Overview of the Project

This project develops languages and tools to fill the gap between the theoretical and algorithmic advances in reactive synthesis and their practical implementations. An example outcome has been Salty, a domain specific language for GR(1) specifications. Salty makes GR(1) specifications easier to write and debug by supporting features such as richer input and output types, user-defined macros, specification patterns, and specification optimization and sanity checking. Salty interfaces with the synthesis tool Slugs to produce a system design or controller, which Salty implements in a variety of languages. It also interfaces to to freely available unmanned aerial vehicle (UAV) planning and simulation software suites UxAS and AMASE for applications involving coordination of multiple UAVs.
