Prosthodontic design with two degrees of freedom

Throughout the whole human history, loss of limbs has been an important issue, such that extensive research has been conducted in designing and controlling above-knee prostheses, which have a long history of application by humans. Over time, with advances in medical sciences and engineering, this auxiliary tool evolved and has always been improving. Nevertheless, some challenges have remained. Therefore, proper and optimal design of knee mechanism for those who are not able to move can be very useful. To achieve this aim in the best way, various mechanisms have been analyzed by scientists, culminating in designing different mechanisms with various practical potentials. In this way, people given their conditions including their job and extent of movement can benefit from these mechanisms.In this research, first mechanical maps will be plotted. Thereafter, using kinematics, equations of motion of the prosthesis will be obtained. After that, prosthesis will be controlled, where the data obtained from rehabilitation center of Dr. Movafaghian will be transferred to micro-prosthesis section, followed by computations. Eventually, the output of prosthesis data will be validated against the received data.
