In this research, we focus on the impedance adjustment function of human to evaluate his/her mobility function in a quantitative way. We consider that pedaling exercise is suitable for measuring lower limb kinematic impedance parameters, and aim at the establishment of the method which measure lower limb kinematic impedance parameters during pedaling exercise. In this paper, we propose the method of estimating lower limb kinematic impedance parameters during pedaling exercise using a multiple joint link model to take into consideration movement of each body segment which was not taken into consideration in a previous study. As a result, it becomes possible to take into consideration the inuence of the gravity of each body segment, and it is thought that estimated accuracy improved.

In this article, we propose a cycling wheelchair controlled by the servo brake. The cycling wheelchair is a pedal-driven system and support the moving of many patients with impairment of their lower extremities. This wheelchair has a potential as a mobility assistive device to improve the daily activities. However, there are several barriers to use the cycling wheelchair in an outdoor environment. Especially, on downward slopes, patients cannot properly apply the braking torque to the pedal. This inability to slow the wheelchair presents a dangerous situation. On the other hand, the cycling wheelchair is an effective rehabilitation device, so that many patients to use it as an indoor training device. For rehabilitation, the device should have functions to not only apply the load to the patients but also encourage the patients to train. In this study, we propose a new cycling wheelchair for supporting both outdoor moving and indoor training. The cycling wheelchair has servo brake system and interface to connect the personal computer. By controlling the brake system, the velocity control in the outdoor environment is realized. In addition, the braking force can apply the load to the patients for their rehabilitation in the indoor environment, and they can also enjoy the computer game and virtual environment by using the cycling wheelchair as an interface such as key bode and joystick.

本研究は生活空間内において人間を支援するロボットの実用化に向けたより効果的な人間とロボットとの協調作業系の実現を目的として,ロボット自身,環境に存在する物体,協調作業の相手である人間の構造・運動の情報からそれぞれSelf-model,Object-model及びPartner-modelという構造・運動モデルを構築し,それらのモデルに基づく人間協調型ロボットの制御システムを提案することを目的にしている.本年度は,協調作業中においてロボットがSelf-Modelに基づいて自己衝突を回避するだけではなく,ロボットの周囲の物体の構造・運動情報から構築されるObject-modelに基づき,協調作業中における障害物回避,及び障害物回避と自己衝突回避を同時に実現する手法を提案し,実機を用いた実験を行うことによってその有効性を確認した.また,ロボットの関節可動範囲から構築したSelf-Modelに基づいて,ロボットが人間との協調作業中において関節の可動範囲限界等の問題を回避可能とする手法を提案し,実機を用いた実験を行うことによってその有効性を確認した.

Nowadays, with a recent interest in robots, a lot of portal/news sites about the robots appeared on the Internet, and some robot magazines are first published. Furthermore, the activities of science communication and outreach has intensified. Therefore, researchers of robotics should consider how to be involved in these media/activities and how to cooperate with it for the promotion of robotics. To solve these problems, both the researchers and the media/activities have to enhance mutual understanding and exchange with each other. In this paper, we get an overview of the current state of these media/activities and express our point of view how researchers to be involved in it.

"Women in Robotics" is the international community whose scope includes but not be limited to: students, engineers and researchers in robotics, human science and technology; who are interested in research and development activities conducted by women in these fields; who would like to explore technical and social needs of women for marketing; and who have interests in our activities. Our mission is to provide a venue for discussion and collaboration for technical development that creates enjoyable and efficient style of work and life. In this paper, we introduce our activities, and discuss aims and scope of the technical session at Robotics and Mechatronics Conference in 2007.
