Xiaomi CyberOne is a full-size bipedal humanoid robot developed by the Xiaomi Robotics Lab, a division of the Chinese technology company Xiaomi. Unveiled on August 11, 2022, at a product launch event in Beijing, CyberOne stands 177 cm tall and weighs 52 kg, featuring 21 degrees of freedom, a self-developed emotion recognition engine capable of detecting 45 human emotional states, and a proprietary depth vision module for three-dimensional spatial perception. The robot was introduced by Xiaomi founder and CEO Lei Jun, who received a flower from CyberOne on stage during the demonstration. With an estimated production cost of 600,000 to 700,000 yuan (roughly $89,000 to $104,000) per unit, CyberOne was not designed for commercial sale but instead serves as a technology demonstrator for Xiaomi's long-term ambitions in artificial intelligence, robotics, and smart ecosystem integration.
CyberOne is the successor to Xiaomi CyberDog, a quadruped robot released in 2021, and represents Xiaomi's progression from four-legged robotics to full bipedal humanoid systems. As of early 2026, Xiaomi has begun testing updated versions of its humanoid robots in its electric vehicle factory, with plans to deploy them at scale within five years.
Xiaomi was founded in 2010 by Lei Jun and has grown into one of the world's largest consumer electronics companies, manufacturing smartphones, smart home devices, wearables, and a wide range of Internet of Things (IoT) products. The company's AIoT (AI + IoT) ecosystem connects over 500 million smart devices worldwide through its XiaoAI voice assistant and Mi Home platform. In 2024, Xiaomi expanded further into the automotive sector with the launch of its first electric vehicle, the Xiaomi SU7 sedan, as part of a broader "Human x Car x Home" smart ecosystem strategy.
Xiaomi established its Robotics Lab in August 2021, signaling a formal commitment to robotics research and development. The lab's first product was CyberDog, a quadruped robot inspired by platforms like Boston Dynamics' Spot. CyberDog was powered by an NVIDIA Jetson Xavier NX processor, featured 11 degrees of freedom, and was priced at just 9,999 yuan (approximately $1,540). Xiaomi released 1,000 units to fans, engineers, and researchers, and made the robot's system code and mechanical blueprints open source to foster a collaborative development community.
The success of CyberDog provided Xiaomi with foundational experience in servo motor design, AI-driven locomotion control, and sensor integration. These capabilities became the building blocks for CyberOne, which represented a significant leap in complexity from a quadruped to a bipedal humanoid form factor.
Rather than competing directly on athletic performance against robots like Boston Dynamics' Atlas, Xiaomi designed CyberOne with a focus on human-robot interaction and emotional intelligence. Lei Jun stated that "CyberOne's AI and mechanical capabilities are all self-developed by Xiaomi Robotics Lab," noting that the company invested heavily in research spanning software, hardware, and algorithm innovation. Lei Jun has described intelligent robots as a future component of everyday life, envisioning them as companions and assistants rather than purely industrial machines.
The robot's humanoid proportions were deliberately chosen to match an average adult human, standing 177 cm tall with an arm span of 168 cm. This design decision was intended to allow the robot to navigate human environments and interact naturally with people.
Xiaomi CyberOne was officially unveiled on August 11, 2022, at a major Xiaomi product launch event held in Beijing. The event also featured the announcement of the Xiaomi Mix Fold 2 foldable smartphone. CyberOne's debut came just weeks before Tesla's AI Day on September 30, 2022, where Elon Musk presented the first prototype of Tesla Optimus (also known as Tesla Bot).
During the on-stage demonstration, CyberOne walked out to meet Lei Jun, greeted the CEO, and reportedly said, "Hi Lei Jun, you are taller than I thought." The robot then presented Lei Jun with a long-stem red flower, showcasing its ability to grasp and hand over objects. CyberOne also performed a kung fu pose and posed for a selfie with Lei Jun, reacting to the applause and delight of the audience. The demonstration, while modest in terms of acrobatic capability compared to Boston Dynamics robots, effectively illustrated CyberOne's ability to walk bipedally, recognize and interact with a specific individual, and manipulate objects with its hands.
