← TechnologyWhich control issue emerges on a robotic manipulator when the wrist IMU fails?
A)Unstable end-effector orientation control✓
B)Increased power consumption of actuators
C)Sudden joint angle limit violations
D)Unpredictable cycle time fluctuations
💡 Explanation
Without reliable IMU data, the control system cannot accurately calculate wrist orientation; this results in unstable end-effector orientation control due to error accumulation during inverse kinematics because closed-loop sensor feedback is disrupted. Therefore, orientation becomes unstable rather than power draw fluctuating, which is usually linked to motor strain.
