In this video we are showing how to provide arguments to a ROS node program made in Python.
Sometimes, when you want to launch a ROS program made in Python, you need to provide some arguments to the program, so it can adapt to your specific requirement of the moment.

In this video, we show how to make an Aibo robot move based on the movement file we provide at launch time to the ROS node.

Please, bear in mind the difference between arguments (what we are teaching in this video) and parameters (that is something completely different handled by the ROS param server) .
