We have been conducting research on ways to contribute to reducing the workload of caregivers. We developed a wheelchair capable of following a single accompanying caregiver in a parallel position. However, observations in actual care facilities revealed that people often move as a group: for instance, two caregivers each pushed a wheelchair together. Therefore, we now aim to develop a robotic wheelchair...
There is a saying that 95% of communication is body language, but few robot systems today make effective use of that ubiquitous channel. Motion is an essential area of social communication that will enable robots and people to collaborate naturally, develop rapport, and seamlessly share environments. The proposed work presents a principled set of motion features based on the Laban Effort system, a...
In real life applications, two-wheeled robots are considered to carry payloads of different sizes and at different positions or motion speeds the vertical axis. Studying the impact of those parameters should be considered in detail in order to account for their impact on the robot stability and the control mechanism. This paper investigates the impact of changing the payload position dynamically;...
Mobile robot companions are service robots that are mobile and designed to share our living space. For such robots, mobility is essential and their coexistence with humans adds new aspects to the mobility issue: the first one is to obtain appropriate motion and the second one is interaction through motion. We encapsulate these two aspects in the term Human-Robot Motion (HRM) with reference to Human-Robot...
This paper deals with design and control of a standing-operator mobile robot. Because the human operator stands on the robot, the required area for the operator is relatively smaller than that for the wheel chair (seated-operator) robot, and freed-up area can be used for passengers and/or transporting objects. In addition, the position sensor used for monitoring the center of gravity of the operator...
In recent years, much effort has been made to provide services to an elderly person living alone at home. An essential component of facilitating the person is to identify his location in the home environment. Fundamentally, three different methods are being focused by the research community to address the issue of localizing the person. Most common approach is to install a variety of sensor systems...
