Automator is an open-source system for real-time automated imaging, tracking, and analysis of round Petri dishes/plates (90-100 mm). It integrates motion control, camera acquisition, and scheduling on Raspberry Pi hardware using Klipper, Moonraker, and a custom Python-based controller and web interface. Hardware design files are released under CERN-OHL-S-2.0; documentation under CC-BY-4.0.
