I'm looking forward to the day a small home robot can do the dishes, in the sink – replacing a dishwasher machine. This looks like a small step in that direction.
That’s the exact opposite of how most robotics are going for more specialized machines, not less. It is an interesting prospect, but what would be saved in space would be lost in more energy and water used (not to mention hygiene, we’ve used our dishwasher a lot more since we have had a kid to disinfect).
What if the dishwasher is sometimes run half-full?
And the arms can put clean things away!
