How to Fix / Troubleshooting
Safety first: Turn the robot OFF before inspecting wheels.
Steps:
- 1. Clean wheels: Remove dust and hair from the drive wheels and their axles. Ensure the rubber treads are clean and dry.
- 2. Check wheel movement: Rotate each wheel by hand and compare resistance. If one feels significantly stiffer, clean around its axle and suspension.
- 3. Test on flat surface: Run the robot on a flat, uniform surface and observe its path.
When to call a technician: If the robot continues to circle or veer strongly to one side, the wheel encoder or motor may be defective and require professional replacement.
