Abstract

Most of positioning devices are calibrated by comparing with an artifact or other measuring machine. These methods need an artifact or a measuring machine.<BR />On the other hand a Self-calibration is the best method for small or big positioning devices which are hard to make artifacts, because the method does not need an artifact.<BR />In the purpose of this study is to apply the Self-calibration to a parallel mechanism. In this paper, we built a small 3DOF (x and y direction and rotational movement around stylus) parallel mechanism and studied its movement. It was proved the method had the benefit for the mechanism by previous study.
