Arduino based mobile robot controlled by voluntary eye-blinks using LabVIEW GUI & NeuroSky Mindwave Mobile Headset

Abstract

This paper proposes an experimental system of a brain-computer interface aimed to use the voluntary eye-blinks detected across the EEG signal acquired from a NeuroSky headset to control the movement directions of a mobile robot. Bluetooth protocol was used to achieve the communication between a LabVIEW application and a program uploaded in an Arduino Mega board which controls the movement direction of a mobile robot. Three parallel algorithms were implemented using LabVIEW, one for the voluntary eye-blinks counting, one for switching across buttons and one for selection of a certain command. Transition across commands (stop, go forward, go backward, turn left, turn right) is executed by one voluntary eye-blink, while two intentional eye-blinks determine the selection of a specific command.
