According to the development process of the robot, it is usually divided into three generations, respectively are: (Multiple Choice)

Question

Options

• ATeaching Reproduction Robot
• BRobot with sensation
• CRobots that will think
• DIntelligent robot

• A
  84% (43)
• C
  16% (8)

Explanation

Robotics history is standardly divided into three generations, each representing a leap in capability. First-generation robots (A) are Teaching Reproduction (playback) robots - they are manually guided through a task, record the movements, and repeat them exactly, with no environmental awareness. Second-generation robots (B) introduced sensors (vision, touch, force), allowing them to perceive and adapt to their surroundings. Third-generation robots (D) are Intelligent robots, capable of autonomous decision-making using AI, reasoning, and learning.

Option C ("Robots that will think") is incorrect because it is not a recognized generation in the standard classification - it conflates a vague futuristic concept with the established term "Intelligent robot" (D). Choosing both C and D would be redundant and C is simply not the accepted academic label.

Memory tip: Think of the three generations as Repeat → React → Reason - first they repeat programmed moves, then they react to sensors, then they reason intelligently. Match each verb to A, B, and D respectively.
