← TechnologyWhich navigational error arises when a robotic lawnmower experiences wheel slippage on wet grass?
A)Erroneous odometry calculations✓
B)IMU data saturation
C)GPS coordinate drift
D)Excessive Kalman filtering
💡 Explanation
Wheel slippage causes the mower's internal revolution counters to overestimate distance traveled via odometry, because the shaft encoders detect motion where actual ground displacement is less. Therefore, the navigation system incorrectly updates the mower’s perceived location rather than using alternate sensors.
