← TechnologyWhich consequence results when sensor fusion deviates significantly between multiple ultrasonic sensors in autonomous robot navigation?
A)Path oscillation near obstacles✓
B)Reduced power consumption overall
C)Increased accuracy of motor control
D)Simplified odometry calculation cycle
💡 Explanation
Path oscillation occurs because Kalman filtering gives increased weight to erroneous data, producing unstable velocity commands for the robot's drive motors, therefore the robot navigates with oscillating paths, rather than smoothly avoiding the obstacles due to sensor miscalibration.
