This paper presents the architecture as well as the implementation of a system that helps blind person navigate independently within an enclosed environment such as the home. The system uses a wireless mesh network to provide the first level localization. It also incorporates additional components to provide more refined location and orientation information. Optimal path planning is done by a server...
An indoor navigation system based on passive RFID is described. It allows the user to move autonomously resorting to a grid of RFID tags for localization and simple procedures to determine the position and to plan the route. Ad-hoc designed RFID tags permit to achieve reliable and accurate position estimation while a proximity algorithm allows real-time localization. Many details of the localization...
This paper presents methodologies and techniques for multi-sensory fuzzy hybrid navigation of an active mobile robot assistant for the elderly people in known, cluttered and dynamic indoor environments. For self-localization, the geometric and topological representations are combined together to maintain the advantages of them and counteract their disadvantages. By using RFID system, the estimation...
In practice, the environments in which mobile robots operate are usually modeled in highly complex forms and, as a result, autonomous navigation and localization can be difficult. The difficulties are exacerbated for practical robots with limited on-board computational resources and complex planning algorithms, since this paradigm of environmental modeling requires enormous computational power. A...
