Q76. During a design review, an engineer must reason about Cartesian robot rather than rely on a memorized label. Which statement is defensible?

A. a robot with only spherical joints B. a robot that must use legs C. a robot with no controlled axes D. A robot whose principal axes are three mutually perpendicular linear motions

Check Answer

Correct Answer: D   |   Marks: 1

Explanation: Cartesian robots use linear X, Y and Z axes, giving a typically rectangular-prismatic work envelope. 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 singularity in robotics? (select the best answer)

A. A configuration where the robot loses one or more instantaneous motion capabilities or the Jacobian becomes rank-deficient B. a routine maintenance interval C. the largest payload condition D. a gripper opening setting

Check Answer

Correct Answer: A   |   Marks: 1

Explanation: At a singularity, certain Cartesian motions may require very large joint rates or may be unattainable instantaneously. 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: Reach is a geometric capability, not payload or repeatability. 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: C   |   Marks: 1

Explanation: The combination of base rotation and linear extension produces a cylindrical-type workspace.
