In order to maintain human health care, it is important to record daily activity. For recording daily human activity, monitoring system which consists of multiple micro electromechanical systems (MEMS) has been developed. Using the MEMS based monitoring system, numerical data of subject's activity can be stored into a database. For example, when subject's activity on a single day is recorded, a huge...
This paper describes a novel capacitor regenerative braking control scheme of electric powered wheelchairs for efficient driving on downward slopes. ??Electric powered wheelchair?? which generates the driving force by electric motors is expected to be widely used as a mobility support system for elderly people and disabled people, however, the energy efficiency has to be further improved because it...
A robot working with humans or other robots is supposed to be adaptive to changes in the environment. Reinforcement learning has been studied well for motor skill learning, robot behavior acquisition and adaptation of the behavior to the environmental changes. However, it is not practical that the robot learns and adapts its behavior only through trial and error by itself from scratch because huge...
We have been developing a Universal Mobile robot for Assistive tasks (UMA). The aim of UMA is to assist elderly and disabled person in an indoor location. UMA is able to transport daily use objects by following the user. This paper presents an early construction of UMA and experimental result of following a user using visual tracking as a first step.
This paper proposes a novel regenerative braking control system of electric wheelchairs for senior citizen. ldquoElectric powered wheelchairrdquo, which generates the driving force by electric motors according to the human operation, is expected to be widely used as a mobility support system for elderly people. This study focuses on the braking control to realize the safety and smooth stopping motion...
Both self-learning architecture (embedded structure) and explicit/implicit teaching from other agents (environmental design issue) are necessary not only for one behavior learning but more seriously for life-time behavior learning. This paper presents a method for a robot to understand unfamiliar behavior shown by others through the collaboration between behavior acquisition and recognition of observed...
Life-time development of behavior learning seems based on not only self-learning architecture but also explicit/implicit teaching from other agents that is expected to accelerates the learning. This paper presents a method for a robot to understand unfamiliar behaviors shown by others through the collaboration between behavior acquisition and recognition of observed behaviors, where the state value...
A simple self-transfer aid robotic system is proposed, and the evaluations on the human's physical burdens when using a transfer aid robotic system are presented in this paper. A person with weak leg muscles who uses a wheel chair is assumed to be the target user. By using the self-transfer aid robotic system, a user can transfer between a wheel chair and a toilet, for example. The proposed self-transfer...
