4. Assembly Instructions
Each of the five STEM projects comes with its own detailed, step-by-step instruction manual. It is highly recommended to follow these instructions carefully for successful assembly. A mini screwdriver is included to assist with the assembly process.
General Assembly Tips:
- Read First: Before starting, read through the entire instruction manual for the specific project you are building to familiarize yourself with the steps and components.
- Organize Parts: Lay out all components for the chosen project. The parts are often small, so keeping them organized will prevent loss and confusion.
- Follow Diagrams: Pay close attention to the diagrams and illustrations provided in the manual. They are crucial for understanding component placement and connection points.
- Secure Connections: Ensure all electrical connections are secure and all screws are tightened appropriately. Loose connections can prevent the model from functioning correctly.
- Adult Assistance: For younger children (8-9 years old) or if difficulties arise, adult assistance and supervision are strongly recommended, especially with small screws and intricate steps.

5. Operating the Models
Once assembled, each STEM model operates based on basic electrical circuits and mechanical principles. Ensure batteries (not included) are correctly inserted into the designated battery compartments with the correct polarity.
Specific Model Operations:
- Doodle Robot: This robot uses a vibrating motor to move randomly, causing attached pens to draw patterns on a surface. Ensure pens are securely attached and have ink.
- Aircraft Car: Powered by a DC motor, this model uses a propeller to generate thrust, allowing it to move forward. Verify the propeller is securely fastened to the motor shaft.
- Mini Conveyor: This model demonstrates the principle of a conveyor belt using a motor and gears to move objects along a track. Ensure the belt is properly tensioned and aligned.
- Ferris Wheel: A motor drives the rotation of the Ferris wheel, illustrating rotational motion. Check that all connecting rods and seats are properly secured.
- Tracked Tank: This tank uses two motors to drive its tracks, allowing for movement and turning. Ensure tracks are correctly fitted onto the wheels and sprockets.

6. Care and Maintenance
To ensure the longevity and proper functioning of your Poraxy STEM Science Kits, follow these care and maintenance guidelines:
- Cleaning: Wipe down models with a dry, soft cloth. Avoid using water or cleaning solutions directly on electronic components.
- Storage: Store assembled models and unused components in a dry, cool place away from direct sunlight and extreme temperatures. Keep them in their original packaging or a designated storage container to prevent loss of small parts.
- Battery Removal: Always remove batteries from the models when not in use for extended periods to prevent battery leakage and corrosion.
- Handle with Care: While designed for durability, avoid dropping or applying excessive force to the models, especially on delicate parts like propellers or wires.
7. Troubleshooting
If you encounter issues with your Poraxy STEM Science Kits, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Model does not move or operate. | Incorrect battery insertion, dead batteries, loose wiring, motor malfunction. | Check battery polarity and replace with fresh batteries. Inspect all wire connections for tightness. Ensure motor is properly seated and connected. |
| Parts do not fit together or assembly is difficult. | Incorrect part orientation, misidentification of parts, tight tolerances. | Refer to the detailed instruction manual's diagrams. Ensure you are using the correct part for the step. Apply gentle, even pressure. Adult assistance may be required for small or tight components. |
| Belts or tracks frequently pop off. | Improper tension, misalignment, worn parts. | Ensure belts/tracks are correctly aligned on pulleys/sprockets. Check for proper tension; they should be snug but not overly tight. Inspect for any obstructions or damaged parts. |
| Instructions are unclear. | Complex step, small diagrams. | Review the step multiple times. Look for subtle details in the diagrams. Seek assistance from an adult or someone with experience in similar kits. Online resources or videos (if available from Poraxy) might offer additional visual guidance. |
