Stringman, an $800 open-source room scale gripper robot

Stringman is an open-source cable-driven robot priced at $795 that uses four motors to hang a gripper from ceiling-anchored lines, enabling it to reach an entire room with a payload capacity of up to 2.2 kg. Unlike traditional robotic arms that require multiple actuators and have limited reach, Stringman's design allows it to access the full volume of a room while being more cost-effective and computationally efficient, running locally on a user's network without sending data externally. The robot is fully open-source and certified by OSHWA, making it suitable for home labs and automation tasks.
