The model is decomposed of multiple subsystems.
Subsystems can represent physical elements such as complete stages or basic simulink blocs.
These subsystems are shared among multiple files.

First, we consider perfectly rigid elements and joints and we just study the kinematic of the station.

This permits to test if each stage is moving correctly.

From the measurement of the position of the sample with respect to the granite and from the wanted position of each stage, we can compute the positioning error of the sample with respect to the nano-hexapod.
