## What it is
ROS (Robot Operating System) is a meta-operating system providing language-independent, network-transparent communication for distributed robot control systems. This repository holds the core ROS 1 packages, which reached end of life with the final Noetic release in May 2025.

## Use cases
- build a distributed robot control system
- communicate between robot nodes over a network
- control robot hardware with a middleware framework
- maintain a legacy ROS 1 Noetic robot stack
- learn how ROS 1 message passing and node architecture work

## When to choose
- you are maintaining or porting an existing ROS 1 Noetic codebase
- you need to understand ROS 1 internals for migration work
- you have legacy robot hardware that only supports ROS 1 drivers

## When to avoid
- you are starting a new robotics project - use ROS 2 instead
- you need long-term support or security updates
- you need modern features like DDS-based communication or real-time support

## Facets
- artifact type: framework
- maturity: abandoned
- function: middleware, concurrency, sdk
- domain: robotics, microservices
- platform: python, cpp, cross-platform
- tags: robot-operating-system, ros1, end-of-life, robotics-middleware, archived, automation, linux
