← TechnologyWhich outcome occurs when a robot arm's inertial measurement unit (IMU) fails to provide accurate angular velocity data?
A)Joint trajectory deviates from commanded✓
B)PID loop oscillations dampen prematurely
C)Encoder resolution becomes artificially limited
D)DC motor torque output is maximized
💡 Explanation
Trajectory deviation occurs because the inverse kinematics depends on accurate angular information through data fusion using a Kalman filter for precise positioning; therefore, positional accuracy declines rather than oscillation damping which relies on feedback from encoders and motor control.
