Our project is making a dog feeder that can be fully automated and is also usable for multiple pets, right now our project is doing its first generation, doing some prove of concept things as well as exploring the hardware capabilities and limitation
This started from my friend having multiple pet dogs and he stays away from home rather often. Due to the fact that he needed to work overtime often, he tasked us to make a system that can help feed his dogs together having just one feeder.
Hence, to resolve my friend (and other pet owner)'s problems, we have decided to make an automatic pet feeder that:
- ensure the dogs are well catered for and receives proper amount of food
- has to be adjustable to cater to different dog weights
- checks the food should also be checked if it is safe for consumption.
- notifies owner if feed is low
- able to clarify which dog wants to be fed
- Pet under/overeating can lead to higher risk of illness.
- Adult dogs should be eating approximately 30 grams of food per kg per day.
- According to European Pet Food Industry Federation (FEDIAF), a year supply of wet dog food one pet has a footprint of approximately 464kg of carbon dioxide, meaning pet food should not be wasted at all.
