Diseño e implementación de exoesqueleto para simulación de prótesis mioelectrica de antebrazo transradial

Abstract

This project is an exoskeleton developed to simulate a forearm transradial myoelectric transradial The methodology employed in the development of this project will be as follows. You want to acquire the signal by means of electrodes, these capture myoelectric signals "small voltage produced by the muscles to be moved", which was leaked to leave a clean signal, and it is adjusted to the desired electrical levels. Subsequently seeking to enter this signal to an Arduino Nano that meets the control function of the whole system, this in turn manipulate a small actuators "servomotors" that will be supported by a power amplifier which is powered by a battery li-po, thus the prosthesis may have movement, which depends on tiny electrical signals captured by moving the muscles, for this project at first the weight of the exoskeleton is not taken into account because it is a pilot project, but if a brief investigation which would be the right material for a final prosthesis. In addition to this the exoskeleton has a structure that simulates the prosthesis, this has fingers which each have independent movement. The prototype is designed in Solidwork. The same is based on the INMOOV project which is open source. This was made minor modifications to implement this project, the entire structure was developed in ABS5 plastic with a 3D printer Solidoodle 2nd generation. This project was conducted at the University Francisco Jose De Caldas.
