ROS Tutorial for beginner: create your first Subscriber Node in ROS (Robot Operating System) Kinetic . I will guide you step by step, showing how to select a standard message and to debug your code using RQT_GRAPH.

We refer to the Subscriber built in this video: youtu.be/uip2BbaazjU

*** Follow the whole series: youtube.com/watch?v=N6K2LWG2kRI&list=PLuteWQUGtU9BU0sQIVqRQa24p-pSBCYNv

We build a Subscriber node in python, sharing a simple string message (std_msgs/String). Then we compile the package with catkin_make and use "chmod" for making the file executable. Finally we source the development environment and we run the node.

At last we check that everything runs smoothly using RQT_GRAPH
