← TechnologyWhich accuracy risk increases during rapid robotic arm movements?
A)Encoder quadrature signal phase shift✓
B)Excessive controller proportional gain
C)Actuator ferromagnetic core saturation
D)Inertial navigation system drift accumulation
💡 Explanation
Encoder quadrature signal phase shift becomes significant because inertia during rapid movements exceeds the encoder's processing capability, leading to inaccurate positional data; therefore position control degrades, rather than other unrelated electronic or saturation effects.
