Which statement best describes the role of a z-axis manipulator in a typical part pickup module?

• A. Provides vertical movement for the gripper
• B. Provides horizontal movement
• C. Provides rotation
• D. Provides cooling

Answer: (A)

Vertical motion is what the z-axis manipulator provides in a part pickup module. It moves the gripper up and down so it can approach a part from above, lower to grasp, and then lift the part away from the surface. This up-down control is essential for reliably picking parts from a surface and placing them elsewhere, without changing the gripper’s horizontal position. The other axes handle different tasks: horizontal movement is achieved by moving the gripper along the plane (left-right and forward-backward), orientation is managed by rotation at the wrist to align the gripper with the part, and cooling is not part of the actuator’s role in the pickup motion.
