For supporting daily activities of elderly and physically disabled people who have lost their body functioning of motions, we have developed a 7-DOF robotic exoskeleton system. It is intended to assist the motions of shoulder and elbow by mounting this on a wheel chair since human shoulder and elbow motions are involved in a lot of activities of everyday life. The proposed mechanism can maximize workspace...
This paper gives an advanced driving control system considering sway suppression of a passenger on an electrical wheelchair. The proposed driving control system is constructed on virtual experiment with motion analysis. To suppress the sway of a passenger's posture, the wheelchair driving pattern is optimized using the passenger's posture model. In order to verify the effectiveness of the proposed...
This paper describes a novel driving control scheme of electric power assisted wheelchairs based on human characteristics learning. ??Electric power assisted wheelchair?? which assists the driving force by electric motors is expected to be widely used as a mobility support system for elderly people and disabled people. However, some handicapped people such as paralysis of the muscles of one side of...
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...
Personal robots and robot technology (RT)-based assistive devices are expected to play a major role in our elderly-dominated society, with an active participation to joint works and community life with humans, as partner and as friends for us. In particular, these robots are expected to be fundamental for helping and assisting elderly and disabled people during their activities of daily living (ADLs)...
Today, the Internet is used to offer different services to users. Most of these services are designed for human users, but unfortunately some computer programs are designed which abuse these services. CAPTCHA (completely automated public Turing test to tell computers and human apart) systems are designed to automatically distinguish between human users and computer programs and block such computer...
This paper addresses a new collaborative control method for robotic wheelchairs. The original method was specifically designed for disabled people who are unable to drive a robotic wheelchair on their own. Its main novelty was that the wheelchair just provided the amount of help needed at each moment, to avoid loss of residual abilities. This wheelchair was tested by volunteering in-patients in Casa...
This paper presents the PAS-Arm (passive assist arm), a novel assist arm based on passive robotics. PAS-Arms are intended for direct physical interaction with a human operator. PAS-Arms are physically passive. Their purpose is not to enhance human strength but to produce specified but arbitrary two-dimensional guiding surfaces that constrain and guide the motion of the human operator. PAS-Arms have...
Summary form only given. In the coming advanced age society, an innovative technology to assist the activities of daily living of elderly and disabled people and the heavy work in nursing is desired. A wearable power assist robot is one of effective approaches as such technology, which is equipped to the human body to assist the muscular force. Since this kind of robot directly acts on the human body,...
In the coming advanced age society, an innovative technology to assist the activities of daily living of elderly and disabled people and the heavy work in nursing is desired. To develop such a technology, an actuator safe and friendly for human is required. It should be small, lightweight and has to provide a proper softness. A pneumatic rubber artificial muscle is available as such actuators. We...
The demand for rehabilitation robots is increasing for the upcoming aging society. Power-assisting devices are considered promising for enhancing the mobility of elderly and disabled people. Other potential applications are for muscle rehabilitation and sports training. The main focus of this paper is to control the load of selected muscles by using a power-assisting device, thus enabling ldquopinpointedrdquo...
Especially for severely disabled people, a powered wheelchair is an important means to participate in societal life. To optimally support people in need without putting an additional burden on them, methods have been developed to enable controlling an electrically powered wheelchair on the basis of the user's natural gaze behavior. While existing approaches consider psychological/physiological research...
As rehabilitation robots are increasingly serving to improve the quality of life for physically disabled people in clinical environments, the concept of emotional expressiveness in robots becomes increasingly important. The human perception of robot's emotional expressions plays a crucial role in human robot interaction. Virtual expression systems outperform hardware systems in realizing human like...
Nowadays the Internet users are from different ages and groups. The disabled people also use the Internet. Some Web sites are especially created for disabled people. Many Internet sites offers services for human users, but unfortunately some computer programs are designed to abuse these services. To solve this problem, some systems named CAPTCHA (completely automated public Turing test to tell computers...
In this paper we present a methodology to drive the end effector of a robotic manipulator, to which is attached a human hand, in order to follow the human's intention of movement. This set-up is inspired from a neuro-robotics scenario in order to develop systems for restoring motor functionalities in injured and disabled people. Three typical tasks are considered, namely the robot not to interfere...
