Abstract |
ANIMA’s primary objective is to compare three non-conventional human-computer interfaces that comply with
the industrial robot ST Robotics R-17 instructions. The Motor Module presented in this work explains how brain
waves are obtained, processed, analyzed and identified according to facial movements produced by the subject.
The brain waves are obtained using an electrode cap which complains with the 10-20 international system for
electrode positioning. Together with the electrode cap a circuit for acquiring the EEG (Electroencephalographic)
signals was designed and constructed. A software tool was designed in order to process the EEG signals using the
Fast Fourier Transform technique; with this technique the software is able to identify specific facial movements,
and instructions are sent to the robotic arm, executing one of four predefined routines. The system was tested by 5
people, and all of them having successful results. Accuracy achieved by this module was of eighty nine point nine
percent.
