TESTING
This is a senior level engineering project. The goal of this project is to design a device that helps
the disabled people. This device will be suitable for both people with moving disabilities and
people having weak muscles, which make them unable to move .Our focus was to make the
device safe to avoid any misuse of equipment that can lead to serious injury. It helps
approachability of the art to the disable people in an easier way. The shape of the device makes
it more stable and leaves fewer chances for any mishap. We have tried our best to make it as
comfortable and feasible as possible. The legs are indispensable limbs for the human being, to
be able to move from one place to another, to carry out sports activities, or simply to walk,
however it is very common that people are exposed to unfortunate situations like automobile,
labor or any other type of accident.
9. CONCLUSIONS
Our design is simple yet efficient. Since assistive device often are a frame in the rehabilitation
process, the need for a better understanding in the prescribing process, use and utility of
assistive devices is of utmost interest to the profession. There are a lot of unanswered questions
in the field and one should benefit from more studies dealing with both user experiences and
underlying factors making a difference in outcome. n this research the parameters of the
gait and the variables of the lower limb that will be fundamental to develop the
exoskeleton in the physical part as in the mechanical part were analyzed. Also, the
flexion / extension angles of each of the joints were obtained, which can be used to
control the mechanism.
9.1 Contributors to Project Success
All of group members were supportive and hardworking. Everyone’s contribution is highly
appreciable. For the project to reach a successful conclusion we need to be working well
together for a common purpose. Leading a team successfully involves learning about each
individual’s skills and personality in order to get the best as a whole. Our team is having a
complete package of an organizer, communicator, leader and a creative thinker and I think
we can well maintain project composure.
9.2 Opportunities/areas for improvement
The design is perfect until now but it can be further improved later on integrating more ease
and designing. The more it is comfortable perfect it becomes. Future improvement is
contemplated for the device, they includes that the device can be modified in a way where
the person can use it even by laying on his bed. Moreover the implementation of the
control for the system through motors, which must be able to generate the same
angles that are formed in the running cycle with variations in the frequency of
execution because the device will be used to rehabilitate patients with some physical
or motor limitation. This will be more feasible for the disabled people. This will help those
ones too who are unable to sit due to some spinal cord or backbone injury.
