Taking into account the complexity and compatibility of this project, I have decided to make a battery car, converting chemical potential energy to kinetic energy.
Here is a diagram showing how to circuit one battery to a switch and two motors.
Here are the videos I took reference from:
The video above demonstrates the basic process of constructing a battery car utilizing rubber bands to connect the motor to the back wheel. It also shows the fundamental circuiting of this project including different applications of components.
Safety Concerns:
- confirm the compatibility of the wires and motors being used to consolidate the stability of the circuit, some may be too thin
- Use the appropriate tools while making the toy car
- Conceive a safe way to cool the easily-overheated battery
- Secure the wires with materials such as electric tape to prevent any detachments
- Conceive a safe way to substitute the overheated battery (Placing a box above the car?)
Success Criteria:
- Construct a toy car that can sustain forward movements for at least 10 seconds
- The circuit/battery is safe to handle with
- The car entertains people (Positive feedbacks)
Materials:
1 battery (9V)
1 thin metal rod (14cm)
Two DC motors
Positive and Negative Wires
A wooden board (20cm by 10cm)
4 wheels
A straw (10cm)
