Real time iris controlled robot

Abstract

Disability of movement has huge impact on the life of physically disable people. Therefore there is need to develop a robot which can be controlled using iris movement. Presently iris controlled robotic systems exist in which iris movement detection is done using MATLAB. This paper proposes a system which aims to design a robot which is controlled by iris movement. The system is designed using Raspberry Pi and Pi Camera Module which make the system cost effective and stand alone. An Open Source Computer Vision is integrated on Raspberry Pi for real time image processing. A general purpose higher-level language, Python is used for programming the Raspberry Pi. The main idea of the system is recognizing iris from an image of eye and finding out centroid of an iris. In the proposed system command is given to robot depending on centroid position. The command can be FORWARD, LEFT or RIGHT when the iris is at the center, left and right respectively. Command STOP is generated when there is failure of iris detection.
