4.2 Functional principle
Two fixed servo motors drive a toothed belt arranged in an H-layout.
The toothed belt moves the slide of the Y-axis and the interface located on the Z-axis in a 2-dimen-
sional space.
A controller calculates the position of the interface.
The interface is moved by the controlled interaction of the motors.
