Muse QC Cell

muse-qc-cell is an agentic quality inspection cell for injection molded parts, running on real hardware. A low-cost reBot Arm B601-DM picks each part from the table with a touch-sensing gripper, carries it to an inspection station and sorts it into a good or a bad box. A Muse Spark agent runs the cell from one order in plain words, typed or spoken: it scans the table, chooses the sort order, and rescans and replans when a part was moved, a grip missed or a new part appeared. SAM 3.1 finds the parts on the table and counts the levers of each part in an arm camera close-up. The rule is fixed in code (exactly 3 levers = good), so the model can never put a part into the good box. Results on the real arm: 10/10 parts sorted correctly in a 10-part session (4 min 39 s), and in a 19-minute long run with parts added and moved by hand, 33 of 33 lever counts were correct and no bad part ever reached the good box. Every human hardware run is logged in docs/DEVLOG.md, and 1051 offline tests run in CI. Only the touch-sensing gripper existed before the event (listed under "DIY Soft Finger" in the official Seeed reBot-DevArm repo); everything else, including all code, was built during the hackathon.
