Ros is a programming language designed for robotics and automation. It stands for Robot Operating System, but it is not an operating system in the traditional sense. Instead, it provides a framework for writing robot software, offering tools and libraries that simplify the development process. Ros enables communication between different parts of a robot's system, allowing them to work together efficiently. It supports various programming languages, including Python and C++, and is widely used in both academic research and industry for building complex robotic applications.
