ROS services

ROS services are like a request-and-reply system within robotics software. They allow different parts of a robot or program to communicate by sending a specific request to perform a task and waiting for a response. Think of it as calling a customer service number: you ask for information or action, and the service provider responds with the answer or result. This structured communication helps coordinate complex operations, ensuring components work together smoothly and reliably, especially when an immediate answer or confirmation is needed.
