Booster K1 vs EngineAI PM01

Booster K1 is a compact (95 cm, 19.5 kg) bipedal humanoid from Booster Robotics (China), positioned as an entry-level research/education platform with 22 DoF, up to 200 TOPS compute, stereo depth camera, voice interaction, and official walking speed 2 m/s. It is purchasable from distributors from about $4,999 (limited launch offer) to €9,000 or $11,998 depending on region. Its strongest validation is being the platform of the winning team in RoboCup 2025 KidSize league. However, most capability claims (autonomous soccer, balance recovery, durability) are company-asserted without independent verification, and video demos lack transcripts. No hand dexterity, payload, or per-model shipment data is available

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
