Configure Jetson Orin with Tailscale client connecting to Headscale coordination server at tailscale.vayrette.com:8180. Device registers as 'saltylab-orin' with persistent auth key for unattended login. Features: - systemd auto-start and restart on WiFi drops - Persistent auth key storage at /opt/saltybot/tailscale-auth.key - SSH + HTTP access over Tailscale tailnet (encrypted WireGuard) - IP forwarding enabled for relay/exit node capability - WiFi resilience with aggressive restart policy - MQTT reporting of VPN status, IP, and connection type Components added: - jetson/scripts/setup-tailscale.sh: Tailscale package installation - jetson/scripts/headscale-auth-helper.sh: Auth key management utility - jetson/systemd/tailscale-vpn.service: systemd service unit - jetson/docs/headscale-vpn-setup.md: Comprehensive setup documentation - saltybot_cellular/vpn_status_node.py: ROS2 node for MQTT reporting Updated: - jetson/systemd/install_systemd.sh: Include tailscale-vpn.service - jetson/scripts/setup-jetson.sh: Add Tailscale setup steps Access patterns: - SSH: ssh user@saltylab-orin.tail12345.ts.net - HTTP: http://saltylab-orin.tail12345.ts.net:port - Direct IP: 100.x.x.x (Tailscale allocated address) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
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.
