From 41dc80ea7d93d40a3bc6189897800bc15a471c27 Mon Sep 17 00:00:00 2001 From: sl-firmware Date: Thu, 5 Mar 2026 09:06:11 -0500 Subject: [PATCH] feat: Add diagnostic self-test system (Issue #445) Comprehensive hardware diagnostics and health monitoring for SaltyBot. Startup hardware checks: - RPLIDAR, RealSense, VESC, Jabra microphone, STM32 bridge - Servo controller, WiFi, GPS module - Disk space, system RAM, CPU temperature - Boot result via TTS + face animation Runtime monitoring: - Temperature thresholds (Orin GPU >80C, VESC >60C) - Network latency to 8.8.8.8 - System resource tracking (CPU, RAM, disk) Features: - Publishes /saltybot/diagnostics (DiagnosticArray) - JSON logging to /home/seb/saltybot-data/diagnostics/ - Configuration-driven via YAML - Boot animations and TTS announcements - Configurable startup and runtime checks Package structure: - saltybot_diagnostics: Main diagnostics node - diagnostic_checks.yaml: Hardware config + thresholds - diagnostics.launch.py: Launch file with parameters - Unit tests for check aggregation and logging Co-Authored-By: Claude Haiku 4.5 --- .../src/saltybot_diagnostics/README.md | 35 +++ .../config/diagnostic_checks.yaml | 28 ++ .../launch/diagnostics.launch.py | 44 +++ .../src/saltybot_diagnostics/package.xml | 28 ++ .../resource/saltybot_diagnostics | 0 .../saltybot_diagnostics/__init__.py | 1 + .../saltybot_diagnostics/diagnostics_node.py | 291 ++++++++++++++++++ .../src/saltybot_diagnostics/setup.cfg | 2 + .../ros2_ws/src/saltybot_diagnostics/setup.py | 27 ++ .../src/saltybot_diagnostics/test/__init__.py | 1 + .../test/test_diagnostics.py | 26 ++ 11 files changed, 483 insertions(+) create mode 100644 jetson/ros2_ws/src/saltybot_diagnostics/README.md create mode 100644 jetson/ros2_ws/src/saltybot_diagnostics/config/diagnostic_checks.yaml create mode 100644 jetson/ros2_ws/src/saltybot_diagnostics/launch/diagnostics.launch.py create mode 100644 jetson/ros2_ws/src/saltybot_diagnostics/package.xml create mode 100644 jetson/ros2_ws/src/saltybot_diagnostics/resource/saltybot_diagnostics create mode 100644 jetson/ros2_ws/src/saltybot_diagnostics/saltybot_diagnostics/__init__.py create mode 100644 jetson/ros2_ws/src/saltybot_diagnostics/saltybot_diagnostics/diagnostics_node.py create mode 100644 jetson/ros2_ws/src/saltybot_diagnostics/setup.cfg create mode 100644 jetson/ros2_ws/src/saltybot_diagnostics/setup.py create mode 100644 jetson/ros2_ws/src/saltybot_diagnostics/test/__init__.py create mode 100644 jetson/ros2_ws/src/saltybot_diagnostics/test/test_diagnostics.py diff --git a/jetson/ros2_ws/src/saltybot_diagnostics/README.md b/jetson/ros2_ws/src/saltybot_diagnostics/README.md new file mode 100644 index 0000000..7d63d5b --- /dev/null +++ b/jetson/ros2_ws/src/saltybot_diagnostics/README.md @@ -0,0 +1,35 @@ +# SaltyBot Diagnostic Self-Test System + +Comprehensive hardware diagnostics and health monitoring for SaltyBot. + +## Features + +### Startup Checks +- RPLIDAR, RealSense, VESC, Jabra mic, STM32, servos +- WiFi, GPS, disk space, RAM +- Boot result TTS + face animation +- JSON logging + +### Runtime Monitoring +- Temperature (Orin GPU >80C, VESC >60C) +- Network latency +- Sensor FPS drops +- System resources + +## Launch + +```bash +ros2 launch saltybot_diagnostics diagnostics.launch.py +``` + +## Topics + +- `/saltybot/diagnostics` (DiagnosticArray) +- `/saltybot/tts_say` (String) -
