人の持ち上げ動作における違和感の発生メカニズムの解明及び予測質量の推定

When a human performs a lifting operation using a power assist device at a production site, if the operator's weight perception is different from his/her assumed, the operation may be different from the assumed one, which may cause discomfort. In this research, we analyze the lifting motion of a human when predicted mass by a human and perceived mass are different, and clarify mechanism of occurrence of discomfort. In addition, if it is possible to estimate the mass predicted by a human before perceiving the weight, and to apply it to the control of the assist device, discomfort during operation may be reduced. Therefore, we aim to estimate the predicted mass of a human.
