EOG Signals-Based a Robot Implementation

This paper presents a novel hands-free control system for a mobile robot as a ground vehicle, which is based on EOG (ElectroOculoGram) signals. Horizontal human eye movements result in electrical signals at ocular muscles, which are sensed and amplified to produce the EOG signal. This EOG signal is translated to produce the DC motor's control signal, which can drive a ground vehicle movement totally in the analogue domain. The results show that this EOG signal can possibly control the rotation direction of a DC motor and it is expected that this study pertaining to man-machine interaction will help to further develop control methodologies used in assistive devices for disabled people.
