Hi, I'm learning ROS and trying to create a program that manages the whole application by monitoring the nodes, services, check if everything is working, if not restart the one that failed. But I'm a little bit confuse about nodes and services. So if a node fails, does it mean the service associate with that service also fail? If I restart the node, does the service also restart? Is the same if the service fails?
In ROS, services are 'only' means of communication. Not to be confused with a cloud-service or something. When node A, calls a service of node B, whatever runs in the service is executed by node B and the result is passed back to A. https://wiki.ros.org/rospy/Overview/S...
Thank you for your answer. So, that means if I restart the node, the service associate with it will be restart as well?
