| Research Abstract |
In the first year of the project, 2003, we combined the 3-Dimensional motion analysis system and the mechanical analysis system. It resulted that a new methodology to measure the axial rotation of the finger motion was developed and data base of hand motion was established with measuring the various hand movement in active daily living. On the other hand, we developed the finger force plate and measured the force vector in the fingertip at finger compression. In the second year, 2004, we developed the humanoid electric prosthetic hand which has a hand movement just as alive human hand, using the 3-dimensional data base of the hand motion. After all, there is a co-operative rhythm among the flexion angle of finger joints, and with this rhythm, it is possible to produce the human-like hand motion in the robotic prosthetic hand. In 2005, we investigated the perception of the digital cyber hand from 3-dimensional motion analysis data, in the virtual reality space. In this space, a disabled person with amputated arm could perceive as if his lost arm regenerated and the control of cyber arm was thought to be available for using the electric prosthetic hand. In order to develop this control system, we compared the real space and the cyber space and combined these two spaces. It resulted that the flexion angle of each finger joint of,the digital cyber hand should be transmitted to the control system of the electric prosthetic hand, and that this transmission would produce the humanoid artificial hand which has a human-like hand movement.
