A remote pet feeder control system via MQTT protocol

Currently, most commercial pet feeders are stationary machines. Owner can control the feeder to throw food at their pet in a remote mode through a smartphone. Some feeders also have a camera function that allows the owner to observe the pet at home through the camera. However, these machines are stationary and can hardly move. The pictures are also in a fixed shooting angle, yet pets may move around the house. Therefore, this paper will design a remote control system on a toy car that is equipped with an IP camera, feeding stuffs and water. It allows the owner not only to receive the image captured by the remote camera through a mobile device, but also to control its movement through MQTT protocol to achieve the purpose of pet feed and water supplement.
