Abstract

Nowadays, many technologies were developed to make blind people or disabled people life easier. Before the advent of such technologies, blind people using traditional stick or guide dogs to move from one place to another but required extensive training period. Therefore, an assistive robot system using ultrasonic sensor for indoor navigation was proposed to help blind people who have difficulties in terms of mobility or navigation. Based on the problem arise, assistive robot that can operate using smart phone was developed for navigation in the house. Besides, it can replace the cane and guide dogs for disabled people who moving in new place. This robot was controlled wirelessly via Bluetooth module and voice commands. The main microcontroller of this robot is Arduino Uno R3. This Arduino was controlled and connected to the device such as motor shield, Bluetooth module and Ultrasonic sensor. The software implementation that used as interface with the hardware is Arduino IDE. This robot start functions when users say „Forward‟ through Arduino Bluetooth Control apps that have been installed in the smart phone. From the result, the sensor will detect an obstacle within 20 or 25 cm and the buzzer will active at the same time which can notify the user about the object in their path. The average time decision of this robot to move either right or left is 4.204 seconds followed by the sound of buzzer. Through this project, it can be concluded that Assistive Robot is suitable for blind people who are not familiar in the new environment and help them move safely.
