Which 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.
