Each manual covers specific models:
- Manual 1: Typically covers the Bulldozer and other initial models.
- Manual 2: Covers the Robot and other complex models.
Carefully identify the required pieces for each step and ensure they are securely connected. The modular design allows for easy disassembly and reassembly to create different models.
Operating Instructions
Your LECPOP STEM Robot Toy offers multiple control modes for dynamic play.
1. Remote Control Mode
Use the included physical remote control for direct operation. The remote features two joysticks, each controlling one track of the vehicle. This allows for precise movement, including forward, backward, and turning by moving the tracks independently.

Figure 6: The remote control allows for direct manipulation of the model's tracks, enabling movement and steering.
2. Mobile App Control Modes
Connect your smartphone via Bluetooth to unlock advanced control and programming capabilities through the LECPOP app.
- Remote Control Mode: Control direction using on-screen buttons, similar to the physical remote.
- Gyro Mode: Control the model's movement by tilting your phone.
- Driving Simulation: Experience a virtual driving interface for controlling the model.
- Navigation Path Mode: Draw a path on your screen, and the model will follow it.
- Programming Mode: Program custom movements and actions using a visual block-based coding interface, fostering STEM learning.

Figure 7: The mobile app provides diverse control options, from direct remote control to advanced programming and path following.

Figure 8: The programming mode within the app allows users to create custom sequences of movements for the robot.
Special Feature: Moving Pistons
A notable mechanical feature of the models is the functional pistons, which move realistically as the tracks operate, adding to the immersive engineering experience.
Maintenance
- Cleaning: Use a soft, dry cloth to wipe down the models and remote control. Avoid using water or harsh chemicals.
- Battery Care: Ensure the rechargeable battery is fully charged before each play session for optimal performance. When storing for extended periods, charge the battery to about 50% and remove AAA batteries from the remote control to prevent leakage.
- Storage: Store the building blocks and assembled models in a cool, dry place away from direct sunlight to prevent material degradation.
- Component Check: Periodically check all connections and ensure no pieces are loose or damaged. Replace any broken parts if necessary.
