Original prompt
Cat litterbox auto-cleaner. PIR detects when the cat leaves the box. After 60 second cooldown, a small scoop on a rail runs once across the box pushing waste into a sealed bin. Lid closes between cleanings. 3D-printed parts, two NEMA 17 steppers, ESP32. The bin gets emptied weekly instead of daily.
