feat: Motor current monitoring and overload protection (Issue #584 )
...
Adds ADC-based motor current sensing with configurable overload threshold,
soft PWM limiting, hard cutoff on sustained overload, and auto-recovery.
Changes:
- include/motor_current.h: MotorCurrentState enum (NORMAL/SOFT_LIMIT/COOLDOWN),
thresholds (5A hard, 4A soft, 2s overload, 10s cooldown), full API
- src/motor_current.c: reads battery_adc_get_current_ma() each tick (reuses
existing ADC3 IN13/PC3 DMA sampling); linear PWM scale in soft-limit zone
(scale256 fixed-point); fault counter + one-tick fault_pending flag for
main-loop fault log integration; telemetry at MOTOR_CURR_TLM_HZ (5 Hz)
- include/pid_flash.h: add pid_sched_entry_t (16 bytes), pid_sched_flash_t
(128 bytes at 0x0807FF40), PID_SCHED_MAX_BANDS=6, pid_flash_load_schedule(),
pid_flash_save_all() — fixes missing types needed by jlink.h (Issue #550 )
- src/pid_flash.c: implement flash_write_words() helper, pid_flash_load_schedule(),
pid_flash_save_all() — single sector-7 erase covers both schedule and PID records
- include/jlink.h: add JLINK_TLM_MOTOR_CURRENT (0x86), jlink_tlm_motor_current_t
(8 bytes: current_ma, limit_pct, state, fault_count), jlink_send_motor_current_tlm()
- src/jlink.c: implement jlink_send_motor_current_tlm() (14-byte frame)
Motor overload state machine:
MC_NORMAL : current_ma < 4000 mA — full PWM authority
MC_SOFT_LIMIT : 4000-5000 mA — linear reduction (0% at 4A → 100% at 5A)
MC_COOLDOWN : >5A sustained 2s → zero output for 10s then NORMAL
Main-loop integration:
motor_current_tick(now_ms);
if (motor_current_fault_pending()) fault_log_append(FAULT_MOTOR_OVERCURRENT);
cmd = motor_current_apply_limit(balance_pid_output());
motor_current_send_tlm(now_ms);

feat: Visual odometry from RealSense stereo ORB (Issue #586 )
...
Adds stereo ORB-based visual odometry to saltybot_visual_odom package.
New modules:
- orb_stereo_matcher.py: ORB feature detection (cv2.ORB_create) with BFMatcher
NORM_HAMMING + Lowe ratio test for temporal matching (infra1 prev→curr).
Stereo scale method matches infra1↔infra2 under epipolar row constraint
(|Δrow|≤2px), computes depth = baseline_m * fx / disparity.
- stereo_orb_node.py: StereoOrbNode subscribes to infra1+infra2+depth
(ApproximateTimeSynchronizer 3-topic), detects/matches ORB temporally,
estimates SE(3) via Essential matrix (5-point RANSAC) using StereoVO,
recovers metric scale from D435i aligned depth (primary) or stereo
baseline disparity (fallback). Publishes nav_msgs/Odometry on
/saltybot/visual_odom and broadcasts TF2 odom→camera_link. Baseline
auto-updated from infra2 camera_info Tx (overrides parameter).
- config/stereo_orb_params.yaml, launch/stereo_orb.launch.py
- setup.py: adds stereo_orb entrypoint, installs launch+config dirs

feat: RPLIDAR safety zone detector (Issue #575 )
...
Add saltybot_safety_zone — ROS2 Python node that processes the RPLIDAR
A1M8 /scan into three concentric 360° safety zones, latches an e-stop
when DANGER is detected in the forward arc, and overrides /cmd_vel to
zero while the latch is active.
Zone thresholds (default):
DANGER < 0.30 m — latching e-stop in forward arc
WARN < 1.00 m — advisory (published in sector data)
CLEAR otherwise
Sector grid:
36 sectors of 10° each (sector 0 = robot forward, CCW positive).
Per-sector: angle_deg, zone, min_range_m, in_forward_arc flag.
E-stop behaviour:
- Latches after estop_debounce_frames (2) consecutive DANGER scans
in the forward arc (configurable ±30°, or all-arcs mode).
- While latched: zero Twist published to /cmd_vel every scan + every
incoming /cmd_vel_input message is blocked.
- Clear only via service (obstacle must be gone):
/saltybot/safety_zone/clear_estop (std_srvs/Trigger)
Published topics:
/saltybot/safety_zone String/JSON every scan
— per-sector {sector, angle_deg, zone, min_range_m, forward}
— estop_active, estop_reason, danger_sectors[], warn_sectors[]
/saltybot/safety_zone/status String/JSON 10 Hz
— forward_zone, closest_obstacle_m, danger/warn counts
/cmd_vel Twist zero when e-stopped
Subscribed topics:
/scan LaserScan — RPLIDAR A1M8
/cmd_vel_input Twist — upstream velocity (pass-through / block)

