Why handful? I would assume that domestic robots like that would sell at least as many units as luxury cars - hundreds of thousands a year. In terms of training, there are a lot of current approaches of learning from videos (of which we have a lot) and from synthetic data, which is getting easier to generate. And if they need more data, I would assume that offering a version of such a robot with telemetry at a large discount would be an easy sell for some. In particular, I'd expect there would be a lot of demand for assistants to elderly people.
