DIY robot dog

A robotic dog can be made from cardboard. Unlike a real dog, “K-9” does not need to be fed and does not  go to the restroom in the house. Athough it is not real, it acts like a real dog. It can be programmed to wag its tail if you get near, or to turn off at a certain time. It can also be programmed to bark. It is touch activated so you can pet it, and voice activated, like trained dog.
