feat: ROS2 bag recording manager (Issue #615 )
...
Upgrades saltybot_bag_recorder (Issue #488 ) with:
- Motion-triggered auto-record: subscribes /cmd_vel, starts on non-zero
velocity, stops after 30s idle timeout (configurable)
- Auto-split at 1 GB or 10 min via subprocess restart
- USB/NVMe storage selection: ordered priority list, picks first path
with >= 2 GB free (/media/usb0 -> /media/usb1 -> /mnt/nvme -> ~/bags)
- Disk monitoring: warns at 70%, triggers cleanup of bags >7 days at 80%
- JSON status on /saltybot/bag_recorder/status at 1 Hz
- Services: /saltybot/bag_recorder/{start,stop,split}
(legacy /saltybot/{start,stop}_recording kept for compatibility)
- bag_policy.py: pure-Python MotionState, DiskInfo, StorageSelector,
BagPolicy — ROS2-free, fully unit-testable
- 76 unit tests passing

feat: Steering PID for differential drive (Issue #616 )
...
Closed-loop yaw-rate controller that converts Jetson Twist.angular.z
to a differential wheel speed offset using IMU gyro Z as feedback.
- include/steering_pid.h + src/steering_pid.c: PID with anti-windup
(integral clamped to ±200 counts) and rate limiter (10 counts/ms
max output change) to protect balance PID from sudden steering steps.
JLINK_TLM_STEERING (0x8A) telemetry at 10 Hz.
- include/mpu6000.h + src/mpu6000.c: expose yaw_rate (board_gz) in
IMUData so callers have direct bias-corrected gyro Z feedback.
- include/jlink.h + src/jlink.c: add JLINK_TLM_STEERING (0x8A),
jlink_tlm_steering_t (8 bytes), jlink_send_steering_tlm().
- test/test_steering_pid.c: 78 unit tests (host build with gcc),
all passing.
Usage (main loop):
steering_pid_set_target(&s, jlink_state.steer * STEER_OMEGA_SCALE);
int16_t steer_out = steering_pid_update(&s, imu.yaw_rate, dt);
motor_driver_update(&motor, balance_cmd, steer_out, now_ms);

feat: RealSense depth obstacle detection (Issue #611 )
...
New package saltybot_obstacle_detect — RANSAC ground plane fitting on
D435i depth images with 2D grid BFS obstacle clustering.
ground_plane.py (pure Python + numpy):
fit_ground_plane(pts, n_iter=50, inlier_thresh_m=0.06): RANSAC over 3D
point cloud in camera optical frame (+Z forward). Samples 3 points, fits
plane via cross-product, counts inliers, refines via SVD on best inlier
set. Orients normal toward -Y (upward in world). Returns (normal, d).
height_above_plane(pts, plane): signed h = d - n·p (h>0 = above ground).
obstacle_mask(pts, plane, min_h, max_h): min_obstacle_h_m < h < max_h.
ground_mask(pts, plane, thresh): inlier classification.
obstacle_clusterer.py (pure Python + numpy):
cluster_obstacles(pts, heights, cell_m=0.30, min_pts=5): projects
obstacle 3D points onto (X,Z) bird's-eye plane, discretises into grid
cells, runs 4-connected BFS flood-fill, returns ObstacleCluster list
sorted by forward distance. ObstacleCluster: centroid(3), radius_m,
height_m, n_pts + distance_m/lateral_m properties.
obstacle_detect_node.py (ROS2 node 'obstacle_detect'):
- Subscribes: /camera/depth/camera_info (latched, once),
/camera/depth/image_rect_raw (BEST_EFFORT, 30Hz float32 depth).
- Pipeline: stride downsample (default 8x → 80x60) → back-project to
3D → RANSAC ground plane (temporally blended α=0.3) → obstacle mask
(min_h=0.05m, max_h=0.80m) → BFS clustering → alert classification.
- Publishes:
/saltybot/obstacles (MarkerArray): SPHERE markers colour-coded
DANGER(red)/WARN(yellow)/CLEAR(green) + distance TEXT labels.
/saltybot/obstacles/cloud (PointCloud2): xyz float32 non-ground pts.
/saltybot/obstacles/alert (String JSON): alert_level, closest_m,
obstacle_count, per-obstacle {x,y,z,radius_m,height_m,level}.
- Safety zone integration (depth_estop_enabled=false by default):
DANGER → zero Twist to depth_estop_topic (/cmd_vel_input) feeds
into safety_zone's cmd_vel chain for independent depth e-stop.
config/obstacle_detect_params.yaml: all tuneable parameters with comments.
launch/obstacle_detect.launch.py: single node with params_file arg.
test/test_ground_plane.py: 10 unit tests (RANSAC correctness, normal
orientation, height computation, inlier/obstacle classification).
test/test_obstacle_clusterer.py: 8 unit tests (single/dual cluster,
distance sort, empty, min_pts filter, centroid accuracy, range clip).

