OpenArm

OpenArm is an open-source 7DOF humanoid arm designed for physical AI research and deployment in contact-rich environments. With high backdrivability and compliance, it excels at safe human-robot interaction while delivering practical payload capabilities for real-world applications.

OpenArm features human-scale proportions, safety and compliance, and practical payloads. At $6,500 USD for a complete bimanual system, it provides a flexible platform for teleoperation, imitation learning, simulation, and real-world data collection in contact-rich tasks.

We're in continuous development and actively seeking contributors, research partners, and company collaborators to shape the next generation of practical humanoid systems. Ready to join the future of open-source robotics?
