An Amazon engineer has created a smart door for cats, which prevents them from entering with prey that they have hunted outside the home.
After the adorable appearance of a kitten there is a hunter; In their genes there are still the instincts that their ancestors had before humans went out of their way for their welfare. They may not lack food, but they still try to hunt; and the worst is that they can bring the prey home, as a “gift” for humans. It is the problem that had Ben Hamm, an Amazon engineer, who tired of finding mice and other dead animals at home decided to invent a method to avoid it.
But of course, we are talking about an engineer, so his solution is as cool as it is too complicated. It is a door controlled by Artificial Intelligence, able to know if the cat brings a prey between the teeth or if it comes alone. In case the cat brings a mouse or bird, the door will refuse to open, which at least can teach a lesson to the cat.
A smart door for cats
For this smart door, Hamm has used DeepLens, a camera system with Artificial Intelligence that uses machine learning to analyze the images it captures. Although initially DeepLens was thought for business, Hamm programmed it to detect if the cat had something in its mouth when it approached the door. The system was trained by Hamm himself based on photographs of his cat with prey. In this way, the camera is able to detect four different states: “There is no cat”, “There is a cat but it is not approaching”, “There is a cat and it is approaching”, and “Cat with prey”.
If this last condition is met, the door remains closed for fifteen minutes, and Hamm receives a notification on his mobile thanks to an Arduino board. In addition, an automatic donation is also made to a bird protection society, since they are the main victims of their pussycat. It is even possible that this system helps to teach the cat, although it is unlikely; After a quarter of an hour, the door opens so as not to leave the poor person outside.
It may seem like something excessive, but it is a demonstration of what will be possible once the cost of access to the AI goes down.
