Desenvolvimento de protótipo de prótese controlada de mão por meio de manufatura aditiva

Abstract

This project aims to develop a prototype of a hand capable of reproducing the natural movements of a human hand, aiming at a low cost so that it is accessible to a greater number of people. Initially, there was a theoretical study on the main elements that make up the hand, as well as on the existing prostheses and their functionalities. Based on this context, the prosthesis prototype was conceived in order to consolidate itself as a viable alternative for a person who has suffered amputation or disability in one of the hands, or has an anomaly, in order to improve their quality of life. The prototype was manufactured using a 3D printing process from the open source prosthesis model, called HACKberry, making the necessary adaptations to improve the prototype. To transmit the instructions regarding the movements to the prototype, a remote control was used. In addition, the device has actuators, transducers and infrared receivers, which, together with a printed circuit board, carry out the control and movements of the fingers of the hand, which are programmed using the C language, performing the movement and activation tests.
