Which term refers to a simple mechanical arm with precise, high-speed motions that requires constant supervision by a human operator?

• A. Second generation robots
• B. Autonomous robots
• C. Collaborative robots
• D. First generation robots

Answer: (D)

Early industrial robots were simple mechanical arms designed for fast, precise repetitive motions, but they needed constant human supervision to guide, monitor, and control them. This combination—reliable high-speed accuracy paired with ongoing human oversight—fits first generation robots. They were not autonomous, and they weren’t designed to work safely alongside humans or with advanced teaching modes. Autonomous robots operate without continuous supervision, handling tasks independently, while collaborative robots are built to work with humans safely and typically include safety features. Second generation robots improve control and programming, reducing the need for hands-on supervision but still aren’t purely autonomous.
