[ROS in 5 mins] 041 - What is rqt_graph

Hello Everyone

In today's video we're going to see what is rqt_graph and how to use it.

For that we're going to use Robot Ignite Academy, which is the best tool if you want Learn ROS Fast: http://www.theconstructsim.com/construct-learn-develop-robots-using-ros/robotigniteacademy_learnros/

Before we start, if you are new to ROS, I highly recommend you to take any of the following courses on Robot Ignite Academy:

▸ ROS Basics In 5 Days (Python) - http://www.theconstructsim.com/construct-learn-develop-robots-using-ros/robotigniteacademy_learnros/ros-courses-library/ros-basics-in-5-days/
▸ ROS Basics In 5 Days (C++) - http://www.theconstructsim.com/construct-learn-develop-robots-using-ros/robotigniteacademy_learnros/ros-courses-library/ros-courses-ros-basics-in-5-days-c/


The commands used during the video were following:

rostopic pub /news std_msgs/String "data: 'Welcome to ROSCon 2018'" -r1 __name:=news_pub

rostopic echo /news __name:=news_sub

rosnode list
rosnode info /news_sub
rqt_graph

We love feedback, so, whether you like the video or not, please share your thoughts on the comments section below.

Thanks for watching.
