The SE01 is the flagship full-size humanoid robot from EngineAI (also stylized ENGINEAI), a Shenzhen-based company founded in October 2023 by Zhao Tongyang, who previously led XPENG's PX5 humanoid program. EngineAI's headline claim for the SE01 is a breakthrough in natural, human-like gait — achieved via an end-to-end neural network — moving past the "shuffling" small-step walk of earlier humanoids. The SE01 debuted in October 2024 and appeared on China's CCTV New Year's Gala.
Price Range
The SE01 went on global sale on December 24, 2024, in both commercial and educational versions, at an aggressive reported price of roughly $20,000–$30,000 (an early launch promotion offered it lower still).

Model Breakdown
The SE01 is EngineAI's full-size flagship. The company's lineup also includes the open-source education robot SA01, the lightweight high-dynamic PM01, and the heavy-duty industrial T800 (all covered below). The SE01 is the general-purpose industrial-leaning platform.
Buyer's Guide: What to Know
The SE01 is genuinely purchasable and aggressively priced. Available globally since late 2024 at a ~$20–30k level — a low price for a 32-DOF full-size humanoid.
Natural gait is the differentiator. EngineAI's end-to-end neural-network walking is the SE01's central pitch — long-stride, upright walking rather than a shuffle.
The joints are in-house. Self-developed harmonic/planetary/ball-screw modules with forced-air cooling are core to EngineAI's claims of stability and a long design life.
Plan around the ~2-hour battery. Quick-swap packs help, but extended operation needs spare batteries.
SE01 vs Similar Robots
- SE01 vs EngineAI PM01: Same maker — the SE01 is the full-size general-purpose flagship; the PM01 is the smaller, lighter, high-dynamic platform.
- SE01 vs Unitree H1/H2: All are full-size Chinese humanoids; the SE01 competes on natural gait and a low price.
- SE01 vs Kepler Forerunner K2: Both are aggressively priced Chinese industrial-leaning humanoids; the K2 emphasizes tactile hands and 8-hour endurance.
