Overview

SO-ARM100 / SO-100 is a community-favorite open low-cost arm design widely used with LeRobot teleop and imitation projects. It makes “real robot in the loop” accessible without industrial budgets.

Expect mechanical assembly, motor drivers, and safety limits to dominate your first week — software is the easy part once hardware is stable.

Learning Path (Real robot): preferred budget hardware entry.

Who it is for

Researchers, students, and builders comparing open embodied stacks.

Key highlights

  • Open low-cost arm designs popular with LeRobot teleop and imitation learning communities.
  • Type: project; categories: tool
