Diseño y construcción de un prototipo de prótesis para amputación transhumeral de dos grados de libertad mediante control de voz y activación por ALEXA

Abstract

The main objective of the curricular integration work was to develop a prototype of a transhumeral prosthesis with two degrees of freedom activated by voice control and Alexa. The prosthesis has two movements: the opening and closing of the hand and its rotation to pronation and supination. Using the anthropometric measurements of one of the authors, an aesthetic and functional prototype was designed that meets the appropriate tolerance and fit measurements. Different CAD, CAM, and CAE software were used where 3D modeling was created, the manufacturing processes were optimized using 3D printers, and the mechanism's kinematic and structural resistance analysis was simulated. Concerning functionality, the prototype was programmed and configured through the use of already existing and free applications to carry out activation through voice control for grasping objects, facilitating the learning of the use of the prototype for users, in addition to allowing them to enter More voice commands customized to your needs. The design and construction of this prosthesis prototype seek to improve the quality of life of people with upper amputations by providing them with basic but essential functionality for the autonomy of users in their daily activities.
