NIGEL

Navigation, Incident Guidance, and Emergency Localization & Control — a mission-control style interface for the Future Interfaces hackathon. It turns VSLAM (visual mapping) data and radio-style transcripts into a unified command center.

Think of it as air traffic control, but for firefighters on a floor plan: multiple video feeds, a growing 3D map from the helmet rig, and a radio panel that can drive what you see on the map.

What's in this repo

Path	Role
frontend/	Next.js app: dispatcher dashboard, Three.js point-cloud view, WebSocket feeds, API routes
ros2/	ROS 2 workspace: Odin driver, SLAM cloud accumulator, launch files
features.md	Product / UX spec (panels, semantic radio, stretch goals)

Frontend highlights

• Dispatcher (/dispatcher) — multi-unit viewports, central 3D map, blueprint search, radio / transcript UX
• Firefighter (/firefighter) — field-facing UI
• WebSockets — live SLAM / camera data; see frontend/docs/WEBSOCKET_ARCHITECTURE.md and ros2/src/slam_cloud_accumulator/WEBSOCKET_API.md for architecture details

ROS 2 packages

• odin_ros_driver — depth / point cloud pipeline for Odin hardware (package README)
• slam_cloud_accumulator — accumulates SLAM clouds for streaming to the web stack

Prerequisites

• Node.js 20+ (matches frontend tooling)
• ROS 2 (Jazzy or your team's distro) for the ros2/ workspace
• Optional: TLS certs under frontend/certificates/ for HTTPS dev (otherwise the dev server falls back to HTTP — see frontend/server.js)

Quick start — web UI

cd frontend
npm install
npm run dev          # HTTPS if certs exist, else HTTP on :3000
# or: npm run dev:http   # plain Next dev server

Open http://localhost:3000 or https://localhost:3000 depending on your setup.

More detail: frontend/README.md.

Quick start — ROS 2 (outline)

From the ros2 workspace root (after installing ROS 2 and dependencies):

cd ros2
source /opt/ros/<distro>/setup.bash
colcon build
source install/setup.bash
# Launch files live under ros2/src/odin_ros_driver/launch_ROS2/

Use the scripts in ros2/src/odin_ros_driver/script/ if your environment expects them.
