If this is actually going to drive on the Moon, what I’d do is dust-off the RATLER proposal from Sandia National Labs. This was a proposed rover for the Moon or Mars that was developed by Sandia in the 1990s They got as far was driving full-sized rovers in the dessert.
The key concept or idea is that “The Chassis IS the Suspension”. There is no separate suspension that is bolted to a chassis. This eliminates most of the parts and is much stronger too.
The major risk, I think, is driving into a hole either with the entire vehicle or just one wheel in a “hole” between a pair of rocks. The one thing that really matters is the wheel diameter. Be as smart as you like with rover design and it matters less than simply having bigger wheels. So for a given mass, the Ratler has larger wheels than a Mars rover. The other thing Ratler has is simplicity. There is very little that can go wrong. The rover is just four wheels and a central pivot axel. and impotently all the parts are inside a strong shell.
I’ve been (slowly) working to develop a Ratler clone that can be 3D printed. My goal is that I want it larger than 1/2 meter wheelbase and strong enough to tumble down a full flight of stairs front over back. This last part has forced a redesign using larger axels and wheel bearings.
One thing both Mars Rover and Ratler have in common is a guarantee of equal weight on each wheel. This dramatically improves traction but they are at opposite ends of the complexity spectra. The Mars rover is the most complex design possible white Ratler is the simplest possible for equal weight distribution.
Have a look. Sandia did much of the work already and their papers show the optimal geometry and this has been tested at different scales. They are also cheap to build even at one meter wheelbase size.
