NAO V6 is a 58 cm, 5.48 kg, 25-DoF bipedal humanoid sold by RobotLAB for $16,990 and Generation Robots for €10,020 incl VAT. It uses an Intel Atom E3845 with 4 GB RAM, two 5 MP cameras, four microphones, sonar, tactile sensors, and a 62.5 Wh battery rated for 60-90 minutes. About 20,000 units have reportedly been sold in 70 countries; USC has 12 units. It is an education/research platform with Choregraphe, Python, and C++. Autonomy is claimed but not independently benchmarked; video demos exist but were title-only in this review. No payload, walking speed, hand DoF, or manipulation demos were found

EngineAI PM01 is a compact Chinese bipedal research humanoid listed as 1.38 m, about 40 kg, 24 DOF, 2 m/s, with 320-degree waist rotation and a third-party video title claiming a front flip. Official sources confirm the platform and an official introduction video, but no payload, runtime, battery, hands, sensors, autonomy task execution, manipulation, or named customer deployments have been found. Price is uncertain: a third-party video title says $13,700, while a commonly cited 88,000 yuan launch price belongs to SE01, not PM01. Treat as a purchasable motion/research platform with low confidence on reliability and commercial readiness
