Man Builds AI-Powered Pet Door That Prevents His Cat From Bringing Dead Animals Into The House

This is a video of Amazon engineer Ben Hamm's presentation during Ignite Seattle (please don't actually burn the city to the ground) in which he discusses the AI-powered cat door he built that prevents his cat Metric from being able to enter the house with dead animals. The door works with an Amazon DeepLens AI-enabled camera and an Arduino-powered lock. Some more info while I wonder why my cats don't love me enough to ever bring me home a snack:

The camera was loaded with machine vision algorithms trained by Hamm himself [using thousands of images captured of his cat]. They identified whether Metric was coming or going and whether he had prey in his mouth. If the answer was "yes," the cat flap would lock for 15 minutes and Hamm would get a text.

Hey, whatever works. I remember one time years ago one of my cats killed a mouse then brought it inside and ate it and the next time I went to clean the litter box it smelled so bad I puked in it. Even just typing this I started dry heaving a little. Memories, you know? "What about them?" Most of them are bad.

Keep going for the video.

Thanks to j zell, who agrees somebody needs to develop one of these for dogs with muddy paws.

    Keep your cat inside or on a leash, they are bird killing machines.

    "They identified whether Metric was coming or going..." haha, literally teaching it to know the ass from the face.

    Reminds me of a joke: Guy walks into a bar, bartender says, "Woah, we can't serve you. You're too drunk to see straight," to which the guy replies, "WAHT, Immnot drunhnk, I can shee fine, see, that cat commin' in, I can see it's only got ONE EYE!" The bartender replies, "That cat isn't coming in, it's going out!" FIN.

    When a cat brings you a dead animal it's a sign of affection, dolt! This is like if my wife locked me out of our house every time I brought flowers home.

  • Bling Nye

    Yes, if the flowers were body parts.

  • Nicholas Conrad

    Literally the plant's genitals. Ya'know,
    Georgia O'Keeffe was on to something.

  • The_Wretched

    Lady parts / plant hybrids?

    That's a marval villain right there.

  • Bling Nye

    ... well played, good sir. LOL

  • My old cat got out once and came back with what I thought was a dead baby rabbit. Then he dropped the rabbit, which proceeded to jump up and run all over the house. Took me half an hour to capture it and then I had to figure out where my cat got a live rabbit.
    This is one of many reasons why I'm a dog person.

    I feel like 15 minutes is a bit of a long time-out for a cat...

  • Joe S

    OR... you know... have an indoor cat that doesn't go around killing all the freaking native wildlife!

    Couldn't he make a scale that knows the cat's programmed weight without anything in it's mouth. So if the cat weighs a bit more in a short amount of time, it would be locked out, also would keep other cats out as well.

  • Octo

    Rain, etc. And a mouse weights what..a few tens of grams, that doesn't leave a lot of room for margin of error...if the cat drops a turd it wouldn't get in.

  • Deksam

    I did say a bit more, but yeah rain could be an issue.
