Add comprehensive integration testing for complete ROS2 system stack: Integration Tests (test_integration_full_stack.py): - Verifies all ROS2 nodes launch successfully - Checks critical topics are published (sensors, nav, control) - Validates system component health and stability - Tests launch file validity and configuration - Covers indoor/outdoor/follow modes Launch Testing (test_launch_full_stack.py): - Validates launch file syntax and configuration - Verifies all required packages are installed - Checks launch sequence timing - Validates conditional logic for optional components Test Coverage: ✓ SLAM/RTAB-Map (indoor mode) ✓ Nav2 navigation stack ✓ Perception (YOLOv8n person detection) ✓ Control (cmd_vel bridge, STM32 bridge) ✓ Audio pipeline and monitoring ✓ Sensors (LIDAR, RealSense, UWB, CSI cameras) ✓ Battery and temperature monitoring ✓ Autonomous docking behavior ✓ TF2 tree and odometry Usage: pytest test/test_integration_full_stack.py -v pytest test/test_launch_full_stack.py -v Documentation: See test/README_INTEGRATION_TESTS.md for detailed information.

Jetson Nano — AI/SLAM Platform Setup
Self-balancing robot: Jetson Nano dev environment for ROS2 Humble + SLAM stack.
Stack
| Component | Version / Part |
|---|---|
| Platform | Jetson Nano 4GB |
| JetPack | 4.6 (L4T R32.6.1, CUDA 10.2) |
| ROS2 | Humble Hawksbill |
| DDS | CycloneDDS |
| SLAM | slam_toolbox |
| Nav | Nav2 |
| Depth camera | Intel RealSense D435i |
| LiDAR | RPLIDAR A1M8 |
| MCU bridge | STM32F722 (USB CDC @ 921600) |
Quick Start
# 1. Host setup (once, on fresh JetPack 4.6)
sudo bash scripts/setup-jetson.sh
# 2. Build Docker image
bash scripts/build-and-run.sh build
# 3. Start full stack
bash scripts/build-and-run.sh up
# 4. Open ROS2 shell
bash scripts/build-and-run.sh shell

Power Budget (Summary)
| Scenario | Total |
|---|---|
| Idle | 2.9W |
| Nominal (SLAM active) | ~10.2W |
| Peak | 15.4W |
Target: 10W (MAXN nvpmodel). Use RPLIDAR standby + 640p D435i for compliance.
