The present invention relates to a robotic assembly, including: a plate (1) provided with a means for securing an object to be positioned with an orientation and predetermined position XY, and with a spatial resolution and a repeatability with variations of less than 0.34 arcminutes in terms of orientation and less than 5 microns in terms of position; a translatably movable vertical shaft (10) making it possible to position a tool in order to perform operations on said object secured to the plate; four motor-driven rotational shafts (2 to 5) connected together, two-by-two, by means of three arms (6 to 8) in a serial kinematic chain, the plate (1) being supported by the endmost shaft (5); and a frame (9) secured to the first motor-driven rotational shaft (2), as well as to a vertically movable tool holder (10), the plate (1) being movable and rotatable relative to said tool holder (10). |
