ABSTRACT = {Context. The Robot Operating System (ROS) is the de-facto standard for robotics software.However, ROS-based systems are getting larger and more complex and could benefit from good software architecture practices.Goal. We aim at (i) unveiling the state-of-the-practice in terms of targeted quality attributes and architecture documentation in ROS-based systems, and (ii) providing empirically-grounded guidance to roboticists about how to properly architect ROS-based systems.Method. We designed and conducted an observational study where we (i) built a dataset of335 GitHub repositories containing real open-source ROS-based systems, and (ii) mined the repositories to extract and synthesize quantitative and qualitative findings about how roboticists are architecting ROS-based systems.Results. First, we extracted an empirically-grounded overview of the state of the practice for architecting and documenting ROS-based systems. Second, we synthesized a catalog of 47architecting guidelines for ROS-based systems. Third, the extracted guidelines were validated by119 roboticists working on real-world open-source ROS-based systems.Conclusions. Roboticists can use our architecting guidelines for applying good design principles to develop robots that meet quality requirements, and researchers can use our results as evidence-based indications about how real-world ROS systems are architected today, thus inspiring future research contributions},