Implements a speed-dependent PID gain scheduler that interpolates Kp/Ki/Kd
across a configurable table of velocity breakpoints, replacing the fixed
single-gain PID used previously.
Changes:
- include/pid_flash.h: add pid_sched_entry_t (16-byte entry), pid_sched_flash_t
(128-byte record at 0x0807FF40), pid_flash_load_schedule(), pid_flash_save_all()
(atomic single-sector erase for both schedule and single-PID records)
- src/pid_flash.c: implement load_schedule and save_all; single erase covers
both records at 0x0807FF40 (schedule) and 0x0807FFC0 (single PID)
- include/pid_schedule.h: API header -- init, get_gains, apply, set/get table,
flash_save, active_band_idx, get_default_table
- src/pid_schedule.c: linear interpolation between sorted speed-band entries;
integrator reset on band transition; default 3-band table (0/0.3/0.8 m/s)
- include/jlink.h: add SCHED_GET (0x0C), SCHED_SET (0x0D), SCHED_SAVE (0x0E)
commands; TLM_SCHED (0x85); jlink_tlm_sched_t; JLinkSchedSetBuf;
sched_get_req, sched_save_req fields in JLinkState; include pid_flash.h
- src/jlink.c: dispatch SCHED_GET/SET/SAVE; implement jlink_send_sched_telemetry,
jlink_get_sched_set; add JLinkSchedSetBuf static buffer
- test/test_pid_schedule.c: 48 unit tests -- all passing (gcc host build)
Flash layout (sector 7):
0x0807FF40 pid_sched_flash_t (128 bytes) -- schedule
0x0807FFC0 pid_flash_t ( 64 bytes) -- single PID (existing)

/camera/color/image_raw, /camera/depth/image_rect_raw,
/camera/color/camera_info, /scan, /imu/data,
/saltybot/uwb/range, /saltybot/battery, /saltybot/motor_daemon/status
Each sensor: OK/WARN/ERROR based on topic age vs warn_s/error_s thresholds.
Critical sensors (camera, lidar, imu, motor_daemon) escalate overall status.
Files added:
sensor_health_node.py — SensorWatcher + SensorHealthNode
config/sensor_health_params.yaml — per-sensor thresholds
launch/sensor_health.launch.py
test/test_sensor_health.py — 35 tests, all passing
setup.py/package.xml updated: sensor_msgs, diagnostic_msgs deps + new entry point.

feat: ESP32 UWB Pro anchor firmware — DS-TWR responder (Issue #544 )
...
Anchor firmware for Makerfabs ESP32 UWB Pro (DW3000 chip). Two anchors
mount on SaltyBot (port/starboard), USB-connected to Jetson Orin.
- DS-TWR responder: Poll→Resp→Final with ±10cm accuracy
- Streams +RANGE:<id>,<mm>,<rssi_dbm> on Serial 115200
- AT command interface: AT+RANGE?, AT+RANGE_ADDR=, AT+ID?
- ANCHOR_ID 0/1 set at build time (env:anchor0 / env:anchor1)
- PlatformIO config for Makerfabs MaUWB_DW3000 library
- udev rules for /dev/uwb-anchor0 /dev/uwb-anchor1 USB symlinks
- Pin map: SCK=18 MISO=19 MOSI=23 CS=21 RST=27 IRQ=34

feat: ROS2 UWB position node (Issue #546 )
...
Add saltybot_uwb_position — ROS2 Python package that reads JSON range
measurements from an ESP32 DW3000 UWB tag over USB serial, trilaterates
the robot's absolute position from 3+ fixed infrastructure anchors, and
publishes position + TF2 to the rest of the stack.
Serial protocol (one JSON line per frame):
Full frame: {"ts":…, "ranges": [{"id":0,"d_mm":1500,"rssi":-65}, …]}
Per-anchor: {"id":0, "d_mm":1500, "rssi":-65.0}
Accepts both "d_mm" and "range_mm" field names.
Trilateration (trilateration.py, numpy, no ROS deps):
Linear least-squares: linearise sphere equations around anchor 0,
solve (N-1)x2 (2D) or (N-1)x3 (3D) system via np.linalg.lstsq.
2D mode (default): robot_z fixed, needs >=3 anchors.
3D mode (solve_z=true): full 3D, needs >=4 anchors.
Outlier rejection:
After initial solve, compute per-anchor residual |r_meas - r_pred|.
Reject anchors with residual > outlier_threshold_m (0.4 m default).
Re-solve with inliers if >= min_anchors remain.
Track consecutive outlier strikes; flag in /status after N strikes.
Kalman filter (KalmanFilter3D, constant-velocity, 6-state, numpy):
Predict-only coasting when anchors drop below minimum.
Q=0.05, R=0.10 (tunable).
Topics:
/saltybot/uwb/pose PoseStamped 10 Hz Kalman-filtered position
/saltybot/uwb/range/<id> UwbRange on arrival, raw per-anchor ranges
/saltybot/uwb/status String/JSON 10 Hz state+residuals+flags
TF2: uwb_link -> map (identity rotation)
Anchor config: flat float arrays in YAML.
Default layout: 4-anchor 5x5m room at 2m height.
