6自由度パラレルリンク機構を用いた指先装着型触覚ディスプレイの設計と試作

抄録

This paper presents a wearable fingertip tactile display for rendering of forces by skin deformation to index finger with six-Revolute-Spherical-Spherical(6-RSS) parallel link mechanism. It is composed of a static baseplate and a mobile endplate which are connected by six legs. The baseplate is located on the nail side of the finger and the mobile endplate can move in six-degree-of-freedom(6DoF), with contact-no contact capabilities, by the legs actuated by the motors. At first, we decided the operation range of the endplate on finger pad for rendering of orientation, stiffness, and weight. Secondly, we decided the parameters that include the length of arm and rod, the position where index finger are fixed. Finally, we designed a prototype using the parameters.
