Abstract
This article describes the reslts of experiment to investigate the characteristics of two-handed simltaneous motion time in working areas.It is found through a statistical analysis the terminal activities, i.e.positioning and grasp motion time are affected by the working areas movement activities, i.e.transport emply and transport loaded motion time are not.Varieties of time in terminal activities are shown to be quadratic in separated distances betwen both hands.On the other hand, one-handed motion time is not affected by the working areas.Therefore, experimental equations to estimate simultaneous motion time as base on the one-handed motion time are given.
