SUMMARYGiven the advanced breakthroughs in the field of supportive robotic technologies, interest in the integration of the human body and a robot into a single system has rapidly increased. The aim of this work is to provide an overview of empowering lower limbs exoskeletons. Along with lower exoskeleton limbs, their unique design concepts, operator–exoskeleton interactions and control strategies are described. Although many problems have been solved in recent development, many challenges remain. Especially in the context of infantry soldiers, fire fighters and rescuers, the challenges of empowering exoskeletons are discussed, and improvements are outlined and described. This study is not only a summary of the current state, but also points to weaknesses of empowering lower limbs exoskeletons and outlines possible improvements.

The revolution in systems autonomy is underway. We are at the dawn of a radical change in the use we make of the equipment available to us, with the upcoming and progressive autonomy of this equipment allowing it to adapt to the situation. The danger and complexity of the military world makes it difficult to anticipate the major issues linked to the adoption of these machines, in particular that of the responsibility of the leaders who will allocate their tasks or missions, as well as that of those who design and test these systems. This chapter proposes to list some of the safeguards necessary for their use: the control of these systems by leaders, the necessary confidence in their use and the need to integrate into their embedded software rules to be respected when tasks are executed (rules of engagement linked to the circumstances, or standards not to be violated). It emphasises the absolute role of leaders whose choices must, at all times, prevail over those of AIs, especially in complex situations, and who must ensure the conduct of the manoeuver because they are the guarantor who gives meaning to military action.

Les systèmes robotiques militaires évoluent vite grâce aux progrès technologiques et au développement de l’Intelligence artificielle. Leur degré d’autonomie va s’accroître, posant la question centrale de leur contrôle, avec celle de la place de l’homme dans le processus décisionnel allant jusqu’à l’ouverture du feu.
