Precautions for Use

• This quadruped robot kit is not a toy. Teenagers should use it under adult or teacher supervision.
• Use proper battery management – avoid short circuits, overcharging, and over-discharging.
• Ensure servo travel ranges do not exceed the mechanical joint limits to avoid stalling and burning motors.
• High-torque servos can pinch fingers – keep hands clear during operation.
• Always observe correct polarity when connecting servos and power.
