Establecimiento de un sistema de control por medio de señales mioeléctricas para una prótesis de mano

Abstract

This project highlights the importance of applying areas such as automation and control for a Mechanical Engineer, since the development of this knowledge has led to progress in other branches of Mechanical Engineering allowing the improvement of daily work in teams supporting the fields of design, production and processing of raw materials in the thermal industry, bioengineering and robotics. For this reason, Universidad Santo Tomás has implemented several projects focused on technology in recent years, among them the design and programming of prostheses is weighted, where advances such as the project entitled 'Implementation of a control system through myoelectric sensors for a transradial arm prosthesis', which consisted in the manufacture of a prototype of transradial prosthesis controlled by myoelectric signals by an Arduino card in a wired way [1]. Subsequently, a breakthrough called 'Development of a control system for the movement of a prototype hand prosthesis from the recognition of myoelectric signals', which consisted of making a modification of the arm performing the design wirelessly by means of the Raspberry Pi 3 B+ card [2]. However, the developed prosthesis takes several seconds to receive orders and execute the necessary movement; in addition, the control system is saturated, i.e. it stops working continuously and reliably generating that the program needs to be restarted. Therefore, this project aims to implement a control system for a hand prosthesis using myoelectric sensors and developing a totally wireless communication, improving the processing and avoiding data congestion, so that it can replicate five basic hand movements necessary for a person and improving the reliability of the system.
