Left or Right Wheel Module
The differential drive system requires matching RPM feedback from both wheels to maintain a straight path. If one motor fails or its internal optical encoder is obscured by dust, the control board senses a stall and attempts to pivot away from the perceived obstacle. Replacing the faulty module restores the closed-loop feedback required for synchronized rotation.

Floor Tracking Sensor
The i7 uses an optical floor tracking sensor (similar to a computer mouse) on its underside to calculate distance and heading via SLAM navigation. If the lens is scratched or the internal LED fails, the robot loses its ability to track movement across the floor surface, leading to erratic spinning as it attempts to re-localize.
