1.Introduction:

This project is an application of artificial intelligence image recognition in the scenario of stray animal protection. The project uses the built-in offline cat/dog detection function of the Unihiker K10. In this way, the Automatic Cat Feeder can accurately identify and serve stray cats in need of help. When the Cat Feeder recognizes a cat and detects that the cat has approached the cat food bowl, it will automatically dispense food for feeding. Other animals entering the recognition range will not be feed.

2.Operation Instructions:
Gradually move the cat model (or a photo of a cat) into the recognition zone. The Cat Feeder will identify the cat, and the cat food dispenser will activate to release food. As the cat lowers its head to eat, the cat face recognition frame will vanish. The K10 initiates a 10-second countdown. Throughout this period, the machine will refrain from dispensing additional food to prevent the issue of repeated feeding that can occur when a cat repeatedly lowers and raises its head while eating. If an alternative animal model, such as a pheasant model, is introduced into the recognition area, the K10 will not recognize it, and the cat food dispenser will remain inactive.

3.Material Preparation：

HARDWARE LIST

1 UNIHIKER K10

1 Gravity: Easy Relay Module

Link

1 Cat model

1 Pheasant model

1 Motor

1 3D-Print cat food dispenser

1 3D-Print K10 bracket

4.Production Steps：
(Tip: Before beginning assembly, ensure that the 3D printed parts are pre-printed. The files for the printed parts are located at the end of the article.)

STEP 1

Utilize an A3 display board and 3*3 cm supporting sponges to pad the top and bottom.

STEP 2

3D print the K10 bracket, secure it to the bottom plate of the K10 bracket using the K10 support fixing screw, install the K10, plug in the K10 power supply line and P1 port wiring respectively, and pass the two wires through the reserved hole in the bottom plate.

STEP 3

Assemble the 3D-printed cat food machine. Connect the relay, the cat food machine, and port P1 of the Unihiker K10. For guidance, refer to the pictures provided.

STEP 4

Place the cat food dispenser into the pre-dug hole, position the cat model, and organize the wire harness.

STEP 5

Pour the cat food beads into the cat food basin (it is recommended to use fewer than 25 beads, as using more may cause the beads to get stuck).

STEP 6

Complete the setup, power on the K10 and the relay, and begin the project practice.
