In nature world, there are several plants that have particular structure. Drakaea, one of the kinds of Orchidaceae, is well known that its flexible structure allows the stem to move forward and backward to the stamen with an insect for pollination. In this study, we developed a circular shape spring structure inspired by Drakaea. The spring is introduced on a parallel structure to realize a precise and wide range of motion. The prototype has 2 DOF of rotations and 1 DOF of translation. The preliminary experimental result revealed its wide range of working area and highly accurate repeatability. The prototype in the video was developed for testing the feasiblity of the mechanism, and to be used for an industrial assembling machine for optical parts. This study was collaborated with an industrial company, and funded by JST.
