Abstract:
The human hand is one of the complex organs in biomechanical perspective, it
consists of 27 skeleton bones and allows up to 30 degrees of freedom (DOF).
Attempts to imitate the human hand movements were very expensive or
cumbersome, so the studies carried out in order to model the human hand motions
have found link between the various joints of finger, the human usually cannot
bend the top joint of the finger without bending the joint next to it.
Using this knowledge the model is built, that allows 15 degree of freedom related
to each other and therefore can be activated using 6 actuators only.
The hand gesture controlled bionic hand is a project which can be used in many of
applications, it use as humanoid robotic hand to train the hands of those who suffer
from weakness of the muscles of their hands as a result of amputation or as a result
of a stroke which in this case is used as a support structure for rehabilitation,
treatment by using right hand to help improper hand and in the places unsafely of
human which exist in it and as surgical arm.
The project includes the idea of sending signals from normal hand which contain
many of sensors into bionic hand which simulate normal hand in some movements
by using wireless technology where contains actuators and these operations are
controlled by using microcontroller.
There are humanoid robots which mimic many of the human movement( face, arm,
legs, eyes and so on), in this project the goals have been dramatically increased to
design a bionic hand which mimic the normal hand in rotational motion of wrist
and flexion and extension of fingers.