The timing of CyberOne's unveiling was widely interpreted as a strategic move by Xiaomi. By demonstrating a functional walking humanoid robot before Tesla could show its own, Xiaomi positioned itself as a serious competitor in the emerging humanoid robotics space. When Tesla's Optimus prototype was finally shown at AI Day 2022, it was noticeably more primitive in its movements compared to what CyberOne had demonstrated weeks earlier.
CyberOne was subsequently showcased at Mobile World Congress (MWC) 2023 in Barcelona, bringing the robot to an international audience and further establishing Xiaomi's presence in the global robotics conversation.
| Specification | Value |
|---|---|
| Height | 177 cm (5 ft 10 in) |
| Weight | 52 kg (115 lb) |
| Arm span | 168 cm |
| Degrees of freedom | 21 |
| Maximum walking speed | 3.6 km/h (2.2 mph, 1 m/s) |
| Single-hand payload | 1.5 kg |
| Joint response time | 0.5 milliseconds |
| Face display | Curved OLED module |
CyberOne's body proportions closely approximate those of an average adult human. The robot's relatively light weight of 52 kg is achieved through careful engineering of its structural components and actuator systems. A curved OLED display is mounted on the robot's face area, showing real-time interactive information such as status indicators and emotional feedback.
Xiaomi developed custom actuators specifically for CyberOne, rather than relying on off-the-shelf components. The upper limb joint motors weigh only 500 grams each while delivering a rated output torque of up to 30 Nm. These compact motors achieve a power density of 96 Nm/kg, reflecting precision engineering that requires specialized manufacturing facilities and quality control processes.
The hip joint actuators are considerably more powerful, producing an instantaneous peak torque of up to 300 Nm. This level of torque is necessary for maintaining balance and enabling stable bipedal locomotion, as the hip joints bear the majority of the robot's weight during walking and turning.
All 21 degrees of freedom achieve a real-time response speed of 0.5 milliseconds, allowing CyberOne to make rapid adjustments to maintain balance and simulate natural human movements. Six degrees of freedom are allocated to each arm, enabling a range of gestures and object manipulation capabilities.
CyberOne's primary perception system is built around Xiaomi's self-developed Mi-Sense depth vision module, which provides three-dimensional spatial recognition. This proprietary module is combined with an Intel RealSense D455 RGB-D camera, a commercially available depth sensor that offers stereo depth perception, a global shutter RGB sensor, and an integrated inertial measurement unit (IMU).
Together, these components enable CyberOne to perceive its three-dimensional environment, recognize individual people, interpret gestures, and read facial expressions. The vision system feeds data into Xiaomi's AI interaction algorithms, which process spatial information in real time to guide the robot's navigation and interaction behaviors.
One of CyberOne's most distinctive capabilities is its emotion recognition system, which uses two proprietary Xiaomi AI engines:
| Engine | Capability |
|---|---|
| MiAI Vocal Emotion Identification Engine | Recognizes 45 classifications of human emotion from voice |
| MiAI Environment Semantics Recognition Engine | Identifies 85 types of environmental sounds |
The MiAI vocal emotion identification engine analyzes vocal tone, pitch, cadence, and other acoustic features to classify a speaker's emotional state into one of 45 categories. This allows CyberOne to detect when a person is happy, sad, angry, or experiencing other emotional states, and to respond accordingly. According to Xiaomi, the robot can detect happiness and even comfort users in times of sadness.
The MiAI environment semantics recognition engine processes ambient sounds to identify 85 distinct types of environmental audio, such as alarms, music, speech from multiple sources, and other contextual sounds. This gives the robot situational awareness beyond what its vision system alone can provide.
Both engines were developed entirely in-house at the Xiaomi Robotics Lab, reflecting Xiaomi's strategy of maintaining full control over its core AI technologies.
