🎥 RealSense ROS for Jetson Nano (Ubuntu 20.04)

This repository is a working fork of the official Intel RealSense ROS repo, pinned to the correct branch (tag 2.2.18) for compatibility with our setup.

It goes beyond a plain fork by including everything you need to get Intel RealSense cameras running smoothly on a Jetson Nano with Ubuntu 20.04:

✅ Correct ROS wrapper (2.2.18)
✅ Matching librealsense version (2.39.0) with CUDA support
✅ Prepackaged firmware — the right one to flash onto your camera
✅ Handy bash script to download, build, and install the right stack in one go
