Which generation of robots is characterized by simple mechanical arms with precise motions at high speed but requiring constant human supervision?

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

Answer: (D)

Early automation focuses on speed and precision, but without autonomy. First-generation robots use simple mechanical arms to perform fixed, repeatable motions at high speed. They excel at doing the same task quickly and with great accuracy, but they need a human to supervise, program, and intervene whenever something changes or a fault occurs. That constant human oversight is what defines this generation.

Second-generation robots introduce more flexible control and programming, allowing some tasks to be adjusted or reprogrammed without starting from scratch, which reduces the need for continuous supervision. Third-generation robots bring autonomous operation, sensing, and decision-making, enabling them to handle variations without constant human input.
