Complete CAD drawings, firmware, control code, and simulation tools are all public. Under the CERN Open Hardware License, free secondary development and commercial licensing are supported.
Bilateral force feedback for smooth human-like control with real-time gravity compensation, ideal for contact-rich teleoperation and real-world data collection.
Native ROS2 / BrainOS middleware support for node development, topic communication, simulation debugging, and multi-robot coordination, compatible with MuJoCo and Isaac Sim.
Deeply aligned with China's joint motor supply chain, with fully domestic IP. Manufacturing licenses are freely open to all domestic manufacturers.
Listed as an official data-collection device in Hugging Face's LeRobot framework, supporting imitation learning, RL, and VLA model deployment.
Flexibly adapts to wheeled, legged, and other chassis, supporting three DIY configurations: Station, Strench, and Heavy.
OpenArm focuses on cross-disciplinary engineering practice, with five course categories covering core undergraduate and vocational courses.
Tailored colors, logos, and course adaptation packages for your institution
Arm body, controller shell, and teaching materials can embed your logo and name for a campus-exclusive identity.
Custom course content, lab projects, training programs, and assessments matched to your major and syllabus.
Combine the OpenArm ecosystem with campus research to build a teaching-training-competition-research platform.
Over ten universities have adopted OpenArm as a training platform for national robotics and vocational skills competitions.
10+ undergraduate institutions already use OpenArm in regular courses and research. We offer brand customization, course adaptation, and competition support in one package.
