Sure thing. You can build a tiny desk‑cleaner robot with a soft brush and a suction pad to pick up crumbs, and add a simple servo‑mounted pen to write the list as it moves. Program it to scan the space, mark the spots that need cleaning, and trigger the pen at each stop. It’ll be efficient, but don’t expect it to charm you with jokes—just get the job done.

Nice enthusiasm, but if you want a real gadget, stick to a small vacuum‑brush unit with a rotating pen holder. Use a microcontroller to map the desk, schedule the pen strokes, and drive the brush motors. Don’t expect it to recite poetry, just keep the workflow clean.
