Robots of the future should communicate with humans in a natural way. Hence, we are especially interested in hand motion based gesture interfaces. The purpose of this study was to present a reliable means for human-computer interfacing based on hand gestures made in three dimensions, which could be interpreted and adequately used in controlling a remote robot's movement. In this paper we discus...

This paper proposes a mobile robot navigation method based on augmented reality technique using not only AR markers’ patterns but their configurations. Mobile requires self-location to navigate toward destination. The authors propose system for wheelchairs that uses position and orientation of markers as well information connoted in the marker patterns. technology is applied estimate relative l...

Methods Three cases of study and application of biomedical signals are analyzed: a) Development of a multisensorial prosthesis of upper limb commanded by myoelectric signals (sEMG) b) Development of a robotic wheelchair commanded by eye blinks (myoelectric signals sEMG) and by brain signals (EEG) c) Use of myoelectric signals (sEMG) from disabled children to interact with mobile robots in order...

Objectives: Wheelchairs are the prime mobility aid of persons with spinal cord injuries. Manual wheelchair propulsion puts a lot of demand on the cardiopulmonary as well as the skeletal system. The main purpose of the study was to compare the effects of both arm ergometry training and progressive resistance exercise training of upper limbs on resting heart rate and distance covered during wheel...

This paper presents the indoor mobile robot that moves automatically without needing environment information beforehand while recognizing the frontal surrounding environment with only one general camera. Based on the frontal image, the robot detects two boundary lines, some obstacle regions, and a moving direction. When the obstacle is detected, the avoidance or stop movement is worked accordin...

This talk focuses on the ambient intelligence for network robot systems including robots and/or sensor networks, smartphones, etc. It is one of the significant functions allowing robot services over multiple sites. As examples of ambient intelligence on the human trajectory and behaviors, the "ambient intelligence map" is introduced. Next, the robotic services of shopping support for elderly, t...

Many service robotic systems have been developed in order to improve care cost and the QoL (Quality of Life) of the elderly people in the population-aging society (Nagi, N. Newman et al., 2002; Schulz, D. et al., 2002; Stein, M. R. Stein et al. 2000). Our HARSP (Human-Assistance Robotic System Project) project has been developing a network distributed Human-Assistance Robotic System since 2000 ...

The ideas shown in this paper have been developed having in mind the main goal of designing a completely autonomous wheelchair prototype. The state of the art of mobile robotics is compared with the new trends in the field. The idea of autonomy made us focus our research in extracting the best from conventional Intelligent Mobile Robots techniques, looking towards the concept of Autonomous Mobi...

Abstract Assistive robots operate in complex environments and presence of human beings, but the interaction between them can be affected by several factors, which may lead to undesired outcomes: wrong sensor readings, unexpected environmental conditions, or algorithmic errors represent just a few examples possible scenarios. When safety user is not only an option must guaranteed, feasible solut...
