Adds rosbridge_suite to the Jetson stack so the browser dashboard can
subscribe to ROS2 topics via roslibjs over ws://jetson:9090.
docker-compose.yml
New service: saltybot-rosbridge
- Runs saltybot_bringup/launch/rosbridge.launch.py
- network_mode: host → port 9090 directly reachable on Jetson LAN
- Depends on saltybot-ros2, stm32-bridge, csi-cameras
saltybot_bringup/launch/rosbridge.launch.py
- rosbridge_websocket node (port 9090, params from rosbridge_params.yaml)
- 4× image_transport/republish nodes: compress CSI camera streams
/camera/<name>/image_raw → /camera/<name>/image_raw/compressed (JPEG 75%)
saltybot_bringup/config/rosbridge_params.yaml
Whitelisted topics:
/map /scan /tf /tf_static
/saltybot/imu /saltybot/balance_state
/cmd_vel
/person/*
/camera/*/image_raw/compressed
max_message_size: 10 MB (OccupancyGrid headroom)
saltybot_bringup/SENSORS.md
Added rosbridge connection section with roslibjs snippet,
topic reference table, bandwidth estimates, and throttle_rate tips.
saltybot_bringup/package.xml
Added exec_depend: rosbridge_server, image_transport,
image_transport_plugins (all already installed in Docker image).
