What each one is

Nav2

Autonomous navigation · NOASSERTION

Nav2 handles mapping, localisation, path planning and obstacle avoidance for wheeled and legged robots on ROS 2.

  • Complete navigation stack, not just a planner
  • Used in commercial deployments
  • Behaviour trees make the logic auditable

Gazebo

Robot simulator · Apache-2.0

Gazebo simulates robots with their sensors and environment — the classic testing ground before deploying to real hardware.

  • Realistic sensor simulation
  • Tight ROS integration
  • Decades of robotics use behind it
