Very interesting

I have seen a few of these, but only one (about a decade ago) that used legs not wheels

Wouldn't it be better if the robot walked rather than rolled?

You may be able to illuminate this for me...

Before we started building we considered many different designs, including legs. However, it introduces significant extra mechanical and control complexity, with more complex failure modes - e.g. one leg gets stuck in the mud; it also would be more expensive to build.

So we decided to stick with wheels, at least for this product iteration!
