碩士 / 中華科技大學 / 電子工程研究所碩士班 / 99 / Visually impaired people have long been facing the dark space. They can’t realize the colorful world with the vision, hence they have to rely on the tactile, the smelling and hearing to feel and experience the environment. Lack of the video information, the blind may take action according to wrong decision-making and get in trouble when facing the challenge of outer circumstances and obstacles. It is very difficult for a blind pedestrian to accurately estimate the position and orientation by a walking stick or a guide dog. For this purpose, an intelligent wheeled mobile robot with guidance is designed to help blind pedestrians to move safely in this paper. The blind guiding systems, which integrate CMOS image sensor, radio frequency identification system (RFID), voice system, battery charger system and crash avoidance techniques, serve those outdoor blind pedestrians among obstacles and other hazards. The RF reader will be installed at the mobile robot. The RF tags will be fixed at the guide tile. Once the mobile robot come near the specificed guide tile, the voice system will be actuated to information included in guide tile or the braille system of facilities. In addition, the CMOS image sensor mounted on the mobile robot to detect the black markings on lead tiles, guide the blide to forward or turn around between two standard lines. Finally, the lithium battery charger system is designed for the guidance mobile robot, a microcontroller ATting25 is applied to supervise the capacity of battery during charging.
