sl-jetson c47ac41573 feat: Jetson Nano platform setup and Docker env (bd-1hcg)
- Dockerfile: L4T R32.6.1 (JetPack 4.6) base + ROS2 Humble + SLAM stack
  (slam_toolbox, Nav2, rplidar_ros, realsense2_camera, robot_localization)
- docker-compose.yml: multi-service stack (ROS2, RPLIDAR A1M8, D435i, STM32 bridge)
  with device passthrough, host networking for DDS, persistent map volume
- docs/pinout.md: full GPIO/I2C/UART pinout for STM32F722 bridge (USB CDC +
  UART fallback), RealSense D435i (USB3), RPLIDAR A1M8, udev rules
- docs/power-budget.md: 10W envelope analysis with per-component breakdown,
  mitigation strategies (RPLIDAR gating, D435i 640p, nvpmodel modes)
- scripts/setup-jetson.sh: host one-shot setup (Docker, nvidia-container-runtime,
  udev rules, MAXN power mode, swap)
- scripts/build-and-run.sh: build/up/down/shell/slam/status helper

# 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
```bash
# 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
```
## Docs
- [`docs/pinout.md`](docs/pinout.md) — GPIO/I2C/UART pinout for all peripherals
- [`docs/power-budget.md`](docs/power-budget.md) — 10W power envelope analysis

## 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.
See [`docs/power-budget.md`](docs/power-budget.md) for full analysis.
