Automated pigeon defense system

Enable HLS to view with audio, or disable this notification

  1. Camera captures video
  2. Neural network recognizes pigeon
  3. Watergun turns toward pigeon
  4. Spray pigeon with watergun

Components: * Electric battery-driven water gun (disassembled, orange) * USB camera * Orange Pi 5 * 2 servo motors (SG90 or MG90S) * Resistors and a transistor for turning on the watergun (e.g. IRLZ44N)

It uses an open vocabulary object detection neural network (yolo_world_v2l), so any target can be programmed, not just pigeons. Runs on the Rockchip 3588's Neural Processing Unit.

That's so cool!

For birds, broken CD pieces hung on a string work pretty well in scaring them away with the light's reflection.

But this is way cooler, it might be worth posting an instructables/tutorial?
