Jetson Orin Nano Super — AI/SLAM Platform Setup
Self-balancing robot: Jetson Orin Nano Super dev environment for ROS2 Humble + SLAM stack.
Stack
| Component | Version / Part |
|---|---|
| Platform | Jetson Orin Nano Super 8GB |
| JetPack | 6.x (L4T R36.x, CUDA 12.x) |
| ROS2 | Humble Hawksbill |
| DDS | CycloneDDS |
| SLAM | slam_toolbox |
| Nav | Nav2 |
| Depth camera | Intel RealSense D435i |
| LiDAR | RPLIDAR A1M8 |
| MCU bridge | ESP32-S3 BALANCE (CAN bus @ 500 kbps via CANable 2.0) |
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) | ~19.9W |
| Peak | ~28.2W |
Target: 25W (MAXN nvpmodel). 5W headroom at nominal load.
