Positive visions of the future always involve robots doing tasks we would rather not do. As time goes on we seem to be getting closer to that goal. Not long ago I wrote about the Lawnbot which was a robotic lawn mower. Now there are robotic vacuum cleaners to take care of cleaning our floors. You may have already seen or even have the Roomba which has been on the market for a few years now. Jumping ahead in technological features is the Cocorobo robot vacuum by Sharp. More than just a vacuum, it has a lights, a camera, smartphone communication, and you can even have a conversation with it!
