Xiaomi Unveils Full‑Size Humanoid Robot CyberOne: Technical Overview and Industry Context

Xiaomi announced its full‑size humanoid robot CyberOne during Lei Jun's annual speech, showcasing a prototype that interacts directly with the audience rather than a simple PPT or costume performance.

The robot follows the "service‑human" approach, aiming to study human perception, cognition, decision‑making, and execution to better assist people, differentiating it from "surpass‑human" and "replace‑human" robot strategies.

CyberOne stands 177 cm tall and weighs 52 kg, featuring a semi‑transparent facial mask with OLED lighting and a 2D curved display module for real‑time emotion expression.

Its motion capabilities rely on high‑performance, miniaturized electric motors: a 500 g upper‑limb motor delivering 30 N·m torque, and a hip motor with a peak torque of 300 N·m, combined with proprietary biped control algorithms for stable walking.

The robot can grasp objects up to 1.5 kg with a single hand, and its design favors dry‑system high‑efficiency motors over bulkier hydraulic solutions, aligning with trends in electric vehicle technology.

CyberOne’s perception stack includes a depth camera paired with AI vision algorithms to generate 3D models for obstacle avoidance, as well as a "万物追焦" (all‑thing focus) feature that tracks key objects, and an audio system capable of recognizing six emotional speech categories and 85 environmental sounds.

It also supports a "drag‑teach" learning mode, allowing the robot to be guided through tasks similarly to a child learning to use chopsticks, requiring highly responsive joint actuation.

The article discusses the inherent difficulty of building full‑size humanoid robots, noting their status as the "crown jewel" of robotics due to complex mechanical design, multimodal perception, and high development costs.

Despite these challenges, Xiaomi pursues the robot to integrate and evolve its existing technologies—spanning smartphones, wearables, smart home, autonomous driving, and AI—into a platform that can serve human daily life across home, work, travel, and rest scenarios.

Strategically, the robot aligns with China’s "14th Five‑Year" robotics development plan, which emphasizes service robots for various industries and public sectors, highlighting the broader national push for advanced robotics.

Overall, CyberOne demonstrates significant progress in perception, cognition, and actuation, yet acknowledges that widespread commercial adoption of humanoid robots remains a long‑term endeavor.
