CROME: Contract-Based Robotic Mission Specification
Paper in proceeding, 2020

We address the problem of automatically constructing a formal robotic mission specification in a logic language with precise semantics starting from an informal description of the mission requirements. We present CROME (Contract-based RObotic Mission spEcification), a framework that allows capturing mission requirements in terms of goals by using specification patterns, and automatically building linear temporal logic mission specifications conforming with the requirements. CROME leverages a new formal model, termed Contract-based Goal Graph (CGG), which enables organizing the requirements in a modular way with a rigorous compositional semantics. By relying on the CGG, it is then possible to automatically: i) check the feasibility of the overall mission, ii) further refine it from a library of pre-defined goals, and iii) synthesize multiple controllers that implement different parts of the mission at different abstraction levels, when the specification is realizable. If the overall mission is not realizable, CROME identifies mission scenarios, i.e., sub-missions that can be realizable. We illustrate the effectiveness of our methodology and supporting tool on a case study.
