What an excellent question. I'm very much interested in the answer as well. On a similar note, I read on Twitter a robotics expert talking the other day about how we can probably get robots that can recognize and pick up basic objects, moving them from one location to the next. One great application of this would be a robot that picks up toys and socks that children leave behind into a chest or something of the sort. I think lots of parents would enjoy that.
