Experience with a Model-based Safety Analysis Process for Autonomous Service Robot
Résumé
Safety is a major concern for autonomous systems that physically interact with humans, such as service robots. However, modeling dynamics of such systems is hard so classical safety analysis methods need to be adapted. In this paper, we propose an approach based on a combination of well-known safety analysis techniques. We propose to describe scenarios of use with the common Unified Modeling Language. Risk analysis is then performed using a Preliminary Hazard Analysis, an adaptation of the HAZOP method and the classical Fault Tree Analysis. This paper explains the overal process and illustrates it through the exemple of the MIRAS projects which aims to develop a robotic strolling assistant that will help disabled persons to stand, sit and walk.
