Compliant Positioning System with 6 DOF for High Precision Medical Standing Applications

This paper wishes to present a compliant platform solution with multiple degrees of freedom, with the role of compensating vibrations and parasitic movements. In addition, there are key issues regarding the aspects of tremor, especially in the medical field. Of course, the emphasis is on the impact that tremor (vibrations) has in microsurgery, where very high positioning accuracies are required. Of interest, regarding the construction of the proposed platform, are the compliant elements that bring a series of advantages, starting from the simplification of the entire system and up to the manufacturing process of the platform, which is made monolithically by selective laser sintering (SLS) from PA2200 polyamide powder.
