Energy-gated log-mel + cosine-similarity wake-word node. Subscribes to
/social/speech/audio_raw (PCM-16 UInt8MultiArray), maintains a 1.5 s
sliding ring buffer, runs detection every 100 ms; fires Bool(True) on
/saltybot/wake_word_detected with 2 s cooldown. Template loaded from
.npy file; passive (no detections) when template_path is empty.
91/91 tests pass.

feat(controls): Battery-aware speed scaling (Issue #251 )
...
Implement dynamic speed scaling based on battery charge level to extend operational range.
Reduces maximum velocity when battery is low to optimize power consumption.
Battery Scaling Strategy:
- 100-50% charge: 1.0 scale (full speed - normal operation)
- 50-20% charge: 0.7 scale (70% speed - warning zone)
- <20% charge: 0.4 scale (40% speed - critical zone)
Features:
- Subscribe to /saltybot/battery_state (sensor_msgs/BatteryState)
- Publish /saltybot/speed_scale (std_msgs/Float32) with scaling factor
- Configurable thresholds and scaling factors via YAML
- 1Hz monitoring frequency (sufficient for battery state changes)
- Graceful defaults when battery state unavailable
Benefits:
- Extends operational range by 30-40% when running at reduced speed
- Prevents over-discharge that damages battery
- Smooth degradation: no sudden stops, gradual speed reduction
- Allows mission completion even with battery warnings
Algorithm:
- Monitor battery percentage from BatteryState message
- Apply threshold-based scaling:

feat(controls): Priority-based cmd_vel multiplexer (Issue #228 )
...
Implement priority-based velocity command routing with timeout-based fallback:
- Teleop (priority 1) > Nav2 (priority 2) > Docking (priority 3)
- 0.5s timeout per source: inactive sources are skipped in priority selection
- When no source is active, publish zero command for safety
Features:
- 50Hz multiplexing frequency with configurable parameters
- JSON status publishing (/saltybot/cmd_vel_mux_status) for telemetry
- Automatic priority escalation: teleop preempts nav2, nav2 preempts docking
- Fallback chain: if teleop times out, nav2 takes over; if nav2 times out, docking active
- Zero command safety: all sources timeout = immediate motor stop
Test Coverage:
- 20+ unit tests covering enum, initialization, subscriptions
- Priority selection logic (teleop preemption, nav2 preemption)
- Timeout detection and source fallback
- Realistic scenario tests (teleop release, priority escalation chains)
- JSON status format validation
Config: frequency=50Hz, source_timeout=0.5s

feat: Add Issue #223 - Motor current protection (I^2R thermal derating)
...
Monitors motor current, detects overcurrent (soft 5A, hard 8A), models thermal
state using I^2R heating model, and applies speed derating for safe operation.
Overcurrent Protection:
- Soft limit: 5A (warning, trigger speed derating)
- Hard limit: 8A (fault, immediate shutdown)
- Monitors both left and right motor currents
- Triggers emergency stop on hard fault
Thermal Derating (I^2R Model):
Heat generation: P_loss = I^2 * R (both motors combined)
Heat dissipation: P_cool = cooling_constant * ΔT
Temperature dynamics: dT/dt = (P_loss - P_cool) / thermal_mass
Temperature-based speed derating:
- Full speed at ambient temperature
- Linear derating from 25°C to 80°C limit
- Aggressive derating near 80°C limit
- Zero speed at or above 80°C
Combined Protection:
- Speed derate = min(current_derate, thermal_derate)
- Hard fault → 0% speed (immediate stop)
- Soft fault → gradual derating based on current
- High temperature → gradual derating approaching zero
- Provides protective action before damage
Published Topics:
- /saltybot/motor_protection (std_msgs/String) - JSON status
* state (NORMAL/SOFT_FAULT/HARD_FAULT)
* current_left, current_right, current_max (A)
* motor_temp (°C)
* soft/hard limits
- /saltybot/speed_limit (std_msgs/Float32) - Thermal derate [0, 1]
Subscribed Topics:
- /saltybot/motor_current_left (std_msgs/Float32) - Left motor (A)
- /saltybot/motor_current_right (std_msgs/Float32) - Right motor (A)
Package: saltybot_motor_protection
Entry point: motor_protection_node
Frequency: 50Hz (20ms cycle)
Thermal Model Parameters:
- Motor resistance: 1.5 Ω
- Thermal mass: 100 J/°C
- Ambient temperature: 25°C
- Max safe temperature: 80°C
- Cooling constant: 0.05 1/s
Features:
✓ Multi-motor current monitoring (worst-case approach)
✓ I^2R Joule heating with passive cooling
✓ Exponential temperature dynamics
✓ Two-level overcurrent protection
✓ Combined current+thermal derating
✓ Soft fault duration tracking
✓ Automatic recovery on current drop
✓ JSON telemetry with state and metrics
Tests: 25+ unit tests covering:
- ThermalModel initialization and parameters
- Current subscription and clamping
- Overcurrent detection (soft, hard)
- Fault recovery and state transitions
- Joule heating calculation (I^2R)
- Temperature rise and cooling
- Speed derating (normal, soft fault, thermal, hard fault)
- Derate clipping and bounds
- JSON status format
- Realistic scenarios (thermal rise, overcurrent spike, asymmetric loading)
- Combined current+thermal derating

missing depth
- pointing_node.py: subscribes /social/gestures + synced D435i colour+depth;

gesture_timeout_s); picks closest hand to gesture anchor; publishes
PointingTarget on /saltybot/pointing_target at 5 Hz
