6 wheels are good for heavily rocky terrains, but is complex to steer. Higher mass and power consumption since you need to drive 6 motors.
The 2 wheel concept is lightweight and can turn in place but it could easily get stuck by obstacles; the body has to be below the wheel axis.
4 wheels is a good all-round solution. WRV1 is clever solution; it achieves steering by bending the body, so you don't have to rotate the wheels, which would add extra complexity.
By "no brushings", do you mean no bushings?

I edited the video so it's my fault if there is any mistake ;-)
To be honest, I think it refers to "brush-less motor" and not bushings but I'm really not sure. Certainly the word brushing seems incorrect.

Yeah, brushless motor makes sense. Thanks.

Beware of those lunar sticks jamming the rover! ^_^
Nice editing and music choice.

What's the trade off between two, four, and six wheels?
