EngineAI PM01 vs LimX Oli

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

LimX Oli is a pre-order, 165 cm, 55 kg, 31-DoF biped research humanoid from LimX Dynamics, priced from RMB 158,000 (~$21,800). It has dual Intel RealSense depth cameras, a 6-axis IMU, modular design and slide-out battery, but no official payload, runtime, battery capacity or walking speed. The strongest public evidence is a secondary research summary reporting stair climbing of a 33-step spiral staircase in 12 seconds with zero falls, and benchmark returns of 0.85 for velocity tracking. Official video titles claim fully autonomous tennis ball picking and scalable autonomous deployment, but no transcripts or independent verification were found. No named customer deployment exists
