Non-Functional Requirements in Robotic Systems: Challenges and State of the Art

Abstract

The design of the software architecture is driven by two types of requirements: Functional Requirements specify what the software system does, while Non-Functional Requirements (NFRs) express desired qualities, called Non-Functional Properties (NFPs). This paper illustrates three research challenges for addressing NFRs in the engineering process of autonomous robotic systems related to identification, modeling, and analysis of robotic-specific NFRs, reports on partial state-of-the-art solutions currently documented in the literature, discusses possible steps to overcome current limitations.
