Industrial robots must move heavy loads over long distances to be useful.

• A. True
• B. Not determinable
• C. Sometimes
• D. False

Answer: (D)

Moving heavy loads over long distances is not a requirement for usefulness. Industrial robots are valuable because they can perform repetitive, precise, and fast manipulations within a defined workspace—picking and placing parts, welding, painting, assembling, or inspecting with high consistency. They come in many forms with different payloads and reach, and many tasks involve small to moderate payloads moved over short distances inside a cell. For transporting heavy items across long distances, other systems like conveyors, gantries, or autonomous mobile robots are typically used, or the movement is handled by specialized equipment rather than the robot arm alone. So the statement overstates a single scenario and overlooks the broad range of tasks robots can perform, making it false.
