Effects of Temperature

Battery Unit

• The heater is a 72-volt unit. It is primarily used to defog the windshield. Using it will rapidly deplete the batteries, shortening your range.

Our Future Building Plan

Future Development

• More testing• Strength of materials

Possible Future Ideas

• Explore ways to turn the motion of crank into turning power for the arm using some form of gear

• Build a model of the Zap car and arm for small scale testing

Conclusion

Our idea provides a simple, reliable, and cheap solution to moving the car into the bat cave
