This was essentially Willow Garage's pitch with the PR2, like a decade ago. Obviously they were several orders of magnitude off on the price point, but that was the idea— an "appable robot" with standard hardware that everyone would rush to write new capabilities for.

The home is always going to be a nightmare environment for this kind of thing, though— even without the mundane issues of stairs, doorknobs, appliances with varying interfaces, and hazards like pets and clutter, there's just far too much breadth of potential tasks to want it to do.

Later companies understood that zeroing in on a few tasks to do well and repeatedly (delivery, laundry, floor-cleaning, etc), in ADA-compliant environments (hotels, hospitals, airports), was a much less scary place to start.
