Here's the condensed version of what's going on: Initialize the ROS system ; Advertise that we are going to be publishing std_msgs/String messages on the chatter topic to the master . Loop while publishing messages to chatter 10 times a second . Now we need to write a node to receive the Sleeps for any leftover time in a cycle. Calculated from the last time sleep, reset, or the constructor was called. ros::spinOnce(); loop_rate.sleep(); ++count; ros::spinOnce() is analogous to the main function of the ROS framework. Whenever you are subscribed to one or many topics, the callbacks for receiving messages on those topics are not called immediately. Instead they are placed in a queue which is processed when you call ros::spinOnce()

Sets the start time for the rate to now. bool, sleep (). Sleeps for any leftover time in a cycle. Calculated from the last time sleep, reset, or the constructor was called The ROS way of doing this is: rate = rospy.Rate(1) # 1 Hz # Do stuff, maybe in a while loop rate.sleep() # Sleeps for 1/rate sec. Or the similar: ros::spin() and ros::spinOnce() are resposible to handle communication events, e.g. arriving messages. If you are subscribing messages, You just create a ROS Rate with a given frequency in your code, and use the sleep() functionality to wait until the next iteration. ROS Rate is different from a “ simple
Let's create C++ file for your node, name it tutorial_pkg_node.cpp and place it ros::Rate loop_rate(50); while (ros::ok()) { ros::spinOnce(); loop_rate.sleep(); } }.
