The complexities of mechanical design in the development of a prosthetic hand are thoroughly examined in this thesis. The index finger is used as a standard to emphasize the standardization of finger design. Thorough Finite Element Analysis (FEA) is carried out to guarantee the prosthetic hand's robustness to varying loads. After that, the finger is subjected to a thorough kinematic analysis that treats it as a dual 4-bar mechanism and offers a complete understanding into its dynamic behaviour, velocity, and location over time. The assembly procedure is analysed in detail together with material selection criteria that prioritize PLA to highlight the strength and practicality of the mechanical design. The investigation additionally extends its scope to include sensors and a control system, with servomotors and electromyographic (EMG) signals being the main type of integration.

The functionality of the prosthetic hand is improved by the ensuing integration. Thorough validation using SimScape Multibody produces outcomes that confirm the system's correct operation and careful attention to its mechanical components.
