Stringman open-source room-scale cable robot debuts
What happened
On November 4, Hacker News featured Stringman, an open-source room-scale gripper robot priced at $795. It moves objects using four motors and cables anchored at the ceiling corners. In a 7×7×3 m room it averages a 1.9 kg net payload, up to 2.2 kg near the floor, and moves at about 0.4 m/s. The mechanical CAD, PCB and control software are all public, with local operation, a Python API, an MCP server and LeRobot support, plus a public dataset and training-data collection.
