Hello Everyone,
I am trying to learn Path planning course from the ros construct.

Everything is going good but I need to see graphic of the connection of all rosnodes, rostopic and all. The command for graph is “rqt_graph”, as I tried this command in terminal i did not see anything. Could someone please suggest me the right command for showing Graph in Ros Develop Studio.
Thanks in advance.

Hey @ros.MINING,

You need to do the following:

  1. Get roscore running, if not already, in the background:
nohup roscore &
  1. Run rqt_graph:
  1. Open Graphical Tools from the tools menu to see the graph.

thank you so much for your guidence
