Question

If a robot can alter its own trajectory in response to external conditions, then it is considered as

• A. Mobile robot
• B. Intelligent robot
• C. Expert robot
• D. Fifth gen robot

Hint:

Intelligent robots are distinguished by their ability to perceive their environment, process information, and adapt their actions (like trajectory) autonomously, without continuous human intervention, based on changing conditions.

Answer 1

The Correct Option is B

Step 1: Define the characteristics of different robot classifications.
Mobile robot: A robot that can move from one location to another (e.g., wheeled, legged, aerial). While mobility might be a prerequisite for altering trajectory, simply being mobile doesn't imply the ability to alter its own trajectory in response to external conditions.
Intelligent robot: A robot that possesses abilities such as sensing its environment, making decisions, learning from experience, and adapting its behavior or trajectory based on external conditions or internal goals. The ability to alter its own trajectory in response to external conditions (like avoiding obstacles, navigating complex environments, or adjusting to changing task requirements) is a key characteristic of an intelligent robot.
Expert robot: This term is not a standard classification of robot intelligence or capability. An "expert system" is a computer program that emulates the decision-making ability of a human expert. While an intelligent robot might incorporate expert system principles, "expert robot" is not a defined category.
Fifth generation robot (Fifth Gen Robot): This term is more associated with advanced robotics research and development goals, often including highly autonomous systems with advanced AI, learning, and human-robot interaction capabilities. While such robots would certainly be intelligent, "Intelligent robot" is a more direct and fundamental classification for the described capability. The concept of "generations" of robots is a broader, sometimes dated, classification.
Step 2: Identify the classification that matches the described capability.
The ability of a robot to "alter its own trajectory in response to external conditions" implies sensing, processing information, making decisions, and adapting its actions. These are core attributes of intelligent behavior in robotics. Therefore, such a robot is considered an intelligent robot. The final answer is \( \boxed{\text{2}} \).
