They're very smartly having this work as a tractor attachment so they're not reinventing the literal wheels. For small farms, a scaled-down version could be pushed along like a wheelbarrow or attached to something like an ATV or ride-on mower.

But at the home garden scale, I'd like to see a dog-sized spider-like robot that would roam the block doing this. It can be very hard to keep soil weed free, and then weed it once it isn't.
