  The upper limb robotic exoskeleton is an electromechanical device which use
to recover a patients motor dysfunction in the rehabilitation field. It can
provide repetitive, comprehensive, focused, positive, and precise training to
regain the joints and muscles capability. It has been shown that existing
robotic exoskeletons are generally used rigid motors and mechanical structures.
Soft robotic devices can be a correct substitute for rigid ones. Soft exosuits
are flexible, portable, comfortable, user-friendly, low-cost, and
travel-friendly. Somehow, they need expertise or therapist to assist those
devices. Also, they cannot be adaptable to different patients with
non-identical physical parameters and various rehabilitation needs. For that
reason, nowadays we need intelligent exoskeletons during rehabilitation which
have to learn from patients previous data and act according to it with patients
intention. There also has a big gap between theoretical and practical
applications for using those exoskeletons. Most of the intelligent exoskeletons
are prototype in manner. To solve this problem, the robotic exoskeleton should
be made both criteria as ergonomic and portable. The exoskeletons have to the
power of decision-making to avoid the presence of expertise. In this growing
field, the present trend is to make the exoskeleton intelligent and make it
more reliable to use in clinical practice.
