N2

The Noetix N2 is a pioneering child-sized humanoid robot developed by Beijing-based Noetix Robotics, founded in September 2023. Standing at 118 cm tall and weighing 30 kg, the N2 features a lightweight bionic structure optimized for agility and safety in human environments. Its architecture centers on 18 degrees of freedom (DoF): 4 DoF per arm (8 total) and 5 DoF per leg (10 total), enabling highly dynamic motions such as continuous backflips, front flips on uneven grass, long-stride running at up to 3.2 m/s (11.5 km/h), autonomous obstacle avoidance, terrain adaptation, and resistance to dynamic interference. Powered by 48V DC geared motors with encoders and peak knee joint torque of 150 N·m, the robot employs pure electric drive for precise control. The control stack runs on an open Linux OS with Python/C++ and ROS compatibility, leveraging a Rockchip RK3588s 8-core processor delivering 6 TOPS edge compute (upgradable to 67 TOPS with optional NVIDIA Jetson Orin Nano Super in EDU edition, including 4+32GB/8GB memory). AI integration is embodied intelligence-focused: deep reinforcement learning (RL) algorithms generate anthropomorphic walking gaits, while LLM-powered speech and visual interaction modules enable natural voice commands, 3D perception-based navigation, and multimodal responses. Perception relies on dual structured-light depth cameras (640×400 @ 12 fps, <3 mm error at 0.5 m)—one forward-facing and one downward-angled—for millimeter-grade 3D mapping, supplemented by 4 microphones and 1 speaker. Battery is a swappable 48V/7 Ah lithium pack offering 1-2 hours runtime (or 2.5 km continuous walking), quick-charged or swapped in under 5 seconds. Structural materials include aluminum alloy chassis for low inertia and high-strength shells for drop resistance (tested from heights in labs). Connectivity via Ethernet, HDMI, USB supports secondary development with high/low-level motion APIs. Real-world deployments highlight rapid scaling: by August 2025, Noetix produced 105 N2 units in one month, shattering production records. The N2 secured 2nd place in the world's first humanoid half-marathon (3h37m), performed at Beijing Dance Academy and UNESCO Paris events, endured abuse tests (kicks, falls), pulled 80 kg adults, and garnered 2500+ preorders at launch prices of $5.5k-$9k. Targeted for ToB/ToC in education (graphical programming), elder-care (companionship), home assistance, and research, it features ball-end effectors (0 fingers standard, swappable 5-finger for light manipulation up to 5 kg payload). Noetix's self-developed servos, motion algorithms, and closed-source stack (with open hooks) position the N2 as a versatile platform bridging demos to practical use, though full manipulation lags behind leaders. As of late 2025, production ramps for global sales (e.g., Russia at ~1.5M RUB), signaling China's push for affordable embodied AI.
