Abstract
When the user operates various types of slave robots in master-slave system, the fact that the dimensions of user does not match the dimensions of slave robot influence on the task performance. In particular, it is important to define analytically the effect of disparity between user and robot upper/forearm dimensions. In this paper, we describe the methods of arm posture representation and present the effect of ratio of upper/forearm length on the task performance. From the evaluation results, we can conclude that the effect on working task performance is small in case of disagreement between user and robot upper/forearm dimensions is lower than 20 percent.
