Construción de un prototipo exo-esqueleto para rehabilitacion de la mano: manufactura de impresión 3D del exo-esqueleto de la mano y valoracion funcional en la capacidad de agarre.

Abstract

Currently, additive manufacturing process is one of the methods used to make complex components in the shortest possible time. The main point of this degree work is the functional evaluation of the grip of an exoskeleton prototype built by additive manufacturing. Construction of the prototype is based on the plans made in the degree project of fellow Josué Ariel Garzón. The plans were redrawer to build a custom prototype, changing measurements and in other cases designing completely different new parts. The printing process of the object must go consecutively, starting with the design of the object in SolidWorks. Second, define the printing parameters in Cura Ultimaker where the thickness, filling, support, speed, type of adhesion, etc. are established. Third, the parameters are decoded, and we proceed to print. For the lifting of the protocol, mobility parameters are established, for this an investigation of the forearm muscles is carried out and the movement that must be carried out for these muscles to activate, this activation of the muscles can be registered by means of bio signals using sensors EMG. Test persons are subject to several data collection activities. These results are processed in MATLAB to have a better understanding and identify the functionality of the exoskeleton.
