ROS2 Include Launch Files

Hard Advanced Launch 58% pass rate
#launch#include#modular#composition

Practice the ROS2 Include Launch Files coding problem in Advanced Launch. Browser-based execution with automated grading — no local ROS install required. 58% of engineers pass this challenge.

Problem Statement

Build complex systems by including other launch files. This allows for modularity (e.g., including nav2_bringup inside your robot_bringup).

Requirements

  • Include a launch file named other.launch.py from package other_package
  • Pass an argument my_arg:='value' to the included file

Input/Output Format

Output:

  • LaunchDescription with IncludeLaunchDescription

⚠️ Common Pitfalls

  • Syntax around PythonLaunchDescriptionSource (it takes a path string).
  • Passing arguments requires launch_arguments={'key': 'val'}.items().
