The needle/sample transport is a multifunctional module capable of moving
the needle into various positions (such as different wells in two different
plates, different vials, needle wash position and the needle-seat position). The
active movable axes are the X-axis, the Z-axis and the theta-axis, the
vial-/plate pusher is an additional passive axis. All axes are stepper motor
driven and encoder controlled in order to have tight feedback for the axes
position. The theta and Z axes have spring loaded belt-tensioner.
