Hyun-Seok Kim of Korea has recently come up with a prototype concept for a new robot floor cleaner called the Puppy Robotic, the cleaning robot is adorably cute and even plays music if you tell it to.
The Puppy Robotic is a set of four robot pups and one "mother dog". The four robot puppies go around the house, cleaning, and picking up small pieces of garbage they encounter. With their small sizes, these pups can enter small spaces just like a real puppy only these will clean under the bed not leave you little presents. When the pups are full of rubbish or are running low on battery, they return to the mother dog to dump the waste and to get powered up for another run.
When your house is completely clean, you can even play around with the pup robots by tossing a tracking device which the pups will attempt to follow. Though the puppy robots can if you attach the tracking device say to your dog who just came in from playing in the dirt or the kitty who tracks litter around the house the puppy robots will follow them around cleaning up their paw prints.
How do I get myself on the waiting list?
