We construct a prototype of a dual-axis positioning and pointing mechanism composed of multiple drive modules and conduct resolution tests using two control methods: synchronous control and independent control. When synchronous control is used, the output shaft achieves a resolution of 0.38µrad, while with independent control, the resolution of the output shaft reaches 0.0276µrad.The research results show that the positioning and pointing mechanism proposed in this study achieves high resolution through stick-slip driving principle, offering a novel approach for the advancement of such mechanisms.
