SO-ARM100

SO-ARM100 is a open robot arm from HF/RobotStudio, catalogued as Open robot arm in the Open robotics / embodied AI meta-category. Its primary job is open robotics / embodied AI platform for builders who need an inspectable path rather than a sealed appliance. In practice it targets: Low-cost open 6-DoF arm for LeRobot; Leader–follower teleop kits available; and 3D-printable structure; community BOM.

Openness is listed as open. Technology notes in this catalog point to: Feetech STS/SMS bus servos; Waveshare / OpenRB-class controllers; and Hugging Face LeRobot integration. Heavy models usually sit on a phone, SBC, or edge box; the device itself is the sensor, array, camera, brain, or actuator surface depending on class.

For an agentic operating system this is an act surface: open arms or bases let teleop and learned policies close the loop from proposal to physical motion. Catalog possibilities include Cheap manipulation demo collection; Pair with OAK / reCamera / Voice PE as eyes+ears; and Classroom / research without six-figure arms.

Limit: Amazon is parts-only here; primary buy remains HF/RobotStudio; Amazon=parts.
