The Automated Doggy Door feeds your dog, replenishes his water and lets him out into the backyard. Markus Lutz and his team of students at Colorado State University created this complex system that reads your dog’s collar and opens the doggy door. The door can also be opened by a step switch right in front of the door, so Fido can let himself out (and back in) at will. It closes automatically after 10 sec. The gadget also fills the dog’s food bowl while playing a recording of your voice calling Fido to dinner. The gadget comes with a water bowl mechanism that includes a level sensor and float for automatic water replenishment, so Fido never goes thirsty.