CyberOne runs on a custom computing platform developed by Xiaomi. Reports indicate the system includes enterprise-grade processing hardware, with some sources citing dual Intel processors and NVIDIA computing modules for handling the robot's AI workloads. Each joint is managed by custom DSP-based (digital signal processor) controllers that enable the 0.5-millisecond response times. The computational requirements of running real-time emotion recognition, depth vision processing, locomotion control, and interaction algorithms simultaneously demand significant processing power, contributing to the robot's high per-unit production cost.
CyberOne supports WiFi and Bluetooth connectivity, enabling wireless communication with other devices in Xiaomi's ecosystem. However, unlike CyberDog, which was released with open-source software and an API for developers, CyberOne does not offer a publicly available API.
The near-simultaneous unveiling of Xiaomi CyberOne and Tesla Optimus in 2022 drew immediate comparisons between the two humanoid robots. Both were announced by companies better known for consumer products (smartphones and electric vehicles, respectively) rather than robotics, and both were positioned as early steps toward long-term humanoid robotics ambitions.
| Feature | Xiaomi CyberOne (Aug 2022) | Tesla Optimus Gen 1 (Sep 2022) |
|---|---|---|
| Height | 177 cm | 172 cm |
| Weight | 52 kg | 57 kg |
| Degrees of freedom | 21 | 28 (later versions) |
| Walking speed | 3.6 km/h (2.2 mph) | Up to 8 km/h (5 mph) |
| Key differentiator | Emotion recognition, depth vision | Manufacturing focus, Tesla AI stack |
| Demo quality (2022) | Walked, talked, handed flower | Walked unassisted (barely), waved |
| Production cost | ~$89,000 to $104,000 | Not disclosed (targeted under $20,000 long-term) |
| Commercial availability | Not for sale | Not for sale |
At the time of their respective 2022 unveilings, CyberOne demonstrated more polished capabilities on stage, walking with relative stability and performing object manipulation, while Tesla's first Optimus prototype exhibited a slow, cautious gait. However, Tesla's Optimus program has since progressed rapidly through multiple generations, benefiting from Tesla's massive investment in AI infrastructure, its Dojo supercomputer, and data from its autonomous driving program. By contrast, CyberOne received comparatively fewer public updates in 2023 and 2024, leading some observers to question whether Xiaomi was continuing active development.
The two companies also differ in their stated goals. Xiaomi emphasized emotional intelligence and human interaction as CyberOne's primary value proposition, while Tesla has focused on creating a general-purpose robot for manufacturing and household tasks, with Elon Musk predicting that Optimus could eventually become Tesla's most valuable product line.
Xiaomi CEO Lei Jun stated that each CyberOne unit costs approximately 600,000 to 700,000 yuan to produce, equivalent to roughly $89,000 to $104,000 at the time of announcement. This high production cost reflects several factors:
Xiaomi has not offered CyberOne for commercial sale. The robot was positioned from the start as a research platform and technology demonstration rather than a consumer or industrial product. Lei Jun framed CyberOne as an investment in Xiaomi's future, stating that the experience and technology developed through the project would inform the company's broader AI and hardware strategy.
Following the initial August 2022 unveiling, CyberOne was showcased at MWC 2023 in Barcelona, where it was demonstrated alongside the CyberDog robot. Throughout 2023 and 2024, Xiaomi released incremental firmware updates that improved CyberOne's gait stability and natural language processing capabilities, though these updates received relatively little public attention.
In February 2026, Xiaomi announced Xiaomi-Robotics-0, a 4.7-billion-parameter open-source Vision-Language-Action (VLA) model. This model integrates visual perception, natural language understanding, and real-time robotic action generation into a single system, representing a significant advance in the AI software powering Xiaomi's robotics platform. By open-sourcing this model, Xiaomi followed the same community-driven approach it had used with CyberDog's software.
In early 2026, Xiaomi began testing humanoid robots derived from the CyberOne platform at its electric vehicle manufacturing facility in Beijing. The robots were deployed as what Xiaomi President Lu Weibing described as "interns" on the production line, performing tasks at a self-tapping nut assembly station in the die-casting workshop of Xiaomi's EV factory.
