How can robots contribute to quality control in manufacturing?

• A. Through precise measurements, consistent assembly, inspection with vision, real-time feedback, and data logging
• B. Only mass production
• C. Only manual inspection
• D. Replacing all inspection with tests

Answer: (D)

Robots strengthen quality control by integrating precise measurements, consistent assembly, vision-based inspection, real-time feedback, and data logging. Precise measurements reduce variation and catch dimensional errors early; consistent assembly ensures products meet the required dimensions and fittings; vision systems enable fast, objective inspection of features that are hard for humans to judge; real-time feedback allows immediate adjustments to processes to stay within tolerances; and data logging provides traceability for root-cause analysis and continuous improvement.

The other statements miss essential QC capabilities: robots do more than enable mass production, they can perform automated inspections (not just manual); and replacing all inspection with tests isn’t accurate, since inspection and testing serve complementary roles and automation can handle both tasks.
