What are some characteristics that promote the use of industrial robots?

• A. Hazardous work environments, repetitive work cycles, and multishift operations.
• B. High energy efficiency and low maintenance costs.
• C. Hazardous work environments, repetitive work cycles, difficult handling tasks, multishift operations, infrequent changeovers, and established part position and orientation.
• D. Limited procedure changes and small batch production.

Answer: (C)

The main idea is that robots are most attractive when the task is dangerous or tedious, needs high precision, and runs for long periods with little change. In hazardous environments, robots can work safely where humans cannot. For repetitive work, they deliver consistent speed and accuracy over long production runs. When handling tasks are difficult—such as awkward grips, heavy objects, or delicate placement—robots can use specialized end-effectors and controlled motions to improve reliability. Multishift operations and infrequent changeovers fit automation well because the robot can keep running with minimal downtime for reprogramming or setup. Additionally, having a well-defined part position and orientation makes automation much easier and more dependable, since the robot’s motions can be tightly planned around fixed references.

So, this combination of hazardous environments, repetitive cycles, challenging handling, extended operating hours, and stable part positioning is what makes industrial robots particularly advantageous. The other options miss some of these key elements or describe situations where automation offers less clear benefits.
