In the preceding section, we learned about the basic concept and terminology required to start with the ROS computational network framework. Subsequently, in this section, we will focus mostly on the practical aspect.
Learning working with ROS
Getting ready
Before running any ROS nodes, we should start the ROS master and the ROS parameter server. We can start ROS master and the ROS parameter server using a single command called roscore, which will start three programs by default; ROS master, ROS parameter server, and rosout logging nodes.
