My first robot that worked out was the Roomba

Now we have the Alexa and a Roomba or Neato for each floor of the home.
Robots are going to get there but I think what held them back was trying to cram all the code and data into that robot frame.
Today with Google Home, Alexa, Siri and others their data is finally off the robot's own frame and we are seeing big strides forward.
