WRV1 Lunar Rover Off Road

Jörg took his WRV1 rover prototype out to do some off road testing. Sorry for the shaky pictures; it's not easy to record video and control the rover at the same time. The rover design and blueprints are available at http://bit.ly/wrv1

Yeah, brushless motor makes sense. Thanks.

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.

[zavatone]

By "no brushings", do you mean no bushings?

Beware of those lunar sticks jamming the rover! ^_^

Nice editing and music choice.

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.

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

Awesome!
