Xiaomi Robotics — CyberOne humanoid and the CyberDog quadrupeds
Xiaomi Robotics is the in-house robotics program of Xiaomi Corporation (HKEX: 1810), the Beijing-based consumer-electronics giant behind smartphones, IoT devices, and Xiaomi's electric-vehicle business. Since 2021 the division has built two headline platforms — the CyberDog and CyberDog 2 bio-inspired quadrupeds and the CyberOne full-size bipedal humanoid — positioning Xiaomi among the most vertically integrated players of the current humanoid robotics and general-purpose AI boom, alongside Tesla Optimus, Figure AI, Unitree, and Boston Dynamics.

About Xiaomi Robotics
Xiaomi Corporation was founded on April 6, 2010 in Beijing by Lei Jun and six co-founders, including Lin Bin. What began as a smartphone maker with an aggressive price-performance thesis has grown into one of the world's largest connected-device ecosystems: smartphones, wearables, smart-home appliances, and — since 2024 — electric vehicles. Xiaomi listed on the Hong Kong Stock Exchange in 2018 under the ticker HKEX: 1810 and reported roughly CN¥365.9 billion in revenue for 2024, giving the robotics division the balance sheet of a Fortune-scale parent to lean on.
Xiaomi's Robot Division was formally established internally in 2021. Its first public product was CyberDog, a bio-inspired quadruped unveiled in August 2021 alongside the Mi Mix 4 smartphone. Xiaomi launched CyberDog as an open-source developer platform: only about 1,000 units were built for the initial run, priced at roughly 9,999 yuan (about US$1,540), and the company explicitly targeted engineers, researchers, and Xiaomi Fans rather than a mass consumer market. It was Xiaomi's first legged robot and its first product to use in-house servo actuators, an NVIDIA Jetson Xavier NX compute module, and an Intel RealSense depth camera.
Twelve months later, in August 2022, Lei Jun personally introduced CyberOne at a Xiaomi launch event in Beijing — a 177 cm, 52 kg full-size bipedal humanoid nicknamed "Tie Da" (Big Iron). CyberOne widened the program's ambition from quadruped mobility to bipedal balance, manipulation, and human-facing interaction. In August 2023 Xiaomi followed up with CyberDog 2, a substantially smaller and cheaper (8.9 kg, ~12,999 yuan / US$1,785) Doberman-inspired successor built around Xiaomi's own CyberGear micro-actuators and a 19-sensor perception suite. Together the three platforms — plus the second-generation CyberOne unveiled in April 2026 — anchor Xiaomi's robotics roadmap.
Unlike the venture-funded startups it competes with, Xiaomi Robotics is fully owned by a publicly traded parent and is funded off Xiaomi's balance sheet rather than external rounds. That gives it deep access to Xiaomi's smartphone- and EV-scale supply chains, manufacturing capacity, and AI/IoT stack, but also constrains it: robotics is one of several strategic bets — alongside EVs and AI — competing for engineering and capital inside a much larger consumer-electronics business. The competitive landscape is crowded, with Tesla Optimus, Figure AI, 1X, Apptronik, Agility, Boston Dynamics, and China-domestic rivals such as Unitree, UBTECH, Fourier, and Xpeng all chasing the same general-purpose humanoid opportunity.
Product lineup: CyberDog, CyberDog 2, and CyberOne
Xiaomi's robotics catalog spans two form factors — bio-inspired quadruped and full-size humanoid — and roughly one platform release per year since 2021. The quadrupeds ship as limited-run developer devices; the humanoid remains a research-and-demo platform that Xiaomi has explicitly said it is not selling as a product.
CyberDog (2021) — the open-source quadruped debut
CyberDog was Xiaomi's first legged robot and its first foray into robotics beyond the earlier Roborock-branded vacuum ecosystem. A 14 kg quadruped built around 12 quasi-direct-drive BLDC actuators (32 N·m peak, 220 rpm) and an NVIDIA Jetson Xavier NX compute module, CyberDog walked at up to 3.2 m/s, could carry a 3 kg payload, and became widely known for its backflip demo. Only about 1,000 units were built for the initial launch, priced at 9,999 yuan (~US$1,540), and shipped with Ubuntu 18.04 + ROS 2 for developer experimentation.
