My Vehicle by "a car killer"

After "killing" three toy cars, I finally understand how they work with motor. Then I re-used their parts to build my vehicle.

1) First Version = A"blind" Vehicle
When I connect the power, the vehicle will start to move.

2) Second Version
I used touch sensor to control the vehicle.
In the beginning the vehicle is motionless. If the users press the sensor, the vehicle will start to move from one place to another.
