To build a barrier gate working model using a robo motor, car toy big wheel, paper straw (as the gate), and a 9V battery, follow these step-by-step instructions.
This model demonstrates how barrier gates work, using basic materials and a DC motor to simulate the lifting and lowering of road gates at crossings or parking lots!
This model simulates a road gate system like those seen at parking lots, toll booths, or railway crossings.
Materials Needed:
- Robo motor (DC geared motor)
- Car toy big wheel (to rotate the gate)
- Paper straw (as the barrier gate)
- 9V battery
- Switch (to control the gate)
- Wires
- Cardboard or wooden base (for mounting)
- Hot glue, tape, or screws (to secure components)
Video Steps to Build the Barrier Gate:
1. Prepare the Base:
- Create a sturdy base using cardboard or wood to mount the components. This will act as the foundation for your barrier gate system.
- Mount the robo motor securely on one side of the base using hot glue or screws.
2. Connect the Car Toy Big Wheel to the Motor:
- Attach the car toy big wheel to the shaft of the robo motor. This wheel will act as a lever to help lift and lower the paper straw gate.
- Make sure the wheel is fixed tightly to the motor shaft so it turns smoothly when the motor is powered.
3. Attach the Paper Straw Gate to the Wheel:
- Fix the paper straw to the edge of the big wheel using glue or tape. The straw will act as the barrier gate that moves up and down as the wheel rotates.
- Position the straw horizontally so that when the wheel turns, it lifts and lowers the straw (gate).
4. Wiring the Motor:
- Connect the robo motor to the 9V battery using wires.
- Place a switch between the battery and motor to control the motor’s power. This will allow you to raise or lower the gate manually.
5. Testing the Model:
- Turn the switch ON. The motor will rotate the car toy wheel, which will raise the paper straw (gate) upward.
- When you turn the switch OFF, the motor will stop, and the gate will lower back down, closing the road.
6. Fine-Tuning:
- Ensure the length of the straw gate is appropriate to cover the imaginary road in your model.
- Adjust the speed of the gate by choosing a suitable robo motor. A slow-speed motor will give a smooth gate movement, while a high-speed motor will open/close the gate quickly.
How It Works:
- The robo motor is the driving force in the system. When powered by the 9V battery, it rotates the toy car wheel.
- The car toy wheel, acting as a lever, lifts the paper straw attached to it.
- The switch allows you to control the movement of the gate, simulating a real-life road barrier that opens to allow cars through and closes to block the road.
