Navigation & SLAM

Nav2

Nav2 is the standard open-source navigation framework for ROS 2, succeeding the original ROS navigation stack built around move_base. It uses behavior trees to orchestrate planner, controller, smoother, and recovery servers over layered costmaps, providing global path planning and local trajectory control for mobile robots. Nav2 is widely deployed on autonomous mobile robots, service robots, and research platforms.

Why it matters for physical AI

Mobile manipulation and fleet deployments need dependable point-to-point navigation; Nav2 provides a production-tested baseline so teams can focus learning efforts on manipulation and higher-level autonomy.
