Abstract : This paper introduces a mobile application to guide visually impaired people in transportation using NXT robot to make their life easier in roads and sidewalks. Nowadays, there is a wide variety of applications on the mobiles GPS for guiding and tracking. We have used mobile GPS in our Android mobile application with the help of voice recognition feature to collect the needed coordinates to navigate the user by letting him to communicate with the mobile application and speaks his destination. NXT robot start moving after getting the needed coordinates from the mobile application without crashing because of the obstacle avoidance feature implemented in the robot program. The robot communicates with the mobile application using Bluetooth. Keywords: NXT; Robotics; Android; Mobile; GPS coordinates; Maps; Visually Impaired
