Shovel snow like a human as in make a plan and deal to the snow with the least amount of shifting snow twice? That's almost up at the coffee test level.of cognition. You could give it instructions and it might do not a too bad of a job if you stood there making sure it wasn't making more work for you than it was saving. It wouldn't do to be taking chunks out of the shrubbery, or your car.
Lawn mowing is covered by autobot mowers already. I know a guy with two. One for each side of his driveway so they never need supervision to cross the road.
A security guardbot could "foot patrol" a route inside fence already I think. It could even chase after an intruder if you gave it enough sensing.
What it is going to take some time yet is having the "security guard" able to reason with an intruder or apply consequences for failure to comply with instructions.
AI can make a reasonable impersonation of an actual human. For all I know, you could be one!
