Design, Development, And Testing of a Servo Mounted Obstacle Detection System for Visually Impaired Individuals

Abstract: This paper proposes a cost-effective obstacle detection system for visually challenged individuals, which reduces the number of sensors required to cover the same area in front of the user, by rotating the sensor module. The system consists of time-of-flight sensors that can move to sweep a greater area than the stationary ones. The system transmits the signal to the user via a grid of vibration motors, informing the user of the distance, height, and how far to the side the obstacle lies. The system is tested to check whether the proposed system is viable for the intended purpose.
