll  # Play a dance
reachy.sh goto --head 0.2,0,0 --duration 1.5  # Nod down
reachy.sh volume-set 70             # Set speaker volume
reachy.sh emotions                  # List all emotions
reachy.sh dances                    # List all dances

Environment

Variable	Default	Description
`REACHY_HOST`	`192.168.8.17`	Robot IP address
`REACHY_PORT`	`8000`	REST API port
`REACHY_SSH_USER`	`pollen`	SSH username (for `snap` command)
`REACHY_SSH_PASS`	`root`	SSH password (for `snap` command, uses `sshpass` )

Movement Guide

Head Control (6 DoF)

The head accepts pitch, yaw, roll in radians:

Pitch (look up/down): -0.5 (up) to 0.5 (down)
Yaw (look left/right): -0.8 (right) to 0.8 (left)
Roll (tilt sideways): -0.5 to 0.5

# Look up
reachy.sh goto --head -0.3,0,0 --duration 1.0

# Look left
reachy.sh goto --head 0,0.4,0 --duration 1.0

# Tilt head right, look slightly up
reachy.sh goto --head -0.1,0,-0.3 --duration 1.5

# Return to neutral
reachy.sh goto --head 0,0,0 --duration 1.0

Body Rotation (360°)

Body yaw in radians. 0 = forward, positive = left, negative = right.

reachy.sh goto --body 1.57 --duration 2.0   # Turn 90° left
reachy.sh goto --body -1.57 --duration 2.0  # Turn 90° right
reachy.sh goto --body 0 --duration 2.0      # Face forward

Antennas

Two antennas [left, right] in radians. Range ~-0.5 to 0.5.

reachy.sh goto --antennas 0.4,0.4 --duration 0.5    # Both up
reachy.sh goto --antennas -0.3,-0.3 --duration 0.5   # Both down
reachy.sh goto --antennas 0.4,-0.4 --duration 0.5    # Asymmetric

Combined Movements

# Look left and turn body left with antennas up
reachy.sh goto --head 0,0.3,0 --body 0.5 --antennas 0.4,0.4 --duration 2.0

Interpolation Modes

Emotions & Dances

Playing Emotions

80+ pre-recorded expressive animations. Select contextually appropriate ones:

reachy.sh play-emotion curious1       # Curious look
reachy.sh play-emotion cheerful1      # Happy expression
reachy.sh play-emotion surprised1     # Surprise reaction
reachy.sh play-emotion thoughtful1    # Thinking pose
reachy.sh play-emotion welcoming1     # Greeting gesture

to see all available moves.

Motor Modes

Before movement, motors must be

enabled

. Check with

reachy.sh motors

reachy.sh motors-enable     # Enable (needed for movement commands)
reachy.sh motors-disable    # Disable (robot goes limp)
reachy.sh motors-gravity    # Gravity compensation (manually pose the robot)

Volume Control

reachy.sh volume            # Current speaker volume
reachy.sh volume-set 50     # Set speaker to 50%
reachy.sh volume-test       # Play test sound
reachy.sh mic-volume        # Microphone level
reachy.sh mic-volume-set 80 # Set microphone to 80%

App Management

Reachy Mini runs HuggingFace Space apps. Manage them via:

reachy.sh apps              # List all available apps
reachy.sh apps-installed    # Installed apps only
reachy.sh app-status        # What's running now
reachy.sh app-start NAME    # Start an app
reachy.sh app-stop          # Stop current app

Important: Only one app runs at a time. Starting a new app stops the current one. Apps may take exclusive control of the robot — stop the running app before sending manual movement commands if the robot doesn't respond.

Camera Snapshots

Capture JPEG photos from the robot's camera (IMX708 wide-angle) via WebRTC — non-disruptive to the running daemon.

reachy.sh snap                        # Save to /tmp/reachy_snap.jpg
reachy.sh snap /path/to/output.jpg    # Custom output path

Requirements: SSH access to the robot (uses

sshpass

REACHY_SSH_PASS

env var, default:

root

How it works: Connects to the daemon's WebRTC signalling server (port 8443) using GStreamer's

webrtcsrc

plugin on the robot, captures one H264-decoded frame, and saves as JPEG. No daemon restart, no motor disruption.

