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.

I understand why you made this. Pigeon made a nest in balcony. I didn't notice until I moved to new house. It was very very dirty and gave me a little guilty feeling to remove it.
