On which of the following approach A basic line following robot is based?2 pointsa) Applied approachb) Weak approachc) Strong approachd) Cognitive approach

A basic line-following robot is primarily based on the Weak approach.

Explanation:

1. Weak Approach: This methodology uses simple rules and sensors to respond to environmental stimuli. A line-following robot typically relies on infrared sensors to detect the contrast between the line (usually black) and the surface (usually white) and adjusts its movements accordingly. It operates without advanced reasoning or understanding, which characterizes weak AI.

2. Other Approaches:

   • Applied Approach: This might involve using the robot to perform specific tasks, but it's not a categorized theoretical framework like the others.
   • Strong Approach: This represents AI that can understand and reason about the world at a level comparable to human intelligence.
   • Cognitive Approach: This generally involves mimicking human thought processes and problem-solving strategies, which is beyond the capabilities of a basic line-following robot.

Thus, the answer is b) Weak approach.
