This repository contains documentation and tools for getting started with NEPI Engine, a full-featured edge-AI and automation software platform for NVIDIA Jetson and other embedded edge-compute hardware platforms.
NEPI Engine runs on lots of embedded Linux devices, though certain hardware and O/S configurations are more well-suited than others. In general, NVIDIA Jetson platforms are well tested and supported. The scripts and documentation in this repository are tailored for modern Debian-based Linux distributions (e.g., Ubuntu 18.04+); if that is not your situation, then NEPI may still be appropriate wholly or in part, albeit with additional setup legwork.
Numurus provides commercially licensed pre-built root filesystem images and turnkey processing hardware solutions for select platforms -- speed up your development time considerably by exploring one of these options. Or contact us to discuss professional support options for other platforms
The following sections describe the architecture of the NEPI Engine and provide tools and guidance for getting NEPI running on your device.
A NEPI-enabled device provides the complete NEPI Engine suite of tools and applications. Most of these components can be enabled and disabled through system configuration, and many can also be started and stopped at run-time as needed.
NEPI Engine setup and source code is distributed across two top-level repositories:
- nepi_engine_ws - Superproject for all NEPI Engine source code, including hardware drivers, ROS-based SDK components, user interfaces, and edge-side NEPI Connect components. Source code is organized as a collection of git submodules below this superproject. Building and running this software depends on a properly prepared root filesystem, as covered by nepi_rootfs_tools.
Some other stand-alone repositories may be useful depending on your needs
-
nepi_ros_interfaces - Collection of NEPI Engine custom ROS messages and services. Included as part of nepi_engine_ws, but if you are only trying to interact with an existing NEPI Engine system via the ROS interface, this repository can be included in your own workspace, built, and sourced to provide these message and service objects to the rest of your application.
-
nepi_sample_auto_scripts - Large and growing collection of NEPI Engine automation scripts that provide useful functionality and examples for the powerful NEPI Engine Automation Manager. Typically these scripts are deployed as-is to the NEPI storage partition (i.e., user partition) and/or used as references when developing new scripts.
The best way to get involved is to contribute to NEPI-Engine source code and documentation.
