“…Research in AT and mobility aids has also focused in the last years on robotic walkers like VA-PAMAID (Rentscheler et al, 2003), Guido (Rodriguez-Losada et al, 2005), Care-o-bot (Graf et al, 2004), COOL aide (Wasson et al, 2007), ORTW-II (Nejatbakhsh and Kosuge, 2005) or iWalker (Kulyukin et al, 2008). All these systems share the same structure of the robotic wheelchairs (sensors, CPU, control software).…”

“…All these systems share the same structure of the robotic wheelchairs (sensors, CPU, control software). Some of these sensor sets usually include handlebar force sensors (Graf et al, 2004;Kulyukin et al, 2008;Wasson et al, 2007) that allow the control system to detect the users' intention in navigation terms. Other sensors included usually focus on obstacle detection.…”

“…They proposed intelligent robotics agents to support elders mobility but the main difference in our approach is the explicit use of intelligent software agents to support decision-making and to help in the interfacing with the user. More modern lines of research in the field of pedestrian mobility are represented by Cheng et al (2008) and Kulyukin et al (2008). The first is more oriented to avoid the fall risk and the second culminates a line of walkers developed at CMU.…”

Abstract:In this paper, we present the SHARE-it approach to the integration of agent technology with other existing technologies to build specific intelligent and semi-autonomous assistive devices for older persons and people with disabilities (both cognitive and/or motor). In particular, we explored the benefits of the concept of situated intelligence to build mobility platforms and other artefacts that enhance the autonomy of the target user group in their daily life so that they can be self-dependent enough to autonomously live in their preferred environment.

“…As a result, a very large number of tags can be needed for position tracking, which could not be economically profitable in large environments. Kulyoukin et al [18] propose to reduce the number of tags by using RFID mats. This solution is viable in corridors, but not in large rooms without obstacles or forced paths.…”

Abstract-This paper presents a position tracking technique based on multisensor data fusion for rollators helping elderly people to move safely in large indoor spaces such as public buildings, shopping malls or airports. The proposed technique has been developed within the FP7 project DALi, and relies on an extended Kalman filter processing data from dead-reckoning sensors (i.e. encoders and gyroscopes), a short-range radio frequency identification (RFID) system and a front Kinect camera. As known, position tracking based on dead-reckoning sensors only is intrinsically affected by growing uncertainty. In order to keep such uncertainty within wanted boundaries, the position values are occasionally updated using a coarse-grained grid of low-cost passive RFID tags with known coordinates in a given map-based reference frame. Unfortunately, RFID tag detection does not provide any information about the orientation of the rollator. Therefore, a front camera detecting some markers on the walls is used to adjust direction. Of course, the data rate from both the RFID reader and the camera is not constant, as it depends on the actual user's trajectory and on the distance between pairs of RFID tags and pairs of markers. Therefore, the average distance between tags and markers should be properly set to achieve a good trade-off between overall deployment costs and accuracy. In the paper, the results of a simulation-based performance analysis are reported in view of implementing the proposed localization and tracking technique in a real environment.

“…There are a few groups that are currently or have worked on intelligent walkers, namely groups at Virginia [30], CMU [8], Utah [12] and Japan [9]. However, we are unique in our work in that we do not limit the environment and that we rely heavily on low-cost and low-power visual sensors.…”
