Design and Control of Medical Prosthetic Hand Using Electromyography for Easy Hand Gesture

Abstract

Losing a finger can have a profound impact on a person's mental and physical well-being, making it an incredibly difficult situation. In order to address this challenge, a microcontroller or computer can process verbal commands from the user, analyzing and translating them into actions that the prosthetic hand can perform, such as gripping, holding, releasing, and fine motor skills. This technology has the potential to greatly improve the quality of life for amputees, as it will make the prosthetic hand more natural and intuitive to use. To achieve this, the design of the hand is inspired by the human musculoskeletal system, allowing for flexible and lifelike movements in both a prosthetic hand and a humanoid robot hand. A bioinspired controller was created using 3D printing technology to operate a five-fingered robot hand and its mechanical parts. Additionally, sensors were utilized to detect muscle impulses and control hand movements.
