EEG Controlled Ni Lego Robot: Feasibility Study of Sensorimotor Alpha Rhythm Neurofeedback in Children

Abstract

We present a feasibility study of the novel system for EEG based neurofeedback. The proposed system can provide both continuous visual feedback on the computer screen and discrete reinforcement (movement of the NI LEGO Mindstorms robot) when the task is executed. We have tested the NF system on 31 children subjects (6-15 years). The subjects' task was to increase their alpha band power by using the continuous feedback. When the power level reached the predefined threshold, the command was sent to the robot to make a step which was considered a successful task execution. The preliminary results showed an overall increase of robot-activations during the course of the trials.
