Question

Assertion (A): The servo robot is a closed loop system

Reason (R): It allows for a feedback

(a) Both A and R are true and R is not correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A is false but R is true

This question was addressed to me in class test.

My question is taken from Robotic Control System topic in division Time Response Analysis, Design Specifications and Performance Indices of Control Systems

Answer 1

Correct option is (a) Both A and R are true and R is not correct explanation of A

The explanation is: A servomechanism, sometimes shortened to servo, is an automatic device that uses error-sensing negative feedback to correct the performance of a mechanism and is defined by its function and the servo robot is a closed loop system as it allows for a feedback.
