Q76. During a design review, an engineer must reason about open-loop control rather than rely on a memorized label. Which statement is defensible?

A. control that continuously corrects from feedback B. control that always requires a camera C. control that eliminates all disturbances D. Control in which the command is applied without using measured output to correct it

Check Answer

Correct Answer: D   |   Marks: 1

Explanation: Open-loop systems do not use output feedback, so disturbances and model errors are not automatically corrected. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.

Q77. Which option correctly identifies the function or significance of steady-state error in robotics? (select the best answer)

A. The remaining difference between reference and output after transient behaviour settles B. the maximum robot reach C. the total number of links D. the time required to load a program

Check Answer

Correct Answer: A   |   Marks: 1

Explanation: Steady-state error measures final tracking offset; controller type and plant characteristics determine whether it can be eliminated. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.

Q78. A robotics student is asked to distinguish integral action from unrelated system features. Which answer is correct? (select the best answer)

Check Answer

Correct Answer: B   |   Marks: 1

Explanation: Integral action can remove steady-state error but may contribute to overshoot and integral windup if not managed.

Check Answer

Correct Answer: C   |   Marks: 1

Explanation: P responds to present error, I accumulates error over time, and D responds to error rate; tuning balances speed, stability and noise sensitivity. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.

Q80. In a technical review of a robot, which statement about trajectory tracking should be accepted? (select the best answer)

A. holding a single fixed pose forever B. measuring payload without motion C. defining only the base frame D. Controlling a robot to follow a time-parameterized desired path or motion

Check Answer

Correct Answer: D   |   Marks: 1

Explanation: Trajectory tracking requires the robot to follow desired position/velocity profiles over time, often using feedback and feedforward. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.

Check Answer

Correct Answer: A   |   Marks: 1

Explanation: Servo loops use feedback and drives to make motion follow reference commands with suitable dynamic performance.

Q83. A robotics student is asked to distinguish closed-loop control from unrelated system features. Which answer is correct? (select the best answer)

A. control with no measurement of output B. a mechanical gripper type C. Control that uses feedback to compare actual output with a reference D. a coordinate transformation

Check Answer

Correct Answer: C   |   Marks: 1

Explanation: Closed-loop control calculates error and adjusts the command, helping compensate for disturbances and uncertainty. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.

Q84. Which statement would be the soundest basis for explaining overshoot to a new robotics engineer? (select the best answer)

A. the number of robot axes B. the minimum sensor range C. the controller's memory usage D. The amount by which a response exceeds its target during a transient

Check Answer

Correct Answer: D   |   Marks: 1

Explanation: Overshoot is a transient-response characteristic; excessive overshoot can cause vibration, collision risk or poor process quality. A rigorous engineering decision also considers modelling assumptions, coordinate conventions, uncertainty and safety constraints; a definition alone is not sufficient to validate an implementation.
