A lot of the robotics invasion will be, as you say Bert, continuing evolution of the product we already have in our home. The big challenge, as I see it is with the steps in between.
For example, it's not a stretch to see the clothes washing and drying process being completely automated from the point at which you toss dirty clothes in until they are dry and ready to put away. In that stage, we won't even really notice because those things will be just more features thrown at us by the sales people.
We will have to sit up and take notice when we put robots outside of that - putting the clothes away, gathering the dirty clothes, distributing them to each respective family member.
Well, you know, this "robotics" stuff is really just a continuing evolution. not something new.
We've had robots doing house chores for many decades. In the form of washing machines, dishwashers, garage door openers, kitchen dispoers, even vacuum cleaners. All chores that were previously done by people.
