As for motors, you don't need 4 motors with 6 wheels, 2 would be just fine. When selecting the number of motors you are looking to see how much power you want. The more motors, the more power, the more complexity.

So 6 wheels is more complex than 4, but has better qualities. And 4 motors has more power and more complexity. It all depends on what you and your team feel comfortable with designing and building.

Personally though, I would go 6 wheels and 4 motors.
6 wheels doesn't mean more traction than 4. It only means less force per unit area trying to tear up the carpet. The main advantage of 6 wheels is that they can turn better than 4 wheels, since in a 4 wheel design, two of the wheels have to sideslip somehow.
