← TechnologyWhich 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.
