## What it is
Nav2 is the industry-standard navigation framework for ROS 2, providing perception, path planning, control, localization, and behavior-tree-based autonomy for mobile and surface robots. It is a production-grade, modular system supporting differential, omni, Ackermann, and legged robots, with extensible plugin-based task servers.

## Use cases
- navigate a mobile robot autonomously around obstacles
- plan paths and compute motor commands for a ROS 2 robot
- build custom robot behaviors with behavior trees
- add obstacle avoidance to a warehouse robot
- migrate from the ROS 1 navigation stack to ROS 2
- develop custom navigation planner or controller plugins

## When to choose
- you are building a mobile robot on ROS 2 and need production-grade navigation
- you need path planning, control, and obstacle avoidance out of the box
- you want a modular, extensible framework with plugin support and professional maintenance

## When to avoid
- your robot is not ROS 2 based
- you need navigation for aerial or underwater vehicles rather than mobile/surface robots
- you want a simple one-off path planner without a full autonomy stack

## Facets
- artifact type: framework
- maturity: stable
- function: robotics, simulation, middleware, plugin-system, developer-tools
