Assembly Instructions
The Wesfuner 30-in-1 Solar Robot Kit allows for the construction of 30 unique robot models. Each model has specific assembly steps detailed in the included instruction manual. It is recommended to follow the manual's diagrams carefully for successful construction.
- Preparation: Carefully remove all plastic parts from their frames. Use small snips or clippers for clean removal, avoiding stress on the connection points. Sort and label parts as indicated in the manual to simplify the building process.
- Robot Body Assembly (Gear Drive): Begin by assembling the core gear drive mechanism as shown in the manual. Ensure all gears are properly aligned and move freely.
- Robot Head Assembly (Power Supply): Assemble the robot head, which houses the solar panel and the battery compartment. Connect the wires from the solar panel and motor to the designated points.
- Test the Gear for Normal Drive: Before fully enclosing the mechanism, perform a quick test to ensure the motor and gears function correctly.
- Complete the Model: Attach the remaining accessories, wheels, tracks, or other specialized parts according to the specific robot model you are building.

Operating Instructions
Once your robot is fully assembled, you can bring it to life using either solar power or battery power.
Solar Power Mode:
- Ensure the solar panel is clean and free from obstructions.
- Place the robot in direct sunlight. The solar panel will convert sunlight into electrical energy to power the motor.
- The robot will begin to move when sufficient sunlight hits the solar panel. Performance may vary based on sunlight intensity.
Battery Power Mode:
- If playing indoors or on cloudy days, insert one AAA battery (not included) into the designated battery compartment in the robot's head.
- Ensure the battery is inserted with the correct polarity (+/-).
- The robot will now be powered by the battery and can be operated indoors.

Maintenance
- Cleaning: Use a soft, dry cloth to wipe down the robot and solar panel. Avoid using harsh chemicals or abrasive materials.
- Storage: When not in use, store the robot and its components in a cool, dry place away from direct sunlight to prevent material degradation. If using battery power, remove the AAA battery before long-term storage.
- Inspection: Periodically check for any loose connections or damaged parts. Replace any broken components to ensure safe and proper operation.
Troubleshooting
- Robot does not move (Solar Mode):
- Ensure the solar panel is exposed to direct, strong sunlight.
- Check that all electrical connections are secure.
- Verify the solar panel is clean and free of dust or obstructions.
- Robot does not move (Battery Mode):
- Check if the AAA battery is inserted correctly with the right polarity.
- Replace with a fresh AAA battery.
- Ensure all electrical connections are secure.
- Parts are loose or fall off:
- Re-examine the assembly steps in the manual to ensure all parts are securely attached.
- The kit features reinforced assembly holes and accurate track design to minimize this issue.
