Introduction
===============

In this workshop, you shall deepen your ROS2 knowledge by creating a ROS2 package
and a ROS2 node on your own.

Task: ROS2 package
===================

Create a package called **hello_world** inside your workspace *robot_ws*.

Task: ROS2 node
================

Create a node named *hello_world.py* inside the **hello_world** package. 
The task of the node is to continously print to terminal with a delay
of 1 second. The output to the terminal should be:

1. “Hello ROS2 World!”
2. Counter for the current number of prints.

Task: Parameters
==================

Modify the existing node to implement two parameters:

1. freq → change the rate at which the text is displayed
2. text → change the text that is displayed

Task: Launch file
===================

Write a launch file to perform the following tasks:

1. Start the *hello_world.py* node.
2. Set different parameter values for:

  - freq → rate at which the text is displayed
  - text → text that is displayed
