Chariot: The FIRST Lunar Truck

I must be missing something?

Why would a lunar truck need a crab drive?

While this looks very cool and I would like to have one; it does not seem practical.

I think the engineers had a bit too much fun designing this.

Nice Name for a vehicle. Dr. Smith would be proud.

It's not just a crab drive. It's a crab drive with independently-steerable wheels, each wheel set having separate suspension and separate speed control. For driving a large vehicle on absolutely unprepared terrain, it's among the best options. It gives very good maneuverability, traction, and speed.

I remember seeing this when I visited Johnson this summer. Though at that stage they'd only built one or two of the legs for it. The RoboNaut's shop was pretty cool too
