Question 1

Which type of automated guided vehicle (AGV) navigation uses magnetic tape or wire embedded in the floor to follow a predetermined path?

Accepted Answer

Fixed-path guidance

Answer

Fixed-path guidance AGVs follow physical guides like magnetic tape, wires, or painted lines, making them reliable but inflexible to path changes.

Question 2

In machine vision systems used for quality inspection, what is the function of a backlighting setup?

Accepted Answer

Creates a high-contrast silhouette to measure part dimensions

Answer

Backlighting illuminates from behind the part, creating a dark silhouette against a bright background, ideal for dimensional measurement and profile inspection.

Question 3

A robot work cell is designed with a light curtain at its entry point. Under IEC 62061, what category of safety function does this typically represent?

Accepted Answer

A presence-sensing safeguarding device

Answer

Light curtains are classified as presence-sensing safeguarding devices that detect intrusion into a hazardous zone and trigger a safe stop.

Question 4

What does the term 'degrees of freedom' (DOF) refer to when describing an industrial robot?

Accepted Answer

The maximum number of axes or independent motions the robot can perform

Answer

Degrees of freedom refers to the number of independent axes of motion a robot possesses, with most industrial robots having 6 DOF for full spatial manipulation.

Question 5

In pneumatic automation systems, what is the primary function of a Festo-style 5/2 directional control valve?

Accepted Answer

Directs airflow to extend or retract a double-acting cylinder

Answer

A 5/2 valve has 5 ports and 2 positions, routing compressed air to either side of a double-acting cylinder while exhausting the other side.
