Controllable Bionic Hand Design

Bionic hand is a system consisting of many electronic and mechanical parts. Motion in the bionic hand system is achieved by motor control. One of the most complex organs of the human body is the hand. Bionic hand design has been studied in engineering and biomedical fields in recent years. There are different clutch and stance situations in 24 degrees of freedom, 4 of which are passive. Bionic hand clutching process is carried out by tendons attached to the joints, muscles and the stimulus nerves. Human hand is sufficient for meeting a large part of human activities in daily life with five-six different movement. These movements are hand and hand concepts which can be called hook, sign, key grip, cylinder grip. In this study, a moving bionic hand consisting of wrist and five fingers was designed using three-dimensional printer technology and flexibility sensors instead of the existing classic immobilized prosthetic hand in order to facilitate the lives of disabled people who were born or lost one limb. Flexibility sensors are used in the design. With the help of these sensors, bionic hand control, which can be controlled by human hand position information, has been realized. The data perceived from the angular movements of the fingers of the human hand are processed by a controller and bionic hand control is provided by means of servo motors. Thus, the designed bionic hand was made to perform human hand movements with gloves. In addition, the designed bionic hand can also be used in automation for remote control of handling in hazardous environments and places where it is unsuitable for human health and safety.
