 When the launch file is running, a simulation with a graphical user interface opens.
-The launch file also contains a node that can be used to send keyboard movement messages to the robot. you need to click on the terminal that you opened the launch file and use arrow keys to move the turtlebot1. Then you can see that the second turtlebot will follow the first one.

 ===== RViz =====
-Short for ROS Visualization. It’s a 3-dimensional visualization tool for ROS that helps to visualize what the robot seeing and doing. To run the RViz for the the turtlebot simulation there is a predefined configuration file that you can run it with the following command:

-As you can see there are three different transformation frame (tf) in the environment that each represents an element. The world is defined for the environment and turtle1 and turtle2 are for the robots. These transformation frames are useful for positioning and localization.

-When the command is executed, the graphical user interface opens. Robots with complex tasks usually have many different nodes working on them that interact with a variety of topics. It is difficult to see the big picture from the command line and this is done using the //rqt_graph// program. Let's see how it works using the //rqt_graph// tool, which visualizes the relationships between nodes and themes:

 ===== Rqt_plot =====
-The //rqt_plot// tool is used to visualize the subject data over time. With this tool you can display the values of the messages as a graph. This tool can be used, for example, to visualize sensor values. Turtlesim simulator publishes the x and y coordinates of a robot in ///turtle1/pose/x// and ///turtle1/pose/y//. Let's try to display these topics on the graph.
