一个盲人旅行者在不熟悉的环境中行走，一个移动的机器人在杂乱的环境中导航，这两个机器人都有一个重要的共同点：它们都有运动能力来执行运动，但它们都依赖于感觉系统来检测和避开障碍物。本文介绍了使用移动的机器人避障系统作为盲人和视障人士的引导装置。就像电子信号被发送到移动的机器人的运动控制器一样，听觉信号可以引导盲人旅行者绕过障碍物，或者，它们可以提供周围环境的“声像”。这一概念已经在一种名为Navbelt的新型盲人旅行辅助设备中得到了实施和测试。Navbelt为盲人电子旅行辅助设备（ETA）引入了两个新概念：它不仅提供关于沿行进路径沿着的障碍物的信息，而且还帮助用户选择优选的行进路径。另外，辅助水平可以根据环境的变化以及用户的需求和能力自动调整。实验样机。
A blind traveler walking through an unfamiliar environment and a mobile robot navigating through a cluttered environment have an important feature in common: both have the kinematic ability to perform the motion, but they are dependent on a sensory system to detect and avoid obstacles. This paper describes the use of a mobile robot obstacle avoidance system as a guidance device for blind and visually impaired people. Just as electronic signals are sent to a mobile robot's motion controllers, auditory signals can guide the blind traveler around obstacles, or alternatively, they can pro,ide an "acoustic image" of the surroundings. The concept has been implemented and tested in a new travel aid for the blind, called the Navbelt. The Navbelt introduces two new concepts to electronic travel aids (ETA's) for the blind: it provides information not only about obstacles along the traveled path, but also assists the user in selecting the preferred travel path. In addition, the level of assistance can be automatically adjusted according to changes in the environment and the user's needs and capabilities Experimental results conducted with the Navbelt simulator and a portable experimental prototype are presented.
