How to Fix / Troubleshooting
Safety: Turn OFF the robot and flip it over.
- 1. Clean wheel housings:
- Remove debris, hair, and dust from both drive wheel wells.
- 2. Check wheel rotation:
- Spin each wheel by hand; they should feel similar in resistance.
- 3. Test on open floor:
- Run the robot on a flat, open area and observe its path.
- 4. Swap wheels (advanced, if identical modules):
- If possible, swap left and right wheel modules to see if the behavior changes sides.
- 5. Replace faulty wheel:
- If one wheel is clearly weaker or noisy, replace that wheel motor assembly.
