Question 1

What is the primary purpose of a safety light curtain in an automated manufacturing cell?

Accepted Answer

Creating an invisible detection barrier that stops machines when a person enters the hazard zone

Answer

Safety light curtains project a grid of infrared beams; interrupting any beam triggers an immediate machine stop, protecting workers from entering hazardous areas.

Question 2

Which motion profile minimizes mechanical vibration and jerk in high-speed automated machinery?

Accepted Answer

S-curve (sinusoidal) velocity profile

Answer

S-curve profiles gradually ramp acceleration and deceleration, reducing jerk and mechanical stress, which minimizes vibration in high-speed automated systems.

Question 3

In machine vision for quality control, what is the purpose of camera calibration?

Accepted Answer

Correcting lens distortion and establishing real-world coordinate mapping

Answer

Camera calibration corrects geometric lens distortion and establishes the relationship between image pixels and actual physical dimensions for accurate measurement.

Question 4

What distinguishes a collaborative robot (cobot) from a traditional industrial robot in terms of safety design?

Accepted Answer

Cobots are designed with force/torque sensing and speed limits to operate safely near humans without physical guarding

Answer

Cobots incorporate force-torque sensing, power-and-force limiting, and reduced speeds per ISO/TS 15066 to enable safe human-robot collaboration without traditional safety cages.

Question 5

In automated welding processes, what is the role of seam tracking?

Accepted Answer

Adjusting the welding torch position dynamically to follow the actual joint path

Answer

Seam tracking uses sensors (laser, vision, or arc-based) to detect the actual weld joint position and dynamically correct torch path deviations caused by fixture tolerances or thermal distortion.
