The robot part exists, the hard part is the intelligence for that robot to be autonomous.

Stuff like this is already available as a standard industrial product: https://www.hilti.com/content/hilti/W1/US/en/business/busine...

Giving a robot proprioception, balance, or even good enough vision to reliably position itself (tracks, wheels, or limbs) without crashing through soft ceilings underneath it, or failing to recognise the correct spot to putting the tool, that's what's currently really only good enough for a tech demo rather than an product you'd want to buy/hire.