Key results from these factory trials include:
| Metric | Result |
|---|---|
| Task | Self-tapping nut installation (dual-side) |
| Success rate | 90.2% |
| Cycle time | 76 seconds (met production line requirement) |
| Continuous operation | 3 hours autonomous |
| Control system | End-to-end data-driven, reinforcement learning |
The robots used a hybrid motion control architecture that combined optimization-based control with reinforcement learning, processing multimodal inputs from vision, tactile feedback, and joint proprioception sensors. A system called TacRefineNet provided haptic perception, allowing the robots to use tactile feedback during manipulation tasks.
Lei Jun stated that Xiaomi plans to deploy "a large number" of self-developed humanoid robots in its factories within the next five years, while also exploring applications in household settings, which he described as a potential "trillion-yuan market."
In April 2026, Xiaomi unveiled a significantly upgraded bionic hand for the CyberOne platform, designed specifically for high-precision industrial environments. The new hand introduced several notable innovations:
| Feature | Specification |
|---|---|
| Volume reduction | 60% smaller than previous version |
| Scale | 1:1 human adult proportions (based on 1.73 m model) |
| DOF increase | 83% more degrees of freedom |
| Tactile sensing | Full-palm coverage, 8,200 mm2 |
| Durability | Over 150,000 grasping cycles |
| Thermal management | Liquid cooling via 3D-printed metal channels |
| Cooling rate | Evaporates 0.5 ml water per minute, 100W active cooling |
The thermal management system represents a particularly novel approach. Using 3D-printed metal channels running through the hand, the system circulates liquid coolant that evaporates at the surface, mimicking human perspiration. This "artificial sweating" allows the hand to dissipate 100 watts of heat, enabling continuous high-load operation without thermal throttling. Traditional tendon-driven robotic hands typically fail after roughly 10,000 grasping cycles; the new CyberOne hand exceeded 150,000 cycles in testing.
Xiaomi also open-sourced the TacRefineNet framework alongside 61 hours of raw tactile data to support broader research in robotic manipulation.
CyberOne fits within Xiaomi's broader corporate strategy of building an interconnected ecosystem spanning smartphones, smart home devices, electric vehicles, and now robotics. The company's progression from robotic vacuum cleaners to CyberDog to CyberOne to factory-ready humanoid robots reflects a deliberate, step-by-step approach to building robotics expertise.
Xiaomi's competitive advantages in the humanoid robotics space include:
Lei Jun has positioned robotics as one of Xiaomi's core long-term investments, alongside electric vehicles and AI. The company's willingness to invest in expensive prototype development (at over $89,000 per CyberOne unit) while forgoing immediate commercial returns signals a commitment to building capabilities for a future where humanoid robots could become a significant product category.
Critics and robotics experts have noted several limitations in CyberOne's demonstrated capabilities. The robot's walking gait, while stable on flat surfaces, appears slow and somewhat stiff compared to more advanced humanoid platforms. CyberOne cannot climb stairs, jump, or run in any meaningful sense. Its 1.5 kg single-hand payload capacity is modest for potential industrial applications.
IEEE Spectrum's Evan Ackerman published an analysis titled "Xiaomi Builds a Humanoid Robot for Some Reason," reflecting skepticism in the robotics community about the practical purpose of CyberOne at the time of its unveiling. The Interesting Engineering review noted that CyberOne displayed "pretty average dexterity and poor locomotion" compared to Boston Dynamics' robots.
However, CyberOne's emphasis on emotional intelligence and human interaction was recognized as a distinctive design choice. Rather than attempting to match the athletic performance of research robots with decades of development, Xiaomi chose to differentiate on the basis of perception, emotional understanding, and the potential for integration into consumer-facing environments.
The 2026 factory deployment results and bionic hand upgrade have gone some distance toward addressing earlier criticisms, demonstrating that Xiaomi has continued to invest in practical capabilities even during the period when CyberOne received minimal public attention.
