Hello, I'm a student whom is currently working on a device which would be able to train a puppy to use the toilet inside completely automatically. The device would look something like a box. When the dog uses the toilet, the moisture system inside it detects it, sending a signal to the treat dispenser inside of it, feeding the puppy which would consequently allow it to learn where to pee every time. This device also includes various cool features such as an LED system which tells you how full the collector tray is (pee) and in addition, it provides you with useful data such as, when the dog last used the toilet via a timer which resets itself every time the moisture system/detector detects something. Please let me know what you think of my idea and if you have any questions.
