| Out of the box | The most polished no-code experience here: autonomous life mode, speech recognition in ~20 languages, face and object detection, walking, and drag-and-drop Choregraphe programming, all working day one. Proven in classrooms and therapy for over a decade. | Ships with working RoboCup soccer and vision demos (ball tracking, kicking), walking gaits, and full example stacks. It is the reference kid-size platform, but expect a Linux terminal, not a phone app. |
| Development access | NAOqi OS + Choregraphe with Python/C++/Java SDKs and a huge education ecosystem. Closed-source firmware, and the post-receivership update roadmap is uncertain. | Fully open source in hardware AND software, alongside Fourier N1 the most open commercial platform here: 20 torque-controlled Dynamixel actuators, OpenCR sub-controller, complete docs. The 2025 re-release is native ROS 2. |
| Best for | Educators and HRI researchers who want a proven, no-code, endlessly documented teaching humanoid. | University coursework and RoboCup teams that want a fully open, torque-controlled bench platform. |
