🎯 Why

When I’m not home, my cats still need food. I started a new project and explored a few concepts to find a design I like.

✏️ Early sketches

🧱 3D visualization (Autodesk 3ds Max)

⚙️ Mechanics: water‑wheel drive

Printed all chassis parts for the hardware and spent time dialing in the water‑wheel mechanics so it runs smoothly.

🧠 DC motor mount iterations

A more fitted motor model:

First chassis prototype for the DC motor:

Smaller variant prototypes:

⏭️ Next steps

  • Calibrate portion size and rotation per feed.
  • Add sensors (jam detection / position).
  • Wire up controller + relays; plan enclosure.
  • Safety check for paws & fur near moving parts.
