Abstract

The objective of brain computer interfaces (BCI) is to create a novel communication channel between the user and the outside world. Thus a person can interact with its surrounding using the electrical activity of the brain only. In this study, dual EEG activity is used successfully to control a 5 degree of freedom robotic arm. P300 event related potential (ERP) is used to select between 5 servo motors while Steady-State Visually Evoked Potentials (SSVEP) are used to move the chosen motor in opposite directions. Finally, a camera pointed at the robotic arm is used for providing visual feedback about the position of the robotic arm.
