This robot will have four wheel drive, four wheel steering, and four wheel independent suspension.

The large things at the front and back control the steering.
They use clutch gears and worm gears.

It will have two motors connected to a worm gear and 24-tooth gear to control the the drive.

It uses many peices from 8466.
To make the suspension+drive+steering I followed the instructions for the front end of 8466 2x. 

I am currently planning to use the scout the power it.
