The aim of this work is to design a five fingered robotic hand and analyze the various feasible working parameters using computer software, for the betterment of the differently abled person’s needs. Any person who has hand amputee, may face difficulty doing or working livelihood activities. Hence, it is very important to develop prosthetic robotic hand having greater flexibility and controllability. In this paper with the help of ANSYS and CATIA a robotic arm is designed, a material is selected for its fabrication and FEM analysis is performed, which enabled to have a working model and software prototype similar to a generalized human hand, that is competent to perform gripping and holding of objects. There are also provisions for mechanisms that would allow proper movement and precise control of the hand. Also, kinematic analysis was carried out to understand and improve certain design considerations and to ensure that the robotic hand works well within its operating limits. The paper is based on the improvement and simplifications of the design of the robotic arm which were previously developed. It is found that the material that is selected and designed is safe, and stress applied is within elastic limit.
