It is an open-source platform used for developing the software of robotic systems. Its primary aim is to provide modular and reusable software components for robots, enabling robotic projects to be developed more quickly and effectively. ROS facilitates the integration of different robots' sensors, motors, and other hardware components, allowing for easier programming of complex tasks.

Autonomous robots are systems that can perceive their environments, make decisions, and move independently. ROS plays a crucial role in the development of these robots. For example, all the components necessary for an autonomous robot to detect obstacles in its environment, plan its path, and move safely can be integrated using ROS. Additionally, ROS accelerates the development process by enabling robots to be tested in real-world or simulated environments.
