This dissertation aims to design and manufacture an externally powered prostheses that closely replicates human hand movement, enhancing amputee comfort and mobility. The work involves four main stages: the design using SolidWorks, structural analysis with ANSYS Workbench, manufacturing via CNC and 3D printer, and the design of Arduino-controlled electronic system to regulate the movements of hand prosthesis. The mechanical components of the prosthetic hand comprise the phalanx, links, linear actuator, servomotor, bolts and palm. The phalanx are designed and manufactured from aluminum, while links are manufactured from stainless steel 304.
The Dissertation included recommendations including:
- Logic control system is used to regulate the movements of fingers and thumb by fuzzy logic controller.
- The measurements of MyoWare and FSR sensors are inputs into the prosthetic hand, where these data used to control for the voltage of linear actuators, and servomotor by fuzzy logic controller.
- The design and testing electromyography prosthetic hand suggest it is a practical and innovative solution for upper limb amputees, offering improved adaptability compared to traditional prosthetic hand designs.
After the scientific discussion by the members of the discussion committee, the researcher received a rating of (Very good).
