(d) Statement 1: "The use of multiple extra actuators requires the development of new control strategies to cope with the diverse interactions that may arise compared with standard systems with a single actuator." Statement-I is Correct. Using multiple actuators introduces complex dynamics and coupling effects between them. This necessitates advanced control strategies (like coordinated or decentralized control) to ensure proper functioning, stability, and performance. Statement 2: "Two-degree-of-freedom actuators can also be designed to combine two motions, like the roto-translational direct drive motor." Statement-II is Correct. Two-DOF actuators combine motions (e.g., rotational + translational), and roto-translational direct drive motors are a classic example. Such actuators are used in precision applications where coordinated motion is necessary. Statement 3: "Their response time is tens to hundreds of milliseconds, but they can be profitably used in many mechatronic applications." Statement-III is Correct. While some actuators may have response times in this range, many mechatronic applications (e.g., manufacturing, medical robotics) can tolerate such delays, making these actuators useful despite their response characteristics.