CyberOne (2022) — the bipedal humanoid platform
CyberOne is the flagship of Xiaomi's robotics program: a 177 cm, 52 kg bipedal humanoid with an arm span of 168 cm and 21 degrees of freedom. Xiaomi developed in-house joint motors that weigh 500 g and deliver a rated 30 Nm at the upper-limb joints, with the hip motors capable of a 300 Nm peak torque. Each joint achieves a 0.5 ms per-DoF response, enabling the natural walking gait Xiaomi showcased at launch. On perception, CyberOne uses Xiaomi's proprietary Mi-Sense depth-vision module and MiAI engines to recognize 45 human emotions and 85 environmental sounds, with a curved OLED face module for interactive display.
CyberDog 2 (2023) — smaller, cheaper, more sensors
CyberDog 2 was a bio-inspired Doberman-style redesign focused on hobbyist and educational accessibility. Xiaomi cut mass by roughly 40% to 8.9 kg, shrank the footprint by ~16%, and re-worked the drivetrain around its in-house CyberGear micro-actuators. The perception stack expanded to 19 high-precision sensors — Intel RealSense D430 depth camera, YDLIDAR TG30 LiDAR, four ToF sensors, fisheye camera, force sensors on the feet, and a four-mic array — all fed into an NVIDIA Jetson Xavier NX. Xiaomi priced it at 12,999 yuan (~US$1,785) and shipped it on Ubuntu 18.04 + ROS 2 as an open developer platform.
CyberOne V2 (2026) — factory-tested successor
A second-generation CyberOne debuted at Xiaomi's Investor Day in April 2026. Xiaomi has not published a formal spec sheet, but company disclosures describe an adult-scale hand design with more than 22 degrees of freedom and evaporative "sweat gland" cooling. In early 2026 Xiaomi began piloting humanoid units on the assembly line of its Beijing EV plant, where two robots reportedly matched the plant's 76-second production takt during a three-hour continuous autonomous run of self-tapping nut installation. Xiaomi has explicitly said the platform is not for sale and framed the deployment as "interns," with a stated horizon of large-scale internal factory use within five years.

Technology stack
Xiaomi's robotics platforms combine in-house mechatronics — custom joint motors and the CyberGear micro-actuator family — with off-the-shelf best-in-class perception silicon and AI compute. Unlike some humanoid startups that vertically integrate everything, Xiaomi leans heavily on partners for the sensor and compute layers (Intel RealSense depth cameras, NVIDIA Jetson Xavier NX, YDLIDAR) and concentrates internal engineering on the actuators, control algorithms, and the MiAI perception models.
Perception
CyberOne's perception stack is anchored by Xiaomi's proprietary Mi-Sense depth-vision module — an Intel RealSense D455 RGB-D camera in the head — supplemented by a Microstrain 3DM-GX5 IMU in the torso and rotary encoders plus custom force/torque sensors on the limbs. CyberDog 2 pushes the sensor count to 19: RealSense D430 depth, YDLIDAR TG30 LiDAR, a 13 MP AI-interactive camera, RGB camera, 146° fisheye, four ToF modules, ultrasonics, UWB, force-sensitive foot pads, and a four-microphone array. That much heterogeneous sensing is what enables backflips, stair climbing, follow-me behavior, and real-time obstacle avoidance from a consumer-scale platform.
MiAI models and control
CyberOne uses Xiaomi's MiAI environment semantics recognition engine and MiAI vocal emotion identification engine to recognize 85 environmental sounds and 45 human-emotion categories. On the motion side, Xiaomi developed a self-authored humanoid bipedal control algorithm to coordinate the 21 degrees of freedom at a 0.5 ms per-joint response. The CyberDog family runs Ubuntu 18.04 + ROS 2 and exposes a Python control application plus an Android app, with SDK access designed to draw an external developer community — the same open-source ethos Xiaomi has used across its wider hardware ecosystem.
Actuators, power, and compute
Xiaomi builds its own actuators for both product families. On CyberOne, the upper-limb joints are 500 g brushless-DC (BLDC) modules rated at 30 Nm, with the hip joints delivering up to 300 Nm peak. Each is a fully integrated unit — frameless torque motor, harmonic gearbox, force/torque sensor, dual absolute rotary encoders, and a DSP-based joint controller. CyberDog 2 uses the smaller CyberGear micro-actuators, which Xiaomi has since spun out as a stand-alone module for developers. Compute is split between an Intel Core i7-class Xeon quad-core CPU and an NVIDIA Jetson Orin NX on CyberOne, and a Jetson Xavier NX on the CyberDog family. Onboard power on CyberOne is a 1.65 kWh lithium-ion pack rated for about 2.5 hours of continuous operation.
