Replaces ui/index.html (old USB-serial HUD) with a full rosbridge
dashboard. Adds ui/dashboard.{css,js}.
Top bar:
- Robot name + ⚡ SALTYBOT logo
- Live battery % + voltage with fill bar (4S LiPo: 12.0V–16.8V)
- Safety state from /saltybot/safety_zone/status (GREEN/AMBER/RED)
- E-stop state display
- Drive mode display
- ROS uptime counter
- rosbridge WS input + CONNECT button
Panel grid (auto-fill responsive):
- MAP VIEW (#587) — /saltybot/pose/fused liveness dot
- GAMEPAD TELEOP (#598) — /cmd_vel activity indicator
- DIAGNOSTICS (#562) — /diagnostics liveness dot
- EVENT LOG (#576) — /rosout liveness dot
- SETTINGS (#614) — param service (config state, no topic)
- GIMBAL (#551) — /gimbal/state liveness dot
Each card shows: icon, title, issue #, description, topic chips,
and a LIVE/IDLE/OFFLINE status badge updated every second. Cards
open the linked standalone panel in the same tab.
Auto-detect rosbridge:
- Probes: page hostname:9090, localhost:9090, saltybot.local:9090
- Progress dots per candidate (trying/ok/fail)
- Falls back to manual URL entry
- Saves last successful URL to localStorage
Bottom bar:
- ⛔ E-STOP button (latches, publishes zero Twist to /cmd_vel)
Space bar shortcut from dashboard
- RESUME button
- Drive mode switcher: MANUAL / AUTO / FOLLOW / DOCK
(publishes to /saltybot/drive_mode std_msgs/String)
- Session timer (HH:MM:SS since page load)
Info strip: rosbridge URL · msg rate · latency (5s ping via
/rosapi/get_time) · robot IP
