EngineAI PM01 vs K-Scale K-Bot

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

K-Scale K-Bot was an open-source humanoid robot from K-Scale Labs (Palo Alto) with reported specs of 1.4 m height, 34 kg weight, 10 kg payload, 4-hour battery life, modular compute, swappable end effectors, and a starting price of $10,999. It targeted developers with an open-source RL library and sim2real pipeline. The company shipped a small number of Founder's Edition units and demonstrated low-latency teleoperation, but canceled all pre-orders and refunded deposits in November 2025 after failing to raise funding, then open-sourced hardware (CERN-OHL-S-2.0) and software (MIT). No autonomous operation, DoF, walking speed, or independent benchmarks were found