Power management is a demanding subsystem for a robot of this class. Each joint's servo controller must deliver hundreds of watts of instantaneous torque without thermally throttling, which drives the use of high-efficiency wide-bandgap semiconductors — SiC and GaN — in the motor-driver stages and requires tightly matched precision passives on every gate-drive and current-sense channel. The onboard battery pack integrates cell balancing, thermal management, and multi-stage protection ICs, and MLCC capacitors are stitched across every power and signal rail. The reliability of these components — many of them automotive-grade — is often the practical ceiling on how long a humanoid platform can run between charges.
Applications and deployments
Xiaomi Robotics has three overlapping markets: internal factory automation, developer / research platforms, and — eventually — consumer or service robots. The current stated near-term priority is factory use inside Xiaomi's own manufacturing operations, with home and service applications framed as a later horizon.
- Xiaomi EV plant, Yizhuang (Beijing). The most concrete deployment. CyberOne V2 units have been piloted on the automotive assembly line since early 2026, handling self-tapping nut installation, badge installation, console-panel sorting, and material-box handling. Xiaomi reports a ~90.2% success rate on nut installation across a three-hour continuous autonomous run at the plant's 76-second production takt.
- Xiaomi smartphone smart-factory (Beijing "Black Lighthouse"). Reported supervised trials of a next-generation humanoid on Xiaomi's highly automated smartphone line, covering component transport, visual inspection, cable routing, and simple screw placement.
- Developer and research platforms. CyberDog and CyberDog 2 shipped to engineers, universities, and robotics enthusiasts globally as open-source, ROS 2-based research quadrupeds — a channel Xiaomi has used to seed external development and gather field data.
- Future consumer and service robots. Lei Jun has publicly framed the factory floor as a "training ground" for eventual home-assistant products, with a repeatedly cited five-year horizon for large-scale internal deployment before broader rollout is even considered.
The robotics supply chain — where Hybrid Electronics fits in
A modern humanoid robot is one of the most component-dense products ever built. A single CyberOne-class platform depends on thousands of individual electronic components: precision BLDC motor drivers, high-torque servo modules, IMUs and 6-DoF force-torque sensors, LiDAR and time-of-flight modules, GPU compute boards, battery-management ICs, wide-bandgap SiC/GaN power semiconductors, high-speed board-to-board connectors, precision resistors, and thousands of MLCC capacitors distributed across every power and signal rail. Xiaomi's quadruped platforms alone integrate 11-to-19-sensor arrays; a CyberOne-class humanoid multiplies that count several times over.
Building that kind of hardware puts enormous pressure on the electronic-components supply chain. Prototype pilots and low-volume production runs frequently hit allocation, EOL notices, and long lead times on the exact parts they need, and R&D and field-service teams routinely have to support older platforms that use semiconductors no longer in mainstream distribution. During the current humanoid robotics and general-purpose robot AI boom, this pressure is amplified: dozens of well-funded teams — Xiaomi included — are chasing the same short list of high-torque BLDC drivers, precision IMUs, GPU compute modules, and automotive-grade power semiconductors, and franchise stock on many key parts is now measured in months of lead time rather than weeks.
Hybrid Electronics has been sourcing electronic components for industrial and embedded systems since 1995. For robotics teams — humanoid, mobile, industrial, and research — we specialize in finding the parts you need when mainstream distribution can't:
Obsolete and end-of-life parts
Legacy semiconductors, sensors, connectors, and passives that are no longer in mainstream distribution — the parts that keep older platforms running during transitions to newer hardware, and the long-tail items that block a BOM from closing.
Allocated and hard-to-find active parts
High-torque BLDC motor drivers, IMUs and MEMS sensors, SiC/GaN power devices, GPU compute modules, precision resistors, and MLCC capacitors caught in allocation or long-lead times. Send us a BOM or a shortage list — we'll confirm what we can source and at what lead time.
