Introduction
The Yutin 5-in-1 STEM Robot Kit provides an engaging and educational experience for children aged 8-12. This kit includes components to build five distinct robot models: a Doodling Robot, a Reptile Robot, a Balance Car Robot, a Rope Climbing Robot, and a Walking Robot. Designed to introduce fundamental concepts in Science, Technology, Engineering, and Mathematics (STEM), this kit encourages hands-on learning, creativity, and problem-solving skills.
By assembling wooden puzzles, motors, circuits, gears, shafts, and screws, children will develop practical skills and enhance their self-confidence. Each robot offers unique features and functions, making the building process both challenging and rewarding.
Safety Information
WARNING: This toy contains small parts and functional sharp edges and points. Not suitable for children under 3 years of age. Adult supervision is required during assembly and play to ensure safety and proper use of components.

Operating Instructions
Once assembled, each robot can be operated according to its unique design. Ensure batteries are correctly installed before activation.
- Doodling Robot: This robot is designed to draw patterns as it moves. Attach pens to its designated holders and place it on a flat surface to observe its artistic movements.
- Reptile Robot: Mimics the movement of a reptile, crawling forward with segmented body parts. Activate its motor to see it slither across surfaces.
- Balance Car Robot: Utilizes principles of balance and center of gravity to move on two wheels. Observe how its design allows it to maintain stability while in motion.
- Rope Climbing Robot: Designed to ascend a rope. Securely attach the robot to a taut rope and activate its mechanism to watch it climb.
- Walking Robot: Features articulated legs and arms that allow it to walk. Activate the motor to observe its bipedal movement.

Maintenance
To ensure the longevity and proper function of your Yutin STEM Robot Kit, follow these maintenance guidelines:
- Cleaning: Wipe down wooden surfaces with a dry, soft cloth. Avoid using water or harsh chemicals, as they may damage the wood or electronic components.
- Battery Care: Remove batteries from the battery holder when the robots are not in use for extended periods to prevent leakage and corrosion.
- Storage: Store the assembled robots and any unused components in a cool, dry place away from direct sunlight and extreme temperatures.
- Component Check: Periodically inspect all connections, wires, and moving parts to ensure they are secure and free from damage. Tighten any loose screws as needed.
Troubleshooting
If your robot is not functioning as expected, consider the following troubleshooting steps:
- Robot Not Moving:
- Check if batteries are correctly inserted and fully charged.
- Ensure all wires are securely connected to the motor and battery holder.
- Verify that the motor switch is in the 'ON' position.
- Inspect for any obstructions preventing movement of gears or wheels.
- Intermittent Functionality:
- Loose connections are a common cause. Re-check all wiring and ensure firm contact.
- Weak batteries can lead to inconsistent performance. Try replacing them with new ones.
- Parts Not Fitting:
- Refer back to the specific robot's instruction manual to confirm the correct orientation and sequence of parts.
- Ensure no small debris is obstructing the connection points.
