An improvement to the current design of the robotic hand exoskeleton
will need a more detailed design, which will result in higher precision and
accuracy for the seniors to perform certain tasks. The metallic fingertips on
the exoskeleton were too slippery for the electric toothbrush and deck of cards.

A rougher material with more grip for the tips will solve this problem. A
possible solution is small rubber pads on the tips of the hand to allow for
more traction.

To improve the current design, installing the metallic aluminum rings
to the joints of all the fingers (middle, ring, and pinky) will allow for more
accuracy and the seniors would then be able to perform a grabbing motion
instead of a pinching motion. This will also solve the problem of the slippery
objects because the senior individual will be able to grab the object, rather than to pinch it. With this design, the
senior can pinch the object but will be capable of grabbing it as well.

Another adaption to this design would to use a lighter battery and
pump pneumatics, which are needed to aid the seniors in a more comforting way. Having
heavier equipment makes it more difficult for the senior individual to carry
around in their wheelchair. To increase the assistance of this robotic hand,
the battery and pneumatics should be considered to have lighter weighted
material. The materials need to be appropriate technology, in which it would be
cost efficient and would use local materials. To improve this design, the sensors should be able to read EMG and
EEG signals that are of smaller sizes to increase the range of seniors that
would be able to use this product. In case some of the biceps are also injured
or not responsive, the magnification on the EMG and EEG signals will help in
those scenarios. This can be done by increasing the wavelength  

Based on the tests, the individual was tested to lift objects that
were all less than one pound in mass. To improve this design, the robotic hand
exoskeleton should have a stronger carrying capacity of approximately 8 lbs. This
can be done by putting a greater flexion on the hand to allow for higher massed
objects. Another adaptation to this current design would be to increase the
size of the metallic fingertips, so the chance of the object being slipped out
is minimal.
