Conference Proceeding: iWalker: Toward a Rollator-Mounted Wayfinding System for the Elderly
[show abstract] [hide abstract]
ABSTRACT: Research on intelligent walkers aims at helping elderly individuals to maintain their independence in familiar and unfamiliar environments. Several walkers have been developed by researchers at Carnegie Mellon University and the University of Pittsburgh. This article contributes to this research venue by describing the design and initial evaluations of iWalker, a multi-sensor rollator-mounted wayfinding system for the elderly. The primary difference of the proposed navigation aid from other intelligent walkers is that iWalker is assumed to operate in a smart world (SW), a physical space equipped with embedded sensors. By integrating inexpensive sensors into the environment, the cost and complexity of the walker can be reduced.RFID, 2008 IEEE International Conference on; 05/2008 -
Conference Proceeding: Path following for indoor robots with RFID received signal strength
[show abstract] [hide abstract]
ABSTRACT: We propose a novel method for robot path following in an RFID-equipped corridor using received signal strength (RSS). RSS measurements are recorded as reference fingerprints during the exploration phase. Then, these data are used to guide the robot through the corridor in the navigation phase. Distance and orientation that the robot derivates from the expected path are approximated through the RSS differences and the index differences of two antennas. Finally, a P-controller is used for the navigation of the robot. This enables the robot to follow a certain path, which may be defined in the first phase of our method. The extensive experiments with a SCITOS G5 service robot confirm the validity and robustness of our approach.Software, Telecommunications and Computer Networks (SoftCOM), 2011 19th International Conference on; 10/2011 -