Note: The robot must be awake (head up) for a useful image. If asleep, the camera faces into the body. Run

reachy.sh wake-up

first.

Audio Sensing

reachy.sh doa               # Direction of Arrival from mic array

Returns angle in radians (0=left, π/2=front, π=right) and speech detection boolean.

Contextual Reactions (Clawdbot Integration)

Use

reachy-react.sh

to trigger contextual robot behaviors from heartbeats, cron jobs, or session responses.

~/clawd/skills/reachy-mini/scripts/reachy-react.sh

Reactions

reachy-react.sh ack           # Nod acknowledgment (received a request)
reachy-react.sh success       # Cheerful emotion (task done)
reachy-react.sh alert         # Surprised + antennas up (urgent email, alert)
reachy-react.sh remind        # Welcoming/curious (meeting reminder, to-do)
reachy-react.sh idle          # Subtle animation (heartbeat presence)
reachy-react.sh morning       # Wake up + greeting (morning briefing)
reachy-react.sh goodnight     # Sleepy emotion + sleep (night mode)
reachy-react.sh patrol        # Camera snapshot, prints image path
reachy-react.sh doa-track     # Turn head toward detected sound source
reachy-react.sh celebrate     # Random dance (fun moments)

Pass

--bg

to run in background (non-blocking).

Built-in Behaviors

Quiet hours (22:00–06:29 ET): All reactions except
```
morning
```
,
```
goodnight
```
, and
```
patrol
```
are silently skipped.
Auto-wake: Reactions ensure the robot is awake before acting (starts daemon + wakes if needed).
Fault-tolerant: If robot is unreachable, reactions exit cleanly without errors.

Integration Points

Trigger	Reaction	Notes
Morning briefing cron (6:30 AM)	`morning`	Robot wakes up and greets
Goodnight cron (10:00 PM)	`goodnight`	Robot plays sleepy emotion, goes to sleep
Heartbeat (periodic)	`idle`	Subtle head tilt, antenna wave, or look-around
Heartbeat (~1 in 4)	`doa-track`	Checks for nearby speech, turns toward it
Heartbeat (~1 in 6)	`patrol`	Camera snapshot for room awareness
Important unread email	`alert`	Antennas up + surprised emotion
Meeting <2h away	`remind`	Welcoming/curious emotion
Request from Alexander	`ack`	Quick head nod
Task completed	`success`	Random cheerful/happy emotion
Good news or celebration	`celebrate`	Random dance move

DOA (Direction of Arrival) Tracking

The

doa-track

reaction uses the robot's 4-mic array to detect speech direction and turn the head toward the speaker. The DOA angle (0=left, π/2=front, π=right) is mapped to head yaw. Only triggers when speech is actively detected.

Camera Patrol

The

patrol

reaction captures a snapshot and prints the image path. Use this during heartbeats to check the room periodically. Combine with image analysis to detect activity or changes.

Direct API Access

For anything not covered by the CLI, use

curl

or the

raw

command:

# Via raw command
reachy.sh raw GET /api/state/full
reachy.sh raw POST /api/move/goto '{"duration":1.0,"head_pose":{"pitch":0.2,"yaw":0,"roll":0}}'

# Via curl directly
curl -s http://192.168.8.17:8000/api/state/full | jq
curl -s -X POST -H "Content-Type: application/json" \
  -d '{"duration":1.5,"head_pose":{"pitch":0,"yaw":0.3,"roll":0}}' \
  http://192.168.8.17:8000/api/move/goto

Troubleshooting

Robot doesn't move: Check

reachy.sh motors

— must be

enabled

. Run

reachy.sh motors-enable

No response: Check
```
reachy.sh status
```
. State should be
```
running
```
. If not, run
```
reachy.sh reboot-daemon
```
.
Movements ignored: An app may have exclusive control. Run
```
reachy.sh app-stop
```
first.
Network unreachable: Verify the robot IP with
```
ping $REACHY_HOST
```
. Check
```
reachy.sh wifi-status
```
.
Snap shows black image: Robot is likely asleep (head down). Run
```
reachy.sh wake-up
```
first.
Snap fails with SSH error: Ensure
```
sshpass
```
is installed and
```
REACHY_SSH_PASS
```
is set correctly.
