ABSTRACT
In recent times, "service robotics" and more especially medical robotics, have evolved considerably. This rapid development now raises the issue of security. Indeed, human-environments that feature the interaction of humans and robots present a number of challenges; therefore the designers have had to incorporate the requirements of dependability and security into their studies. After a brief summary of the concept of security in the field of robotics, this article details the damage, hazard (dangerous phenomenon, damaging event, accident and incident), and the resources in place to manage this risk. To conclude, the security assurance is reviewed alongside certification and risk approaches, and the classification of medical devices.

INTRODUCTION
The use of robotic systems in the medical field began a few years ago, and poses the problem of safety in an environment where humans are very much present. The complexity of such systems, and the transfer of responsibilities from the surgeon to the robot, have led designers to integrate operational safety requirements into their studies, and in particular one of its essential attributes: safety. Although this discipline is widely studied in safety-critical fields such as avionics, the specificity of medical robotics leads us to reconsider the associated notion of risk. Starting from the undesired effect, the damage, we go back to the causes, considering the notions of danger, risk and safety. This leads us to identify possible ways of managing the risk associated with the use of medical robotics systems. The concepts introduced are illustrated by our experience in developing a tele-echograph robot.
