ABSTRACT

This research activity was carried out within the national research program PRIN 2009 Micro Manipulation and Assembly MM&A, in collaboration with University of Brescia, University of Bergamo and ITIA CNR Milan.

The Machine Mechanics group was responsible for the design and implementation of a miniaturized orientation platform with 2 degrees of freedom, to be used in cooperation with a mini-manipulator for assembly operations of micro-scale components. The mechanical design led to the identification of a parallel architecture optimized to meet the required work space. In addition to the prototyping of the device, the research activity concerned the development of the control software, the calibration through vision system and the study of mechanical errors due to deformation of members and joints of the platform itself.
