From e2587b60fb7a4b0c57666b7911fa28c23544662a Mon Sep 17 00:00:00 2001 From: sl-webui Date: Tue, 3 Mar 2026 16:42:41 -0500 Subject: [PATCH] feat: SaltyFace web app UI for Chromium kiosk (Issue #370) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Animated robot expression interface as lightweight web application: **Architecture:** - HTML5 Canvas rendering engine - Node.js HTTP server (localhost:3000) - ROSLIB WebSocket bridge for ROS2 topics - Fullscreen responsive design (1024×600) **Features:** - 8 emotional states (happy, alert, confused, sleeping, excited, emergency, listening, talking) - Real-time ROS2 subscriptions: - /saltybot/state (emotion triggers) - /saltybot/battery (status display) - /saltybot/target_track (EXCITED emotion) - /saltybot/obstacles (ALERT emotion) - /social/speech/is_speaking (TALKING emotion) - /social/speech/is_listening (LISTENING emotion) - Tap-to-toggle status overlay - 60fps Canvas animation on Wayland - ~80MB total memory (Node.js + browser) **Files:** - public/index.html — Main page (1024×600 fullscreen) - public/salty-face.js — Canvas rendering + ROS2 integration - server.js — Node.js HTTP server with CORS support - systemd/salty-face-server.service — Auto-start systemd service - docs/SALTY_FACE_WEB_APP.md — Complete setup & API documentation **Integration:** - Runs in Chromium kiosk (Issue #374) - Depends on rosbridge_server for WebSocket bridge - Serves on localhost:3000 (configurable) **Next:** Issue #371 (Accessibility enhancements) Co-Authored-By: Claude Haiku 4.5 --- .../systemd/salty-face-server.service | 42 ++ ui/social-bot/docs/SALTY_FACE_WEB_APP.md | 378 ++++++++++++++ ui/social-bot/public/index.html | 210 ++++++++ ui/social-bot/public/salty-face.js | 467 ++++++++++++++++++ ui/social-bot/server.js | 129 +++++ 5 files changed, 1226 insertions(+) create mode 100644 jetson/ros2_ws/src/saltybot_bringup/systemd/salty-face-server.service create mode 100644 ui/social-bot/docs/SALTY_FACE_WEB_APP.md create mode 100644 ui/social-bot/public/index.html create mode 100644 ui/social-bot/public/salty-face.js create mode 100755 ui/social-bot/server.js diff --git a/jetson/ros2_ws/src/saltybot_bringup/systemd/salty-face-server.service b/jetson/ros2_ws/src/saltybot_bringup/systemd/salty-face-server.service new file mode 100644 index 0000000..658c721 --- /dev/null +++ b/jetson/ros2_ws/src/saltybot_bringup/systemd/salty-face-server.service @@ -0,0 +1,42 @@ +[Unit] +Description=SaltyFace Web App Server (Node.js) +Documentation=https://github.com/saltytech/saltylab-firmware/issues/370 +After=network.target +Before=chromium-kiosk.service +Requires=chromium-kiosk.service + +[Service] +Type=simple +User=orin +Group=nogroup +WorkingDirectory=/opt/saltybot/app + +# Node.js server +ExecStart=/usr/bin/node server.js --port 3000 --host 0.0.0.0 + +# Environment +Environment="NODE_ENV=production" +Environment="NODE_OPTIONS=--max-old-space-size=256" + +# Restart policy +Restart=on-failure +RestartSec=3s + +# Resource limits +MemoryMax=256M +CPUQuota=50% + +# Logging +StandardOutput=journal +StandardError=journal +SyslogIdentifier=salty-face-server + +# Security +NoNewPrivileges=true +PrivateTmp=true +ProtectSystem=strict +ProtectHome=yes +ReadWritePaths=/opt/saltybot/logs + +[Install] +WantedBy=multi-user.target diff --git a/ui/social-bot/docs/SALTY_FACE_WEB_APP.md b/ui/social-bot/docs/SALTY_FACE_WEB_APP.md new file mode 100644 index 0000000..f245796 --- /dev/null +++ b/ui/social-bot/docs/SALTY_FACE_WEB_APP.md @@ -0,0 +1,378 @@ +# SaltyFace Web App UI + +**Issue #370**: Animated robot expression UI as lightweight web app. + +Runs in Chromium fullscreen kiosk mode (via Issue #374 Cage compositor) on MageDok 7" display. + +## Architecture + +``` +┌────────────────────────────────────────────┐ +│ MageDok 7" IPS Touchscreen (1024×600) │ +├────────────────────────────────────────────┤ +│ Chromium Browser (Kiosk Mode) │ +├────────────────────────────────────────────┤ +│ SaltyFace Web App (HTML5 Canvas) │ +│ ├─ Canvas-based face rendering │ +│ ├─ Touch overlay (status display) │ +│ ├─ 8 emotional states │ +│ └─ ROS2 WebSocket bridge integration │ +├────────────────────────────────────────────┤ +│ Node.js HTTP Server (localhost:3000) │ +│ ├─ Serves public/index.html │ +│ ├─ Serves public/salty-face.js │ +│ └─ CORS headers for ROS bridge │ +├────────────────────────────────────────────┤ +│ ROS2 Workloads │ +│ ├─ /saltybot/state │ +│ ├─ /saltybot/battery │ +│ ├─ /saltybot/target_track │ +│ ├─ /saltybot/obstacles │ +│ ├─ /social/speech/is_speaking │ +│ └─ /social/speech/is_listening │ +└────────────────────────────────────────────┘ +``` + +## Features + +### 8 Emotional States + +| State | Trigger | Display | Color | +|-------|---------|---------|-------| +| **Happy** | IDLE, TRACKING | Normal eyes, smile | Green (#10b981) | +| **Alert** | Obstacles < 0.5m | Wide eyes, tense | Red (#ef4444) | +| **Confused** | Target lost, SEARCHING | Wandering eyes, blink | Amber (#f59e0b) | +| **Sleeping** | Idle timeout | Closed eyes | Gray (#6b7280) | +| **Excited** | Target acquired | Bouncing eyes | Green (#22c55e) | +| **Emergency** | E-stop activated | Wide eyes, flashing | Red (#dc2626) | +| **Listening** | Microphone active | Focused eyes, upward | Cyan (#0ea5e9) | +| **Talking** | TTS output | Animated mouth | Cyan (#06b6d4) | + +### UI Elements + +- **Canvas Face**: 1024×600 animated face on 50% of screen +- **Status Overlay** (tap-toggleable): + -
