The main advantage of exoskeleton is the mobility of the user. Thanks to the rapid development of technologies and the attention paid by manufacturers to their adaptation to work situations, exoskeletons are more and more easily integrated into various activities, particularly in the context of prolonged postural support, repetitive movements or carrying loads
Technologies evolve rapidly and we observe the appearance of two types of exoskeletons:
"Active" exoskeletons: equipped with electronic components for controlling, retrieving and processing information, requiring batteries and therefore limited autonomy. These exoskeletons easily adapt to different types of activities, even the most complicated. However, they are heavier, more expensive and less reliable than passive exoskeletons.
"Passive" exoskeletons only work on mechanical concepts, so their autonomy is not limited. These technologies are less expensive and allow a perfect response to a specific work activity. We equip ourselves easily and quickly. The major drawback of these exoskeletons is their technical specificity : a passive exoskeleton relieves a specific movement or position but can disrupt other movements, it must be ensured that it will be perfectly adapted to the chosen activity.
There are not many robotic (or active) exoskeletons, we can see their appearance in the medical sector while mechanical exoskeletons are intended for industrial sectors for prevention.
