    Abstract

    In our previous work, we developed a compact 6-DOF haptic interface. The haptic interface contains a modified DELTA parallel link positioning mechanism. A stiffness of the modified DELTA mechanism is affected by elastic deformations of both parts and bearings. Therefore, to design such a parallel mechanism, we should analyze structural stiffness of a parallel mechanism, including elastic deformation of both parts and bearings. Then, we have proposed an analysis method of structural stiffness for a parallel mechanism. In this paper, we design a modified DELTA mechanism with a suitable stiffness, using our stiffness analysis method.
