• A. Pneumatic
• B. Electric servo motors
• C. Hydraulic
• D. Stepper

Answer: (A)

Non-servo pick-and-place devices rely on fast, simple actuation. Pneumatic cylinders fit this need because compressed air turns into rapid linear motion with minimal moving parts, making them cheap and robust for repetitive tasks. Control is typically just on/off through valves, with sequencing handled by simple sensors or limit switches rather than closed-loop feedback. This makes pneumatic actuation ideal for quick, short-stroke movements and straightforward grasping in a non-servo setup. Electric servo motors and steppers involve position feedback for precise control, which adds complexity and cost, while hydraulic actuation, though strong, is heavier and slower for the rapid motions these machines perform. Therefore, pneumatic actuation is the best match for non-servo pick-and-place devices.
