The very first application of active exoskeleton robot was to provide external power to a
soldier so that he can carry additional weight than his strength. Since then this technology
has focused on developing systems for assisting and augmenting human power. Later this
technology is expanded into other applications such as limb rehabilitation and tele-
operations. Exoskeleton research is still a growing area and demands multi-disciplinary
approaches in solving complex technical issues. In this paper, the developments of active …