feat: Nav2 integration with UWB localization (Issue #599 )
...
New package saltybot_nav2_uwb replacing AMCL-based localization with
UWB-IMU EKF fused pose. Key components:
- uwb_pose_bridge_node: subscribes /saltybot/pose/fused_cov (from EKF),
computes map→odom TF via T_map_odom = T_map_base × inv(T_odom_base),
broadcasts at 20 Hz. Publishes /initialpose on first valid pose.
- waypoint_sequencer.py: pure-Python state machine (IDLE→RUNNING→
SUCCEEDED/ABORTED/CANCELED) for sequential waypoint execution.
- waypoint_follower_node: action server on /saltybot/nav/follow_waypoints
(nav2_msgs/FollowWaypoints), sends each goal to Nav2 NavigateToPose
in sequence; JSON topic /saltybot/nav/waypoints for operator use.
- nav2_uwb_params.yaml: DWB controller capped at 1.0 m/s, global+local
costmap with /scan (RPLIDAR), rolling-window global costmap (no static
map needed), AMCL removed from lifecycle manager.
- nav2_uwb.launch.py: bridge (t=0) → Nav2 (t=2s) → waypoint follower
(t=4s) with LogInfo markers.
- 65 unit tests passing (waypoint dataclass, sequencer state machine,
2-D TF maths, progress tracking).

feat: Multi-sensor pose fusion node (Issue #595 )
...
New package saltybot_pose_fusion — EKF fusing UWB+IMU absolute pose,
visual odometry velocity, and raw IMU into a single authoritative pose.
pose_fusion_ekf.py (pure Python, no ROS2 deps):
PoseFusionEKF — state [x, y, θ, vx, vy, ω], 6-state EKF.
- predict_imu(ax_body, ay_body, omega, dt): body-frame IMU predict step
with Jacobian F, bias-compensated accel, process noise Q.
- update_uwb_position(x, y, sigma_m): absolute position measurement
(H=[1,0,0,0,0,0; 0,1,0,0,0,0]) from UWB+IMU fused stream.
- update_uwb_heading(heading_rad, sigma_rad): heading measurement.
- update_vo_velocity(vx_body, omega, ...): VO velocity measurement —
body-frame vx rotated to world via cos/sin(θ), updates [vx,vy,ω] state.
- Joseph-form covariance update for numerical stability.
- Dual dropout clocks: uwb_dropout_s, vo_dropout_s (reset on each update).
- Velocity damping when uwb_dropout_s > 2s.
- Sensor weight parameters: sigma_uwb_pos_m, sigma_uwb_head_rad,
sigma_vo_vel_m_s, sigma_vo_omega_r_s, sigma_imu_accel/gyro,
sigma_vel_drift, dropout_vel_damp.
pose_fusion_node.py (ROS2 node 'pose_fusion'):
- Subscribes: /imu/data (Imu, 200Hz → predict), /saltybot/pose/fused_cov
(PoseWithCovarianceStamped, 10Hz → position+heading update, σ extracted
from message covariance when use_uwb_covariance=true), /saltybot/visual_odom
(Odometry, 30Hz → velocity update, σ from twist covariance).
- Publishes: /saltybot/pose/authoritative (PoseWithCovarianceStamped),
/saltybot/pose/status (String JSON, 10Hz).
- TF2: map→base_link broadcast at IMU rate.
- Suppresses output when uwb_dropout_s > uwb_dropout_max_s (10s).
- Warns (throttled) on UWB/VO dropout.
config/pose_fusion_params.yaml: sensor weights + dropout thresholds.
launch/pose_fusion.launch.py: single node launch with params_file arg.
test/test_pose_fusion_ekf.py: 13 unit tests — init, predict, UWB/VO
updates, dropout reset, covariance shape/convergence, sigma override.

