What it does

  • Wraps frequent launch patterns such as nodes, included launch files, namespaces, and conditional groups into short one-line calls.
  • Handles launch arguments, letting arguments be declared and retrieved as plain Python values, including inside OpaqueFunction setups.
  • Provides helpers for calling services and setting parameters at launch time.
  • Offers composable node containers and event-based groups that start actions after a node starts or exits.
  • Includes robot_state_publisher, joint_state_publisher, and RViz helpers.
  • Adds Gazebo tools: launching the simulator, spawning models, saving the world, and building topic bridges.
