Which unintended robot behavior results when sensor fusion improperly weights an unreliable ultrasonic sensor's input due to persistent ambient noise?

A)Unstable positional PID loop gain
B)Spurious obstacle avoidance maneuvers
C)Localized thermal runaway in driver
D)Encoder count saturation and rollover

💡 Explanation

Spurious obstacle avoidance occurs because sensor fusion interprets corrupted ultrasonic data, giving it undue weighting due to failed validation. Therefore, the robot reacts to non-existent obstacles, rather than maintaining its path using other sensor data.