feat: MQTT-to-ROS2 phone sensor bridge (Issue #601 )
...
Add saltybot_phone/mqtt_ros2_bridge_node.py — ROS2 node bridging the three
MQTT topics published by phone/sensor_dashboard.py into typed ROS2 messages:
saltybot/phone/imu → /saltybot/phone/imu sensor_msgs/Imu
saltybot/phone/gps → /saltybot/phone/gps sensor_msgs/NavSatFix
saltybot/phone/battery → /saltybot/phone/battery sensor_msgs/BatteryState
(status) → /saltybot/phone/bridge/status std_msgs/String
Key design:
- paho-mqtt loop_start() runs in dedicated network thread; on_message
enqueues (topic, payload) pairs into a thread-safe queue
- ROS2 timer drains queue at 50 Hz — all publishing stays on executor
thread, avoiding any rclpy threading concerns
- Timestamp alignment: uses ROS2 wall clock by default; opt-in
use_phone_timestamp param uses phone epoch ts when drift < warn_drift_s
- IMU: populates accel + gyro with diagonal covariance; orientation_cov[0]=-1
(unknown per REP-145)
- GPS: NavSatStatus.STATUS_FIX for gps/fused/network providers; full 3×3
position covariance from accuracy_m; COVARIANCE_TYPE_APPROXIMATED
- Battery: pct→percentage [0-1], temp Kelvin, health/status mapped from
Android health strings, voltage/current=NaN (unavailable on Android)
- Input validation: finite value checks on IMU, lat/lon range on GPS,
pct [0-100] on battery; bad messages logged at DEBUG and counted
- Status topic at 0.2 Hz: JSON {mqtt_connected, rx/pub/err counts,
age_s per sensor, queue_depth}
- Auto-reconnect via paho reconnect_delay_set (5 s → 20 s max)
Add launch/mqtt_bridge.launch.py with args: mqtt_host, mqtt_port,
reconnect_delay_s, use_phone_timestamp, warn_drift_s, imu_accel_cov,
imu_gyro_cov.
Register mqtt_ros2_bridge console script in setup.py.
Add python3-paho-mqtt exec_depend to package.xml.

sector 7 (0x08060000, 8x64-byte slots) on subsequent boot
- MPU Region 0 stack guard (32 B at __stack_end, no-access) ->
MemManage fault detected as FAULT_STACK_OVF
- Brownout detect via RCC_CSR_BORRSTF on boot -> FAULT_BROWNOUT
- Watchdog reset detection delegates to existing watchdog.c
- LED blink codes on LED2 (PC14, active-low) for 10 s post-recovery:
HARDFAULT=3, WATCHDOG=2, BROWNOUT=1, STACK_OVF=4 fast blinks
- fault_led_tick(), fault_log_read(), fault_log_get_count(),
fault_get_last_type(), fault_log_clear(), FAULT_ASSERT() macro
- jlink.h: add JLINK_CMD_FAULT_LOG_GET (0x0F), JLINK_TLM_FAULT_LOG
(0x86), jlink_tlm_fault_log_t (20 bytes), fault_log_req in JLinkState,
jlink_send_fault_log() declaration
- jlink.c: dispatch JLINK_CMD_FAULT_LOG_GET; implement
jlink_send_fault_log() (26-byte CRC16-XModem framed response)
- main.c: call fault_handler_init() first in main(); send fault log
TLM on boot if prior fault recorded; fault_led_tick() in main loop;
handle fault_log_req flag to respond to Jetson queries
