Abstract
For safe walking of the people who are blind, walking assistance robot which can detecting and avoiding the obstaclewas investigated. The implemented protype walking assistance robot consists of a obstacle detecting module, a userat the front part of the robot can perceive the obstacle which is in 3 meter distances and 180o degrees. It calculates thedistance and degree from the obstacle using TOF (time of flight) method and decides the 3-dimensional location of theobstacle. The obstacle information is delivered to the user using acoustic alarm and guide sound. The robot is designedto avoid by itself when the obstacle is detecting and the user only follows it to safe walking. After the designed robotwas implemented, driving and obstacle detecting experiments were carried out. The result showed that the designedwalking assistance robot wil help the people who are blind to walk around safe.
