In this paper, we describe some of our insights with respect to robot control architectures and robotics software systems engineering. The focus of the paper is not on discussing specific functionalities but to explain some best practices that evolved out of our experience in building complex software intensive robotic systems. These behind-the-scenes insights are in particular relevant in moving forward towards a robotics business ecosystem with separation of roles and based on model-driven approaches for handling systems of systems.enText/Conference Paper1617-5468
