General Assembly Tips:
- Part Preparation: Carefully detach each piece from its plastic frame using a wire cutter or small hobby knife. Ensure all excess plastic is trimmed to allow for smooth movement and proper fit.
- Follow Diagrams: Refer to the detailed diagrams in the instruction manual for correct part orientation and connection points. Each part is labeled for easy identification.
- Gear Alignment: Pay close attention to gear alignment to ensure smooth operation of the robot's mechanisms.
- Testing: After assembling the core motor and solar panel unit, test its functionality in direct sunlight before completing the entire robot.

Operating Instructions
The robots in this kit are primarily powered by a solar panel. Ensure the solar panel is exposed to sufficient direct sunlight for optimal performance. Alternatively, some models may support battery power (not included) for indoor or low-light operation.

How Solar Power Works:
- Sunlight hits the solar panels, creating an electric field.
- The generated electricity flows to the edge of the panel and into a conductive wire.
- The conductive wire brings electricity to the inverter, where it is transformed from DC to AC, powering the robot.

Movement Capabilities:
Depending on the model built, your robot can exhibit various movements, including crawling, rolling, and even floating on water (for specific models like the Surf-bot or Row-bot).

Maintenance
- Cleaning: Wipe down plastic parts with a soft, dry cloth. Avoid using harsh cleaners or solvents.
- Solar Panel Care: Keep the solar panel clean and free of dust or obstructions to ensure efficient power generation.
- Storage: When not in use, store the robot and its components in a cool, dry place away from direct sunlight to prevent material degradation.
- Disassembly: Parts can be disassembled and reassembled to create new robot models. Handle with care to avoid breakage.
Troubleshooting
- Robot Not Moving:
- Ensure the solar panel is in direct, strong sunlight.
- Check all wire connections to the motor and solar panel.
- Verify that all gears are properly aligned and rotate smoothly without binding.
- If using battery power (for compatible models), ensure the battery is correctly installed and charged.
- Parts Not Fitting:
- Double-check the instruction manual for the correct part and orientation.
- Ensure any excess plastic from the sprue has been completely trimmed from the part.
- Some connections may require gentle but firm pressure. Avoid excessive force to prevent breakage.
- Difficulty with Assembly:
- The assembly process can be challenging. It is recommended that parents and children work together, especially for younger users.
- Refer to the detailed diagrams and step-by-step instructions carefully.
