# 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
|
|
```

## 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.
