SAO2
EngineAi’s SA02 is a pint-sized, anime-styled humanoid standing about 1.25 m tall and weighing only 25 kg, yet it squeezes in 26 powered joints plus two articulated fingers for expressive gestures. Dual HD cameras, an on-device large-language model and high-fidelity speakers let the robot recognise faces, answer homework questions and DJ a living-room karaoke night with almost no cloud latency.

Description
EngineAi’s new SA02 shrinks a full-body humanoid into a 1.25-metre, 25-kilogram frame that fits comfortably in living rooms and dorms. Its anime-inspired shell and softly lit face are meant to feel more like a friendly character than a piece of machinery, making the robot instantly approachable for teenagers and first-time robot owners.
Beneath that playful exterior, SA02 packs 26 actuated joints plus two articulated finger joints, letting it wave, point, dance and gesture with surprising nuance. Dual HD cameras handle object recognition and face tracking, while high-fidelity speakers give the robot a clear, expressive voice—turning everyday interactions into lively, multimedia experiences.
Conversation is driven by an on-device large-language-model that adapts to the user’s mood and context, so SA02 can switch from homework helper to karaoke host without cloud latency or privacy worries. Real-time perception and dialogue blend to create a companion that remembers preferences, cracks jokes and learns new household routines over time.
With a launch price of about US $5 300—less than many premium laptops—EngineAi is positioning SA02 as the most accessible full-featured humanoid to date. Pre-orders target tech-savvy youth and early adopters eager for hands-on AI, signalling a shift toward personal robots that are affordable, social and genuinely useful right out of the box.
