The **Robot Operating System (ROS)** is an open-source, flexible framework for building and managing robotic applications. It offers tools, libraries, and conventions that simplify robot software development. Widely used in research and industry, ROS supports tasks like robot navigation, perception, and manipulation, enabling the creation of intelligent, autonomous systems across healthcare, manufacturing, defense, and service industries.

2. Introduction
to Robot
Operating
System
(ROS)
● ROS stands for Robot Operating System.
● It’s an open-source, flexible framework for writing robot software.
● ROS provides tools, libraries, and conventions for robot
development.
● It is not an operating system but a middleware running on a host
OS.
● ROS helps control robots by handling hardware abstraction and
low-level device control.
● It simplifies complex robot behaviors through modular
programming.
● Developed originally at Willow Garage in 2007.
● Widely used in academia and industrial robotics R&D.
● Supports multi-language programming like C++, Python, and Lisp.

ROS Architecture Overview :
● Consists of Nodes, Topics, Services, and Actions.
● Nodes are independent programs performing tasks.
● Topics are named buses for asynchronous communication.
● Services enable synchronous request-response actions.
● Actions manage long-running tasks with feedback.
● Uses a Master Node to track nodes and topics.
● Parameter Server stores configuration and parameters.
● Message-passing mechanism is highly scalable.
● ROS runs on Linux-based OS like Ubuntu.
