This thesis focuses on the field of prosthetics, especially the issue of active prosthesis control. The goal is to perform a comprehensive analysis, design and construction of a prosthetic system that, based on the analysis of sensory data (such as an EMG signal from multiple channels), can correctly classify a gesture and a subsequent moving of the limb model. The first parts of the thesis are an important description of the critical components and important parameters of the active prosthesis system, including comparison and selection of available open source solutions. Next is a proposal of interconnection and description of individual hardware and software components. It also includes documentation of the real constructed system, which consists of the InMoov robotic hand, the Raspberry Pi controller and accessories. The results are critically evaluated in the last part of this work.

Sua estrutura foi fabricada em impressora 3D. Para o interfaceamento homem-máquina foi desenvolvido um shield, que realiza a aquisição de sinais eletromiográficos, com dois canais, armazenamento em cartão SD e um sistema eletrônico capaz de gerar um banco de dados com movimentos realizados pela mão humana. Foi utilizada a plataforma Arduino para processamento e programação. O sistema contém um aplicativo com protocolo de acionamento programável e inserção de movimentos, proporcionando independência ao usuário. Foram realizados testes nos quais o sistema implementado executou movimentos, após armazenar vários movimentos funcionais da mão. Isso foi possível devido ao desenvolvimento de um algoritmo capaz de reconhecer, quantificar e armazenar os sinais produzidos pelas contrações dos músculos. A prótese ativa implementada funcionou adequadamente para paciente com deformidade congênita e para paciente amputado. O valor total dos componentes mecânicos e eletrônicos necessários para implementar a prótese ativa e a utilização de hardwares e softwares livres contribuem para que o custo do dispositivo seja reduzido. / This paper describes the implementation a low cost hand prosthesis, a mechanism constituted by sixteen degrees of freedom, five articulated fingers individually, driven by mechanical tendons. Its structure was made in a 3D printer. For the man-machine interfacing, a shield was developed which performs the acquisition of electromyographic signals, with two channels, SD card storage and an electronic system able to generate a database of movements made by the human hand. The Arduino platform was used for processing and programming. The system contains an app with a programmable drive and insertion movements protocol, providing independence to the user. Tests were conducted in which the implemented system performed movements, after storing various functional hand movements. This was possible due to the development of an algorithm capable of recognizing, quantifying and storing the signals produced by muscle contractions. The implemented active prosthesis worked well for patients with congenital deformity and amputee. The total value of the mechanical and electronic components required to implement the active prosthesis and the use of free hardware and software contribute to the low cost of the device.

This thesis deals with the current state of development of active lower limb prostheses and focuses mainly on own design of active prostheses. The introduction deals with the anatomy of lower limb and briefly describes the walk cycle. In other chapters are summarized amputation techniques in the lower limb, followed by a description of the allocation of prostheses according to the level of amputation, which were described in earlier chapters. The thesis also deals with the division of prostheses according to the patient's activity level and briefly describes the structural differences in these individual cases. Chapter describing the actual development in the field of active prostheses initiates part dealing with the detailed description of the part of the prosthesis. The following chapters deal with the design and implementation of a prototype of active transfemoral prosthesis. The penultimate chapter deals with the software description of all parts of the prosthesis. This chapter is followed by an evaluation of the achieved results.
