Arduino or Romeo ? How to adress 4 wheels/motors ?

Hello,

I want to create a robot with 4 wheels that would be able to progress through a labyrinth and wouldn't cost too much (it's for a club).

Should I use an Arduino or should I use a Romeo All in one Controller ?

Is it possible to adress/work/direct 4 wheels/motors with either one of this two processors without additional cards ?

Which additional should I add If I need to add one ?

Regards.
