振動刺激を用いた荷重条件下における動作変更に関する研究

Abstract

To assist not only motor function but also perception ability of elderly persons and/or handicapped persons, the power-assist robots which has perception-assist function have been studied. These robots can automatically modify the user’s motion when the robot detects inappropriate user’s motion or a possibility of accident such as collision between the user and obstacles. For motion modification in perception-assist, some actuators of power-assist robot are used. On the other hand, since some elderly persons, handicapped persons or some workers need not use power-assist but only perception-assist, another simple perception-assist method was investigated in our previous study. In this perception-assist method, only vibrators are used for generating motion change with kinesthetic illusion to assist perception-ability only. In this study, since the perception-assist is often used during tasks under loaded condition, the features of motion change under loaded condition are investigated.
