Setup and Assembly Guidelines
Before beginning assembly, ensure you have a clean, well-lit workspace. It is recommended to work on one model at a time to avoid mixing parts. Refer to the detailed instruction manual for step-by-step guidance for each specific robot.
- Unpack: Carefully open the main box and identify the instruction manual and the two screwdrivers.
- Select a Model: Choose one of the six robot models you wish to build first. Locate the corresponding numbered bag (e.g., "Model 1: Fiber Optic") and its components.
- Battery Installation: Most models require 2 AA batteries (not included). Install them into the designated battery holder according to the polarity markings (+/-).
- Follow Instructions: Use the provided detailed instruction manual for step-by-step assembly. Each step is illustrated to make the process clear.
- Secure Connections: Ensure all wires are securely connected and screws are tightened appropriately using the provided screwdrivers.

Operating Instructions
Once assembled, each robot offers a unique interactive experience. Ensure batteries are correctly installed before attempting to operate any model.
Model 1: Fiber Optic Lamp
This model demonstrates light transmission through fiber optics. After assembly, connect the battery pack. The fiber optic strands will illuminate, creating a colorful light display.

Model 2: Reptile Robot
The Reptile Robot is designed to mimic the movement of a reptile. Once assembled and powered, its unique wheel design allows it to crawl and navigate surfaces. Observe how its motion is generated by the motor and gears.
Model 3: Balance Car
This two-wheeled vehicle is engineered to maintain balance while moving. Power it on and watch it demonstrate principles of stability and motion. It may require a flat, smooth surface for optimal performance.
Model 4: Bubble Machine
Create a fun bubble display with this machine. Fill the reservoir with bubble solution (not included). Power on the machine, and the fan will rotate the bubble wands through the solution, producing a stream of bubbles.

Model 5: Doodling Robot
Attach pens to the robot's legs, place it on a large sheet of paper, and power it on. The robot's vibrating motion will cause the pens to draw unique patterns and designs as it moves randomly across the surface.

Model 6: Sliding Plane
This model simulates a propeller-driven vehicle. Once assembled, power it on, and the propeller will spin, generating thrust to move the plane across a smooth, flat surface.
