So the idea is that you don't need to specialize it to the thing it's meant to work on, because it works on whatever a human works on. A similar idea drove a lot of the DARPA Robotics challenge, with its emphasis on being able to drive a normalish vehicle, open a door, climb a ladder, use a regular power tool, etc.

Anyway, I think the state of the art for all this is still pretty far away, which is why the instinct is to assume we're talking about something specialized.
