ROS
ROS (Robot Operating System) is an open-source middleware framework for developing robot software. It provides a collection of tools, libraries, and conventions to simplify the task of creating complex and robust robot behavior across a wide variety of robotic platforms. It is not a traditional operating system but rather a meta-operating system that runs on top of existing OSes like Linux.
Developers should learn ROS when building or programming robots for applications such as autonomous navigation, manipulation, perception, and simulation. It is essential for robotics research, industrial automation, and academic projects because it offers standardized communication protocols, hardware abstraction, and a vast ecosystem of packages. Use cases include developing drones, self-driving cars, robotic arms, and mobile robots.
