The making

Step 1

Hold a wheel into your left hand and a geared motor in the right hand. Keep the motor in a way so the black head points opposite to you and the motor wire faces your right palm.
Push the motor shaft into the shaft slot of the wheel. You will have to match the flat and curved surfaces of the shaft and the slot.
This is your car’s left side wheel.

Step 2

Now prepare your car’s right side wheel. Hold another wheel into your right hand and a geared motor in the left hand. Keep the motor in a way so the black head points opposite to you and the motor wire faces your left palm.

Push the motor shaft into the shaft slot of the wheel and the right side wheel is ready.

Step 3

The place where you see the Havi logo is the top front portion of the car. You need to start working on the opposite side, i.e. the bottom.

Step 4

Stick a piece of double side tape on the motor slot given at rear bottom. Match the edges of the tape and motor slot. Let the preventive paper be there for now.

Step 5

Stick tape piece on the second motor slot.

Step 6

Stick a piece of the tape at the front bottom as it comes below the Havi logo.

Step 7

Peel off the paper of the tape at the left side slot and stick the motor of the left wheel there. Make sure the edges of the plate, tape and motor are matched.

Step 8

Peel off the paper of the tape at the right side slot and stick the motor of the right wheel there. Make sure the edges of the plate, tape and motor are matched.

Step 9

At last, peel off the paper of the tape at the front bottom and stick the roller there. The mechanics of your car are ready.

Step 10

Prepare the circuit for the function you want to achieve. Let’s take the most basic car that can be driven by Power and 2 motor elements. Snap them and connect the power bank.

Step 11

Put a couple of small pieces of double tape at the top and stick the circuit and power bank. (You can put the tape pieces on the elements as well, instead of the plate) Now connect the motor wires with motor elements.

Your car is ready to go. Turn the power on and it will zoom on the floor.

How does it work?

The power element does supply the current to motor elements. The motor elements supply the current to geared motors which will rotate the connected wheels.

Wheels will rotate together to force the car to move. The roller will reduce the friction and will help the car to move smoothly.

This is the fundamental principle behind an electric car. Kids can submit this car project to school and science fairs.
