Guido是由Haptica（爱尔兰都柏林）开发的智能步行者，是一款机器人助行器，可以满足体弱视障者的需求，为他们提供独立锻炼的安全手段，以及在新环境中的导航辅助。它是基于1995年至2000年在都柏林的Trinity学院的一项研究计划。随后开发了许多类似的设备，例如来自Kosuge和Hirata实验室的RT-步行者、由医疗自动化研究中心开发的步行者、以及在马萨诸塞州理工学院（MIT）开发的用于移动性和监测的个人辅助（PAMM）设备。Guido具有重要的独特特征，例如其设计，商业化以及最近开发的基于地图的导航。在成功地将Guido的预生产单位出售给美国退伍军人事务部之后，它在2002年初因9/11和互联网崩溃的后果而退出市场。最近，我们启动了一项研究计划，以更新Guido，并在同步定位和地图绘制（SLAM）方面取得最新研究成果。在这篇文章中，我们回顾了Guido的设计和开发，并继续描述在办公室和养老院环境中进行经验评估的更新，然后与以前的控制策略进行比较。最后，讨论了其影响，并概述了未来的工作。
Guido, a smart walker developed by Haptica (Dublin, Ireland), is a robotic walking aid that addresses the needs of the frail visually impaired, providing them with a safe means of taking exercise independently as well as navigation assistance in new environments. It was based on a program of research in the Trinity College Dublin from 1995 to 2000. Many similar devices have subsequently been developed, such as the RT-Walker from Kosuge and Hirata Laboratory, the walker developed by Medical Automation Research Center, and the Personal Aid for Mobility and Monitoring (PAMM) devices developed at the Massachusetts Institute of Technology (MIT). Guido has important distinctive characteristics such as its design, its commercialization, and its recently developed map-based navigation. Following the success with the sales of preproduction units of Guido to the U.S. Department of Veterans Affairs, it was withdrawn from the market in early 2002 following the aftereffects of 9/11 and the dot-com crash. Recently, we have initiated a program of research to update Guido, with the latest research results in simultaneous localization and mapping (SLAM). In this article, we review the design and development of Guido and go on to describe the updates that have been empirically evaluated in office and nursing home environments and compare then with the previous control strategy. Finally, the implications are discussed and its future work outlined.
