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 <noreply@anthropic.com>
