5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your robot car kit.
- Cleaning: Regularly clean the chassis and wheels with a soft, dry cloth to remove dust and debris. Avoid using liquids directly on electronic components.
- Battery Care: If not in use for extended periods, remove the 18650 battery to prevent leakage. Store batteries in a cool, dry place.
- Component Inspection: Periodically check all connections and wiring for looseness or damage. Ensure sensors are clear and unobstructed.
- Storage: Store the robot car in a dry, cool environment away from direct sunlight and extreme temperatures.
6. Troubleshooting
If you encounter issues with your robot car, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Robot does not power on. | Battery not installed, low battery, incorrect battery polarity, loose power connection. | Ensure 18650 battery is installed correctly and charged. Check all power connections. |
| Motors not responding. | Incorrect wiring to motor driver, faulty motor driver, programming error. | Verify motor wiring according to the tutorial. Check your code for motor control commands. |
| Sensors not detecting. | Sensor wiring incorrect, sensor obstructed, programming error. | Check sensor connections. Ensure sensors are clean and unobstructed. Review sensor reading code. |
| App control not working. | Bluetooth not paired, app not connected, incorrect firmware on Micro:bit. | Ensure Bluetooth is enabled on your device and the robot. Follow app pairing instructions. Upload the correct firmware for app control. |
