It’s not so doable as it turns out. The whole dancing routine can be preprogrammed once you figure out balancing and gross motor skills, which they did. But the dishes is fine motor skill, spatial awareness, object manipulation. It would be a lot easier if each plate, utensils and cooking ware would have a grip for robot grippers and a QR code, with a fixed cubby in the dish washer and cabinet. Lacking that, a lot more work needs to be done in better robot hands, perception, reasoning and manipulation.
