Msp430F149单片机语音导盲机器人硬件系统设计

摘要设计导盲机器人目的在于辅助视力障碍者在室内行走、寻物，增强视力障碍者适应环境的能力，保持人-机-室内环境之间更加良好的交互性。导盲机器人是为视觉障碍者提供辅助行动的工具，它利用传感器对周围环境进行识别探测，将获得的信息进行处理并做出相应的反馈，以帮助使用者有效地避开障碍。我国在智能移动机器人研究方面虽然已经取得了一定的成果，如地面自主导航车、水下自主机器人和飞行机器人等。但由于起步较晚，在研究和应用方面都落后于一些西方国家，而且还没有达到完全实用。而导盲机器人作为移动机器人的一种，研究其避障和路径规划，具有一定的理论和工程应用意义。51270

Abstract

The seeing eyes robot is designed to assist visually impaired people to walk in the room and look for things , to enhance the environmental adaptability ,and to maintain a more favorable interaction with the machine and the indoor environment. The seeing eyes robot is a tool , which provide guiding auxiliary for the visual disabilities. It use a variety of sensors to detect the surrounding environment, processed the detecting information and then provided the corresponding feedback to the driving device and the visually impaired, to help users efficiently avoid the obstacles . Although our country had already made certain progress in intelligent migration robot researching , such as ground autonomous navigation vehicle, submarine independent robot and flight robot and so on .But ,the robot researcing is starting very late, so we falls behind some Western countrys in the application aspect, and the robot has also not completely achieved usability in our country. The seeing-eye robot as a kind of mobile robot is researched in obstacle avoidance and path planning , which has certain theory and project application significance.

The paper focus on the design of the seeing eyes robot’s structure. It also describes the model and the application of RFID, ultrasound, voice and MSP430. The robot adopts MSP430F149 as the heart of control, through ultrasound, infrared, RFID and speech recognition modules achieves information integration and easily realizes the indoor obstacle avoidance ,voice search and other functions.

Keywords: MSP430F149；ultrasonic ranging module；Infrared sensing module； RFID module ；voice module
