WowRobo OpenArm 2.0

The OpenArm 2 is an open-source humanoid robotic arm with 7 degrees of freedom (7-DOF), designed for research, education, and industrial prototyping. It combines a modular, human-like kinematic structure with high-quality manufacturing components, enabling precise manipulation in real-world environments. The system is part of an open ecosystem of hardware and software tools and is particularly suitable for physical AI, teleoperation, and data acquisition.
