Abstract
The research focuses on design and simulation of a powered ankle foot prosthesis with for below knee amputation. A prosthesis is an artificial device that replaces a missing or injured part of one’s body. The purpose of this research is the development of service and assistive robotic prosthesis that can be used by amputated people in everyday environments to obtain a natural gait. So, it should be designed and assembled per the patient's cosmetic and functional needs. This work addresses the problem of below knee amputation. A working model with all parts of the prosthesis are designed individually and assembled together using Solid Works®. Since the power transmission to the foot and movement control is directed through the actuator, it is very important to design an actuator which fulfills all the vital parameters required for the prosthesis to work effectively, i.e. weight, torque and speed. By varying the properties of materials used for manufacturing and different specifications of the actuator. The presented design has been validated using finite element analysis (FEA) on ANSYS®.
