Abstract—Wearable robots, such as exoskeletons, interact
closely with the wearer. To this end, mechanical features
are combined with control techniques to transparently follow
human movements. Such expected behaviour depends on special
project requirements, safety being the most critical one.
According to the literature, the modular robot design approach
provides flexible and yet robust solutions that meets stakeholder
requirements.
The semi-formal design approach has been exploited by
the scientific community to specifically focus on requirements
definition. In this perspective, Goal Oriented Requirement
Engineering (GORE) has been used as a tool for different
systems; however, it has been more widely adopted in software
rather than in hardware engineering.
