Abstract

In this paper, we implemented system to detect obstacle in that develop a guidance robot for the visually impaired through sound. We used ultra sonic sensor to detect obstacle. We supposed the algorithm that classifies distance and direction of obstacle using information that produce correct warning negative sign according to direction and distance of obstacle. According to the experiment, a reagent could detect obstacle without sight information.
