← TechnologyWhich hazardous outcome occurs when phase differences reduce feedback sensor accuracy in robotic arm servo control?
A)Oscillation due to cumulative latency✓
B)Mechanical seizure from encoder wraparound
C)Thermal runaway in motor windings
D)Corrosion weakening structural integrity
💡 Explanation
Oscillation results when phase differences introduce cumulative latency via proportional control; the controller overreacts because the actual position lags the intended position. Therefore, the arm oscillates, rather than achieving stable positioning, due to accumulated sensor error.
