feat: rosbridge WebSocket server for web UI (port 9090)
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).

feat: 4x IMX219 surround vision + Nav2 camera obstacle layer (Phase 2c)
New ROS2 package saltybot_surround:
surround_costmap_node
- Subscribes to /camera/{front,left,rear,right}/image_raw
- Detects obstacles via Canny edge detection + ground projection
- Pinhole back-projection: pixel row → forward distance (d = h*fy/(v-cy))
- Rotates per-camera points to base_link frame using known camera yaws
- Publishes /surround_vision/obstacles (PointCloud2, 5 Hz)
- Catches chairs, glass walls, people that RPLIDAR misses
- Placeholder IMX219 fisheye calibration (hook for real cal via cv2.fisheye)
surround_vision_node
- IPM homography computed from camera height + pinhole model
- 4× bird's-eye patches composited into 240×240px 360° overhead view
- Publishes /surround_vision/birdseye (Image, 10 Hz)
- Robot footprint + compass overlay
surround_vision.launch.py
- Launches both nodes with surround_vision_params.yaml
- start_cameras arg: set false when csi-cameras container runs separately
Updated:
- jetson/config/nav2_params.yaml add surround_cameras PointCloud2 source
to local + global costmap obstacle_layer
- jetson/docker-compose.yml add saltybot-surround service
(depends_on: csi-cameras, start_cameras:=false)
- projects/saltybot/SLAM-SETUP-PLAN.md Phase 2c ✅ Done
Calibration TODO (run after hardware assembly):
ros2 run camera_calibration cameracalibrator --size 8x6 --square 0.025 \
image:=/camera/front/image_raw camera:=/camera/front
Replace placeholder K/D in surround_costmap_node._undistort()

(front/left/rear/right), 640x480x30fps, includes TF launch automatically
- launch/camera_tf.launch.py: static TF for 4 cameras at 90deg intervals
on sensor_head_link (r=5cm offset), yaw 0/90/180/-90 deg
- package.xml, setup.py, setup.cfg, __init__.py, resource marker
- config/cameras_params.yaml: per-camera device/frame/offset configuration

feat: Nav2 path planning + obstacle avoidance (Phase 2b)
Integrates Nav2 autonomous navigation stack with RTAB-Map SLAM on Orin
Nano Super. No AMCL/map_server needed — RTAB-Map provides /map + TF.
New files:
- jetson/config/nav2_params.yaml DWB controller,
NavFn planner, RPLIDAR obstacle layer, RealSense voxel layer;
10Hz local / 5Hz global costmap; robot_radius 0.15m, max_vel 1.0 m/s
- jetson/ros2_ws/src/saltybot_bringup/launch/nav2.launch.py
wraps nav2_bringup navigation_launch with saltybot params + BT XML
- jetson/ros2_ws/src/saltybot_bringup/behavior_trees/
navigate_to_pose_with_recovery.xml BT: replan@1Hz, DWB follow,
recovery: clear maps → spin 90° → wait 5s → back up 0.30m
Updated:
- jetson/docker-compose.yml add saltybot-nav2 service
(depends_on: saltybot-ros2)
- jetson/ros2_ws/src/saltybot_bringup/setup.py install behavior_trees/*.xml
- jetson/ros2_ws/src/saltybot_bringup/package.xml add rtabmap_ros + nav2_bringup
- projects/saltybot/SLAM-SETUP-PLAN.md Phase 2b ✅ Done

ROS2 Humble via native apt, added ros-humble-rtabmap-ros,
ros-humble-v4l2-camera for future IMX219 CSI (Phase 2c)
New: slam_rtabmap.launch.py — Orin primary SLAM entry point
RTAB-Map with subscribe_scan (RPLIDAR) + subscribe_rgbd (D435i)
Replaces slam_toolbox as docker-compose default
New: config/rtabmap_params.yaml — Orin-optimized
DetectionRate 10Hz, MaxFeatures 1000, Grid/3D true,
TimeThr 0 (no limit), Mem/STMSize 0 (unlimited)
Updated: config/realsense_d435i.yaml — 848x480x30, pointcloud enabled
Updated: config/slam_toolbox_params.yaml — 10Hz rate, 1s map interval
Updated: SLAM-SETUP-PLAN.md — full rewrite for Orin: arch diagram,
Phase 2c IMX219 plan (4x 160° CSI surround), 25W power budget
docker-compose.yml: image tag jetson-orin, default → slam_rtabmap.launch.py

feat(bd-a2j): RealSense D435i + RPLIDAR A1M8 ROS2 driver integration
Adds saltybot_bringup ROS2 package with four launch files:
- realsense.launch.py — D435i at 640x480x15fps, IMU unified topic
- rplidar.launch.py — RPLIDAR A1M8 via /dev/rplidar udev symlink
- sensors.launch.py — both sensors + static TF (base_link→laser/camera)
- slam.launch.py — sensors + slam_toolbox online_async (compose entry point)
Sensor config YAMLs (mounted at /config/ in container):
- realsense_d435i.yaml — Nano power-budget settings (15fps, no pointcloud)
- rplidar_a1m8.yaml — Standard scan mode, 115200 baud, laser frame
- slam_toolbox_params.yaml — Nano-tuned (2Hz processing, 5cm resolution)
Fixes docker-compose volume mount: ./ros2_ws/src:/ros2_ws/src
(was ./ros2_ws:/ros2_ws/src — would have double-nested the src directory)
Topic reference and verification commands in SENSORS.md.
