| Research Abstract |
Human posture control mechanism for adapting to unstable environment is investigated through walking and running experiment under unstable environment. By statistical analysis of the measured motion, independent control of limb axis orientation contributing on the forward motion and that of limb axis length contributing on the body stiffness was found. Then, in order to consider the change in body motion under low stiffness (unstable) environment, we focused on the adaptive change of body stiffness (i.e. limb axis length). When the leg stiffness was decreased by spring shoes, human motion changed so that the whole body motion matched the stiffness of shoes. In the meanwhile, when the floor stiffness was decreased by spring floor, body stiffness did not change and duty ratio changed instead. By analyzing shared control low for realizing these motions under various unstable environment, the existence of control for maintaining the limb axis length was found.
