By rocky, I’m not talking about pebbles and small stones. I’m referring to boulders and ledge that may need blasting. It happens quite often up here and most of the time excavators may not know about these issues until they start digging.

That’s not how it works. Either the surrounding property needs to be regraded, in which case you’d still be forced to use excavation equipment, or you’re making an even more complex machine to be able to support building things like walk out basements on a custom grade. In the case of basements there’s simply a lot of volume of material that would need to be either removed out of a lot or just moved within the lot. Again, still needs excavation equipment to do that. The same excavation equipment that can dig out a foundation within hours and is perfectly adept at dealing with boulders.
A machine to handle other parts of the job such as foundation pouring might be viable. I’m just saying that a magical machine that can do it all if left alone for a few days is wishful thinking.
