Oh yea and how are you going to program that thing to go sideways? when hinges are closed it can go forward and backward but when you open the hinges and wheels are 180 degrees, wouldn't each side try to fight against each other?

I don't believe that the casters would cause a noticeable amount of friction.
Now, for programming it to go sideways, you could just program it with tank drive and make the x-axis on the joysticks move the robot side to side when it is open.
