Black Darkness Car

Tech Specs
Power: Power Fuctions
Steering: Extended steering shaft
Parts: 
Lego® Ev3 Expansion Set 45560 - New
5x Big Black Gears (optional)
Several parts for the extendable drive shaft
You "can" use a different colors but it won't look as good:
1x Red 11M
4x Black 15M
2x Black 13M
4x Black 9M
3x Black 7M
2x Black 5M
8x Black 3M
How it Works
The motor is at the bottom of the photograph facing to the 20 teeth gear, connected to the differential. Then the wheels are attached to the wheels.
The battery box is in the main body. The lights are attached to that along with the M-Motor and the black brick is the block half way down the "light" wire.

The extendable drive shaft.

The "extendable drive shaft's" goes through two universal joints to a handle that moves a handle that steers the car.

Lego Mindstorms EV3 Forklift



Data Sheet:
Power:  Mindstorms Ev3 (1x Ev3 Med. Motor and 2x Ev3 Large Motors)
Drive: 1x Ev3 large motor.
Parts: Lego® Ev3 Expansion Set 45560 - NewLEGO® Mindstorms EV3 31313
 and , 2x 16 tooth gears (OldNew), White 3M Beam (Color Matters), and Lego Mindstorms Ev3 31313

How it works
This is the remote. There is an Ev3 Color sensor on the left side of the remote. Their is a black element that can slide on and axle left and right. This will make the color sensor see the different colors, therefore steering the car. The downside of this steering method is that it must have a wire running from the sensor to to the brick.
This is the "Tire Lock" it locks the tire in place when the tire is more than 1 stud off the ground. This is pulled off by an axle that when it is touching the ground it will lift the black axle coming of the top witch is connected to a beam that connects to an axle that is lowered into the rim of the tire. This will keep the tire from falling off.

Build It Yourself
You will need the parts listed from the kits above. I split the build into 5 "bags" just like real Lego sets:
Bag 1: The steering system
Bag 2: The arm/ body
Bag 3: The drive system
Bag 4: The Remote Control.
Bag 5: The Tires to pick up

Simple Car - How to Add Power Fuctions

You like the Simple Car, but hate to keep turning that knob to make the car go. If you have the LEGO® Technic Power Function Accessory box (8293) and Lego® Ev3 Expansion Set 45560
 you can upgrade simple car to a whole new level with power functions.
The motor is just added instead of the handle and the battery box is stuck on top.

How to build it yourself
These are the parts you will need in addition to the parts from simple car.

Then watch this "Build with Boston" tutorial.
