Hello,

I am looking for a possibility to start a non-ROS program in ROS2 with a launchfile. For ROS1 there is aliencontrol. Is there something like this for ROS2? Or is it possible to start external programs from the Python launchfile?

Thank you! Jan

Take a look at the ExecuteProcessAction (https://github.com/ros2/launch/blob/m...)

In fact, the Node Action you're probably already using in the python launch script wraps ExecuteProcess.

ExecuteProcess(cmd=['ping', '192.168.1.1'],
               output='screen'),

Concrete example that uses ExecuteProcessActioncan be found in the official tutorial https://docs.ros.org/en/rolling/Tutor...
