4. 4. Inizializing ROS

   And to Initialize Rosedep Tool
   This Utility is Required by some Core Components and possibly it make easy to Search for Dependencies on Source Compilation builds.
   To Setup it fire:

6. 6. Testing ROS

   Now it’s Time to Test ROS Setup
   On a Shell Window let the Talker Publishing Messages of “Hello World!”:

   ros2 run demo_nodes_cpp talker

   

   Then Open a New One and see if the Listener is Hearing:

   ros2 run demo_nodes_py listener

   

   You should see the Talker saying that it’s Publishing messages and the Listener saying I heard those messages.
   This verifies both the C++ and Python APIs are working properly.
   Hooray!
