Introduction
Operating Principle
Transport Assembly
The transport unit comprises an X-axis slide (left-right motion), a Z-axis arm
(up-down motion), and a gripper assembly (rotation and vial-gripping).

Transport Assembly
The transport assembly uses four stepper motors driven in closed-loop mode
for accurate positioning of the gripper assembly. The rotational movement of
the motors is converted to linear motion (X- and Z-axes) by toothed belts
connected to the drive spindles. The rotation (theta axes) of the gripper
assembly is transferred from the motor by a toothed belt and series of gears.
The opening and closing of the gripper fingers are driven by a stepper motor
linked by a toothed belt to the planetary gearing inside the gripper assembly.
