  Engineering software for robotics applications requires multidomain and
application-specific solutions. Model-driven engineering and modeling language
integration provide means for developing specialized, yet reusable models of
robotics software architectures. Code generators transform these platform
independent models into executable code specific to robotic platforms.
Generative software engineering for multidomain applications requires not only
the integration of modeling languages but also the integration of validation
mechanisms and code generators. In this paper we sketch a conceptual model for
code generator composition and show an instantiation of this model in the
MontiArc- Automaton framework. MontiArcAutomaton allows modeling software
architectures as component and connector models with different component
behavior modeling languages. Effective means for code generator integration are
a necessity for the post hoc integration of applicationspecific languages in
model-based robotics software engineering.
