Maîtrise de la sécurité des systèmes de la robotique de service - Approche UML basée sur une analyse du risque système

Abstract : Service robot systems, as medical robots, can perform complex tasks and share
their working area with humans. Therefore, they belong to safety critical systems. In nowadays
development process, safety is often managed by the way of dependability techniques. We
propose a new global approach, based on the risk concept in order to guide designers along the
safety analysis of such complex systems. Safety depends on risk management activity, which
core is risk analysis. This one consists in three steps : system definition, hazard identification
and risk estimation. We first propose the use of UML (Unified Modeling Language) as the
description language and we integrate human factors activities for the system definition step.
Then, for the next steps, interactions of UML and risk analysis techniques such as FMECA
(Failure Mode, Effects and Criticality Analysis) and FTA (Fault Tree Analysis) are studied.
As an illustration of its potentiality, the proposed approach is then applied to the case study
of a system for robotic tele-echography (ultrasound scan examination) actuated by artificial
muscles of McKibben.
