Diseño y construcción de un prototipo de prótesis biónica de antebrazo y mano con control difuso

Abstract

This research focuses on an innovative approach to the development of a bionic hand and forearm prosthesis. The primary objective of this thesis is to create a device that harnesses fuzzy control technology and employs components such as servomotors in conjunction with an Arduino controller. This prosthesis is designed to dynamically adapt to the user's Electromyographic (EMG) signals, enhancing natural control and user experience. The research process begins with a comprehensive analysis of existing prostheses, both in scientific development and the commercial market. Relevant data and technical specifications are collected to establish a solid foundation for defining essential prototype features. Subsequently, alternative selection is carried out using a decision-making approach supported by the Quality Function Deployment (QFD) methodology. In a later stage, in-depth mathematical analyses encompassing structural stress evaluations are conducted. Once the dimensions of the structure and necessary electronic circuits are established, the physical construction of the prototype, along with the integration of the controller, takes place. This marks a significant milestone in the research as the device takes shape and prepares for testing. To assess the performance of the prosthesis prototype, a testing protocol is implemented, focusing on ensuring that the initial technical specifications are met under real-world usage conditions. This process is crucial for validating the effectiveness and reliability of the device.
