Robot Operating System (ROS) is an open-source framework designed to help developers create robot software. It provides tools and libraries that simplify the process of building complex robotic systems, allowing for easier integration of various components like sensors and actuators. ROS supports multiple programming languages, primarily Python and C++, and offers a modular architecture. This means developers can reuse code and share their work with the community, fostering collaboration and innovation in the field of robotics. It is widely used in both academic research and commercial applications.
